Re: starship-design: Travel close to the speed of light as you fly a Star Ship to a distant Star

Hi Group,
Let's see if I can say something sensible.

We all know that a hydro-fusion ramjet just ain't gonna get to 0.9 c let alone .999etc.
Also I don't know how Larry calculated his figures but they're way off. To reach a gamma
of 343 it'd take 332.5 years real time, and 12.66 years tau. He got the rock against the
windshield right though.

I'm a bit suspicious. Sounds too eager to have people visit his site and download. Does
he have a virus he wants to share?
