Physics

People have known about magnets since ancient times, but the physics of ferromagnetism remains a mystery. Now a familiar puzzle is getting physicists closer to the answer.

An analysis of lunar craters has found that we’ve been living in a relatively violent period in cosmic history.

Subatomic particles called muons are thought to have streamed through the atmosphere and irradiated megafauna like the monster shark megalodon.

Astronomers couldn’t find enough satellite galaxies orbiting the Milky Way. Now they have the opposite problem.

Dark matter may occasionally interact with minerals in the earth, leaving telltale tracks that physicists hope to decipher.

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.

The field of fundamental physics is experiencing both a period of confusion and an openness to new ideas.

In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.
