When galaxies collide, they don't touch, they just fly through each other, there's too much space between stars for anything to collide.
Baryon asymmetry
the gas between stars do collide tho

Oh cool, thanks for the lead. I have a friend who tells me about this stuff, by don't work on it myself.
What it there reference for this quote?
> massive set of gamma ray bursts
there is no proof of magnitude of such bursts. Even CMB could be this "glow"
quantum fluctuations
That zone could technically be beyond the event horizon of the observable universe.
>Of course what happened to all that strange matter and why none of it has been directly observed yet are open questions.
it's dark matter
boom nobel prize please
>what could have caused this asymmetrical
probably when you rigorously compute all the amplitudes there is a strong effect matter dominates because zero and infinity are both non-negative numbers
but even anti-matter isn't negetive, it's just opposite in charge and spin direction from normal matter
