- Maybe that wasn't totally clear. The asteroid has some guidance
- rockets on it to adjust its trajectory so that it gives
- momentum to the earth and then heads off to say, Jupiter, where it
- slingshots off in just the right way to pick up some momentum
- and head back to earth. And so on and so on. The orbits might
- require a retrograde pass around the sun or some other such fancy
- shooting, but I think no laws of physics are violated.
-
- Hmm. A second thought. Maybe the Magratherians (see Adams'
- Hitchhikers Guide to the Galaxy) are already using comets to
- adjust the orbits in the solar system :-) Comets are sent in
- from deep space, steal momentum from Jupiter and redistribute it
- to the other planets! This would eliminate the need for the
- Oort cloud to explain the precision with which new incoming comet
- orbits approximate parabolas !-) This should make Tom vanFlandern
- very happy!
