Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

The General AntiParticle Spectrometer experiment is suspended from a football-field-sized balloon about 24 miles above the ...

What is the nature of dark matter? A new experiment led by Columbia University physics professors aims to find out.

Physicists have spent decades chasing two grand technological dreams: harnessing fusion power and uncovering the nature of ...

Do you know which are the most abundant particles in the universe? It is neutrinos — small, chargeless, and nearly massless subatomic particles that either don’t interact with matter at all or ...

An Antarctic experiment looking to detect dark matter in space led by University of Hawaii Manoa was launched on Dec. 15.

Andrea Gallo Rosso is a member of the ALPHA collaboration. He receives funding from the Swedish Research Council. Several experiments have aimed to unveil what it’s made of, but despite decades of ...

The nature of dark matter is one of the leading mysteries in modern astronomy. In fact, the name "dark matter" is essentially a placeholder for something astronomers know is there but can't yet ...

Dark matter is claimed to make up over 80% of all matter in the universe, but scientists have never seen it. We only assume it exists because, without it, the behavior of stars, planets and galaxies ...

Dark matter is thought to outnumber regular matter by a factor of five to one – so why can’t we find the stuff? A new study proposes looking for it from space, using a satellite containing a ...

The original version of this story appeared in Quanta Magazine. The end is brutal for electrons hurtling at 99.9999999 percent of the speed of light through SLAC National Accelerator Laboratory’s ...
