Hypothesized civilizations like class 4 and above on the Kardashev scale could potentially just cut out a part of the cosmos and move it closer if the travel distance was an issue. Or temporarily just freeze time.
You break cause and effect this way. Worm holes = time travel. Their energy requirements are insane and their designs tend to involve exotic matter that doesn’t exist.
It would involve new understandings of physics to figure out shortcuts.
The time issue isn’t even the biggest hurdle. (Though it is a big one) at 80% the speed of light humans can spread out to the stars. hundreds/thousands of years pass on earth but only decades to the traveler.
The big problem is running into dust. Space is actually really rich with material. a spec of dust would blow up a space ship at those speeds.
Radiation from stars, bodies withering from so much time away from gravity. Artificial gravity machines would be necessary and would involve lots of energy with lots of moving parts that would wear out.
Pretty sure we are closer to the last ice age than we are to interstellar travel.
Considering an hypothesized level 5 civilization is harnessing the energy of several universes, the energy requirement is not an issue. Would an hypothesized pause in time, or shifting around mega-masses of matter break physics as we know it? Yes. But going back to my argument about humanity’s limited knowledge, I won’t hold the unknown to our known or perceived standards.
Merely understanding a very common and accepted phenomena like UFO’s requires a new understanding of the universe just when it comes to whatever propulsion UFO’s are using as well, no matter if it’s anti-gravity engines or happy thoughts and fairy dust. And that’s just assuming they’re crafts with exotic technology. The truth might be vastly more bizarre.
I see how dust would be an issue to a kinetically driven spacecraft, but since I believe the most probable mode of currently existing interstellar travel is based on gravitational engines that envelops the passengers in a separate gravitational bubble I’d think it would be possible to use the same technology to create a sort of space debris shield.
Pretty sure we are closer to the last ice age than we are to interstellar travel.
I don’t think so, I just don’t think we’re allowed to know how close we are. I know that’s a thought as crazy as saying the vaccines aren’t safe and effective.
