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

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

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense." ...

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

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

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

All of this is calculated with the equations that underpin general relativity: Einstein's field equations. "The way that the space-time curves is determined by the Einstein field equations ...

The new insight could lead to a deeper understanding of black-hole microstructure in theoretical physics by redefining the conception of a black hole by mapping out their detailed structure.

If dark energy is weakening, it stands to reason that eventually gravity will become dominant and the universe will begin to ...
