China is nearing completion of an advanced facility to measure neutrinos, the smallest subatomic particles known to physicists. Its underground central sphere will soon be sealed off and filled with ...

The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Physicists have found provocative evidence that a subatomic particle behaves in a way that cannot be explained by the prevailing model of how matter works on the smallest scale. If confirmed, the ...

Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...

Scientists at CERN spent the last decade waiting for a one-in-ten-billion chance event, and now they’ll spend the next few years figuring out whether it challenges the laws that (we think) govern the ...
