Analysis shows that a parachute configuration would collapse from the forces exerted by shroud lines, since radiation pressure does not behave like aerodynamic pressure, and would not act to keep the parachute open.
At these very high vacuums the effect of photon radiation pressure on the vanes can be observed in very sensitive apparatus (see Nichols radiometer ) but this is insufficient to cause rotation.
Because the ratio of surface area to volume (and thus mass) increases with decreasing particle size, dusty ( micrometre -size) particles are susceptible to radiation pressure even in the outer solar system.
As the formation process continues, radiation pressure continues to play a role in affecting the distribution of matter.
As the radiation pressure scales as the fourth power of the temperature, it becomes important at these high temperatures.
Cosmic effects of radiation pressure Radiation pressure has had a major effect on the development of the cosmos, from the birth of the universe to ongoing formation of stars and shaping of clouds of dust and gasses on a wide range of scales.
