Constantinos G. Vayenas explores the roles of neutrinos, quantum mechanics, and special relativity in baryogenesis ...

“We proved that the Einstein field equation from general relativity is actually a relativistic quantum mechanical equation,” ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. A new recipe for gravity could help ...

However, some scientists say a simple modification of Einstein's relativity might not be enough. In fact, it's possible that the discrepancies revealed by astronomical observations are hints that ...

On 25 November 1915, Albert Einstein presented his general theory of relativity at the Prussian Academy of Sciences. This theory is still considered to be the most important idea in modern physics.

By modifying Einstein's theory of general relativity, the center of a black hole with infinite curvature could be replaced by a highly curved but regular region of space-time, the researchers ...

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research ...
