If the sound depended on the object's age, then I would say that younger objects put out a higher frequency. I know nothing of this topic, but I wouldn't think that age has anything to do with the vibrations that it puts out.<br /><br />I would predict that it matters more on the object's energy output. Blackholes release exorbitant amounts of energy, so it would almost make more sense that they would release higher frequences. <br /><br />Again, I know nothing of this topic, just guessing <img src="/images/icons/tongue.gif" /> <div class="Discussion_UserSignature"> <p> </p><p><strong><font color="#ff0000">Techies: We do it in the dark. </font></strong></p><p><font color="#0000ff"><strong>"Put your hand on a stove for a minute and it seems like an hour.
