Questions about the Universe

[majornature]

First question:<br />I know that are at least 26 dimensiions in this universe.<br />Eleven of we study in the laws of physics. Considering that the universe is flat and four known dimensions, could the a crunch in the universe occur if other six dimensions was to wrap it's self around our four dimensions?<br /><br />I know it probaaly sounds crazy but i'm curious!!!<br /><br />Second question:<br />I read that when the universe was an infant, it was the size of an "atom". If we were to journey into the fifth dimension, would we still see our universe, which has been accelerating for billions of light years, as an atom? <div class="Discussion_UserSignature"> <font size="2" color="#14ea50"><strong><font size="1">We are born.  We live.  We experiment.  We rot.  We die.  and the whole process starts all over again!  Imagine That!</font><br /><br /><br /><img id="6e5c6b4c-0657-47dd-9476-1fbb47938264" style="width:176px;height:247px" src="http://sitelife.space.com/ver1.0/Content/images/store/14/4/6e5c6b4c-0657-47dd-9476-1fbb47938264.Large.jpg" alt="blog post photo" width="276" height="440" /><br /></strong></font> </div>

There may be many fewer than 26 dimentions and we know very little except about the 4. 'Wrap it's self around" might be possible. What would a crunch be like? Neil
