Where is the missing antimatter?

So the Big Bang produced equal amounts of matter and antimatter, but rather than completely self-annihilating, a smidgen of matter was left behind for some reason, maybe having to do with neutrinos, according to NYT.

But if some matter was left behind, why doesn't that mean that an equal amount of antimatter is hiding somewhere? Did some antimatter turn promatter?

Re: Where is the missing antimatter?

One, stop reading the NYT, it is a garbage newspaper written by garbage people. They Need copy; no different from The Sun from the UK.

Two, asymmetry or symmetry and how we got here is just so much speculative fluff. We are here, So let’s Rape this Planet and move on.

I suspect Zeno has hidden it somewhere in the attic.

Re: Where is the missing antimatter?

There can never be a universe comprised mostly of anti-matter. Proof as follows:

1) Either there is something special about matter or there's symmetry

2) If symmetry then there has to be a symmetry break towards matter or anti-matter in any viable matter ridden universe.

3) if 2) then whichever way the symmetry breaks in your universe, the dominant type of matter will be called 'matter' and the missing bit will be the anti-matter.

qed

2) seems a bit weak but it's worth it for 3).

It's not considered missing within the first 24 billion years.

Actually, it does appear that this is legitimately one of many pieces of the puzzle that physicists have not been able to piece together as of yet. Whether OP legitimately expects to find a reasonable explanation on this forum, when leading physicists in the field don't have one, is another issue.

Re: Where is the missing antimatter?

Hint to everyone.

If you flip a coin every time and 1 in 1 bil bil times you take the result and hide it outside the casino what will be the outcome after 10^120 experiments on the rake taken out? Net heads or tails? Goes like root of the experiments. Thats what you call matter now. The winner.

It will be something alright. What if the other side is now hard to detect because after all that was the reason it took 1 bil in 1 bil times to happen.

I have been saying this for years now. Dark matter could be thermal neutrinos with speeds less than the escape velocity of the galaxy. Now what if they are mostly antimatter neutrinos?


Now try to find the right reactions and sequences and test how often a neutrino produced has less than 0.01% the speed of light at which point it decouples from the cross section probability to be reused quickly locally.

https://en.wikipedia.org/wiki/Weak_interaction

What orbits galaxies cannot be moving faster than standard orbital speeds and it has to be mostly spherically distributed because it doesn't interact with any other method than gravity to become flatter and near plane elliptical etc.

What is the only thing that you cannot imagine neutrino doing? Moving slowly and of course it is then that its almost impossible to detect because the reaction rate depends on momentum.

Is the truth hidden at the very end of that tail?

Everything is "just a theory". Some theories are better than others.

Not exactly..

But gravity, evolution, and the Big Bang are all theories that need each other in order to work. Yup thatís right. Science requires faith in theories. Sounds more like a religion.

The message you just typed there reached me all the way over here. That involved scientific theories and didn't require your faith in them.
