Re: Laser snipers

I had a physicist friend that made a SF RPG.  Initially he was going
to use a laser drive, that is until he figured out that at 1G
acceleration you could kill a planet with the thing.

I thought that was the idea; chem and/or nuclear drive for significant
fractions of 1G, light drive for 0.00000000000... G, for STL
interstellar.
Very low thrust, but next to no reaction mass, and very efficient over
the
very long haul.
