The trumpets have sounded, the simulation hypothesis, the idea that we are all living in a simulation of our universe created by our distant descendants living in the “real” universe, is dead.

In a new paper, Italian physicist Franco Vazza, a researcher in astrophysics simulations, claims that it is impossible to simulate even a sizeable portion of the universe within itself.

This conclusion seems intuitively obvious. While the universe may be bigger on the inside, it doesn’t seem like you should be able to represent the whole thing inside itself.
