"Randomness does not exist."

Backstory: I'm taking this deductive logic course centered around a theory called Information Measurement Theory developed by the professor who heads a research group. I'm concerned this will turn out to be a pseudoscientific philosophy course, especially after today. Topics discussed today about the theory were: -Randomness does not exist -It is not possible to control others -It is not possible to influence others -A person defines his/her environment, while simultaneously, the environment defines the person -No person can know all information So I ended up getting into an argument with the prof, the TA, and half of the class about randomness. I argued that randomness does exist, or at minimum, it's arrogant and naive to presume to know that the universe is deterministic. This seems especially true given their fifth theorem that no person can know all information. Examples I cited were dice, queuing theory, radioactive decay, and Heisenberg's Uncertainty Principle. Dice and queuing theory are not what one would call "truly random", in the sense that with enough information, one could deterministically predict the outcome with certainty. However, Heisenberg's Uncertainty Principle is impossible to refute without finding some way to expand quantum mechanics to a universal scale. Wave function collapse caused by external mechanisms can only be prevented if nothing in existence is external to the system being observed. So while it's possible that every event is deterministic, that would require knowledge of all things, which is directly contradictory to their fifth theorem. Anyways, I'd like to hear what you think about this "theory" of theirs, the various theorems, and about randomness.

  • [quote]Wavefront collapse caused by external mechanisms can only be prevented if nothing in existence is external to the system being observed. [/quote]*Wave function collapse Actually it can be prevented by not measuring it with current methods. The only reason it collapses is because we measure it with photons which are on a similar scale so it causes significant disruption to the system when it interacts. If we were to find some way of measuring without messing things up like that then we'd be good, I doubt that will happen though. Point is that it's nothing to do with the fact that an observer exists, more to do with the fact that the only method of observation we have involves knocking the system into disarray.
