You can say the universe has a split personality. Or better said, our physical models of the universe are the ones fractured.

The new baryon “Xi-cc-plus” decays into other particles almost instantly, but its existence could paint a clearer picture on ...

Amid the many mysteries of quantum physics, subatomic particles don't always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even ...

Over a century ago, Ernest Rutherford discovered the proton by splitting the atom in a laboratory in Manchester. Today, ...

They say you can never trust an atom because they make up everything. This week, we’re shrinking down and getting literally into the heart of the matter. We’ve covered the periodic table and all its ...

Something unseen is influencing muons, and the findings could lead to a bigger quantum uproar than the Higgs boson did. Rae Hodge was a senior editor at CNET. She led CNET's coverage of privacy and ...

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 ...
