I have thought about this in the past a few times. Let's say we can simulate the universe with a powerful computer in a room. The resources for processing and storage would be impossible.
Let's say that this computer has massive hard drives that stores all the information of the universe. This would be unrealistic if you want to keep track of every atom in the universe. Even if you used really good compression algorithms, it doesn't matter.
To simulate the universe, the computer would also need to simulate itself and its storage. What if there was a room of a 100 of these computers each running simulations of the universe? The recursion would be never ending and a piece of hardware can not even fully simulate itself plus much more.
