“The birth of a star is not that interesting. It’s just a stellar nebula turning a protostar. The old age of a star is also not that interesting: it’s either a red giant or a red supergiant. But the death of a star is really interesting. There’re loads of intricate options that can happen!”

“Weather is a chaotic system.”

“If a physics constant suddenly popped up in pure mathematics, that would be really weird. If there is more than one universe, that would mean either that mathematics only exists in this particular universe, or that one of the laws of physics in our universe would go through mathematics to all other universes in existence. So for example, the speed of light would be the same in all universes, or Planck’s constant.”

“If the Universe is infinite, it’s a fractal! Which means it contains itself!”

“The inverse function of the reciprocal is itself!”
