New Equations Go Beyond Einstein’s Theory of General Relativity

Quantum Transfiguration of Kruskal Black Holes

Artist depiction of loop quantum gravity effects in a black hole. The bottom half of the image depicts the black hole which, according to general relativity, traps everything including light. Loop quantum gravity, a theory that extends Einstein’s general relativity using quantum mechanics, overcomes this tremendous pull and liberates everything shown in the top half of the image, thus solving the fundamental problem of black hole singularity.

When stars collapse, they can create black holes, which are everywhere throughout the universe and therefore important to be studied. Black holes are mysterious objects with an outer edge called an event horizon, which traps everything including light. Einstein’s theory of general relativity predicted that once an object falls inside an event horizon, it ends up at the center of the black hole called a singularity where it is completely crushed. At this point of singularity, gravitational attraction is infinite and all known laws of physics break down including Einstein’s theory. Theoretical physicists have been questioning if singularities really exist through complex mathematical equations over the past several decades with little success until now. LSU Department of Physics & Astronomy Associate Professor Parampreet Singh and collaborators LSU Postdoctoral Researcher Javier Olmedo and Abhay Ashtekar, the Eberly Professor of Physics at Penn State developed new mathematical equations that go beyond Einstein’s theory of general relativity overcoming its key limitation—the central singularity of black holes. This research was published recently in Physical Review Letters and Physical Review D and was highlighted by the editors of the American Physical Society.

Theoretical physicists developed a theory called loop quantum gravity in the 1990s that marries the laws of microscopic physics, or quantum mechanics, with gravity, which explains the dynamics of space and time. Ashtekar, Olmedos, and Singh’s new equations describe black holes in loop quantum gravity and showed that black hole singularity does not exist.

“In Einstein’s theory, space-time is a fabric that can be divided as small as we want. This is essentially the cause of the singularity where the gravitational field becomes infinite. In loop quantum gravity, the fabric of space-time has a tile-like structure, which cannot be divided beyond the smallest tile. My colleagues and I have shown that this is the case inside black holes and therefore there is no singularity,” Singh said.

Instead of singularity, loop quantum gravity predicts a funnel to another branch of space-time.

“These tile-like units of geometry—called ‘quantum excitations’— which resolve the singularity problem are orders of magnitude smaller than we can detect with today’s technology, but we have precise mathematical equations that predict their behavior,” said Ashtekar, who is one of the founding fathers of loop quantum gravity.

“At LSU, we have been developing state-of-the-art computational techniques to extract physical consequences of these physical equations using supercomputers, bringing us closer to reliably test quantum gravity,” Singh said.

Einstein’s theory fails not only at the center of the black holes but also to explain how the universe was created from the Big Bang singularity. Therefore, a decade ago, Ashtekar, Singh, and collaborators began to extend physics beyond the Big Bang and make new predictions using loop quantum gravity. Using the mathematical equations and computational techniques of loop quantum gravity, they showed that the Big Bang is replaced by the “Big Bounce.” But, the problem of overcoming black hole singularity is exceptionally complex.

“The fate of black holes in a quantum theory of gravity is, in my view, the most important problem in theoretical physics,” said Jorge Pullin, the Horace Hearne professor of theoretical physics at LSU, who was not part of this study.

The research was supported by the U.S. National Science Foundation, the Urania Stott Fund of the Pittsburgh Foundation, the Penn State Eberly College of Science, and the Ministry of Economy and Competitiveness, or MINECO, in Spain.

    If v>=10c,then we can pass the black hole.

  2. Science achieved many breakthroughs this year, first the Riemann hypothesis, then the artificial sun made by China and now about this quantum loop gravity. This truly proves that nothing is impossible…

  3. In my childhood I learned about heaven and hell which are outside our realm. Now I learn about “another branch of the space-time”. It seems that some physicists publish their visions similarly to biblical prophets. Star Trek movies had shown how people can travel faster than light. Did they show how to switch to a parallel Universe?

  4. Helpful article on singularity, space time and gravity. I especially like your adding a link to the original article.
    Following are some of my thoughts on the matter. According to current theory, small pieces of randomly moving matter in space attract each other with their individual minuscule gravitational fields and thereby eventually form increasing larger amounts of matter, eventually leading to stars and planets. The high concentrations of matter warp nearby space-time and create a gravity effect.

    The Einstein field equations EFE describe the fundamental interaction of gravitation as a result of spacetime being curved by matter and energy. A re-interpretation of the EFE could lead to the following alternative explanation of how matter collects to form planets and stars, and how spacetime is warped by matter. Rather than matter first collecting, and then distorting space-time and thereby creating gravity effect, I hypothesize  that discontinuous areas of SpaceTime could result in concentrated areas of gravity which then attract collections of matter. In a way, this is a reversal of the classic chicken (matter) or the egg (gravity) argument.

  5. @Donald Marks: Amazing idea! The answer to the chicken, egg question would be a link between Einstein general relativity and Standard Model

    P.S unless the existence of the question itself is already the link… 🙂

      Perihelion Shift of Mercury (essay)

      Mercury is revolving in orbit. Size of Mercury increases centrifugal force acting on revolving Mercury. This will be reason for perihelion shift of Mercury. The angle is about 5.75 arc-sec in a year.

