Physicists working to disprove "Lorentz invariance" -- Einstein's prediction that matter and massless particles will behave the same no matter how they're turned or how fast they go -- won't get that ...

Fermilab physicist Don Lincoln explains a well-known thought experiment examining the consequences of special relativity. “Time waits for no man” goes the saying, and it appears to be true. Inexorably ...

Fermilab accelerator complex in Batavia, IL, with the accelerator tunnels highlighted in red. At least about a key element in his Special Theory of Relativity? Fermilab, the US accelerator lab, is ...

Neutrinos are the big nothings of subatomic physics. Nearly massless and lacking an electric charge, these ghostly particles interact so weakly with other types of matter that more than 50 trillion of ...

GENEVA (AP) — One of the very pillars of physics and Einstein's theory of relativity — that nothing can go faster than the speed of light — was rocked Thursday by new findings from one of the world's ...

GENEVA, Switzerland - One of the very pillars of physics and Einstein's theory of relativity - that nothing can go faster than the speed of light - was rocked Thursday by new findings from one of the ...

The news that particles called neutrinos may travel faster than light has been met with shock, skepticism and excitement from physicists around the world since it was officially announced this morning ...
