During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String ...

A new theory links gravity to quantum entropy and introduces the G-field, possibly explaining dark matter and cosmic ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

Einstein believed that black holes didn't really exist. But they do: that much we know. We don't know much else about them.

In the vast universe, galaxies rotate in ways that don’t make sense if only visible matter is considered. For almost a ...

These disturbances in spacetime were predicted by Albert Einstein through his theory of general relativity, where he described gravity as the warping of spacetime caused by massive objects.

Researchers say they may have achieved Einstein's vision of a "unified field theory" that can unite two of nature's ...

The mysterious force called Dark Energy, which drives the expansion of the Universe, might be changing in a way that ...

Ronald Mallett, professor emeritus at the University of Connecticut, is most known for his theory on how time travel is possible.

Physicists have taken a bold step beyond Einstein's special theory of relativity, proposing an expansion of special ...