      Size of Mercury will also increase gravity of Sun (which acts on Mercury). But it will not affect direction of long axis of elliptical orbit (after a round: that is, it will be unrelated to perihelion problem).

  6. @Donald Marks: [brainstorming idea] imagine that this primal energy points is pushed towards or away from each other through the ripples caused by those more dense areas of matter/energy which drives us into a conclusion what are those ripples made of? Highs Field 2.0 :). Interesting thought.

    Does anti-singularity combine with non-locality (re: I think Bell) to demonstrate a multitude, perhaps observably preceding the appearance of a space-time singularity?

    Great article!
    It seems there will never be a fully established universal theory or law after all; a new discovery will always be made, one that will disprove and extend a previously held one (no matter how reverential we may uphold the latter, or how great the postulator may be-Enstein, Newton,etc.) Einstein’s General Relativity predicts the existence of a singularity at the centre of a black hole, now this Loop Quantum Gravity theory disproves that; Newtonian Mechanics assumes a universal time frame, and Einstein’s theory says there’s no such a thing as that.
    One theory says something and a new, more robust one comes along that paints quite a different, more general picture.
    This is the nature of Physics, and Science in general. Knowledge grows, and previously held theories crumble in wake of new ones. The search for an ultimate theory of the universe will forever be elusive!

    If one takes into account the axial Doppler shift, there is additional dimensions for time perceived by and observer of a moving object (proper time). Because there is the angle of observation in the axial Doppler shift (angle between a line from the observer to the observed and the motion). Multi-dimension time kills General relativity. For a discussion of this go to this link:https://drive.google.com/open?id=1ERT2iqUtpfn7SXUCJAqZ9_UOe4mv1WOT

  14. If there’s no singularity then the density wont be infinite and subsequently the energy emitted by it wont be infinite too.. so by Einstein’s theory their gravitational pull would be less than that actually predicted wont it?

  15. Albert Einstein was wrong about the speed of light for which that was just his perception through a vacuum. Therefore, the speed of light is infinite in my opinion.

  16. General Theory of, not Theory of General. The theory is general, not the relativity.

  17. Math is nothing more than a linguistic metaphor, a map for describing our experiences. We must remember that the map is not the territory. Math is a linear system, and there are no strait lines in reality, just circles and spirals. Can math accurately describe these? NO!
    PI=3.141592654… :it can not be written down!
    PHI=1.618…. :it can not be written down!
    We can use math to a precision that works for describing OUR EXPERIENCES. That does not mean it is the translation of reality.
    IF people could finally find the “Universal Equation” that completely describes the universe, bringing together all the equations that they have to describe all the phenomenon in the Universe (an unrealistic expectation of “God” by my guess) they will find that the Buddha described it years ago in another language, and the Vedas before that. In math it is:
    (1=0=∞) (one=zero=infinity: we each are are nothing yet everything)
    When theoretical physicists factor in the findings of Cognitive Science they will begin to understand that.
    Or at least that is what came to me while meditating.

      Send me more details of it

      • I read George Lakoff ([was/is?] professor of Linguistics at the University of California, Berkley): “Women, Fire, and Dangerous Things: What Categories Reveal about the Mind”; but, with Mark Johnson, “Metaphors We Live By” may better express the Cognitive Science foundation of what I am trying to convey.
        There are only a handful of “base metaphors” on which all other metaphors are based, and all language is based on metaphors. These “base” metaphors are something like “in/out,” “up/down,” etc…
        Their theory is NOT that “Math can not be a universal language based on a reality that our bodies have evolved to comprehend,” (as I remember the Gnostic teachings to be that Math is God’s language that we are held to learn, if my history holds) but rather that “we understand Math in terms of our basic Embodied Mind’s perceptions, and therefore our comprehension of systems that don’t adhere to those perceptions (quantum physics) falls apart”.
        What does it mean for light to be a wave of energy and a particle at the same time? That is the translation of the Mathematical language through our natural linguistic metaphorical system into our perceptual comprehension. That only means WE CAN NOT ACTUALLY COMPREHEND THE MATH in terms of our Embodied Mind.
        The limits to this Embodied Mind may very well be unknowable to us. Therefore we come up with equations that seem to work, but when they are all added together, they simplify to 1=0=∞
        Or something like that, if I understand their proposition.

      • In other words:
        There MAY be some aspect of the Universe that we *can*not* comprehend because it will not fit into the categories of our perceptions; therefore we can not create a mathematical equation (linguistical expression) for it, and therefore our sum-of-equations becomes 1=0=∞. However, even that statement is misleading, because “aspect” is a metaphor based on the “parts” metaphor based on the “thing” metaphor which is rooted in our handful (pun intended) of Base Metaphors of the Embodied Mind; since we can understand “things” and “parts” therefore “aspects”, we could then ultimately understand what is is I am saying we can not.
        So we are stuck in a linguistical conundrum, and Math is very rooted in those same Base Metaphors of the Embodied Mind.
        Many call that “aspect” the “spiritual dimension”; but that uses words and therefore metaphors that we can understand.
        Taoist say that the Tao that can be spoken of is no the Tao.
        Somewheres in the Christian Bible it says God has no “name” other than “God” because naming “God” limits “him” to a metaphor, which is comprehend-able to us.
        Other “religions” say “God” has so many, many names (or in Hindu there are many Gods which are all part of the greater One), again because limiting “him” to a single metaphor is misleading us in to thinking we can ultimately comprehend “him”.

