Now for Jim's end run, suppose that we do build a small antimatter rocket 
of some sort. Let us make the sail out of vacuum deposited Tungsten which 
is also refractory and is still quite strong. It is almost as massive as 
Uranium, which might give us a great deal more thrust when we start to 
feed it to the antimatter rocket to decelerate.

As wondering men have always done
Since beauty and the stars were one,
Though none so hard as I.
