There is an old joke "you can put a billion dollars worth of plutonium into a suit case, but only briefly.."

So if you travel 3 years you get sqrt(3*3+1)-1= 2.16 light years, about half way to Alpha Centauri, so decelerate is the same, so approx 6 years out, 6 years back, 12 years, from the travelers perspective? oh I see you updated it, that would be earth dwellers time. Thanks! Another little point...

I thought about it in these terms: If you converted the entire mass of the earth into energy, (by E=mc2) that vast amount of energy would still only exert 1G of gravity.

Just a simple little question as my first post here.. Suppose you have a space craft that has an engine that can exert an acceleration of 1G. You fly this to Alpha Centauri accelerating, then halfway turn around and decelerate at 1G, so you have gravity for the whole trip. Once you arrive, you...
