This news story reminds me that just because something appears millions of times on google doesn't make it true: http://news.yahoo.com/einsteins-laws-prove-ghosts-exist-144407090.html A quotes from the story: "A recent Google search turned up nearly 8 million results suggesting a link between ghosts and Einstein's work covering the conservation of energy." Apparently, ghost hunters claim that since the human body has electrical activity when alive, that electrical energy must stay around when the human dies. (Not sure how/when they think the energy is created in the body...)
