The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter interact through fundamental forces, such as the ...

The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead-208 with ions to excite the subatomic particles and determine ...

WASHINGTON, Aug 10 (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their understanding of physics - perhaps some unknown particle ...

As the nucleus splits, it also releases its neutrons. These neutrons bounce around at incredible speeds until some eventually collide with other nuclei. This sets off a chain reaction as each collision results in the release of more heat and more neutrons.

The ancient Greeks speculated that it might be air, fire or water. A century ago, physicists felt sure it was the atom. Today, we believe that the deepest layer of reality is populated by a diverse cast of elementary particles, all governed by quantum theory.

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the universe — or so it seemed. The equations that ...

The Nobel-Prize-winning physicist Peter Higgs has died at age 94. He was celebrated for his work on the mass of subatomic particles. Today the University of Edinburgh announced the death of the Nobel Prize-winning physicist Peter Higgs. As NPR's Geoff ...

For the first time, scientists have observed quantum interference—a wavelike interaction between particles related to the weird quantum phenomenon of entanglement—occurring between two different kinds of particles. The discovery could help physicists ...

Scientists have discovered a common thread between the monstrous black holes that lurk at the hearts of galaxies and subatomic glass condensates created in collisions of atomic nuclei. When you purchase through links on our site, we may earn an affiliate ...

The idea of powering a house with a single atom might seem like science fiction, but recent advancements in nuclear physics and energy research suggest it could be closer to reality than we think. Scientists are exploring the incredible energy potential ...
