I recently vacationed in Northern California at the home of a Stanford physisist who has done research on Orbs. Orbs can be detected in digital photos, and to a much lesser degree with film, and seem to be attracted to moments of innocence and goodness(love). I highly recommend a video and book that he has out on the topic. This is mind blowing stuff. There is so much going on around us that we are not aware of, and cannot see. The guys name is Klaus Heineman. And I have found the book and accompanying video cheaper on amazon and borders. Here's the site.Tim.
