Brian Greene, Columbia University physicist and co-founder of the World Science Festival, explains how today's physicists and mathematicians use an Einsteinian formula to explain the universe that ...

Albert Einstein is easily one of the most brilliant physicists who ever lived. His theories of general relativity changed our understanding of the cosmos, as did his work on quantum theory. But his ...

Spacetime is often described as the stage on which the universe unfolds, a four-dimensional blend of space and time that bends, stretches and shifts as matter and energy move through it. However, ...
