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.
Antony Garrett LisiThe 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.
Antony Garrett LisiEverything 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.
