Gravity and Black Globes

	Here is some stuff which a friend of mine has ask me to repost.

     1)  Can a ship in a black globe be detected by a densitometer?
     2)  Can a ship in a black globe be affected by a repulsor or
 tractor?
      Its not necessary to get the right answer, just one that seems
 consistent with Traveller.  As the answers build up and the discussion
 progresses, there might be a problem with consistency, in which case
 we can go back and change an answer.
      To let you know what I'm really doing, I'm planning to write an
 article tentatively called "Tech Briefs: Gravitics".  This is an
 intensely complex subject considering the many different ways
 gravitics are employed in Traveller, from stiffeners to TDX.ALI'm not
 so concerned about explaining gravitics as I am about describing
 reasonably and consistently how it is applied in Traveller.  So, I'm
 hoping this open discussion with the rest of you will help.
      I'm starting off the black globe because Mike Jackson (Third
 Imperium fanzine; Canada) was thinking of doing an article for Digest
 on globes.  So, this will help his work as well.

     Mass is related to momemtum (the faster you go the heavier you get).
     If a ship has momemtum it has mass (as far as I know, at least according
to Einstein's theories).  However, I don't know if it has the mass that could
be detected by a densitometer (I don't believe densitometers measure mass as
such).  Maybe WILSON can pass this onto USENET (there might be more technical
people there, ie. some people who know more physics than we do, to give us a
better answer).  If the globe has mass, it might probably be affected by a
tractor or repulsor.
