Superconductivity is capable of increasing radiation pressure a million times stronger than normal, according to a new discovery.
Radiation pressure is the normally gentle push of electromagnetic radiation on matter, similar to the slight press light makes on a mirror. This effect is negligible in our everyday experience, on the macroscopic scale at which we live. However, this force can become significant in space, when produced by objects as powerful as stars.
The radiation pressure falling on a typical chair from a 100-watt incandescent light bulb is roughly one-trillionth as strong as atmospheric pressure at sea level. This same effect in space also drives tails of comets to always point away from the sun. This pressure can also be utilized in solar sails to propel mechanical craft through space like ships on the water. Massive laser pulses can be controlled using the radiation pressure from an oscillator within a common wristwatch.
