The Universe Is Uncertain, Not Deterministic

Some people believe that the universe is deterministic, but this is not the case because we cannot simultaneously measure the velocity and location of quantum objects like photons. This is known as the Uncertainty Principle. Maybe the reason why instruments with perfect precision cannot exist in the first place is because uncertainty is part of the universe. The randomness introduced by measurements means that the universe is not deterministic. Additionally, there is no equation that can take into account every variable in the universe. Even if a hypothetical supercomputer existed and it were given near-infinite resources, it would not be able to simulate every event in the universe because the computer being part of the universe would also have to simulate itself recursively an infinite number of times. In any case, any entity capable of developing instruments with perfect precision, designing equations that account for every event in the universe, or building super computers with near-infinite resources to simulate the entire universe could be called God-like.

The universe cannot be simulated in its entirety due to lack of computational resources, due to lack of deterministic equations, and due to not knowing all the variables needed to plug into the equations. For example, how can you simulate the moon rotating around the earth if you do not know the exact distance between the moon and the earth? The simulation can only approximate reality because the measurement can only approximate reality.

Also, a perfect simulation is not possible if any information has been lost forever. For example, we do not know what happened before the big bang, so it is impossible to predict anything that could have existed before the big bang, so for practical purposes it can be said that nothing existed before the big bang.

Some information is lost forever and no mathematical formula or simulation can ever be used to regain the lost information. This is a very sad realization because most actions, words, and thoughts have not been recorded, meaning that for practical purposes it is like they never existed.
