Physicists at Goethe University Frankfurt find new solution to Einstein’s general theory of relativity. If gravitational condensate stars (or gravastars) actually existed, they would look…
Why does gravity pull us down and not up? Gravity is the reason things with mass or energy are attracted to each other. It is…
A team of Princeton astrophysicists has now determined conclusively that energy close to black hole M87* is pushing outward, not inward, a longstanding debate within…
Researchers have derived a new wave equation, linking wave mechanics with the general theory of relativity and the arrow of time, offering solutions to long-standing…
Scientists have discovered that cosmic structures grow slower than Einstein’s Theory of General Relativity predicts, with dark energy playing a more dominant inhibitory role than…
Scientists have confirmed that intrinsic alignments of galaxies can probe dark matter and dark energy on a cosmological scale, supporting general relativity at vast spatial…
Scientists are investigating the use of Earth’s seismic motions to test alternative models of gravity beyond Einstein’s general theory of relativity. By analyzing seismic waves…
Researchers from the Institute of High Energy Physics of the Chinese Academy of Sciences examined the validity of the theory of relativity with the highest…
JILA physicists have measured Albert Einstein’s theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that…
One of the major issues in general relativity that separates it from other descriptions of the universe, like quantum physics, is the existence of singularities….
Published in Nature Astronomy the work which shows the unprecedented accuracy with which gravitational wave observations by the space interferometer LISA will be able to…
Since Einstein formulated his theory of general relativity (GR), the geometric theory of gravity that fundamentally altered our view of the universe, more than a…
The theory of general relativity passes a range of precise tests set by pair of extreme stars. An international team of researchers from ten countries…
Researchers at the University of East Anglia and the University of Manchester have helped conduct a 16-year-long experiment to challenge Einstein’s theory of general relativity….
Researchers study cosmic expansion using methods from many-body physics. It is almost always assumed in cosmological calculations that there is an even distribution of matter…
Further confirmation of Einstein’s theory of general relativity. The galaxy Messier 87 (M87) is located 55 million light-years away from Earth in the Virgo constellation….
Small modeling errors may accumulate faster than previously expected when physicists combine multiple gravitational wave events (such as colliding black holes) to test Albert Einstein’s…
