What if the world is simulated?

Imagine a brain receiving every sight, sound, touch, and consequence from a simulation.

Philosophers call this the brain in a vat thought experiment. It asks what a person could know if a computer produced every experience they received. If you've seen , the setup may feel familiar.

The simulated world would still have to answer back. Turn your head and the view must change. Drop a glass and it must fall. Make a choice and something must happen next.

Must meaningful experience come from a physical world? Or could a responsive simulated world provide enough experience, action, and feedback?

The thought experiment does not answer this. It shows that "connected to a world" raises another question: what kind of world?
