Everything that can happen, does. That's quantum mechanics. But this does not mean everything happens. The rest of physics is about describing what can happen and what can't.

Coral is a very beautiful and unusual animal. Each coral head consists of thousand of individual polyps. These polyps are continually budding and branching into genetically identical neighbors.

The mathematics of quantum mechanics very accurately describes how our universe works. And it tells us our reality is continually branching into different possibilities, just like a coral.

I think the universe is pure geometry - basically, a beautiful shape twisting around and dancing over space-time.

Everything that can happen, does. That's quantum mechanics. But this does not mean everything happens. The rest of physics is about describing what can happen and what can't.

What physics tells us is that everything comes down to geometry and the interactions of elementary particles. And things can happen only if these interactions are perfectly balanced.

You cannot think when you're ecstatic.
