Hypothetically, science proves free will isn't real

You're overcomplicating things hugely. It's not necessary to talk about other possible determined universes, we are talking about the universe we do live in and are asking if it is predetermined, and then asking what that says about free will. There is a reason that the philosophy debate falls into four positions: Hard Determinism, Soft Determinism/Compatabilism, Libertarian Incompatabilism and Hard Incompatabilism

Unless you agree these are the four possibilities regarding "free will" we are at an impasse:

1. There is at any given moment one physically possible future in this universe and for this reason we don't have free will. (Hard Determinism)
2. There is at any given moment one physically possible future in this universe but we still have free will. (Soft Determinism/Compatabilism)
3. There is more than one physically possible future in this universe and for this reason we have free will. (Libertarianism Incompatabilism)
4. There is perhaps more than one physically possible future in this universe but we still don't have free will. (Hard Incompatabilism)

I'm a Hard Incompatabilist. But I believe this world is determined, and I take the hard rather than soft determinist position.
