Camelot, 9:30 AM Wednesday morning, time for javelin practice.  Percival
and Galahad stand fifty yards apart, Percival holds a shield in front of
his chest, and Galahad chucks a spear at him.  Galahad's aim is perfect;
Percival holds the shield in front of his body until the javelin is in
the air, and then moves the shield off to one side, smug in the knowledge
that he no longer needs it.  By all rights he should get killed, but
nothing happens;  the javelin disappears as if snatched up by an
invisible hand, and Percival stands there with a big ____-eating grin
on his face.

Galahad is dumbfounded;  Percival explains it to him:  "You don't know
your own strength, son;  you done chucked that spear so fast, that the
component parts of the spear arrived INSTANTANEOUSLY at the shield as
you were in the act of throwing it.  After that, i.e. after you thought
the spear was in the air, there was nothing more of it left for the
sheild to absorb, and it (the shield) was no longer necessary.

Once Galahad got over that, i.e. after he'd had a couple of drinks,
Percival tried to explain Ralph Sansbury's experiment to him.

The spear represented the little ten-foot or thereabouts spears of lasar
light which we presume would be chopped off by the nanosecond gate (we
percieve light to move about a foot in a nanosecond) in front of the lasar;
the second nanosecond gate, or Pockel cell in front of the target
represented the shield.  Given any of our normal assumptions about what
light is, something should have registered on the photo-sensors behind the
shield gate, but nothing did.  Light did not "travel" to the gate as
we would assume.  The component parts of the light arrived instantaneously
and were absorbed as the lasar spear was being formed up.  Afterwards,
there was nothing there.

Einstein and others assumed that gravity was a different kind of thing
from electromagnetic or electrostatic forces because of the instantaneous
propagation of gravity.  The Sansbury experiment changes that;  the door is
now open to comprehend that a change in planetary electrostatics could
indeed cause a change in planetary gravity.

Einstein attempted to account for the non-additivity of the velocity of
light by his use of relativistic time.  But having the component parts of
light be instantaneous would also account for the observed non-additivity;
relativistic time is unnecessary.  Moreover, Sansbury describes a number
of phenomena, worm holes, cosmic strings etc., as being nothing more than
necessary artifacts of an inadequate model, i.e. they do not really exist
in nature and an adequate theory would not require them.
