How is it possible to tell if a space rock will one day collide with the Earth?

A mathematical test for the nature of space-time – the fabric of physical reality – may be the first step towards novel computer-like devices that process information using gravity ...

An artist's impression of Earth's gravity well. The idea that gravity is the result of the curvature of space-time is a core principle of Einstein's theory of general relativity.

By understanding the churning region near singularities, physicists hope they might be able to reconcile gravity and quantum mechanics.
