I'm not talking about practically predictable using current tech, I'm talking about theoretically predictable. Everything that happens can be theoretically derived from the laws of the universe. The laws are deterministic (perhaps except for quantum mechanics). Therefore, everything is deterministic and can be predicted. Human emotions are only unpredictable because we don't have an accurate model of the brain of the human we're trying to predict. If we did, and had a computer powerful enough to simulate it, their behaviour could be predicted. Hence - lack of data (model of the brain) and processing power (computer to simulate it).

Also chaos theory has nothing to do with the possibility of predictions, only the difficulty. It states that a chaotic system yields very different results for very small differences in initial conditions, not that there is some magic randomness that is impossible to account for in the system. Given the complete initial conditions, you can compute it completely deterministically. Therefore, if you get it wrong because of a chaotic system, it was lack of data (the incorrect initial conditions).

They are called theoretical for a reason and reason is that its not proven yet hence has no basis in reality unless it can be proven with experiment.

I believe there is absolute randomness in universe, contrary to popular believe that everything is predictable but i do respect your opinion. Thanks for sharing.

Not exactly, in this case it's theoretical because it is not of practical concern, despite being true. A theory in science is the highest possible status an idea can achieve, nothing can be conclusively proven.

Quantum randomness is a pretty popular idea, but everything else is known to be deterministic. Whether the universe as a whole is random or deterministic depends on if quantum randomness is actually true randomness, maybe we'll have an answer in the coming decades.

As far as I know, determinism is a philosophical idea not an established fact and theory is what it is, just a theory. Just because it isn’t possible to prove it doesnt mean that we will blindly trust it. Theories exist on both side of arguments, even free will to some extent negates the idea of determinism completely.

This is a conclusion drawn backwards, I think. If determinism is the evidence we have, then it is determinism that negates the idea of free will. Free will is an illusion.

Like i said its a philosophical debate not an absolute one. Idea of free will has not been rejected and wont ever be in my opinion. You could be right or you could be wrong, we will never know as long as people on both sides of the argument live :)

I have learnt a-lot from this debate though so thanks a-lot for your time and valuable feedback.

Determinism can be deduced from the laws of physics - if the laws are deterministic, then the universe is, by necessity, also deterministic. But there are many strange things we don't yet know about, such as consciousness and free will. So, no one really knows. Good talk!
