This is kinda Matrixy, can you rap your head around it ?
Concept.
Building a computer model of the universe that is 100% accurate.
Ok, to make a model that is 100% accurate it would have to account for every single atom that is in the universe. It would have to have information on the position, speed, direction of every single atom; it would also have to have information on how that atom is related to another. Ie. Is it an atom in a water molecule, it would then have to have information on that water molecule and its behaviors.
Now if one were to consider the amount of physical storage required, for every single atom even the best storage device would require thousands of atoms just to contain the information on 1 atom.
Therefore the computer would have to be 1000’s of times larger than the universe itself, and as the universe is expanding, although there is no new matter being added, because it is expanding position coordinates of new empty space would all have to be accounted for.
Now before one argues the uncertainty principle, or quantum physics and that analyzing the state of matter would change its state.
We can assume that if we were capable of building such a computer we would have resolved these issues.
So now having this computer and model of the universe and everything in it, I could look at you like you I was playing the Sims. I could fast forward and see what you do tomorrow, or rewind to when you were born.
So, today I fast forward the computer a day and see you trying to make a decision on what you want for lunch tomorrow, KFC or Mac Donald’s…. You pick KFC….
Now tomorrow comes and you’re standing there trying to decide what you want for lunch, but I have already seen that you pick KFC.
So from your point of view you have a choice, but from my point of view you don’t, I already know your going to have KFC.
Now if you had a choice it would be a 50/50 chance…. But as I know for 100% you’re going to pick KFC, that means you have no choice.
From the instance of the big bang you were destined to have KFC for lunch on that day.
Now…. Just because we don’t have the computer to fast forward our universe simulation to tomorrow, it wouldn’t change the fact that tomorrow you are going to have KFC for lunch.
My point, to us it seems that we have a choice, but we don’t…. Our whole lives have been pre determined from the moment of the big bang.
So, the next time you are trying to decide if you want KFC or Mac Donald’s for lunch, stop wasting your F#*%en time, what you are going to have, was determined billions of years ago !
