Another violent episode in the history of the solar system is currently being projected – this time involving Venus (shades of Velikovsky). At http://www.smithsonianmag.com/science-nature/giant-planetary-smashup-may… … we are told this may account for the hot temperatures of Venus and its thick atmosphere. Does this mean scientists are now thinking in terms of co2 being inadequate to account for the warmth of Venus?
The spokesperson does of course tell us this could not have happened relatively recently but must have occurred billions of years ago.
