West said briskly--exactly as if before a television camera--that Mr.
Dabney had started from the well-known fact that the properties of space
are modified by energy fields. Magnetic and gravitational and
electrostatic fields rotate polarized light or bend light or do this or
that as the case may be. But all previous modifications of the constants
of space had been in essentially spherical fields. All previous fields
had extended in all directions, increasing in intensity as the square of
the distance ...
"Cut," said Cochrane.
West automatically abandoned his professional delivery. He placidly
re-addressed himself to his beer.
"How about it, Jones?" asked Cochrane. "Dabney's got a variation? What
is it?"
"It's a field of force that doesn't spread out. You set up two plates
and establish this field between them," said Jones curtly. "It's
circularly polarized and it doesn't expand. It's like a searchlight beam
or a microwave beam, and it stays the same size like a pipe. In that
field--or pipe--radiation travels faster than it does outside. The
properties of space are changed between the plates. Therefore the speed
of all radiation.
