The way you think about atoms may not be quite right.
A reader asks: "If atoms are mostly empty space, then why does anything feel solid?" James Beacham, a post-doctoral researcher with the ATLAS Experiment group of The Ohio State University, explains.
The Higgs boson is the only fundamental particle known to be scalar, meaning it has no quantum spin. This fact answers questions about our universe, but it also raises new ones.
The Standard Model is one of the most well-tested theories in particle physics. But scientists are searching for new physics beyond it.
In particle physics, “annihilation” is a transformation.
Building experimental evidence suggests that the electron, muon and tau may feel different forces.
Just over 40 years ago, a new theory about the early universe provided a way to tackle multiple cosmological conundrums at once.
There’s no one best way to build a telescope.
