In 2020, a group of MIT researchers detected an anomaly in the nuclei of ytterbium atoms. They said that the nuclei’s strange behavior might be indicative of a “dark force” caused by a currently-undiscovered mystery particle that might make up dark matter. In 2020, the anomaly only had a significance of 3 sigma. But now, another group has confirmed it at a whopping 23 sigma! What does that mean

Just a brief explanation for what happened with last week's climate science video. Sorry for the confusion which, in hindsight, was rather unnecessary.

Physicists are stuck on trying to figure out why gravity and quantum mechanics don’t get along. For almost 100 years now, they have been looking for a theory of quantum gravity to solve the problem. But one of the most general expectations of a quantization of gravity is that space also has quantum fluctuations. And a team of researchers from Caltech now says they’ve got a tabletop experiment
