Q: What never fails to blow your mind in physics?
A: 1) The fact that an electron has no known size — it’s smaller than the smallest measurement we have ever made of anything.
2) That Quarks come only in pairs: If you try to separate two of them, the energy you sink into the system to accomplish this feat is exactly the energy to spontaneously create two more quarks – one to partner with each of those you pulled apart.
3) That the space-time structure inside a rotating black hole does not preclude the existence of an entire other universe.
