How can we be sure that our universe is the only universe? There are theories to multiple universes and parallel universes. Could it be possible that our entire universe exists within a single atom of an entirely larger universe? Maybe thats what exists within each atom of our universe, an entire universe!<br /><br />It's sort of like Men in Black, where a whole universe/galaxy exists withing a marble, and larger creatures, who exist in a larger universe, are simply using us for entertainment. <br /><br />Since we know nothing about what happened before the big bang, it is hard to know for sure if our universe is all that there is. Many physicists say that our universe expands only into itself because the universe is all that there is. I can completely understand this, but this theory has to depend on the fact that our universe really IS all that there is!<br /><br />Are there any studies in present day science, or science a million years from now, that could help prove the fact that our universe is the only universe?<br /><br /> <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.
