" Hull devised and built in 1901 a radiometer for this purpose [to test the pressure of light] which left no doubt as to its reality or magnitude. Subsequent theoretical investigations by Schwarzschild showed that for particles of dust a few millionths... "

...years, but in this case, was required to detect and measure it. The well-known American physicists Nichols and Hull devised and built in 1901 a radiometer...repulsion is less, but the giant white stars of Class В repel such minute dust particles fully ten times as powerfully as the sun. Larger dust particles,...

...from more accurate data confirm Schwarzchild's conclusion that for a particle of the optimum size and the density of water, the repulsive force of the sun's radiation is about ten times the gravitational attraction, and show that for stars of the same brightness, but other spectral types,...
