Black Hole

Today my sweet son came into my bedroom sobbing. He was almost uncontrollable. He told me he was so worried that there would be a black hole near our planet and that the gravitational pull would be so great that it would rip all his arms and legs off and suck it into the black hole. POOR KID!! The things you have to worry about when you are a genius! Most of us worry about money or raising our kids or friends........not if a black hole's gravitational pull is going to rip our appendages off.
