#3054 How far does artifical gravity work?

How far does the artificial gravity generated by a grav plate work?
I mean, if it extends as far as normal gravity, you've got a potential
terrorist weapon against an entire planet:  Give up or we'll turn on
a large anti-gravity field and blow your entire atmosphere into space.

#3055 Re: How far does artifical gravity work?

This was an interesting problem I had to deal with in the game I was writing.
I assume that in Traveller, antigrav is inverse-squared, like regular
gravity. This is OK, because you can't build an efficient grav system
for more than one gee for any significant mass. For my game, where wormholes
were used for star travel, you could swallow a star system with such a
device.

  I agree that that is the logical answer, but I remember either the Starship
OpMan or Grand Survey claiming that artificial grav inside a ship falls off
*faster* than normal gravitation.

  Ignoring the possibility that this is the result of some 'blackbox doubletalk'
the best explanation (IMHO) is that starship hulls are grav-shielded similarly
to densitometers to keep the artificial grav inside them to prevent it from
messing up the environment.
