Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

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 ...

It was co-written with his lifelong friend, the Swiss engineer Michele Besso. LONDON -- A rare manuscript by Albert Einstein that changed the course of modern science was just sold for over 13.3 ...

A rare 54-page manuscript featuring preliminary calculations for Albert Einstein’s general theory of relativity sold for about $13 million at auction in Paris Tuesday to an unknown buyer — almost four ...

Several physicists have proposed theories that try to unite quantum mechanics with Einstein’s general theory of relativity.

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges. Now, ...

The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...
