The real world.
You can predict the future with 100% accuracy by determining the conductive properties of all atoms and molecules on earth so you will be able to predict where energy will travel to next. The future is corporate satellites scanning Earth's atomic and molecular make up and reading energy from space and earth and creating a computer simulation that predicts exactly how all energy will transfer from object to object, essentially predicting all motion that will ever happen for the rest of time before it happens in the real world.
Sounds like a lot of work. To what profit?
Reality is multiplanar, your simulation will only include material plane and only the parts capable of being scanned.
