Faster than light speed, what a dreamy term.
This was also a problem that all civilizations had to face after entering interstellar space. When they wanted to go to other galaxies, the travel time of several years, even hundreds or thousands of years was enough to make everyone shrink back.
Perhaps some civilizations would use hibernation technology as a replacement, but this was only a temporary solution. Not every galaxy in the universe was habitable. What if the nearest habitable planet was thousands of light-years away?
Decades of hibernation were enough to make a person lose contact with civilization. After a thousand years, their civilization might have been destroyed by some drastic change.
It could be said that if one wanted to develop in space, faster than light speed was a high wall that could not be bypassed. Only by crossing this obstacle could one have the possibility of going further.