      • Finally, I ask, and subtly suggest in these comments, does the Embodied Mind and its natural ability to comprehend Math yield Meditational Experiences of Oneness with the Universe combined with the understanding that ultimately we are nothing in the face of everything, yet we are that everything? 1=0=∞

  18. The speed of light is not infinite, if it was your eyes couldn’t see colors, each color is a fixed speed that your retina and brain understand.Einstein is still right.

  19. Just as Eisteins theory took us beyond Newtons understanding. New theories like this will take us beyond Einsteins. It’s an exciting time with the competing theories about time, space and other dimensions.

  20. @Lynx: I gotchu, bro

  21. My bs meter has hit the speed of infinity my attention tubes have melted and above all else the price of eggs in China has remained the same as yesterday.

  22. @Lynx – yup!

  23. Einstein’e relativity is a wrong theory. There is nothing called spacetime in nature, not to mention the existence of black holes as singularities of spacetime. All the theories based on relativistic spacetime model are wrong. The fatal mistake of Einstein’s relativity is that it uses Lorentz Transformation to redefine time and space and the newly defined time is no longer the physical time we measure with physical clocks. We know the physical time shown on any physical clock is T = tf/k where t is the theoretical time, f is the frequency of the clock and k is a reference frame independent calibration constant. In Newton’s mechanics, f is a reference frame independent constant too. Therefore, we can set k = f to make the clock show the theoretical time i.e. the absolute Galilean time: T = tf/k = tf/f = t.

    But in special relativity, frequency is a reference frame dependent variable and can’t be eliminated by setting k = f, thus, T can never be relativistic time t: T = tf/k != t. Therefore, relativistic time is never the clock time i.e. the physical time. On the other hand, when a clock is observed in another inertial reference frame, t’ = γt and f’ = f/γ and T’ = t’f’/k = γt(f/γ)/k = ft/k = T, which means that clock time won’t change with the change of the inertial reference frame, Lorentz invariant and absolute. That is, a clock still measures the absolute time in special relativity. As relativistic time is not the physical time we measure with physical clocks, special relativity is wrong.

    The fact that physical time (i.e. clock time) is absolute has been clearly demonstrated by the clocks on the GPS satellites which are synchronized not only relative to the ground clocks but also relative to each other, directly denies the claim of special relativity that clocks can never be synchronized relative to more than one inertial reference frame no matter how you correct them.

    Besides the instruction as cause for everything imminent in existence, a function of polarity as (residual) provisional augmentations of space, light was created with space at its boundaries. The structures and compositions of matter upon their creation are derived from the atomic and subatomic plenums, expressed as sine derivation with (timed-tined-polarity, two time grids – one next to one) polarity’s (spin to tine time) all collective arrangements of these tiny constituents (polarity’s sines to twine-time) for motions of all mechanical macroscopic facts.

    Equivalence principle

    On a plain, imagine two gravity sources and fine circular waves (gravity). On every point, vector of two gravity acts as a resultant force and there is a point where the resultant force disappears. Next, gravity source is one. Huge elevator cabin is in free fall. Fortunately, this elevator is empty. So, resultant force of gravity and inertial force that acts on every point of the structure does not disappear.

    Let’s start from accelerated motion. Many substances (solids, fluids, etc) are moving in various accelerated motion. According to this motion, inertial force occurs. Imagine water of a current. Involvement between inertial force and gravity will be on resultant force only.《P.S.》Acceleration is not relative and inertial force is not fictitious. The two are corresponding qualitatively and quantitatively.

    Free fall of an elevator will be (one of the) problems of resultant force (composition of forces). All will be explicable as a problem of resultant force.

    There are two pictures. In each picture, vector of two forces (f = f’) acting on a point are drawn. Direction of vectors is opposite (right and left). In one picture, forces are gravity and gravity. In the other picture, gravity and inertial force. Two pictures will not be the same (an infinite small area will be also).

  28. Science will never be able to find out and understand many phenomena in the universe because it does not know the basis of the universe. First of all, no one knows what is matter, how and from what forms and how gravity and magnetism originate and who causes them. Besides this, science did not understand the sequence of formation and processes of the origin and disappearance of celestial bodies. Black holes are not the result of a star explosion. They are created under the influence of gravity, when in a given system, it accumulates so much mass that it represents a critical mass and critical gravity, when the matter returns to the form of the substance from which it was formed, and that substance is Aether that fills the infinite universe. Einstein’s Fatamagoras have been entangled in science, and to this day, many theories are unsurpassed and have no foothold in natural laws.

    Why This Equation Is Incomplete One?
    The matter is created in motion (my hypothesis)
    That means without motion the matter will be perished –
    The motion here means the matter outer motion – as the moon motion around Earth- and I don’t mean the atoms motion inside the matter-
    So
    The Matter is created with the space because the space is the necessary component for the matter motion-
    That means
    The matter and space are created from the same origin to be complementary to each other
    That’s why the previous Equation is incomplete one
    ETotal = EMass + ESpace
    So
    ETotal = mc2 + ESpace
    This is The complete Equation

    A passenger car is accelerating (at a, to the right). A body is hung from the roof by a string. Can the string distinguish mg caused by acceleration and by gravity ? No, it is a joke. But a picture of an elevator seems to be a joke also.

