Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>However, if we can identify the unknown particles that we suspect must have existed at the instant of the singularity and the subsequent event of 'expansion', and 10 to the negative billion seconds of the initial "Big Bang", then I guess we're well on our way to at least discovering a small fraction of the meaning of physical existence.<br />Posted by ZenGalacticore</DIV><br /><br />Who suspects that there were particles at the moment of the big bang, I have always heard there was only energy? The basic forces had not even sepatrated until 10^-6 seconds or so. Quarks formed at about 1 second. <div class="Discussion_UserSignature"> </div>
