Blushing Asteroid

Proponents of the electric universe believe that standard age estimates of asteroids are spurious because they depend on unchanging planetary orbits.

NASA caption: This enhanced false-color image of Ida with its small satellite, Dactyl (right), is a vivid example of the effect of space weathering on asteroids. Blue regions on the asteroid tend to be associated with fresh, young craters where subsurface material recently has been exposed to space. Red regions on the surface correspond to old craters and flat surfaces that have not been disturbed in a very long time.

The electric universe interpretation considers standard age estimates of asteroids spurious because they depend on unchanging planetary orbits and the belief that gravity is the only force ever operating in the solar system.

Many asteroid families are red because they were torn from Mars during planetary electrical close encounters. The craters were not formed by impacts but were "machined" by electric discharges between the asteroid and Mars as they separated. Hypothetical low-velocity mechanical impacts in the asteroid belt will not produce neat circular craters. The craters with bluish bottoms were probably the last formed by electric arcs. Earlier craters (by hours or minutes) were covered by later excavated material. Our prehistoric ancestors were witness to the events so the asteroids have been in space for thousands of years, not millions.
