shepherdless: 1. Minor point, but I think you have some of the physics slightly muddled there.
On the 0 zero sum energy universe: I should not have been referring to the matter/ gravity balance but the matter /antimatter near balance during the big bang. my idea is, that it took tremendous energy to have a universe come into being and then send it on it's way expanding. If that energy was and always exists in the "nothing, void" well, why would a creator not be able to use it?
you have read some fundamentalist Christian literature that suggests that life or evolution contravene the second law of thermodynamics. I do not remember, but like to hear your counter arguments. Whenever I see a law- defying act, and life is that in a sense, I am in awe. that is why I prefer surfing to skiing. Surfing you do on energy, skiing on gravity, a compelling downward force. So, life, like flying aerobatics, surfing is a divine experience. the beginning of the universe is kind of divine too.
I am a worker innovator, and it is hard to convince us of the non-existence of at least a non-material beginner at the material's beginning, the Deist option.
PS: I like your 4 times that flight evolved. sounds like the 4 natural laws that allow airfoils to lift. it is inevitable in both cases. !) Newton's pushing air down, 2) Bernoulli's suction upward, 3) riding the circular the wave that the airfoil generates, and 4) centrifugal force that exerts an upward, outward pressure from the curved airflow.
