No Big Bang? Endless Universe Made Possible by New Model

[SpeedFreek]

Hi brellis!<br /><br />I agree it seems like a cop-out, but then maybe occams razor has been at work! It does seem a little too simple, but I will reserve judgement until it has been thoroughly peer-reviewed at least!<br /><br />It does have a certain elegance about it though. <div class="Discussion_UserSignature"> <p><font color="#ff0000">_______________________________________________<br /></font><font size="2"><em>SpeedFreek</em></font> </p> </div>

Well....technically we don't know if dark energy exists. But we know some thing is causing the expansion. Perhaps it is the nature of our universe... we can never really know.<br />It seems as if all these theories have their flaws.<br /><br /><font color="yellow">Pick me up a copy when it comes out in the next billion years <img src="/images/icons/smile.gif" /></font> <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>

I think it is a very hard thing to understand. If it is the actual dimensions of the universe expanding, what is causing this expansion? Dark energy might be a name for the expansion, but is it really energy in any way? Is it something to physics that we have not even discovered yet? <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.

I've just re-read the whole article (not just the part I posted) and it may not be as simple as the matter get divided up between the new universes.<br /><br /><font color="yellow"> At the turnaround, each fragmented patch collapses and contracts individually instead of pulling back together in a reversal of the Big Bang. The patches become an infinite number of independent universes that contract and then bounce outward again, reinflating in a manner similar to the Big Bang. One patch becomes our universe.<br /><br />Frampton and Baum circumvent the Big Bang by postulating that, at the turnaround, any remaining entropy is in patches too remote for interaction. Having each "causal patch" become a separate universe allows each universe to contract essentially empty of matter and entropy. "The presence of any matter creates insuperable difficulties with contraction," Frampton said. "The idea of coming back empty is the most important ingredient of this new cyclic model." </font><br /><br />To me, this looks like all matter distintegrates before the fragmentation, then each universe collapses, contracts, rebounds and comes back empty except one. The one with all the energy in it? <div class="Discussion_UserSignature"> <p><font color="#ff0000">_______________________________________________<br /></font><font size="2"><em>SpeedFreek</em></font> </p> </div>

at least this stuff makes for good sci-fi scenarios.
