If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of ...

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks.

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 ...

Dark matter, dark energy, the Hubble tension: underpinning these theories is Einstein’s general theory of relativity, which treats space and time as a unified “spacetime” and considers ...

Before it shut down, a telescope in Chile captured the universe's baby photos, just 380,000 years after the Big Bang. These ...

A blackboard at a U.K. university is believed to be the only one of its kind that has both Albert Einstein's scientific notations and his signature.

Top quarks follow the rules of special relativity day and night. Is there a time of day or night at which nature's heaviest elementary particle stops obeying Einstein's rules? The answer to that ...

The new findings come from the Dark Energy Spectroscopic Instrument (DESI), which sits on a telescope at the Kitt Peak ...

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 ...

However, some theories suggest that, at extremely high energies, special relativity fails as a result ... and thus no evidence of top quarks defying Einstein no matter what way proton beams ...
