You should actually watch the video. There's a very large section where he goes over how in 21 or 22 whenever the original theory was proposed and experiments we're performed with no evidence found. He was originally going to put out a video talking about it but pointing out how unrealistic and unlikely it was. Instead he waited and only put out the recent video because there was some evidence pointing to the fact that there could be a connection. Anton does not tend to be sensationalist. For such subject matter he will usually be very clear when there isn't a lot of science backing things up. It's an interesting concept and now there is possible evidence that something could be going on. And that's what he says.
