So, here’s the deal: You’ve managed to acquire the data, but disaster strikes, and your time machine is destroyed by an enemy time traveler team. This is crucial historical data that you’ll have to get into the future to avert the apocalypse. Due to the constraints of the space-time continuum, all time travelers staying outside of their “home” time for longer than 1 year will die, so you have exactly 1 year to prepare. How do you make sure the future discovers the data, while preventing the enemy time traveler faction from stealing the data?
(Remember: don’t just chuck it in a hard drive and bury it in a forest somewhere, the data will degrade)
No, it doesn’t matter. There are infinite good and bad guys. They all can spawn a second before each other until the big bang. You can assume the friendlies aren’t complete morons and have set up some encrypted comms, although presumably that itself is in its own time loop of decryption and re-encryption itself, since you effectively have infinite time to both track down and decrypt any code.
The real answer is time travel makes no sense.
The real answer is that time travel to the past is never possible.
