At the heart of this puzzle lies light-by-light scattering, a quantum process where particles of light, or photons, briefly transform into other particles. Ordinarily, light waves pass through each ...

Second only to black holes, neutron stars – incredibly dense star remnants – are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time in ...

Add Yahoo as a preferred source to see more of our stories on Google. The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four ...

When two atomic nuclei collide at near-light speeds, they generate temperatures more than 1,000 times higher than those at the center of the sun. These collisions briefly produce a state of matter ...

Fundamental particles called quarks can be created in quantum-correlated pairs. These correlations can be passed on to larger particles that form from the quarks. The strong force differs from others ...

The Sun has a powerful magnetic field created by the movement of hot, charged gases inside it. The magnetic field lines stretch out from the Sun's interior to the surface and into the solar atmosphere ...

The magnetic moment of the muon—a tiny property of a tiny particle—has long puzzled physicists. Experiments and theory haven't quite matched up, leaving open the thrilling possibility of discovering ...
