I am a highly qualified astronomer and I believe and say that an asteroid is headed to collide with the earth. There are also many respected astronomers that disagree but using the same critical thinking path you arrive at the same conclusion as the video “professor”. Others join in with their own potential disasters.

So now we always have to act to prevent the worst case scenario for long range theoretical scenarios backed by assumptions using computer models?…. But! Wait! The models worked for subprime mortgages didn’t they?

Give me a break. This is just BS (not Batchelor of Science) and definately not real logic.
