Scientists Discovered a Particle Made Entirely Out of Force

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/5rqQFYd... Cross two beams of light and they slip straight through one another, because a force is supposed to live only in the gap between things, never to be a thing itself. One force quietly breaks that rule, and beneath Beijing physicists have caught it doing the impossible. What would it mean for a particle to be made of nothing but force? Tonight we follow the fifty-year hunt for that particle, from a whimsical prediction to ten billion collisions, and sit with what it does to the line between matter and force. Get comfortable and let this quiet walk through the strong force keep you company tonight. Subscribe to Sundown Science if you enjoy taking the long way around the universe.
