We had the discussion about the B-Theory of time and the "four dimensionality" theory is very, very similar.
Essentially, it says something like that the universe and all objects in it are "4D objects", with the space-time being the 4th axis. One interpretation is that "the consciousness moves along the 4th axis", thus creating what we perceive as causality/time
I come to realize that this theory is sort of...frightening, since it implies (to me) that all events, "past", "present" and "future" are already pre-set on this 4th space-time axis in an universe that is a giant "4D object". Any event, whether past or future is already set and established. Things don't actually "happen".
The frightening thought is when we use an allegory of a movie or record player. At ANY point of the movie (or the record), this is what we call "the present", and what lies ahead we call "the future", which is not known to us. YET, obviously everything is already set in stone. In this theory, free will is literally an illusion which is merely coming from the fact "that we don't know what lies ahead".
To illustrate:
Say we're able at some point to build a time-machine. On September 6th, 1991 you made some choice, example you visited an ice cream shop and chose between their 30 flavours. You choose Strawberry, Vanilla and Peach. Because you have "free will", allright.
You enter your time machine and travel back to that exact date on the space-time axis in the 4D universe, in the same way as you would rewind a movie or place the needle of a record player back a few notches.
You (or: The universe) would experience again the scenario in the ice cream shop, and you would again choose Strawberry, Vanilla and Peach....and you can do that 10000x times and you'd always do the exact same thing...and BELIEVE each time that you acted on "free will" of what in reality is already "imprinted in the universe".
It also doesn't matter where the "needle" of the record player is, whether the "future" is tomorrow, or whether you set the needle back to 1981 and then your future is 1982 etc.
This idea of the B-Theory of time and/or the 4-dimensionality would obviously also do away with any time-travel/grandfather etc. paradox. When you go "back in time", it will be EXACTLY like it was before, all the events, atoms etc. would be exactly the same. You cannot go back in time and make a new decision - you would be "literally" the same person in the same situation doing the same thing. I cannot "go back" to 9/11 to NYC to help prevent 9/11 since I was in Chicago on 9/11. I'd find myself again watching TV.
Obviously, what happens tomorrow is also already "imprinted", there is already information in the 4D universe whether we win the Powerball or whether the sun shines tomorrow or not...and everything else. So doesn't really leave any space for free will in this scenario.
Free Will - an illusion "created" by the brain...in an universe where everything is pre-determined?
