Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a ...

The apparent inability of physics' string theory to be proved right or wrong is one of the stickiest – and argument-generating – problems in modern science. But now researchers at the University of ...

If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up.

Brian Greene, a professor of physics and mathematics at Columbia University and director of Columbia’s Center for Theoretical Physics, is the author of “The Elegant Universe” and “Until the End of ...

Abstract, mathematically complex and (so far) unsupported by direct experimental evidence, string theory attracts plenty of criticism. Yet it remains an incredibly active area of research, with ...
