The evidence for the Big Bang is overwhelming, but we cannot describe what goes on in that event. We can’t accurately call it a moment; time as we know it did not exist. Our science stops making sense ...

While the ΛCDM model has been a cornerstone of cosmology, it is showing its limitations as researchers seek to explain observations beyond its scope. (CREDIT: ESO/L. Calçada/spaceengine.org) The ...

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually spectacular simulations ever run on a supercomputer. By folding general ...

Asking what existed before the Big Bang is often dismissed as meaningless, since traditional physics breaks down when pushed that far back in time. Yet a new paper published in Living Reviews in ...

BOSTON (AP) — A letter written by Albert Einstein in which he writes out his famous E = mc2 equation has sold at auction for more than $1.2 million, about three times more than it was expected to get, ...

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. When you purchase through ...
