**Fragments of the interior of a proton have been shown by scientists from Mexico and Poland to exhibit maximum quantum entanglement. The discovery, already confronted with experimental data, allows us to suppose that in some respects the physics of the inside of a proton may have much in common not only with well-known thermodynamic phenomena, but even with the physics of… black holes.**

Various fragments of the inside of a proton must be maximally entangled with each other, otherwise theoretical predictions would not agree with the data collected in experiments, it was shown in European Physical Journal C. The theoretical model (which extends the original proposal by physicists Dimitri Kharzeev and Eugene Levin) makes it possible to suppose that, contrary to current belief, the physics operating inside protons may be related to such concepts as entropy or temperature, which in turn may relate it to such exotic objects as black holes. The authors of the discovery are Dr. Martin Hentschinski from the Universidad de las Americas Puebla in Mexico and Dr. Krzysztof Kutak from the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Cracow, Poland.

The Mexican-Polish theorists analyzed the situation in which electrons are fired at protons. When an incoming electron carrying a negative electric charge approaches a positively charged proton, it interacts with it electromagnetically and deflects its path. Electromagnetic interaction means that a photon has been exchanged between the electron and the proton. The stronger the interaction, the greater the change in momentum of the photon and therefore the shorter the associated electromagnetic wave.

“If a photon is ‘short’ enough to ‘fits’ inside a proton, it begins to ‘resolve’ details of its internal structure. The result of interacting with this sort of photon can be the decay of the proton into particles. We have shown that there is entanglement between the two situations. If the observation by the photon of the interior part of the proton leads to its decay into a number of particles, let’s say three, then the number of particles originating from the unobserved part of the proton is determined by the number of particles seen in the observed part of the proton,” explains Dr. Kutak.

We can speak of quantum entanglement of various quantum objects, if certain characteristics of the objects are related to each other in a particular way. The classical analogy of the phenomenon can be represented by the toss of a coin. Let’s assume that one object is one side of the coin, and the other object is its other side. When we flip a coin, there is the same probability that the coin will land heads or tails facing up. If it lands heads up, we know for sure that the other side is tails. We can then speak of maximum entanglement since the probability which determines the value of an object’s characteristic does not favor any possible value: we have a 50% chance of heads and the same for tails. A smaller than maximum entanglement occurs when the probability starts to favor one of the possible outcomes to a greater or lesser extent.

“Our study shows that the interior of a proton seen by a passing photon must be entangled with the unseen part in just this maximal manner, as suggested by Kharzeev and Levin. In practice, this means that we have no chance of predicting whether, due to interaction with the photon, the proton will decay into three, four, or any other number of particles,” explains Dr. Hentschinski.

The new theoretical predictions have already been verified. If entanglement inside the proton were not maximal, there would be discrepancies between theoretical calculations and the results of the H1 experiment at the HERA accelerator at the DESY center in Hamburg, where positrons (i.e. antiparticles of the electrons) were collided with protons until 2007. Such discrepancies were not observed.

The success of the Polish-Mexican tandem is due to the fact that the researchers managed to correctly identify the factors responsible for the maximum entanglement of the proton interior.

In the naive schoolbook view, the proton is a system of three elementary particles: two up quarks and one down quark. However, the strong interactions between these quarks, carried by gluons, can be so strong that they lead to the creation of virtual particle-antiparticle pairs. These can be not only pairs of virtual gluons (which are their own antiparticles), but also pairs made up of any quark and its corresponding antiparticle (even one as massive as charm). All this means that inside the proton, apart from three valence quarks, there are constantly ‘boiling’ seas of virtual gluons and virtual quarks and antiquarks.

“In earlier publications, physicists dealing with the subject assumed that the source of entanglement should be a sea of gluons. Later, attempts were made to show that quarks and antiquarks are the dominant source of entanglement, but even here the proposed methods of description did not stand the test of time. Meanwhile, according to our model, verified by confrontation with experimental data, the sea of virtual gluons is responsible for about 80% of the entanglement, while the sea of virtual quarks and antiquarks is responsible for the remaining 20%,” emphasizes Dr. Kutak.

Most recently, quantum physicists have been associating entropy with the state inside a proton. This is a quantity well known from classical thermodynamics, where it is used to measure the degree of disordered motion of particles in an analyzed system. It is assumed that when a system is disordered, it has high entropy, whereas an ordered system has low entropy. It has recently been shown that in the case of the proton, we can successfully talk about entanglement entropy. However, many physicists have considered the proton to be a pure quantum state in which one should not speak of entropy at all. The consistency of the Mexican-Polish model with experiment is a strong argument for the fact that the concept of entanglement inside the proton as proposed by Kharzeev and Levin has a point. Last but not least, since entanglement entropy is also related to concepts such as the surface area of black holes, the latest result opens an interesting field for further research.

Positive thinking is the solution of all the problems of the infinite universe.

The disectional analogy of a proton to black hole with respect to entropy-surface area relationship is good.Mention of charm quark or quark-gluon ratio in entanglement of photon energy is useful.But without any details of figure, fact or phenomena is true.The same logic is true for Hawkin’s formulae in real black hole problem.Likely,same logic holds for paradox.So,indeed no real measurement process has been suggested by theoritical formula.However theories justify their right places.Thanks to the authors.

Thoughts on entanglement

Quantum Entanglement is perhaps the strangest phenomenon in physics, when some small particles may communicate with each other instantly and over vast distances. How can that happen without violating the maximum speed in the universe, the speed of light?

The two ways physicists have used to answer this, that the particles contain hidden variables of unknown natures and that the universe is completely deterministic with all results predefined, have been shown to be incorrect.

Perhaps concepts in String Theory can help. There are 11 possible dimensions in String Theory and I suggest one of them leads a way around, what Einstein called this “spooky action at a distance”. Specifics can be found in my YouTube “Quantum Entanglement – A String Theory Way” at https://www.youtube.com/watch?v=L_pqTx_50E0

I’ve theorized for years at the center of every particle is a miniscule black hole. the pattern carries out to the universe which is a particle in another universe.

dont poke through the tiny black holes though, you may see it coming towards us from afar!

The proton can have an orbital or it can be stripped of an orbital, when a proton has orbitals the proton is balancing that which is pulled straight into infinity, through spherical coordinates and through a process of density amplification by the organizing absorption of mass, the force that pulls straight is a boundary remover. All orbiting-particle systems are in the act of balancing the force that pulls-straight,(infinity & open loop vectoring) with the force that pushes & bends, (finite & closed-looped vectoring) and or the boundary producer. For there is no limit as to how small something can be… it’s the vorticity of a vortex in size & time coordinates that provides the clue to entanglement… under-square, square and over-vortexs can produce spiritual heavenly bodies and or the spherical vortex!

… “The Entanglement” is not well understood phenomenon and it will illuminate the dark corners of our understanding of the Universe…
