ok so I should have finished reading the thread before i replied, but, to
measure how far a gravitational feild propagates, wouldnt you have to create
a new field and measure how fast it propagated? wouldnt all the existing
fields have already have extended as far as they are going to reach? or do
they actually propagate forever in a continually reducing strength? even if
it does, how do you measure how fast something is travelling that is already
so far away from you and you cant travel that quick? sortof like a cop car
with a speed governer trying to catch a lamborghini isnt it?
