quantum physics

Using a groundbreaking new technique, researchers have unveiled the first detailed image of a photon — a single particle of light — ever taken.

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there.

Physicists showed that photons can seem to exit a material before entering it, revealing observational evidence of negative time

New research suggests that black holes may actually be "frozen stars," bizarre quantum objects that lack a singularity and an event horizon, potentially solving some of the biggest paradoxes in black hole physics.

The universe is expanding at an ever accelerating rate — and tiny wormholes that bore through the fabric of space-time might be to blame, a new study proposes.

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest.

Using a clever laser technique, scientists have squished pairs of atoms closer together than ever before, revealing some truly mind-boggling quantum effects.

A new imaging technique, which captured frozen lithium atoms transforming into quantum waves, could be used to probe some of the most poorly understood aspects of the quantum world.

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.