  39. Accelerated motion
    Accelerated motion will be the motion relative to aether frame. Vector causes the same vector of inertial force. Gravity has no connection.

    From every inertial frame, accelerated motion is possible to know qualitatively and quantitatively.

    Perihelion shift of Mercury

    There is a model of Mercury. A long lod penetrates a true sphere and at the both ends of the lod, weights are set. This model is rotating horizontally and is moving on the orbit of Mercury (two planes fall on). Main forces acting on the weights are gravity of the sun and inertial force (centrifugal force). And each force acting on the outside weight and inside weight is different.

    Inertial force pulls the orbit to the outside. But actual orbit of Mercury is pulled to the inside. Gravity of the sun acting on the two weights is inversely proportional to the square of the distance (not come out even. not plus minus zero). In Mercury, the action of gravity will be superior.

    Mercury is moving on the revolution orbit. The sun’s gravity is equal to the centrifugal force. Because the two are action and reaction. Following are some explanations. Centrifugal force follows Mercury’s mass. But in addition, gravity is affected by the size of Mercury (and acting position of gravity is different). These are caused by the non-uniformity of gravity (in the space occupied by Mercury). And after perihelion passage, orbit will be pulled inward (from its original orbit).

    High tide level twice a day is the same. Gravity and centrifugal force caused by the moon will be action and reaction. Centrifugal force is not fictitious.

The bulge is symmetrical. Two resultant forces pull two bulges (to the opposite direction : outward). Two resultant forces each are composed of the lunar attractive force and the centrifugal force caused by earth’s orbital motion (moves around the common center of gravity with the moon). Two resultant forces will be equal strength. This will explain that the level of high tides twice a day are generally the same.

    Also, the lunar attractive force acting on the earth’s center of gravity (not the center of mass) and the centrifugal force resulting from its orbital motion (mentioned above) will be action-reaction and will be equal.

    Suppose the moon and the earth is two-body problem. And imagine, the earth is revolving (not rotating) around the common center of gravity with the moon. The orbit is a perfect circle. If lunar attractive force acting on the center of gravity of the earth is action, the centrifugal force of the earth is a reaction. And the strength of the two will be equal. This will be also true for the earth as a whole.

    In an illustration, the earth is drawn next to moon. Imagine two points on the surface of the earth closest to the moon and farthest from the moon. The difference between lunar attractive force and the centrifugal force of the earth at above two points will be almost equal and therefore the resultant force will also be almost equal. This will explain that the level of high tides twice a day are almost equal.

    A celestial body called Vulcan is revolving on orbit of Mercury. It has the same mass and revolution cycle as Mercury. And diameter is twohold (the both stars are uniform in density). Since the sun’s gravitational field is non-uniform, the sun’s gravity acting on both stars will be slightly larger in Vulcan and smaller in Mercury. The value of perihelion shift also likely will be similar. In short, the size of the celestial body (close to the gravitational source like Mercury) will be the main reason for the perihelion shift.

Number of waves hitting the front and rear ends (A and B) of each spacecraft is the same. Therefore, number of waves existing between A and B is invariant (for both spacecrafts, regardless of lateral motion). Lorentz contractions will be impossible.

    Free fall (an essay)
    Rewriting of my past post (Sep 6 2021)

    An elevator cabin is falling in free fall. Cabin is made up of n mass points (with the same mass of m). Imagine a single moment of falling.

    Inertial force acting on each mass point is the same ma. No exceptions. On the other hand, magnitude of gravity acting on each mass point is not the same slightly. Difference depends on the position of the mass point.
    P.S. For the entire cabin, magnitude of inertial force and gravity is equal.

    Speed of light (an essay)

    The defined value of speed of light is based on measurements (with wavelength and frequency) done by Evenson et al. in 1973. Error is 1.1 m / s in pramai. Now measuring instrument is separated into a measuring part and a light source part. When one of them is moved at a constant speed higher than above error (in the direction of light path), different value will be obtained.

    About light (re-post)

    ◎ How are light waves propagated ?
    1) Emission theory (for a few seconds only)
    2) On aether (after the above)
    ◎ How are light sources visible ?
    1) For celestial bodies beyond a few light-years, effect of emission theory is too small to be found (e.g. binary stars). So, every celestial body is visible to be stationary on aether (celestial sphere). Also by various aberrations.
    2) Moon is by emission theory.
    3) Celestial bodies in solar system (excluding moon) are depending on planetary aberrations. Also, depending on other aberrations (but, is secular aberration offset ?).
    ◎ Motion of light seen by observers
    Same as bodies. Follows Galilean transformation. Constancy of speed of light cannot be hypothesized. By the way, light waves (speed = fλ) and photons (rays) are basically different. Especially in outer space.

    Perihelion shift of Mercury is about 574 arcsec per century, and main cause is said to be perturbations due to the gravity of other planets (Venus is about 280 arcsec, Jupiter is about 150 arcsec).

    There is a question. At the left end and the right end of the orbit of Mercury (a view from above), force that accelerates and decelerates Mercury by perturbation by other planets will be equal (in probability). Especially in the span of the century. Main cause will not be gravity of other planets.

