Enter the quantum realm with Live Science, where the regular rules of physics don't apply and objective reality doesn't exist. Quantum physics is a field of science in which researchers study energy and matter at their most fundamental level.
At Live Science, our expert writers and editors break down the most important and stunning quantum experiments, explain quantum cognition — the physics theory that could predict human behavior — and discover how physicists are making light move simultaneously forwards and backwards in time. So, if you're ready to explore the weird world of quantum mechanics, check out the latest news, features and articles about quantum physics.

Tweak to Schrödinger's cat equation could unite Einstein's relativity and quantum mechanics, study hints
By Andrey Feldman published
Physicists have proposed modifications to the infamous Schrödinger's cat paradox that could help explain why quantum particles can exist in more than one state simultaneously, while large objects (like the universe) seemingly cannot.
