Is Cassacity Really Needed?

In quantum mechanics, we don't really know whether the cat is alive or dead anywayis right? That's right. We've added in another element here, which is causality. Because now cono mechanics is influencing the very shape of space, which determines which events can h in what order. And so maybe the key to finding a theory of quatumgravity and revealing the deep nature of the universe is to give up on causality.
