My Venus- thread that leads a disgraceful existence in crackpots corner may be known here. It argues, supported by lots of evidence that Venus'spin has come to a standstill due to a "design flaw", generating an enormous heat in the process. This would have evaporated the oceans and dissocated the water, I tried to visualize how that would have looked at then another flash hit, probably like a gas giant like Uranus, Jupiter etc. A large gas ball with a denser but very hot core. Hmmm The gas giants all seem to be generating more heat than they recieve from the sun. Maybe not so much difference at all. Must investigate, but I have three more projects running. Any ideas?
