Expanding Universe condensing?

[majornature]

Ok, after the big bang explosion of condensed matter and anti-matter, the universe accelerated let's say for 15B years. <br /><br />So could there be an explanation that the expansion and cooling of our universe be that it is condensing back into a massive atom?<br /><br />Just wondering.... <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>

It may not be condensing yet, but it may start in years to come.<br /><br />It's a theory called the "big crunch". Scientists are still observing a red shift in distant galaxies, which means that the universe is still expanding. If scientists observe a "violet shift" in distant galaxies, then it means the universe is condensing.<br /><br />You asked if there was an explanation that the expansion and cooling of our universe be that it is condensing again. Are you asking if the universe is expanding, so it should be condensing? I'm confused.<br /><br />P.S. What is anti-matter?

Big crunch is inevitable opposite of big bang.

"What is anti-matter?"<br /><br />Anti-matter opposes matter its another way of saying dark matter.This should help you.

As I understand it, there isn't enough matter / density in the universe for the big crunch. Expand, cool off, and go dark for all of eternity.<br /><br />

At the time it was assumed the it was "dark matter" causing this expansion. <br />I was asking if there could possibly be a factor in the years to come that the universe will soon become totally dark and frozen?<br /><br /><font color="white"><b> True knowledge exist in knowing that you know</b></font>font color=black><b>NOTHING!!!!!</b>/safety_wrapper> <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>

Dark matter is the "missing mass" we can infere by its gravitational effects on our visible baryonic matter, but it does not interact with electromagnetism, otherwise it would be visible. <br /><br />Anti-matter is otherwise "normal" positive matter that make up our bodies, except it is negatively charged, interacting with electromagnetism. This is anti-hydrogen, anti-electrons (positrons), etc. Matter and anti matter colide and anhiliate into photons, electromagnetic energy.

Anti-matter is supposed to be matter with an opposite charge in such a way that protons are in the "cloud" where the electrons are supposed to be, and electrons are in the nucleus where the protons are supposed to be, IIRC. <br /><br />Is this also the definition of dark matter? <br /><br />Edit: never mind. it apparently was answered already..
