"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

Wormholes have fascinated scientists and science fiction fans alike, but how do they really work? From Einstein’s field ...

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the ...

Albert Einstein on a bill of 5 Israeli Pounds. A truly spectacular unpublished autograph manuscript produced by German physicist Albert Einstein (1879-1955) and exploring his celebrated Unified ...

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another.

Beginning from Einstein’s field equations, Ogonowski reveals their ability to describe all known physical interactions, including those described by classical electromagnetism.

By the way, the Einstein field equations are pluralized because these tensors are multi-part objects–it’s really a set of 10 partial differential equations. But despite ...
