How to test if we're living in a computer simulation

There is some evidence suggesting that our physical reality could be a simulated virtual reality rather than an objective world that exists independently of the observer.

Astrophysicists have built the most detailed simulation of the Universe ever

The simulation consists of 18 simulations covering various scales - each a cubic mock-up of space up to 1 billion light years wide - tracing the evolution of the Universe from just after the Big Bang into the future.

Physicists Prove That Reality Is Not — Repeat, Not — a Computer Simulation

Mathematical roadblocks with quantum mechanics indicate that the so-called simulation hypothesis is impossible.
