If you haven't read this, it's absolutely worth the read if you like hard SF and space opera. I loved it. Take the sale :)

And even with much slower travel, say 25% of c, which we can see ways to do today, Alpha/Proxima Centauri is only 17 years away (probably closer to 25 when you add speeding up and slowing down), which isn't easy, but isn't impossible.

No more waiting for Godot. I got tired of waiting for Buck Godot Buck Godot _The Gallimaufry_ in print; reading on a screen is too much like work. After legally purchasing the PDF copy, this is just back from the binders. Rest easy, Phil Foglio I still wait eagerly the
