Although this has been suggested before, Shaw has mapped out several swaths where large craters of about the same age are located. Shaw has plotted several other swaths of different ages. The application of chaos theory to solar system debris . Shaw hypothesizes that nonlinear gravitational effects channel asteroids and comets into the inner solar system in intermittent bursts. The bursts are then captured by the earth and other inner planets, with some of these objects grouped in like orbits.
Gravitational feedback occurs from earth to orbiting debris .
In turn, these large objects keep smashing into the same regions and their cumulative effect contols the flow of material inside the earth. Then, this change in mass distribution feeds back to change orbits and impact swaths. It cannot fail to be controversial. William R. Corliss Other Sites of Interest SIS .
