“In science it often happens that scientists say, ‘You know that’s a really good argument; my position is mistaken,’ and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn’t happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.” –Carl Sagan
So, Ben Carson made a speech in 2011 that’s making the rounds, for some pretty scary reasons. I’m particularly concerned with what he has to say about the Big Bang.
In particular, he says that it’s wrong because of a hodgepodge of reasons: thermodynamics, entropy, the orbits of the moons and comets in our Solar System, etc. But the worst part is, I recognize this line of reasoning, and it’s actually common among knowledgeable people who don’t like the conclusions that science draws. And it’s dangerous to all of us.
