A very simple philosophical question that can trigger an existential crisis. Do not sue me if you do get an existential crisis, that was probably a pre-determined event… or is it?

I mean I personally don’t see why the universe is non-deterministic, every time you flip a coin, or roll a dice, if you knew the initial conditions and the forces applied to the coin/dice, the atmosphere, wind, etc., you could predict the results with absolute certainty. And free will does not exist. But that’s just my view on this matter, who knows what the universe really is.
Indeterministic + free-will doesn’t exist and can’t exist. You literally end in impossible contradictions if you entail its existence in a consistent universe (as in, one where everything that exists is subjected to the same natural laws).
As a side note for OP, Hisenberg has proven there’s no such thing as “knowing the initial condition”.
