Fundamental physics

Physicists have good reason to believe 85 percent of the matter in the universe is currently undetectable. But not being able to see it didn’t keep students at the 42nd SLAC Summer Institute from learning about it.

A team of scientists generated a giant cosmic simulation—and now they're giving it away.

Brian Greene welcomes the Internet to physics class with World Science U.

Last year, a monster magnet set out from Brookhaven National Lab on an epic trek by land and sea to Fermilab, where it will serve as the heart of a search for evidence of new subatomic particles. Last month, researchers...

LSST Will Capture Unprecedented View of Night Sky

With two SLAC researchers in the lead, an analysis of the enigmatic Fermi bubbles has narrowed down the number of possibilities for their origin, but hasn't completely solved the puzzle.

Photon science, a spin-off of particle physics, has returned to its roots for help developing better, faster detectors.

Step on a scale and you’ll get a quick measure of your weight. Weighing galaxy clusters, groups of hundreds or thousands of galaxies bound together by gravity, isn’t so easy. But scientists have many ways to do it.

A determined volunteer gives an old detector new life as the centerpiece of a cosmic ray exhibit.

Together, three experiments, two with major SLAC contributions, will search for a variety of types of dark matter particles.

Two dark matter hunters with decades of experience between them are turning SLAC into their base of operations for LZ, the next big dark matter search.

Efforts are already underway to ensure that the data the Large Synoptic Survey Telescope  collects will be ready to be mined for scientific gold.
