Again, relativistic speeds change distance (from what we experience at non-relativistic speeds). At no point do you travel faster than light - the world you are leaving will appear redshifted. If you were going faster than light, the background would simply disappear, as its photons would not reach you (yet).
- somenameforme 27d agoAh I see what you're arguing! Yes you're certainly correct, that you will not measurably perceive yourself traveling faster than light as the universe will contort itself endlessly to ensure that doesn't happen. I'm imprecisely speaking of your distance/time relative to a fixed point at rest if you yourself were at rest as well.
- gowld 25d agoNothing can be observed travelling faster that speed of light in the observer's proper time, but many things can be observed having travelled faster than the speed of light, when considering the traveler's proper time and the traveler's observation of distance before and after the journey.
- somenameforme 25d agoYip, I think we're all saying the same thing, but with varying degrees of unspoken assumptions on a topic where we all, generally wisely, think other people have no idea what they're talking about.