    Note: Here is a horizontal line. From the right, gravity of main star is acting. On the line, we see three masses. Mass of right and left is m/2 and middle is m (interval is the same). Magnitude of gravity acting will be m<m/2+m/2.

Newton whispers that reaction of the third law can include inertial force. And that, there are other pictures of equilibrium of forces including inertial force.

    Not a few books and websites say that the third law is the law of two bodies. Newton’s original text is neglected. No, third law is the law of at a point of action of force. A piller of mass m is lying on a horizontal plane (without friction). If the piller is continuously pulled to the right, it is accelerated to the right. At the right end of the piller, magnitude of action-reaction is the same ma. Also, at the other positions (points of action) of the piller, magnitude of action-reaction is the same.

On Mercury, these have effect on gravity and it will be the first cause. And then, direction of elliptical orbit may be shifted. At perihelion, this effect will be greatest.

    Magnitude of perihelion shift of planets with satellite is far superior. This is probably because gravity of Sun acting on satellite in half orbit close to Sun is far superior.

    Starting is to accept inertial forces as inertial forces. In a free-fall elevator, inertial force and gravity acting on the entire cabin is equal. As Newton’s third law of motion shows.

    A body is suspended by a string from roof of a passengercar. The same two passengercars started at the same jerk at the same time.

    Assume that sun’s light follows emission theory for a few seconds only. Matter of those on few seconds will be indistinguishable from earth. That is, sun is being in aether. So, light-time correction. And, light-time correction will be offset by secular aberration.

    In a book Theory of Relativity by Pauli, W 1958, it’s written as follows (quoted from English version ; in 1-6). “Rather should one say that for an observer moving with medium, light is propagated as usual with velocity c/n in all directions”. It seems to be the “very and true explanation” for M-M experiment (done in air) !!

    There is Einstein’s saying the same as above Pauli’s. Therefore, probably, he said that he didn’t know M-M experiment (and he mutters, “It is (done in air) is nonsense and I have no obligation to talk about it”).

    In the elevator, equal acceleration due to falling is acting on every mass point. There are no exceptions. Even locally.

    There can be composition or partial composition of inertial force and gravity. But the two are inviolable to each other. Inviolable, qualitatively and quantitatively.

    Absolute Rest Frame

    Newton’s Bucket” is a thought experiment that assumes the existence of absolute rest frame because of the rotational motion accompanied by inertial forces. Let’s take the thought experiment one step further. Inertial force must occur by “all motions except uniform linear motion” of a body with respect to absolute rest frame. Without exception. And inertial force is real existence in physics.
    Note: Uniform linear motion and other motions can be superposed. And, superposition is very universal.

This is probably due to absolute rest frame. Aether frame and absolute rest frame each will probably be one and only, homogeneous, isotropic. And perhaps the two are the same frame.

It will be certain that observer’s motion (in the light ray direction) does not affect anything of coming ray (intermittency, wavelength, amplitude, waveform, etc).

    In outer space, a starlight is coming. When an observer moves in the direction of light path, frequency varies. But, according to this, in the formula c = f λ, does wavelength λ vary ? Unbelievable !

    There is a word “wavenumber”. It is the number of waves in a unit length (1 cm or 1 m) and is called Kayser. Like 25,000 K (visible red). This wavenumber and wavelength are reciprocals of each other. Therefore, since the wavenumber is an invariant, the wavelength will also be an invariant. That is, the wavelength cannot be varied with the motion of an observer. It is the speed of light that varies.

    When a mass point is accelerated, inertial force appears. Its vector can be at our will.

    About the speed of light

    As for speed of light, constancy of speed of light, and the formula c = f λ seem to be all. But is it so simple ?

    A ray of light is propagating through aether. An observer is moving in a uniform linear motion lerative to this ray at various angle. The speed of the observer relative to aether is also varies. And, the observer’s motion can be accelerated motion, jerk (on a straight line), or can be curvilinear motion. Besides, there will be areas where the propagation of light follows emission theory.

    In short, there will be no reason to treat light specially. It’s so simple.

  202. About the Speed of Light

    For light that is propagated in aether, speed of light waves and ray (photons) relative to an observer will be different (usually). And, for light that is propagated according to emission theory, above will be the same (different also, usually).

    Annual aberration of Mars is based on its revolution period of 1.881 years and average orbital speed of 28.07 km/sec. That is, aberration is mainly caused by motion of observer relative to the aether. Qualitatively and quantitatively. Needless to explain.

    Other aberrations of Mars are also.

    Aether

    In outer space, three pinhole cameras are pointed in X, Y and Z directions (these are in uniform linear motion, the same as Sun). Cameras are pretty large. In the camera, on the inner wall, on the opposite side of the pinhole, disks rotate once and receiving position of star lights are recorded.

    Recorded position of star lights on three disks will not be true circle. These may indicate motion of the pinhole cameras relative to aether.

    Pinhole Camera

    In outer space, a starlight is coming from the right. This ray enters the pinhole of a pinhole camera and is reflected upward by a mirror set at 45 degrees upwards in the camera.

    When the camera moves to the right or left (at a uniform speed), the position where reflected light hits the upper inner wall of the camera will move. Incident light is propagated in aether, and reflected light follows emission theory.

