Figure 3.9 The mammalian brain seeks to expand its dimension to
fulfill its biological purpose. For example, the huge 2-D surface of
the brain is intricately folded to fill a 3-D volume so that its surface
area will increase. If you laid all your brain cells end to end, they'd
stretch around the world twenty-five times.
call it a. probabilistic foam, or quantum foam. The froth contains holes
to other regions in space and time."
Sally taps on the dashboard. "Could these wormholes be connecting
different areas of our same universe?"
"Yes. In the foam, adjacent regions of space are continually stealing
and giving back energy from one to another. These cause fluctuations in
the curvature of space, creating microscopic wormholes. Who knows,
someday civilizations might be able to use such wormholes to travel the
universe."
The tapping of Sally's fingers becomes more incessant. "But those
wormholes are too tiny for people to use."
"That's the problem, and why we might never be able to use a wormhole.
We'd need a device that spews out something called exotic matter.
