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

"Different approaches to quantum gravity will place different importance on different terms in the equations, but they all suggest that Einstein's equations need to be refined." By incorporating ...

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

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 team of physicists have discovered a new approach that redefines the conception of a black hole by mapping out their ...

The behavior of spacetime is described by Einstein's equation (i.e. Einstein's field equations) from General Relativity. To ...

“By introducing the G-field, we obtain the modified Einstein equations and the equations of motion for the matter and the ...

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