<font color="yellow"> If there are billions of other galaxies, and new planets forming every day, there should be other life forms out there </font><br /><br />I agree with you on this. Life has to be somewhere out there. The way I see it, our own existence on this planet is proof that life is a very real thing that can take shape within the universe. So, what's to stop it from happening everywhere?<br /><br /><font color="yellow"> What's beyond our Universe? Are there Billions of Universes out side our own? If our Cosmos was composed of many Universes would there be multiple Cosmoses? </font><br /><br />The big bang model suggests that there is nothing beyond the universe, there is no "beyond" in the first place. The universe expands only into itself, because the universe is all that there is. <br /><br />As for other universes, who really knows, no one knows. It IS possible that there are billions or infinite other universes, but we may never know that they're there. The Cosmos represent everything within this universe, because that's all we know. We have no way of knowing anything beyond our observable universe, it is the limit to our knowledge. <br /><br />The term 'observable universe' means what we can actually see. The 'material universe' is how the universe should actually exist. The boundry between these two is due to the limit of the speed of light. Light must reach us from the Cosmos to send the information that we can observe. <br /><br />Picture this: If you were standing in a room with no doors and no windows, would you be able to come up with scientific evidence that explains what exists beyond the walls? Of course not! It is impossible. <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.
