Yeesh I’m just not good at that kind of stuff. Time dialation is what is making this hard for me to wrap my head around, but basically the big issue with this method of travel is you need infinite energy (which might be something these ships somehow do) and its like fast forwarding into the future, so even if you go back immediately it will be like you were gone ~18 years but only experience less than 2.
It is certainly an interesting thing to think about, but sounds depressing in practice. If this is the practical way that some beings have traveled here, I feel like we are missing a piece of the puzzle for long distance space travel. Maybe they have a way to do something about time dilation. Or maybe they just don’t ever die…
Ah, I misread a wiki page. Not infinite, since we aren’t traveling lightspeed, but approaching infinite as we approach lightspeed? Which is to say, not infinite but dang thats a lot of energy?
Again, I’m not great at understanding this stuff, so thanks for being patient
