For more than a century, quantum mechanics and Albert Einstein’s theory of general relativity have each passed countless tests, but physicists have struggled to reconcile the two. Now, scientists in ...

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at quantum scales.

The unification of quantum theory and the general theory of relativity, describing gravity, is one of the most important challenges in science. Einstein’s general theory of relativity is based on the ...

Dark energy, which is believed to be responsible for the accelerated expansion of the universe, may be a manifestation of the quantum properties of space itself. Savvas Kushiappas, a physicist from ...
