Abstract:

In a series of computer runs, a number of lowvelocity particles in three-dimensional space were released in the vicinity of 1 the Earth in its orbit around the Sun, and 2 an Earth isolated in space, and the particles positions were then traced through space. The subsequent steady-state concentration of particles around the Earth for 1 was found to be proportional approximately to the -1 power of the distance from the center of the Earth, while for 2 the -0.68 0.14 power of the distance from the center of the Earth theoretical value -0.50. It is concluded that there is a significant difference in the gravitational concentration of particles around the Earth in orbit around the Sun as compared with an isolated Earth. In the real world, low-velocity particles are gravitationally concentrated by the Earth much more than one would expect from looking at a simple model of an isolated Earth. Author
