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 shows ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged.

Inconsistencies with Einstein’s ideas have led some to believe ... the theory of a one percent glitch when dealing with ...

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 ...

Teleparallel gravity is an alternative theory to general relativity, also devised by Einstein. This "other ... without invoking a cosmological constant," Rivera says. Rivera and her colleagues ...

Einstein's theory of general relativity predicts gravitational memory, where space-time retains imprints from passing gravitational waves. Researchers are exploring if the cosmic microwave ...

The James Webb «Space Telescope» took a picture of a gravitational lens with a very unusual shape that creates the effect of an Einstein ring. The European Space Agency (ESA) has named this lens the ...

3. Einstein's theory of relativity predicted the presence of ripples in spacetime called gravitational waves. Einstein had already demonstrated that matter can curve space, so it only follows that ...

"Since it is a direct prediction of Einstein's theory of general relativity, its observation would serve as a confirmation of the theory, much like the observation of gravitational waves by LIGO ...
