sticky bead argument

Meanings

name
  1. A thought experiment linking general relativity and gravitational waves, based on the idea of two beads sliding freely (but with a small amount of friction) on a rigid rod. As the wave passes over the rod, atomic forces hold the length of the rod fixed, but the proper distance between the two beads oscillates. Thus, the beads rub against the rod, dissipating heat.
