Greetings, everyone, and to all of my colleagues from the attack on the Children of Entropy base, congratulations and my personal thanks for helping to save, among other things, my own world.
I've a technical question about time travel. I'd like to know how it works in your respective worlds, if it does at all; what devices enable it, whether or not the flow of history can be altered, what restrictions have been placed on it, and anything about how the arrow of time can generally operate.
It's well-known in my universe, after all, that a universe in which electromagnetic charge, the parity of particles, and the direction of time are all reversed is identical to our current universe. This means that every theoretical violation of time symmetry is accompanied by a proportionate violation of charge and parity symmetries -- CP violations, for short. I regret my understanding of physics may not be deep enough to truly understand the full implications, but I'd love to hear what you all think.
