Ok so I am watching the show on PBS called 400 years of the Telescope. They just showed a rendering of an asteroid hitting the earth. Upon impact into the pacific ocean it showed the earth beginning to incinerate. The other week on Nova they had a similar animation. I also remember several other shows on various "knowledge" networks where they showed the earth getting hit by an asteroid and the resulting earth incineration immediately following.
My rant starts here: Every one of these shows spoke of how off Hollywood's take on this. I just think its odd that if an asteroid were to hit the earth in the center of any large ocean that it would generate enough heat to flash boil the entire ocean and allow the underlying earth to incinerate. I mean if these scientist want to promote the truth then why render an animation where something that is physically impossible and pass it off as the truth?
