Stephen Hawking and the late Richard Feynman are two notable examples.<br /><br />Roger Penrose sees it differently. While conceding that quantum physics does indeed drive you to the many worlds concept, he believes that when gravity is successfully brought into quantum theory, a whole new picture will emerge which will show that things at our level behave differently from things at the quantum level. <br /><br />I find Prof Penrose's version more acceptable, logically. <br /><br />But now a "team of scientists has succeeded in putting an object large enough to be visible to the naked eye into a mixed quantum state of moving and not moving, until someone looks at it, and it settles for one or other state.<br /><br />http://www.nature.com/news/2010/100317/full/news.2010.130.html <br /><br />How about that?Anonymousnoreply@blogger.com
