MICROSCOPE Mission Presents Most Precise Test of General Relativity’s Weak Equivalence Principle In new research, a team of scientists demonstrates the most precise test ever…
The Gravitational Constant The gravitational constant G determines the intensity of gravity, the force that pulls the Earth in its orbit around the sun or…
Using Newton’s laws of physics, we can model the motions of planets in the Solar System quite accurately. However, in the early 1970s, scientists discovered…
An international group of astronomers, led by a physicist at the University of St Andrews, has revived an alternative gravity theory. Headed by Dr. Indranil…
Sustained human presence in space has been a core goal of NASA for decades. NASA’s recent Plan for Sustained Lunar Exploration and Development lays out…
How can Einstein’s theory of gravity be unified with quantum mechanics? It is a challenge that could give us deep insights into phenomena such as…
The search for signatures of quantum gravity forges ahead. From a distance, sand dunes seem flat and wrinkle-free, like silk sheets covering the desert. However,…
As humanity continues its exploration of the universe, the low-gravity environment of space presents unusual challenges for scientists and engineers. Researchers at the FAMU-FSU College…
Technion researchers have found an effective solution to the famous age-old, three-body problem in physics. The three-body problem is one of the oldest problems in…
For many years now, astronomers and physicists have been in a conflict. Is the mysterious dark matter that we observe deep in the Universe real,…
Allowing for quantum corrections, the Einstein-Lovelock theory describes black holes with an equation that contains an infinite number of terms. However, according to a RUDN…
The temporal evolution of the universe, from the Big Bang to the present, is described by Einstein’s field equations of general relativity. However, there are…
How did the universe begin? How does quantum mechanics, the study of the smallest things relate to gravity and the study of big things? These…
Symmetry has been one of the guiding principles in physicists’ search for fundamental laws of nature. What does it mean that laws of nature have…
Trapped atoms, suspended aloft on a lattice of laser light for as long as 20 seconds, allow for highly sensitive measurements of gravity, according to…
Einstein’s theory of General Relativity is world famous – but it might not be the only way to explain how gravity works and how galaxies…
A newly published study details how a team of physicists simultaneously measured gravity with cold atoms at three different heights to achieve the first direct…
By combining GRAIL gravity data with computer models of large asteroid impacts and known details about the geologic evolution of impact craters, scientists were able…
