Why is our universe assymmetrical

[Alan McDougall]

Why is our universe asymmetrical instead of symmetrical. After all the same quantities of matter and antimatter were created in the moment of the big?

 

Luckily for us the antimatter "went elsewhere" and we live in a universe dominated by matter

 

The matter/antimatter scenario of the early universe should have annihilated each other leaving the universe a soup of game rays, no stars galaxies,etc

I think the bigger question is "why is the universe non-uniform"

 

If I had to guess, it would be because I believe our universe is the result of cosmological natural selection

The matter/antimatter asymmetry is one of the big open questions of cosmology.

While it is not known as to why there is vastly more matter than antimatter in this universe, some believe that the CP violations in symmetry in the decay of particles might provide a clue.

Yes, but it's still unanswered because known processes don't account for the magnitude of the effect.

May be because there is no perfect balance of physical forces throughout the universe. In the beginning, believed that matter and antimatter (atomic particles of opposite electric charge and spin) that exist in almost equal amounts. Keyword is "almost" because, if the size was really equal, as we know matter has not been able to form and stay in form, rather than particles destroy each others leaving nothing but the gamma rays. Was enough material (perhaps only 1% of the original) to allow the physical universe in the form.

 

There are other enemy forces are not equal, including the expansion of the universe against the total weight. It turns out that gravity is insufficient to have an effect there.

 

It could be that the imperfection of the universe is what allows it to be

[Daecon]

Maybe the Universe is like a giant magnet-type thing, where Matter is concentrated at or directed to one end and Antimatter is concentrated at or directed to the other end.
