-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

QUOTE My initial thought was "but that requires dumping a massive load of energy". However, a quick look at Excel, and I see (assuming an early Venus rotated at terrestrial kind-of-rates) some 1.9*10^29 joules of rotational energy needs to have been absorbed. Just a thought... perhaps this atmospheric despinning added to Venus' hot surface temperature. The despinning could have created very high surface temperatures for the first couple of billion years and the greenhouse effect would add to the temperature and keep it from cooling as fast. Or vice versa. Very odd planet, but then, aren't they all... --Bill -------------------- |
