Standard Model: Particles, Forces, and What It Cannot Explain
The Standard Model classifies all known elementary particles and describes three fundamental forces. It is the most tested theory in physics, yet it...
Zero Point Energy: Why Nothing in the Universe Is Ever Still
Zero point energy is the residual motion that persists in every quantum system, even at absolute zero.
Massless Particles: Why They Must Travel at Light Speed
Massless particles have zero invariant mass and must travel at the speed of light in vacuum. The photon is the only confirmed example.
Fermions: The Particles That Build All Matter
Fermions are half-integer spin particles that obey the Pauli exclusion principle, building all ordinary matter.
Quantum Vacuum: Why Atoms Are Not Really Empty Space
The quantum vacuum inside every atom teems with fluctuating fields that never rest.
The Muon g-2 Anomaly That Wasn't
Muon g-2 final result from Fermilab achieves 127 ppb precision, but a revised Standard Model prediction using lattice QCD closes the gap. The...
