Maybe there’s a way to find out if reality is a computer simulation
Randomness
In olden days, before the Star Trek holodeck and movies like TRON and The Matrix, philosophers used to wonder whether life was but a dream. Nowadays they’re more concerned that reality could be just a computer simulation.
Sure, that’s not very likely. But you can’t rule out the possibility. Computers simulate all sorts of things, and some scientists have seriously suggested that nature’s supposedly rock-solid reality is really just some smart alien teenager’s science fair project.
