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

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

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 ...

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 ...

Electrodynamics (electricity and magnetism) is governed by Maxwell's equations and the Lorentz force law, but that left it a little broken. It would take Albert Einstein inventing special relativity ...

It may be the world’s most famous equation, but what does E=mc2 actually mean? Shortly after completing his paper on special relativity, in 1905, Einstein realized his equations applied to more ...

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 ...

Supermazes” are theoretical structures that provide a fresh blueprint for understanding the microscopic complexity of black ...
