If a length contraction is true, why won't all mass gravitate towards you
.... wouldn't Bob measure the distance to Andromeda to be the same (at the start of the journey) because as length contracts, so time dilates and the distance remains the same. (To keep c constant.)
Bob in his local reference frame would not notice length contraction or time dilation. Alice being a distant observer would.
If a length contraction is true, why won't all mass gravitate towards you, as you come infinitely close to lights speed in a vacuum (uniformly moving). You will find a lot of mass, very close to you.
However, Alice will measure that Bob only needs to travel 0.01*2.5 ly to get to Andromeda.
Who the **** is Mary?(With apologies to chubby)
Approaching light speed, distance contracts in the direction of travel. As distance in front of the space-ship contracts, does distance behind dilate?
