What is everything made of? It’s the fundamental question that lies at the heart of particle physics. Today, scientists are using gigantic, atom-smashing particle accelerators to probe deeper into the ...

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 ...

To cheers and standing ovations, scientists at the world's biggest atom smasher claimed the discovery of a new subatomic particle Wednesday, calling it "consistent" with the long-sought Higgs boson — ...

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 ...

GENEVA - Physicists say they have all but proven that the "God particle" exists. They have a footprint and a shadow, and the only thing left is to see for themselves the elusive subatomic particle ...

BOSTON (Reuters) - Scientists are still sorting out the details of last year's discovery of the Higgs boson particle, but add up the numbers and it's not looking good for the future of the universe, ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

With the nature of the universe's two most elusive components up for debate, physicists have proposed a radical idea: Invisible particles called tachyons, which break causality and move faster than ...
