Where’s the computer
that runs the universe?
Notes

I’ve been running simulations of our universe, according to Stephen Wolfram’s computational theory of physics.

Where’s the computer that runs these simulations?

Well, it’s right here. This a low-powered laptop in my hand is literally the computer that runs these universes.

It’s natural to ask a follow-up question.

If Wolfram’s right and the real universe evolves computationally in the same way as these simulated universes, where’s the computer that runs the universe?
