I’ve been reading some posts at Malagabay including the Drake Passage one and find it amusing that devotees of the bolide impact sect seem to invariably ignore the basic physics of impact collisions. That if the Earth was clobbered by a large meteorite impact then it will not only behave elastically to the collision but would also move into a new orbit.
Or its mass of inertia is so large that it remains locked in its orbit?
Given that the mainstream paradigm assumes the Earth has been in its present orbit since “the beginning”, any impact seems to have its energy converted totally into heat and partial melting rather than, billiard-ball-like, bouncing into new positions.
The Earth is supposedly hanging in “space” through which it can move freely in response to any impact from another celestial object.
But to assume the Earth is orbitally immoveable suggests too many have had too many cranial impacts from 4×4’s.
