I have an ongoing bet with a buddy. I win when the Space Force establishes a base off-planet. He wins if the US forms a Time Force branch. Neither of us expect to win in our lifetime.
My money is on your buddy. The most likely scenario there is, is that Trump around New Year's Eve forgets how time zones work and thinks that China is in the future which leads to him founding the Time Force. And all they can do is travel to the future, at a speed of 60 minutes per hour.
Or more likely, they build a base directly on a time zone line so they can jump between the zones going "4 o'clock, 5 o'clock, 4 o'clock, 5 o'clock..."
I want to say we agreed that the base had to be out of Earth's orbit. I'd have to go over the details again as we made the wager a long time ago and after several drinks.
Does a moon base count? Technically the moon would have orbital priority but it itself or its the Earth. Does an aldrin cycler count as a base? Does something in an unstable orbit that happens to largely coincide with earths orbit count?
No on the moon base as the Nazis already did it. The base needs to be installed on a terrestrial body other than Earth and its moon. Just to keep things fair since we're unsure how long it might be before the fabric of time is discovered to require military intervention.
Thats a meaningless distintion, the moon orbits the earth with an elliptical orbit in the Earth's frame of reference, or an eliptical orbit with fairly large, low frequency oscillations in the Sun's frame of reference. The same is true for something in LEO except the oscilations are smaller and shorter period.
I think your buddy is most likely to get the money at least. You'll be dead before yours is true, but if we need a Time Force, your buddy may still get his money. It might be created in 1000 years, but someone may let him know he won and get it to him.
WHEN we need a Time Force they'll probably have travel locked down so it's unlikely someone would make it back to deliver the news. Might have to add a rule about not disrupting the time continuum and just let descendents claim the reward.
