Dwelling on that 1 g thing...

[edit]

... you know, I recently read somewhere that in order to use classic rocket fuel to travel to Alpha Centauri and back at 1 g, we'd need more than our entire Sun's supply of hydrogen, just to carry a few people— and all the fuel needed on the way. And where will we find the oxygen? Let's just forget it - DVdm (talk) 22:11, 9 June 2016 (UTC)[reply]

Indeed, classic rocket fuel is not going to work. Something new is needed. Fusion? But there is plenty to see and do still here in our solar system! Rjljr2 (talk) 22:18, 9 June 2016 (UTC)[reply]

Even next door already! - DVdm (talk) 22:26, 9 June 2016 (UTC)[reply]
