String theorists elide a paradox about black holes by extinguishing the walls of fire feared to surround them.
The renowned British physicist, who died at 76, left behind a riddle that could eventually lead his successors to the theory of quantum gravity.
Two leading candidates for a “theory of everything,” long thought to be incompatible, may be two sides of the same coin.
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.
If a new hypothesis about black hole firewalls proves correct, at least one of three cherished notions in theoretical physics must be wrong.
