It's fitting that Merriam-Webster's word of the year is gaslighting . Since a violent mob assaulted the U.S. Capitol on January 6, 2021, apologists have tried to argue that the thing everyone saw with their own eyes, captured in videos and photographs, simply wasn't what it appeared to be. If it was so violent, they say, why wasn't anyone armed? But, of course, the images show rioters using flagp

Scientists have, for the first time, developed a quantum experiment that allows them to study the dynamics, or behavior, of a special kind of theoretical wormhole. The experiment has not created an actual wormhole (a rupture in space and time), rather it allows researchers to probe connections between theoretical wormholes and quantum physics, a prediction of so-called quantum gravity. Quantum gra
