Physics

Physicists plan to leave no stone unturned, checking whether dark matter tickles different types of detectors, nudges starlight, warms planetary cores or even lodges in rocks.

An exercise in pure mathematics has led to a wide-ranging theory of how the world comes together.

It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more than it is changing now.

The newly-measured rate of a key nuclear fusion process from the Big Bang matches the picture of the universe 380,000 years later.

Cora Dvorkin discovered new possibilities for what dark matter could be. Now she’s devising unorthodox ways to identify it.

Once missing in action, middleweight black holes have finally been detected. Now researchers are trying to figure out how they grow from small ones.

In a landmark series of calculations, physicists have proved that black holes can shed information.

We’ve created a new way to explore the fundamental constituents of the universe.

Our new series of articles explores the search for fundamental structure at the edge of science.
