Quantum Gravitational Waves in Space

An experiment at Caltech is trying to see if space itself is quantum mechanical. This would mean that gravitons should be like popping out of the vacuum all the time. And so we talked about one possible experiment that might look at that using falling diamonds. There's another interesting potential experiment happening also, right? That's right. And this one is being developed and built in your backyard. Like literally my backyard. Look at your window man. You ever wonder what those people can do? Whoa, what? No, it's at Caltech. Both the theorists and the experimentalists are at Cal tech. It's a really cool idea.
