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 ...
Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...

Unifying physics’ biggest divide: Equation links Einstein’s relativity, quantum mechanics
Several physicists have proposed theories that try to unite quantum mechanics with Einstein’s general theory of relativity.

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 general theory of relativity is a landmark in our understanding of the universe. It gave rise to the notion of a spacetime continuum against which all physical phenomena play out.
A scion of a renowned family of physicists, he helped set the stage for what has been called the golden age of black hole astrophysics. By Dennis Overbye James Bardeen, who helped elucidate the ...
