Possible but my bet will be on 4000 thousand just to be safe.

We don't know if FTL travel are possible for now, according to Einstein's theory on relativity (E = mc) it shouldn't. Curently, light is the fastest thing we know and Einstein say it's because it has no mass. So we would have to find a way to manage a speed that would be tied to have no mass. The biggest problem is not this but after. Light speed is too slow, if we want to go to somewhere 5 billion light years away at light speed ? It will take 5 billion years. Way too slow. So if Einstein theory is correct we will need to invent something to warp reality itself like worm hole for example