    Note: Speed of lincident light and rleflected light relative to the mirror are generally different. So, angle of the two are also. λ are also).

    Speed of Light Varies

    On the Moon’s surface, plane waves of Sunlight are arriving horizontally from above to two passenger cars. There is a small pinhole at the center of ceiling of two passenger cars, and on the floor, there is a spot of light that passed through pinhole.

    Two passenger cars are moving on the Moon’s surface at different speeds (in x direction). For an observer inside the passenger car, position of light spot on the floor will be different. This difference in position will be the same for an observer stands on the Moon’s surface.

    Two Formulas for Speed of Light (in vacuum)

    First formula, v=fλ: It is speed of light relative to aether, and v is constant. Area is where light follows aether frame. That is, more than a few light seconds away from light source.
    Second formula, c=fλ; It is speed of light relative to light source, and c is constant. Area is where light follows emission theory. That is, within a few light seconds from light source.

    Note) First formula is the same as formula for the speed of sound in air (depending on f and λ).
    Note) In outer space, a starlight is passing through a tube. In the center of the tube, a plate of glass is placed. In front of the glass, the starlight follows aether frame, and in back of it, starlight follows emission theory.
    Note) A starlight is moving in aether. It is possible that v and c move at the same speed. Usually, v will be below c.
    Note) For a moving observer, speed of light must be reconsidered (starting with the Doppler effect).

    Speed of Gravity Propagation

    Speed of gravity propagation is said to be the same to speed of light. But is it true ? Something can’t be found in thought experiments ? How about Sun and Mercury ? Solar system is said to move in the direction called sun facing point (on the celestial sphere). So position from which gravitational force of Sun acting Mercury will be the position some back in time. If so, this effect will slightly acuumlate (like free falling).

    Perihelion Shift of Mercury (rewritten)

    In a figure, Mercury is drown as a circle. In addition, in the figure, center of the circle and an arc extending vertically through the center are drown. Arc is a part of orbit. The arc divides Mercury into left and right, and the area is left > right (Sun is in the right). This figure shows that actual magnitude of the centrifugal force exceeds magnitude calculated for Mercury as a point (see formula of centrifugal force, ignore rotation). Perihelion shift of Mercury may be due to Mercury’s size.

  263. Perihelion Shift of Mercury

    Size of Mercury will increase gravity and increase centrifugal force quolitatively also. Of the two, gravity is probably the main factor. Because, increase in gravity shift aphelion in the direction of revolution. On the other hand, increase in centrifugal force shift aphelion in the opposite direction of revolution.

    The formula for gravity F = mM/r^2 probably shows that magnitude of gravity is related to the size of Mercury (but surprisingly small).

  264. Perihelion Shift of Mercury

    [Size of Mercury increases gravity during orbital motion]
    Mm/r^2 is formula for gravity. There are models for Mercury and Sun. When, 2Mm is 100 and r is 50, gravity is 0.04. Next, two spheres (with half of mass of Mercury each) are lined up on the line of action of Sun’s gravity. Mm is 50, r is 49 and 51. Then, gravity is 0.0400479.
    [Size of Mercury increases centrifugal force during orbital motion]
    See my post posted on March 15, 2023 (or around).

  265. Perihelion Shift of Mercury

    There is one more problem. Size of Mercury send out surplus force. But where does this surplus force go ?

    In figure of perihelion shift of Mercury, its destination seems not to be found. Ah, perhaps the same phenomenon as Moon’s retreat (Moon’s orbit is expanding) will be destination. This surplus force probably turns and expands Mercury’s elliptical orbit each time.

  266. Perihelion Shift of Mercury (rewritten, from my post, posted on Sep 16 or around)

    There is a figure of Mercury, its orbit and Sun. Mercury is drawn as a single point. But actually, Mercury has a size, and this size will slightly increase magnitude of gravity and centrifugal force of Mercury. Now, limit our consideration to half of orbit from perihelion to aphelion. Increase in gravity will shift aphelion in the direction of revolution. On the other hand, increase in centrifugal force will shift aphelion in the opposite direction of revolution. In increase, gravity will exceed.

  267. Perihelion Shift of Mercury (supplement)

    Size of Mercury will cause the difference in its gravity and in its orbit. It will rotate long axis and shift perihelion (in the direction of revolution).

    But, will size of Mercury cause difference in its centrifugal force ? This difference probably correspond to the difference in motion (caused by difference in gravity).
    Note) How does gravity cause bodies to move ? In phenomenon such as perihelion shift of Mercury, we seem not to grasp it enough.

  268. Perihelion Shift of Mercury (imagine)

    Size of Mercury will increase Mercury’s gravity. The main result will be slight expansion of orbit, and followed by shift in perihelion. Therefore, centrifugal force also increases. Newton’s third law of motion will be inviolable.

    Towards Earth, two bodies with the same mass are in free fall. One is assumed to be a single point (with no size), and the other is a long pole (falling vertically). Also assumed that gravity of Earth is constant at g. As posted formerly, magnitude of gravity of Earth acting on two bodies will be former < latter slightly. As example, in my former post, it was 0.04 < 0.0400479. So latter continues to fall in advance. In a broad sense, orbital motion is considered to be free fall. It seems that the shift of perihelion of Mercury is caused by its size.

