One possibility is that from an omniscient perspective, free will is indeed meaningless. But then again it can be argued that everything would be meaningless from an omniscient perspective: time, space, matter, energy, freedom, love, whatever

That is unless there is some sort of actual absolute meaning to the universe, which is a very boring and treacherous line of reasoning that i won't entertain here

However he existence of an omniscient entity would completely break physics as we know it so any physicalist/rationalist approch to understanding the universe can fairly safely rule it out

Free will may exist as a result of the unknown factors of human consciousness, their actions and consequences and their relations to the physicial world.

Personally I find that thought quite pleasant, because it means that free will does exist from a human perspective, and I happen to posess one of those.
