A lot of you are writing in about the "Big Bang machine," saying you're concerned about the black hole possibility.  I understand why some of you are worried:  The YouTube animation seen on Tuesday's show would make anyone nervous.  But honestly, I don't think we have anything to worry about.  If there were a serious threat that a massive black hole could form, I'd like to believe that this entire project would be illegal.  After all, no science experiment I've ever heard of is worth certain death.

Consider this, too:  A large black hole in space is believed to form when a massive star collapses.  The Big Bang machine is beaming particles - little "blips" that are nowhere near the size of the earth - let alone a star.  So I think that, if a black hole is formed, it'll probably be a very tiny, unstable one, as the scientists say.

Whether you're for or against the experiment, I don't think we should lose any sleep over it.
