Watching one of Feynman's lectures, I came across something that puzzled me. What was Feynman referring to when he said the following?
What goes on in no matter how tiny a region of space and no matter how tiny a region of time, according to the laws as we understand them today, takes a computing machine an infinite number of logical operations to figure out. Now, how could all that be going on in that tiny space? Why should it take an infinite amount of logic to figure out what one stinky little bit of space-time is going to do?
— Richard Feynman
Edit: I see a close vote was cast, the reason being that the question is unclear. My question is, why would Feynman say it would take an infinite amount of logic to simulate even a small region of space-time?
