Probably not, but colonizing other galaxies without it is extremely complex. The closest one is 2.5M ly away, so it'd be over 2.5M years just to get there.

- flukus 10y agoIf you could get to .99c then the onboard travel time would "only" be ~200k years. Something like cryogenics and it could effectively be 0 years. The jump to intergalactic seems much smaller than the jump to interstellar.
- hobarrera 10y agoDude, not sure what sort of math you dud: 2.5M * 0.99 = 2.47M. It's 2.47 millon years, not "~200k". How would you do 2.5M light years in ten times LESS than 2.5M years without FTL? cryogenics does not alter the time it takes to colonize galaxies -- it just seems less to the person travelling, but that's irrelevant in this context, since we care about people NOT travelling (eg: us).
- flukus 10y agoRelativistic time dilation. It will take 2.5 million years to an outside observer, but ~200k to those on board.
