"QUANTUM FOAM"
Many physicists believe that space is composed of an ever-changing
arrangement of bubbles or loops called quantum foam.
We show that
vibrations produced by the foam are almost within range
of detection
with modern gravitational-wave interferometers.
Our quantum foam
scenario is consistent with Hawking's estimate of black
hole lifetime
and the theoretical bound on the amount of information
that can be
stored in a spatial region. We also show that clock
precision and
bounds on computation are related to black hole and quantum
foam
physics. This simple picture links together some
of our concepts of
information, gravity, and quantum uncertainty.
