Fundamental physics

How do scientists know what percentages of the universe are made up of dark matter and dark energy?

The Dark Energy Spectroscopic Instrument will measure light from 35 million cosmic objects for new insights into what causes the universe to expand faster and faster.

The scientists develop methods to study neutrinos from star explosions and search for unknown particles and forces with possible ties to dark matter.

The Standard Model is far more than elementary particles arranged in a table.

The first website to be hosted in the US has grown to be an invaluable hub for open science.

In its final run, the LUX experiment increased its sensitivity four-fold, but dark matter remains elusive.

Before Hitomi died, it sent back X-ray data that explain how turbulent motions may prevent cooling of hot gas.

Project Poltergeist led to the discovery of the ghostly particle.

Meet the world’s deepest underground physics facilities.

KIPAC researchers mourn the loss of the Hitomi spacecraft but are thrilled about the data it was still able to capture.

Experiments at the Large Hadron Collider are once again recording collisions at extraordinary energies.

Astronomers around the world are looking for visible sources of gravitational waves.
