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?

    But what about the bit about not hitting anything whilst travelling at that speed? Even a speck of space dust would do massive damage at those speeds, right?

      Oh yeah, it’s like flying the wrong way down the tube of the Large Hadron Collider. The tougher challenge though is like @[email protected] said maintaining 1G acceleration. Following the rocket equation, which is logarithmic, a 50 year multi-stage rocket will be bigger than the universe itself, even if you use some kind of nuclear propulsion 10000 times more efficient than our chemical rockets.
