Conspiracy Theory # 18-11
A couple of years ago, some astronomers calculated that a giant asteroid was going to hit the earth in 2028. Then later, NASA came out and said there was an error in the calculation, and that it was going to miss us by a million miles or so. But I think it *is* going to hit, and the government is doing secret experiments and plans to divert it. They don't want us to know because they don't want us to panic.
Maybe I should build a bomb shelter.