Shift of vernal equinox is said to be caused by precession of rotation axis (of Earth). Precession of rotation axis ? Really ? Shift of vernal equinox seems to be caused by extra centrifugal force due to size of the Earth. There is no other reason than that it seems to fit well.

    Perihelion Shift of Mercury (summary)

    In a web-site in English titled “Perihelion Precession of the Planets”, there is a table on observed rates from Mercury (5.75 seconds/year) to Neptune (0.36 seconds/year). In these, direction of precession is the direction of planet’s revolution, and these magnitude are assumed to be constant. Let’s assume this table is true. So, this phenomenon will be caused by two bodies: planet each and Sun.

    Adams and Le Verrier predicted the existence of Neptune and its position on the celestial sphere (from the precession of Uranus’s position). But it was temporary and exceptional precession (perturbation).

This will lead to zero inertial force in non-accelerated motion. Without exception. In addition, let us assume that non-accelerating motion includes absolute rest.

    Measuring Aether (again)

    In outer space, frequency and wavelength of incoming lights from two stars (from opposite directions on the celestial sphere) are measured. To the measurer, speed of two incoming lights will be different. And sum of speed of two lights will be 2c (or close to 2c : constant). In post March 5, 2024, it is forgotten to note. Sorry.

    Accelerated Motion & Inertial Force (again)

    Accelerated motion is absolute motion relative to aether frame. The two are two sides of the same coin. Gravity is irrelevant at all, and does not play a role in this problem.

    Accelerated Motion (again)

    A passenger car is accelerating to the right (uniform acceleration). A light source (wavelength is onstant) at the rear wall of the car emits light, and on the front wall, frequency measuring device is settled. During acceleration, in the car, there will be more waves than before. In other words, accelerated motion is not fictitious (inertial force will not be fictitious also).

    A ray of light is emitted from the ceiling of a passenger car directly below. When this car is accelerated, the light ray reaches the floor in a parabola. Difference between acceleration and non-acceleration is not fictitious.

    Local Inertial Frame (again)

    An elevator cabin is in free fall. Imagine mass points placed regularly in the elevator. Vector of inertial force acting on each mass point is the same. Local inertial frame is impossible.

    Two elevators are moving apart horizontally. One is in accelerated motion and the other is in non-accelerated motion. By an accelerometer, to tell which one is accelerating is possible. In the elevator with accelerated motion, there is no inertial frame, even locally.

    Accelerated Motion and Non-Accelerated Motion (again)

    Difference between the two motions above will be the difference of motion with respect to aether frame. A mass point moving in accelerated motion is accompanied by inertial force, that corresponds qualitatively and quantitatively. A mass point moving in non-accelerated motion (uniform linear motion) is not accompanied by inertial force.

    A saying are trying about inertial force and gravity. What can we say by comparing the two words ? Inertial force is inertial force, gravity is gravity and both are true forces ! That seems to be all that can be said. This is a short report.

    Equivalence Principle (again)

    On the ground, a passenger car is moving with uniform acceleration to the right. In the car, a body hanging from the ceiling with a string is swinging to the left. The angle can be explained qualitatively and quantitatively using equations based on Newton’s laws of motion. What about equivalence principle ? Is there anyone who can ?

    Equivalence Principle (again)

    Allow me to repeat the previous question,regarding two situations ◎ below. Two situations ◎ can be explainend qualitatively and quantitatively using formulas based on Newton’s laws of motion. The question is, how to explain equivalent principle ? Is there anyone who can ? .
    ◎ Forces of the same magnitude are acting on a mass point from the left and right directions. Types of forces are tension, gravity, and inertial force. Since there are no combinations of inertial forces and inertial forces, there are five combinations of forces (ignoring the difference between left and right).
    ◎ A body is sliding down inclined surface (no friction).

    Accelerated Motion and Non-Accelerated Motion (again)

    All accelerated motion is accompanied by inertial force (it is reaction. See Newton’s third law of motion).

    All non-accelerated motion is not accompanied by inertial force. It is the same for absolute rest (relative to aether frame).

    Gravity is unrelated to this problem.

    Law of Universal Gravitation (rewritten)

    Formula for the law of universal gravitation is F=GMm/r^2. Value r is the distance between centers of gravity of the two bodies (let’s call them spheres L and R). If r is 50, the squared is 2500. It is the first diagram.

    Now, this is the second diagram. On a horizontal straight line, spheres L, R1, and R2 are lined up. If distance between L and R1 is 49, and distance between L and R2 is 51, the squared are 2401 and 2601. If these two are added and divided by 2, the value 2501 is gotten, which is slightly larger than 2500. In other words, the formula of universal gravitation doesn’t care about the size of the two sources of gravity, but in reality, there will be some effect, even if it’s a little ? Is Newton’s spherical shell theorem not perfect ? Is this the main cause of apsidal precession ?
    Note) 2500 and 2501 are coefficients in numerator of the formula.
    Note) Masses of R1 and R2 each are 1/2 of the mass of R.
    Note) Assume that R1 and R2 are hemispheres of R (distance of centers of gravity is 2).

    Lunar Laser Ranging (again)

    Distance between Moon and Earth is measured with millimeter precision. Measurement is based on the formula “distance = speed of light x round trip time / 2”. What is noteworthy here is that the direction of laser beam with respect to celestial sphere does not affect the measurement results.

