Re Dyer, it seems to me you are arguing about infinity*zero. I don't think I should accept that...
I'm arguing that if v(t) is your speed as a function of t (where t is the time in the reference frame of the galaxy), then the integral from 0 to infinity of: (1 - v^2/c^2)^1/2 dt can be made to converge. This will work if you set v(t) = (1 - exp(-t))c, for example. http://en.wikipedia.org/wiki/Proper_time Sincerely, Adam P. Goucher
still don't know whether I should buy it. That sounded good for a minute, but another way to put it is you integrate proper time along the curve of brownian motion... which is an integral I doubt can be regarded as even existing. Anyhow, another issue with all these "solutions" is, your mass will become huge when you & buddy go that fast, exceeding by far the mass of the rest of the galaxy, causing collapse of stuff into a giant black hole. I think you will be able to outpace the collapse and meet buddy before you both die in the singularity, though, because larger mass holes give you more time to live. :) On 2/2/14, Adam P.

Indeed for a particle following a Brownian path, I'm not even sure that "velocity" has any meaning, hence the special relativity time-dilation formulas based on velocity, may not have either. But we are arguing about large numbers of angels on pinheads. -- Warren D. Smith http://RangeVoting.org <-- add your endorsement (by clicking "endorse" as 1st step)
