Physicists propose test for loop quantum gravity
Theorists apply loop quantum gravity theory to black hole
Revised theory of gravity doesn't predict a Big Bang
New Law of Physics Could Explain Quantum Mysteries
Time travel theory avoids grandfather paradox
For the first time, astronomers have measured the radius of a black hole
(Phys.org)—The point of no return: In astronomy, it's known as a black hole—a region in space where the pull of gravity is so strong that nothing, not even light, can escape. Black holes that can be billions ...
Looking at quantum gravity in a mirror
Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale ...
Spacetime May Have Fractal Properties on a Quantum Scale
Gravity Probe B confirms two Einstein theories
(PhysOrg.com) -- Stanford and NASA researchers have confirmed two predictions of Albert Einstein's general theory of relativity, concluding one of the space agency's longest-running projects.
Can R2 gravity explain dark matter?
Light from galaxy clusters confirms theory of relativity
All observations in astronomy are based on light emitted from stars and galaxies and, according to the general theory of relativity, the light will be affected by gravity. At the same time all interpretations ...
Dark Energy is real: WiggleZ galaxy project proves Einstein was right again
(PhysOrg.com) -- An Australian-based astronomy team, co-led by Professor Michael Drinkwater from the School of Mathematics and Physics (SMP) at The University of Queensland (UQ), has shown that the mysterious ...
Gas rich galaxies confirm prediction of modified gravity theory
(PhysOrg.com) -- Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity know as MOND according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. ...
New method proposed for detecting gravitational waves from ends of universe
A new window into the nature of the universe may be possible with a device proposed by scientists at the University of Nevada, Reno and Stanford University that would detect elusive gravity waves from the ...
