Thanks for posting this OP, it actually means a lot to see someone talking about this.
I’ve been very lucky in that my pain has responded really well to medication, but I’ll never forget how absolutely awful it felt to be physically unable to play the games I love. I hope we continue to push for accessible features in games more and more, this is a great hobby and when you’re trapped at home it can have an enormous impact on your quality of life. Even just the social aspect of gaming is a huge benefit.
Well, data just doesn’t really flow at the speed of light. It’s a really really complicated thing to discuss in terms of physical circuits because the true picture involves considering how the EM field evolves. Electrons in a circuit move at extremely slow speeds, ~millimeters per second.
The good news is you don’t need to send information particularly fast to send it through time. Generally in physics, we build time travel systems by creating extremely curved spacetime that contains paths to the past, theoretically you could send light through such a path to transmit information back in time. As someone already mentioned, you generally need negative mass to construct these.
If you have negative mass there are three options I’m aware of:
If you want to send information into the distant future, you could get really fancy and scatter some light off of a black hole or something.
