Default TT maths



I would be grateful if someone would tell me how to work out when (Earth
date) one
would get back to earth if one went for an imaginary space expedition for x
years at y mph, e.g. 100 years travelling at 100 million mph. (own
time/velocity)

Thanks,

Hugo Pollak

A serious answer would be appreciated ! As I understand it, the direction
and route taken don't matter. If I travel at an average of 100 million
miles an hour, the answer should be the same (even if I have to avoid the
Vogon Destructor Fleet to get home) ! Is this not so ? I have a really
practical reason for wanting an answer to this question !

.... I think that will cover your need.

I am interested in how you think you will measure your speed...
Vogons, notwithstanding

Unless you want to actually get in your magical starship and travel at x
speed for y years etc etc away from the earth there really is no practical
need to ask that question.

Winning a bet would be an example of practical need for an answer to such a
question.

Quite right ! This is not exactly my example. This has more to do with
raising money for charity, but going into detail on that is not really
relevant. Still hopeful on my original question ......
