Question

If you are traveling on a spaceship close to the speed of light (pick a number e.g. 0.95c), With or without constant acceleration whichever works for the question.
Time will slow down relative to earth and you will be able to travel a greater distance than you would be able to without relativistic effects. You would also be able to return to earth with significant time passed relative to your experience.
My question is, what would it feel like on the spaceship...I know the standard answer is you wouldn't feel anything, but logically, if you were traveling through galaxy after galaxy in a relativistic time of human life then intuition says everything would look like it whizzing past.
Basically, what is the human experience of being able to travel interstellar distances?

Answer 1

Of course, everything is whizzing past compared with what it would look
like if you were at rest relative to the earth. What you
would also see is that the distance to an object you were
moving toward is shorter by a factor of (1-0.952)=0.31;
so if you went to a star 1 light year from earth, it would
only take you 0.31/0.95=0.33 years to get there but the
earth-bound clock would say it took you 1/0.95=1.05 years.
Also where the stars appear to be relative to where they
would be if you were not moving would be different; see an
. In the case where v/c=0.95, the graph shows
how the angle at which you see something depends on where it
would be if you were at rest; for example, a star actually
at=1200 (300
behind you) would be seen as being about '300
in front of you!
