So I was day dreaming and I caught a thought. What if what we understand about physics is actually all there is to understand? What if you objectively cannot move faster than the speed of light because you can’t do the time traveling things necessary. This would mean that the only way to travel amongst the stars would be to extend our lives so that a 5000 year trip at the speed of light would represent like 10% of our lifespans. Travel would be attainable but like the way it was when we were sailing ships to the new world.

That’s just one practical solution I could think of to stellar travel. Does anyone else have a practical idea?

      No, the only limit to everything in our lives and in the universe in general is… Energy! Energy is the real currency of the world.

      Nah, it’s actually super hard to maintain that acceleration. Not to mention all the fun of radiation, avoiding random obstacles and I assume the interstellar medium will become more dense to an accelerated observer.

      We have idea on how to do it, but the engineering is far from it yet.

      That, and figuring out how to travel even just a significant fraction of the speed of light.
