We should go 4D and start dissipating heat into the past.

Wait... global warming... shakes fist at the future

Sometimes I daydream about what would happen if FTL communications were possible, but only over short millimeters. It’d seem useless right?

Until someone figured out how to put it in chips! Faster processing and memory.

Also there would be a poetry to FTL via quantum entanglement being possible only as a speculative “guess”, similar to specter but on the quantum hardware of the universe. Sure FTL signals might be impossible but guessing at FTL signals might not be. ;)

this is already a thing

Alas, virtual particles appear to travel FTL, communication isn't possible with them:

The idea of a time travel loop in the processor reminds me of a talk by Damian Conway, in which he shows how avant-garde Perl code to exploit sci-fi hardware.

Ah, that's how the ice age ended

Well, the Earth was in a different point in space in the past, so it would not end up on Earth.

Interesting idea, although if true then time travelling even a second earlier/later would likely put you several hundred km in the sky (or the ground). I guess any potential time travelling device would have a reference point located in itself, therefore prohibiting this effect.

Sort of the opposite to what we do with CO2 production at the moment?