    Assume that the space where Moon and Earth exist is also filled with aether. Measurement results will differ depending on the direction of laser beam with respect to celestial sphere (according to the explanation of MM experiment).

    However, aether does not affect the propagation of electromagnetic waves at the distance between Moon and Earth. That is, aether does not affect the propagation of electromagnetic waves for a few seconds after emission. Ritz’s emission theory is revived, although in a limited extent. For now, let’s take this as an assumption. There is no need to be worried about the framework of time or space.

    One-way Speed of Light/Isotropy of Aether (again)

    English version of Wikipedia has an item titled “One-way speed of light”. Word isotropic is found in 27 places.

    However, if the light from multiple celestial bodies on the celestial sphere is recorded and analyzed in outer space, one-way speed of light will become disclosed. Probably easily. By established means of measuring aberration.

    The position of bright lines and dark lines in spectrum of the celestial body’s light will show the speed of celestial body’s light and speed of light relative to Earth (and Aether drift). The isotropy and uniformity of aether will also be disclosed.

    Aether Drift (again)

    Speed of light is the distance that light travels in one second, 299,792,458 m/s (defined value). Above value was obtained by measuring frequency and wavelength of laser light that is performed by Evenson et al in 1973 (error was ± 1.2 m/s).

    Imagine frequency and wavelength of light coming from two fixed stars located at symmetrical points (at opposite ponts) on the celestial sphere. Measuring must be done simultaneously. Perhaps many of the measured speeds of light are different. If so, it will be possible to identify two points (on the celestial sphere) where the difference is greatest.
    Note) Differences due to known mtion of Earth such as revolution and rotation must be excluded.

    Hollow Tube and Speed of Light (again)

    In outer space, starlight coming from the left is passing through a stationary horizontal tube of length L. Frequency at the left and right ends of the tube is the same. This sameness is true even if the tube is moving in the left and right directions at different uniform speed. In other words, number of waves that exist inside the tube (wave number × L) is invariable. There is no varying in wavelength of light. In the formula, c = f λ, it is f and c that vary. It is the first picture.

    In the second picture, there are two tubes the same as above. The two are moving at a uniform speed. One is to the left and the other is to the right. As mentioned above, wavelength of light is the same. In the formula, c = f λ, f and c (of the two) are not the same.

    Wavelength Measurement (Aw)

    Is wavelength of light traveling in outer space being measured as it is (on light before arriving) ? Isn’t what is being measured light (extincted light) that has passed through a medium such as glass ? In internet (a bit), any site mentioned can not be found.

    Suppose an observer moving in various motions in outer space is measuring wavelength of starlights. In the formula, c = f λ, f varies. Accordingly, c varies. However, we seem to believe, it is λ that varies.

    We must distinguish the light before and after measurement device (before and after extinction).

    Wavelength Measurement (supplement)

    A starlight is passing through horizontal tube in outer space from left to right. A flat glass plate is fitted in center of the tube. Imagine that this tube is moving at different uniform speed in left and right directions. For left and right light each, the formula v = f λ holds. Frome the perspective of the tube, f on the left and right sides are the same. But v will be different and λ will also be different.

    There is an argument that v are the same. If so, λ must also be the same. However, λ on the left does not follow (does not be affected by) the motion of the tube. But λ on the right follows (is affected by). This difference must not be forgotten.

    The wavelength of light and the speed of light each is not the same before and after extinction.
    Note) For glass, extinction is done in the distance of 0.0002 mm.

    Extinction

    Light entering glass from outer space has a speed of c/n relative to the glass. This equalisation in speed within the medium is called extinction, and is completed in a very small optical path length that differs depending on mediums. For glass, it is 0.0001 mm.

    Imagine that the glass moves in various uniform linear motions in outer space. The speed of light coming the glass and leaving the glass are not the same (from the perspective of the glass).

    Speed of Light is not Constant Always (again)

    From the left, a starlight is coming to a glass cube floating in outer space, and is leaving to the right. At the left and right end of the glass each, frequency of starlight is the same. Imagine that the glass is moving at various uniform speeds to the left and right. Then, v of light on the left and right will not be the same, and so will λ (the formula v = fλ is viewed from perspective of the glass).

    Value of Speed of Light (of starlight in outer space)

    Light of two stars coming from the left and right is passing through a glass cube. This cube is floating horizontally in outer space. Inside the glass, formula c/n = f λ holds on starlight. Four values are known.

    Two lights inside the glass are spectralized and the spectrum (distance between chosen atom or molecule A and B) is compared. The distance will be slightly different.
    Note) For light in outer space, formula v = f λ holds. And value f is the same as f for the glass (from perspective of the glass).
    Note) It seems that extinction does not conceal the difference of spectrum.

    Allow me to revise the first “Note” of my post (most recent). Sorry.

    Note) For light before it reaches the glass, formula v = f λ also holds (from perspective of the glass). And value f is the same as f for the glass.

    Measuring λ of Starlight

    How is λ of starlight measured ? One thing is certain. The λ before it enters measuring device is not be varied with the motion of measuring device. So, if measuring device is moved, it will become clear which λ was measured (which λ of starlight before extinction or after extinction).
