Neutrino lasers: It’s an idea that many physicists didn’t see coming. At first glance, physics suggests that it would be impossible to make a laser of neutrinos, famously elusive subatomic particles.

Scientists have ample evidence to prove the Earth is a sphere. But some social media users claim to have devised an experiment showing the earth is flat. The post shows a green laser beam projected ...

Google’s parent company, Alphabet, is still experimenting with hooking up remote towns to the Internet via frickin’ laser beams. Today, Alphabet’s moonshot “X Lab” shared an update on Project Taara, ...

A donut is not a bun. From a mathematical point of view, they are two fundamentally different objects: The donut has a hole, the bun does not. A circle inside the donut around its hole in the center ...
