Are we all just part of a computer simulation? Scientists are trying to find that out.

"The universe is made of bits. Every molecule, atom, and elementary particle registers bits of information. Every interaction between those pieces of the universe processes that information by altering those bits. That is, the universe computes, and because the universe is governed by the laws of quantum mechanics, it computes in an intrinsically quantum-mechanical fashion; its bits are quantum bits. The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is analogous to a quantum computer." (Lloyd, 3)

There. Fixed that for him.

Lol ... but see, the author wrote that because he believes that the universe being a computer is not just an analogy, but it is a computer ... a really big one.

He also argues that it is impossible to simulate the universe. Why?

Because in order to simulate the universe, the simulation would require the computational capacity of the entire universe itself, and it would have to be the size of the universe itself, which is impossible.

I've posted below a video of an interesting panel discussion where four scientists along with Seth Lloyd, the author of the passage quoted above, talk about this whole "universe is a computer" idea, and why it could be true.
