Over a century ago, doctors invented
a procedure to remove cataracts from
people’s eyes. Among their first
patients were people who had been
blind from birth. The surgery
enabled them to see for the first
time as though they were newborn.
But unlike newborns, they had
acquired language and so were able
to tell the doctors what they were
experiencing.
They didn’t see
“things” that were “out there”; they
saw meaningless moving patches of
color. The patches were not just
confusing in themselves, they caused
confusion with other senses as well.
The newly sighted persons’
understandings of the world were
disrupted. They had to make sense of
it all over again.
The patients had to
learn how to interpret those color
patches in ways that were compatible
with their other sensations. This
entailed developing new concepts of
“things”—groups of sensations
combined into a unitary concept—that
could be interrelated in a concept
of “space.” For the most part, they
had no concept of space.
It also required
“unlearning” many concepts of things
and relationships that had been
developed without visual sensations.
The old concepts couldn’t
accommodate the new visual
sensations.
The task was difficult. Some
patients gave up, closed their eyes,
and returned to their old life in
the home for the blind. The doctors
were surprised to discover that
seeing—the understanding of visual
sensations as “things” in
“space”—was something that had to be
learned. By the time most of us can
talk about it, we’ve taken it for
granted. We take the metaphor
literally: seeing is understanding,
no interpretation or theory seems to
be needed.
In the last few
decades, astronomers have developed
instruments that provide us with
sensations never before experienced.
Telescopes detect “light” from radio
to gamma-ray frequencies. Space
probes provide points of view far
from the surface of the Earth.
The new instruments
have removed the “cataracts” of our
biological sensory limitations, and
we perceive for the first time
patches of new colors. We must learn
again how to see new things in a new
space. Not surprisingly, the experts
in the old way of seeing are having
a hard time learning, and many are
taking refuge in the home of blind
astronomy.
The more we look at
the lights in the sky, the more we
see that they are like the electric
lights on Earth. But understanding
what that means requires work: The
full metaphor must be created.
Nerves must combine sensations in
new ways. The old dog must learn new
tricks.
What will it mean to say “stars are
electric lights”? We must first
unlearn “stars are thermonuclear
furnaces” and “stars are mass and
gas.” We must figure out just how
“stars are loads in a circuit” and
“stars are charges in plasma.”
The space age has
opened new eyes that are giving us
the first sight of an Electric
Universe. We must respond with a new
insight.
