If we could manage to build a spacecraft that could continuously accelerate at 1g. It would, from the perspective of the inhabitants on the ship, be possible to travel to the end of the edge of the visible universe and back in 100 years, even though billions of years would have passed on earth. Relativity is weird.

note that a spacecraft which can continuously accelerate at 1g would require an insane amount of energy. Relativity is indeed weird.
