This would make black globes next to useless against incoming missiles.
Think of the KE that a missile that has been accelerating for 20 minutes
at 6Gs.  I would assume that 6Gs would have to be a minimum for a missile
and 20 minutes is a combat round!  A standard HE missile has a weight of
0.05 Tonnes which is 50 kgs.  g = 9.8 m/s/s so 6G = 58.8
for a time of 20*60=1200 seconds.

v = v0 + a.t = 0 + 9.8 * 1200 = 70600m/s

            2                                                    11
ke = 0.5 m v  = 0.5 * 50 * 4984360000 = 124609000000 = 1.246 * 10   J

Is that a big number or what!  Splat goes one space ship!

Just think what a small suicide fighter would be capable of (the perfect
place to use a robot pilot --- while attacking black globe shielded
ships).


Worse, since mass is energy (E=mc^2), wouldn't the globe have to absorbe
the energy of a mass placed in contact with it?

I hope I got the above figures correct, I never was much good at physics.
I'm sure somebody on the list will correct me when I'm wrong.
