Our world can’t be simulated using the current storage and computing limitations. But we can restrict the variables to be able to predict 99.99% of the time.
What I mean is - predict where the basketball will bounce - you need force, direction, ground even-ness, wind, other vibrations, moisture etc. - not too many.
But predicting larger scale - nope, not right now
But if our world is a simulation, then there exists a computer capable of runnig our world’s simulation.
So all we need to do is figure out how to hack into THAT computer, and then we can create any kind of world we want.
I look at it as trying to break the speed of light. Even at 99.99%, almost infinite energy and mass of whatever is trying to get to that speed.
for such a device, it would have to have the power of the sun to draw on and storage and process would require something as large to exist on as the world it was trying to sim....IMHO.
To take in and process every variable to me is impossible. Not to mention the amount of programmers required to make the damned thing work.
