The grandfather paradox is just one of the thorny logical problems that arise with the concept of time travel. But one physicist says he has resolved them.

Scientists at CERN's ALICE detector are replicating conditions found during the Big Bang, attempting to get to the bottom of how matter came to dominate over antimatter.

Atoms make up everything around us, but do these building blocks of matter ever actually touch?

The infinite monkey theorem is a fun thought experiment, but does it actually apply to our finite world?

A math problem delineating the largest-size sofa that can fit around a corner has finally been solved, though it may not help you move.

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.

Hurricane Helene sent gravity waves rippling through the atmosphere far above the southeastern United States, new NASA images reveal.

Primordial black holes may be exploding throughout the universe. If we can catch them in the act, it could pave the way to new physics, a study suggests.
