Can one vanishing particle shatter string theory — and explain dark matter? Penn physicists and collaborators at Arizona State University "test" the fallibility of a framework that seeks to ...

Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to answer one of the most fundamental open questions in modern physics: What ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe. Instead of basing the theory on the warping of space and time, we ...

Physicists working at the CERN particle physics lab said they detected a slight but significant difference in how particles of matter and antimatter decay.

Matter-antimatter asymmetry puzzles physicists. Learn how the Deep Underground Neutrino Experiment (DUNE) may find answers.

The film explores the dual nature of light, demonstrating its behavior as both a wave and a particle through an experiment involving a double slit. It shows how light creates an interference ...

What remains unknown are the origins of dark matter, and hence, what are its particle properties? Those weighty questions primarily fall to theoretical physicists like Profumo.
