In Fake Universes, Evidence for String Theory
If string theorists can show that their framework is the only consistent theory of quantum gravity, does that make it true even without tangible evidence?
Betting on the Future of Quantum Gravity
New calculations suggest physicists may someday discover a fundamental theory of gravity, but it could require a radical new perspective on the universe.
Physicists Eye Quantum-Gravity Interface
Physicists have devised experiments that can probe the interface between quantum mechanics and general relativity.
A Jewel at the Heart of Quantum Physics
Physicists have discovered a jewel-shaped geometric object that challenges the notion that space and time are fundamental constituents of nature.
