In this simulation, an "electromagnetic suspension
bridge" is created by attaching a lattice of positive
and negatively charged particles between four fixed
corners, and adding a downward gravitational force.
The tension in the "bridge" is supplied simply
by the Coulomb interaction of its constituent parts
with the Pauli force keeping them from collapsing in
on each other. Initially, the bridge only sags slightly
under the weight of gravity, but what would happen to
it under a rain of massive neutral particles? Press
