Physics is the scientific study of matter, energy, motion, forces and the fundamental laws that govern nature across scales. It includes classical mechanics, electromagnetism, thermodynamics, relativity and quantum theory. Physics underpins technologies from electronics and medical imaging to energy systems, while providing models for phenomena from subatomic particles to galaxies.
A newly reported mathematical result narrows the range of viable ways to extend particle physics, offering guidance for future experiments without yet constituting evidence for new particles or forces.
A reported experiment reconstructs a photon's quantum evolution from more than 1.4 million path contributions, offering an unusually direct operational test of Feynman's path-integral framework.
The celebrated solar-neutrino mystery was resolved in 2001, but new measurements are refining the particle physics that emerged from that breakthrough.
Recent disputes over topological qubits show that quantum computing needs stronger norms for data sharing, independent replication and comparable performance evidence.
A RHIC experiment has linked spin correlations in short-lived hyperons to correlated strange-quark pairs in the quantum vacuum, opening a new experimental route into how the strong force makes most visible mass possible.
An outdoor experiment has shown that carefully filtered and concentrated sunlight can pump a crystal to produce polarization-entangled photon pairs, although the result remains an early-stage preprint demonstration rather than a replacement for laser-based quantum hardware.
