Hypothetically, science proves free will isn't real

Personally I don't think it's possible to demonstrate that there either is or isn't any kind of alternatives at any given point. Not when we're stuck in the middle of what is effectively one data point.

We would need to be "outside", with several identical versions of our reality, so we could actually test things. From our point of view that is probably forever impossible, but even if we do get outside, we have the same problem regarding wherever the hell else we are after that.
