does this open the door to possibly traveling back in time?
It's impossible to tell, as that can cause other issues. See the link I posted about time travel elsewhere in the thread.
Does this mean time travel is possible ?
no such thing as backwards time travel, sorry!
Wouldn't that prevent time from going in reverse?
I think you’re describing this? https://en.m.wikipedia.org/wiki/Novikov_self-consistency_pri...
Only one-way interaction between different selves? And you call this time travel.
"If time travel is possible, then there is no such thing as time."—Kurt Gödel
You're right however this isn't possible with our current understanding of time: https://en.wikipedia.org/wiki/Spacetime
FTL implies time travel. The into-the-past kind. Good luck with that.
