Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest ...

Trillions of times smaller than a grain of sand and smaller than an atomic proton or neutron, quarks are among the smallest particles in the universe. They are essentially building blocks for ...

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...

(Nanowerk News) Our home planet is bombarded with particles from outer space all the time. And while we are mostly familiar with the rocky meteorites originating from within our solar system that ...

In their search for more flavors of Higgs bosons, a team of researchers at CERN stumbled across what could be evidence of the smallest matter-antimatter particle ever. The hypoethical particle, known ...

In CUriosity, experts across the CU Boulder campus answer pressing questions about humans, our planet and the universe beyond. Previously, astrophysicist Jeremy Darling tackled: “What is the biggest ...

Physicists have placed a new limit on how big the elusive neutrino can be—one of the universe’s smallest known particles—a limit that makes other subatomic particles look as big as black holes by ...

Scientists at CERN spent the last decade waiting for a one-in-ten-billion chance event, and now they’ll spend the next few years figuring out whether it challenges the laws that (we think) govern the ...
