is a portal through space, and possibly time, created by a black hole linked
opposite white hole somewhere else. A black hole, of course, is a collapsed neutron star that
has teetered past the three solar mass limit into the twilight zone of Einstein's General Theory.
was Albert Einstein with his Special Theory of Relativity in 1905 and his
General Theory of
Relativity in 1916, who set up the parameters of infinity. The former, of course, pegged the
speed of light for all observers at 186,000 mps. The latter showed how the gravitational field of
matter defines the universe through gravitational force. The larger the mass, the larger the gravi-
tational field. The very stuff of space and time can be considered physical entities.
hole is matter that has become so dense that its center approaches infinite
It becomes a singularity. Anything that enters gets scrunched. Any matter, energy, light, etc.
that gets too close will not be able to get out. Once you've crossed the event horizon - you're
there and presumably in trouble.
in the 1960's showed how space and time could be warped around black holes.
of Symmetry would indicate, some theorists speculate, the existence of a black hole's counter-
point a white hole. Matter sucked in by a black hole near Pluto, might simply whoosh out through
a white hole in Andromeda!
are also believed to be built into the structure of space-time at the Planck
(Gh/c^3)^(1/2) =1.6 *10(-35) meters. This length is 20 powers of ten smaller than the nucleus of an
atom so it is far beyond our power to measure. But the nascent quantum theory of gravity seems
to predict that wormholes should be continually created and destroyed at the Planck length. That
means we would be surrounded by trillions of wormholes forming and collapsing trillions - of times
a second. Hawking has recently argued that this phenomena may explain the nature of the
physical constants, like G, h and c. (See Hawking, Physical review D, 1988).
U.S.S Enterprise found a wormhole that was stable only on one end,
which would still be useful
for sending a probe in (and pulling it back before the other end changed) to explore far reaches of the galaxy.
The Bajoran is the only known stable wormhole.
