The debate continues among quantum physicists about whether the universe could be a simulation, particularly in relation to black holes and information theory, especially since the total amount of information in the universe is finite, meaning all possible universes can be summarized in a calculable number.

The universe is efficient, and there are two reasons why I believe it is not a simulation: the incredible computational numbers involved and the question of why a superintelligent being would simulate humans, who often act irrationally.

The idea that we live in a simulation doesn't add anything meaningful; the laws of nature themselves can be seen as a computer program that governs our reality.

The idea of being in a simulation raises questions about consciousness and the nature of reality, which are complex and not easily answered.

If a computer could simulate the finite amount of information in the universe, then it would imply that our universe is a simulation.

I don't think we're in a straightforward simulation, but I do believe that underlying physics is rooted in information theory.

The simulation theory posits that we may be living in a virtual reality, where our perception of reality is influenced by observation.

The mathematics of quantum mechanics is straightforward, but interpreting what those calculations mean for the nature of reality is complex.

The idea that a quantum computer would be powerful was emphasized over 30 years ago by Richard Feynman, who believed that nature is quantum mechanical and that simulating nature should also be quantum mechanical.
