During the first few microseconds of the Big Bang, various entities of matter and antimatter fought a war: the antimatter folks lost.
I heard the matter folks cheated.
I was listening a physics book some time ago. IIRC, the Universe exists because a there was a slight imbalance between matter and anti-matter when the Big Bang happened.
Any physicist who can’t see the Hand of God there is in a sad state...
That is precisely the answer. I'm surprised the writers of the article don't seem to get that. Read Alan Guth. Back in the 80s he and others postulated a slight asymmetry in the huge amount of stuff of the big bang: 50.00001% of it matter, 49.99999% of it antimatter. 99.99999% of all stuff annihilated and the remaining .00001% (which is all the galaxies in the known universe today) is the leftover matter from the slight imbalance.
If there were equal amounts of antimatter and matter today (as the article seems to yearn for), then there very soon there would be nothing.
Matter + antimatter -> annihilation -> nothing.
I guess they are saying we should be able to see whole galaxies of antimatter? Would we be able to see them and know that they are antimatter?
