I recall a theory says that in the earliest time of the universe creation, there are a balance amount of matter and antimatter. Some how the matter outnumber antimatter by small amount, and we have a matter universe here. When the matter and anti matter annihilate each other, what was happened to the energy released? (must be very big)<br /><br />If the universe is a cycle, and then the next and next big contraction and big bang will have lesser energy?<br /><br />What happenned if next big bang, other way around, anti matter slightly out numbered matter? will it be anti matter universe?<br /><br />What happend if the next big bang, anti matter "greatly" out number antimatter? will the universe be more crowded than current universe? since less annihilation will take place? and vice versa.<br /> <div class="Discussion_UserSignature"> </div>

Will there be 999...99 times more stars and galaxies compare to current universe? consider that 0.000...01% remaining of the early annihilation of matter and antimater, currently our universe is consist of 70 sextillion stars (7x10e22).<br /><br />How if there were equal 50%-50% matter and anti matter, will the universe be empty? Since it is empty, how is it going to expand? ecpanding empty space? how is going to be if the universe contract? contracting empty spaces? <div class="Discussion_UserSignature"> </div>

The principle of "matter" and "anti-matter" is relative only to the Universe in which it exists.<br /><br />They're only different expressions of the same thing. If what we know as "anti-matter" was the ruling property, then from our point of view, we would perceive it as "the matter of our Universe".<br /><br />From our point of view, if we lived in an "anti-matter" Universe, we would not be composed of "anti-matter" at all.<br /><br /> <div class="Discussion_UserSignature"> <em>"2012..

And let's add a hypothetical form of matter, something that when added to either matter or antimatter yeilds nothing.

At start off big bang possibly both were equally distributed.Then they got seperated.
