Poynting-Robertson effect would remove space dust in an old solar system (Talk.Origins)
- The Poynting-Robertson effect causes orbiting particles (on the order of a centimeter in diameter) to slow and fall inward because solar radiation falls slightly more on their leading edge, like raindrops on a speeding car. If the solar system were old, the Poynting-Robertson effect would have caused all particles above a certain size to spiral into the sun, removing them from the solar system, but we still find interplanetary dust.

It is agreed that this is based on an error. However, comets show that radiation pressure can push particles away from the sun at a fairly good rate, so these particles are being pushed out of the solar system and not toward the sun. So the only real question is, do comets and asteroids resupply this dust quickly enough to account for what is known to exist.
