Scientists at CERN, the famous Geneva-based physics lab, have just called into question one of the most hallowed equations in physics: E = MC2. Scientists, the AP explains, have clocked subatomic ...

Back in 2000, a team of physicists led by Lijun Wang at the NEC Research Institute in Princeton, USA, pulled off a mind-bending experiment. They fired a precisely shaped laser pulse through a special ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...

(via Sabine Hossenfelder) Recently, the James Webb Space Telescope observed signals that moved faster than the speed of light. Does this mean that faster-than-light travel is real? If not, what ...

For more than half a century, faster than light travel has lived in the realm of television scripts and paperback science fiction. Now a cluster of theoretical breakthroughs is forcing physicists to ...

If there is an absolute law in the universe, it’s that nothing can travel faster than the speed of light. For science-fiction enthusiasts, that’s a bit depressing. Space is big, and while the speed of ...

When I was a teenager, I was—shockingly, I know—deeply nerdy. At a science-fiction convention, I bought a button that read, “186,282 miles/second: Not just a good idea, it’s the law.” It was poking ...
