*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.

These comics seem to age surprisingly well.

The idea is checking out with more than a basket of goods is really inconvenient. And I agree, it's much slower and there's no space for it.

Paladin: It works because I just feel really strongly about it.

The more we know about this, the better. Depressing as it may be, learning about these means eventually we may be able to revive them.

It all depends on what you mean by affect. Two em waves in the same space will have a different overall amplitude at any frequency.

If you mean as in the overall color of light, that will change based on how much/what frequency waves are combined. Think about adding a bit of black sand to a jar of white sand -- from a distance it will appear grey but the actual colors of individual grains of sand (frequency of "individual" em waves) won't change.

For wifi, data transmission is via phase modulation of the em wave, so the signal is resilient against adding different frequencies/amplitudes but may suffer if the same frequency is transmitted at a different phase.

Birth rate decreasing isn't a problem, it's a symptom of declining quality of life/access to resources.

Instead of unsustainably adding more people maybe we should worry about the damage an obsession with growth+profit does to the climate and social structure.

Oh yeah the hate speech is legal, it's just the hanging of the sign on public property that isn't.

Even accounting for power plants, EVs still produce much less emissions. Here's a plot from energy.gov:

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.
