Hello, As written, I am wondering if the causality principle gets violated in QM. Do virtual particles violate the causality principles? Do instantaneous events violate the causality principle? Thank you in advance.

Thank you for your response, but can you elaborate why is it too vague?

I'm not jumping to the argument, it's just that those who were arguing seemed not to have any scientific background related. I'm simply curious. I'll define causality like this: Causal System: A system whose output(s) depend on the current/past input(s).

A simple question. I might ask this as well: Is the universe causal? The reason I'm asking this is that today I've ran into two guys having an argument about this, so I want to know. Thank you.

Thanks for the replies If it's a superposition of states, what will we see if we try to measure what's happening in a quantum vacuum? I mean we should measure a certain state, but how would we define a state in here? Please give me an example of a quantum state in a quantum vacuum. A...

Do quantum fluctuations come from "nothing"? Hello, I have two questions regarding quantum fluctuations. Do the particle (and its' anti-particle) appear from nothing? I know it happens in a Quantum vacuum. But do the particles themselves appear from nothing? Where do they get their energy...
