I once did the calculation. If you accelerate at a lovely 9.81 m/s^2 you reach light speed in about a year or so. So if you time it right and decelerate with the same rate you can reach about any place in the nearby universe in about two years.
Just need to figure out this pesky energy problem. And hopefully not collide with cosmic rays on the way.
And to time it right, you need to either not reach light speed, or have some external help to decelerate. Every clock or circuitry you bring with you also slows to a halt
I mean it depends on how you reach the speed of light. Straight up propulsion correct but then you cant get the energy required for that, if we can somehow figure out a way to bend space to create a “warp” bubble the internal zone should act as we expect, but the energy requirements there are still fucking enormous and im not sure that would be feasible without us inadvertently creating a singularity that we could never escape from so there are just problems inherently there for either method lol
If you do use a warp bubble (we’d need to figure out negative mass, which likely doesn’t exist), your local time will not dilate nearly as much, so the subjective time for the traveling observer might actually be a lot longer
From a certain point of view.
If you are fast enough, certaunly you experience few time in the journey, only for the observer on Earth it last a lot of years.

They forgot about time it takes to accelerate…

Your comment reminded me of that one dude in The Expanse who tried to slingshot through the gate…
a mind blowing experience

Well then you are lost.
