Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

Lightning is one of the most familiar spectacles in the sky, yet the exact spark that starts a bolt has remained stubbornly out of reach. Now a physicist has managed to trap a microscopic particle and ...

Physicists have determined that most of the universe is dark matter -- invisible to us but affecting the universe anyway.

For experimental physicists, the latest measurement of the muon is the best of times. For theorists there's still work to do.

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light ...

Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, ...

Humanity has achieved remarkable feats, yet 95% of the universe remains invisible and unexplained. Our theories, general ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators.

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

Cosmologists have traced the Big Bang’s earliest moments with great care, from the explosive inflation that set spacetime in ...

The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...
