Philosophy Of The Cosmos - Possible Paradox
I was thinking about the take on quantum mechanics after reading all of Kathryn's posts. One thing occured to me.
From the copenhagen 'version' in my understanding, something does not exist if it is not being measured (or is it that you dont need to worry about it?) If it does not exist, how would the universe 'evolve' to such a piont that life could be created? If there was no life to measure the universe, there could be no universe to create the life.
I could be wrong and have misinterprited this point.

First of all, to answer your question, people don't really agree about exactly what the Copenhagen interpretation says (my lectures are mostly about the bits they agree about, ignoring the bits they don't agree about), but I think it's meant to be more like you're not meant to worry about it rather than it doesn't exist (when something's not being measured).
As for your main point, the answer is meant to be in the maths. I don't think there's a satisfactory explanation in ordinary language. It's just, well, the Schr'dinger equation tells us what happens based on the Big Bang, regardless of whether any of it is real … and then one day (maybe, according to Copenhagen) it gets collapsed by the Born Rule. Does that make sense? Maybe not!
There IS a theory that it's the existence of conscious life that RETROSPECTIVELY creates the universe. This is a bit like the anthropic principle but not quite the same. It was invented by John Wheeler. It's not a very popular theory, but I can't find any particular flaw in it. It could be right.
