My favourite thing about Issac Newton is that his gravity stuff is good enough to get you to the moon, but isn’t actually (if I understand properly, which isn’t guaranteed) correct. It doesn’t work at the sub-atomic level, which is where quantum physics comes in, I think.

So gravity actually doesn’t exist, or at least not quite as Newton described.

If any scientist wants to chime in and clarify (or indeed refute) this, I’d appreciate it.
