General relativity

Ripples in space-time have been detected a century after Einstein predicted them, launching a new era in astronomy.

The physical nature of computers might reveal deep truths about their uniquely powerful abstract abilities.

Explore the deepest mysteries at the frontier of fundamental physics, and the most promising ideas put forth to solve them.

By replacing black holes with fuzzballs — dense, star-like objects from string theory — researchers think they can avoid some knotty paradoxes at the edge of physics.

Imagine the fabric of space-time peeled back layer by layer.

New tools may reveal how quantum information builds the structure of space.

A bold new idea aims to link two famously discordant descriptions of nature. In doing so, it may also reveal how space-time owes its existence to the spooky connections of quantum information.

Physicists have devised experiments that can probe the interface between quantum mechanics and general relativity.
