*You can only teleport out to where you teleported in from.

Does this mean you get dropped into outer space if you stay inside for more than checks notes ~4 minutes?

Is it feasible? Sure. The limit on this kind of calculation is basically how much detail do we need to add to the environment (i.e., can we make the model) and how high resolution does the sound wave need to be (can we calculate it given finite compute resources).

To get something that roughly sounds like a rock? Not difficult to model or calculate, if we make some reasonable assumptions.

The sound of a wet towel thrown in the water during a hailstorm? Uhhh that’s a tough one.

Simulating sound uses classical mechanics governed by the wave equation, which is well-understood. In terms of CPU power, the calculation to propagate a simple sound wave (wavelet) could probably have been done on a TI-89 calculator from high school.

How about an app that makes calls, but you have to dial like you would with an old rotary phone.

If you make a mistake with the rotations it just connects you to a random one of your contacts.
