If the human race eventually finds a way to travel at a significant percentage of the speed of light and space travel becomes somewhat routine, how could the time dilation be taken into affect between various journey points.

How traverse the changes of time , language and future technologies and bridging those gaps and also loss of family members and separation of literal time in years would be an emotional decision for or against using the travel option. I imagine this will be the reason why some people opt to walk away from technology , whilst some will embrace it.

Yes society would change almost beyond recognition and you’d need some sort of organisation that can survive this long almost quasi-religious in nature to welcome this people back into the fold and have some understanding of whom they are/were

C J Cherryh (in better books) and William Rottsler (in The far frontier) talk sensibly about the consequences of that. Most SciFi authors don’t.

Yes, time dilation causes all sorts of family mix-ups. Husbands lose their wives, boss and junior swap roles. News of the progress of a war doesn’t get back to the loser. Commandos suddenly find that their quarry is fully prepared for their arrival. When combined with suspended animation, a person may find themselves to be older than their great great grandparent.

Technology takes time to catch up. Finance becomes a problem in waiting for returns on a space venture. Unscrupulous individuals steal wealth and disappear before anyone else can find out. Politics becomes almost irrelevant because the timescale of politics is too short.

Combined with our quite short life spans as well

Gene Roddenberry and the creators of Star Trek were dreamers, they had knowledge of the problems and they imagined the solutions, Warp Drives, sub-space communications, acceleration dampers etc.
They fit Bernard Shaw’s quote “Some men see things as they are and ask why, others dream things that never were and ask why not.”
It’s the dreamers who will shape our destiny, the movers and shakers will make the dreams come true.

Perhaps the best sci-fi book with time dilation as one of the major themes has to be Haldeman’s “The Forever War”. Classic.

the energy source to power this type of travel needs to be solved as well.

Yes. I tried all three of nuclear fusion, antimatter, and black hole drive and couldn’t get any craft up to high sublight speeds. That was annoying.

The forever war. Good one.

If high sublight speeds are possible then travel to the centre of the Milky Way is possible. But travel to another galaxy would still be out of reach.

The sort of space travel you are describing would be good for travel within the solar system and that’s about it. Anything short of FTL travel isn’t going to work very well over even interstellar distances.

Totally wrong. You’re forgetting Fitzgerald contraction. With Fitzgerald contraction it is trivially easy to travel 10 light years in 1 year at sublight speeds because distances are compressed in the direction of travel. The distance to the centre of the Milky Way is 100,000 light years, so with a factor of 100 from Fitzgerald contraction that would be traversible in 1,000 years. Which is not too long a time, shipboard, especially if taken in 20 steps of 50 years each.

Kind of like time travel, people upload themselves to a chip, in VR they go to sleep, next they wake up on a remote planet millions of years into the future.

Marvin the depressed robot looks after them on the journey.

That’s what I call a Stage 3. It needs a remote planet with macroscopic life on it to work. But it does allow greater distance than Stage 2.

I prefer Stage 2. Stage 2 doesn’t even need a planet, a remote body similar to Titan or perhaps Pluto would suffice.
