New candidate particle for dark matter is one we’ve already found

Dark matter is believed to outnumber regular matter by a ratio of five-to-one, but so far it’s never been directly detected. Now, nuclear physicists at the University of York have proposed a new candidate particle that might make up the strange stuff –… Continue reading New candidate particle for dark matter is one we’ve already found

Did dark matter arise before the Big Bang?

Few things are as mysterious as dark matter, the strange substance that appears to outnumber ordinary matter by a ratio of five to one. Now, a physicist from Johns Hopkins University has outlined a new theory that helps to explain the stuff b… Continue reading Did dark matter arise before the Big Bang?

CERN searches for "dark photons," light's hypothetical cousin that could unlock dark matter

CERN experiments have been unable to detect dark photons

Dark matter is a mysterious substance that seems to permeate the universe, but detecting it is tricky on account of it not interacting with regular matter very often. Scientists have a list of particles that they’re working through as possible suspects, and now that list is a little shorter. Experiments at CERN have ruled out some types of dark photons, inching us closer to finding the elusive dark matter.

Solar Chameleons: CERN's search for dark energy particles from the Sun

Dark energy is one theory to explain the accelerating expansion of the universe, and a new ...

One of the biggest mysteries of the universe is why its expansion seems to be speeding up. Physicists have attributed it to a strange force called dark energy, but exactly how it works is largely speculative. Hypothetical “chameleon” particles could be behind dark energy, and physicists at CERN have been searching for these particles streaming from the Sun. Now, the team has reported the first results of their search.
