Basically I want to know the validity of the statement, "All randomness originates from wave function collapse" or maybe "The only true random event is the collapse of wavefunctions"
This seemed to jive with me initially, but then I thought about the random fluctuations in underlying quantum fields, as well as the idea that the quantum fluctuations at the big bang combined with hyperinflation may have caused the uneven distribution of matter we see today. Those effects aren't due to wave function collapse, right?
Are there more sources of randomness? Is there a general statement we can make about randomness and where it physically originates from?
