Why is our universe assymetrical?

<p>Greetings this is my first post</p><p>&nbsp;</p><p>Why is the universe assymetrical instead of what it should be according to physics?. The big bang produced equal quantities of matter and antimatter that should have collided and converted the lot into pure radiant energy in the form of Gamma rays</p><p>This did not happen , luckily for us but has an explaination for this ever been found?</p><p>Alan</p>

Hopefully, when the LHC comes back online in the spring, we will get some more information to digest.</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Quasars are super hot emitters that radiate energy of a continuum over a wide spectral range. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
