Re: Alpha Centauri Bb: For Real

Now we know that there is a potential to use the sun itself as a gravitational lens--and you don't just get a focal point--but a focal line--so it is good to keep an open mind. Maybe not a mirror--but a lens is doable from our own star 400-800 AU out, which is more do-able than true interstellar travel for now.

Now I want to know how this might apply to beamed energy propulsion--since you have a focal line.
