Thanks to Einstein's theory of relativity, numerous tests have concluded tangible effects on how we on Earth record and measure the passing of time.

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square ...

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 novel theory of 'wavy space-time' suggests that the division between our best descriptions of the universe on its smallest and largest scales may be because gravity does not play by quantum rules.

Gravity Probe B The Gravity Probe B (GP-B) satellite is a collaboration between NASA and Stanford University and was launched in 2004 with an aim to study two effects predicted by general relativity, ...

A research team measured and found that the size of this black hole's shadow aligns with Einstein's theory of relativity -- or matter warping space-time to create gravity.

An international team of astronomers has conducted a new test of Albert Einstein's famous theory of general relativity (GR), finding that it works even in extreme gravitational environments ...

The big unsolved problem of modern physics is reconciling its two pillars: general relativity and quantum mechanics. Quantum gravity would unite them ...

Gravity Probe B is an experiment developed by NASA and Stanford University to precisely test two predictions of Albert Einstein's general theory of relativity, measuring how space and time are ...
