Questions about Time, Distance, and Relativity

A thought experiment:

run a string from here to the Andromeda galaxy (2 million light years m/l)

put a knot in the string every mile.

fly along side the string at .999whateverC relative to us stationary along side the string. To you, on the spacecraft, counting knots as they go by for an hour, you will note relative to YOU, that you're traveling at an extremely large multiple of the speed of light, and going "WTF?, I thought faster than light was impossible !!!"


If you get to the Andromeda galaxy in 20 years (thanks to time dilation), your speed you measured was 100,000 times the speed of light. To us stuck at home, however, it really did take you 2 million years to get there.

Le me:

It all makes sense now.
