    Strange contradiction
1
In one hand :
The particles in the Universe are more than antiparticles
 / Baryon asymmetry /
2.
In the other hand:
 Dark matter in the Universe is more than visual matter

Question :
Does one physic’s hand  know that the other hand do ?

Comment:

It does seem like a paradox, doesn't it?

Actually, these are two unrelated concepts.
Baryons represent detectable matter.
Dark matter represents undetectable matter.
Different stuff.

That still leaves the question about physic's hands, though....

I think that actually, the ‘Baryon asymmetry ‘and ‘Dark matter ‘
both belong to one conception.
Why?
Because antiparticles exist in ‘ Dirac sea ‘, in Vacuum and
 ‘ dark matter ‘, by idea, must exist there too.
They both belong to one and the same reference frame.

Now the questions are:
‘ does dark matter consist of antiparticles or of
 some kind of  different particles ? ’,
‘ do antiparticles make dark matter ?’

To answer to this question we must know that Vacuum is.
But it is a pity, we still don’t have answer to this question.
And Dirac said:
‘  The problem of the exact description of vacuum, in my opinion,
 is the basic problem now before physics. Really, if you can’t correctly
describe the vacuum, how it is possible to expect a correct description
of something more complex? ‘

So ,
all discussions are tautology without understanding that Vacuum is.

Actually, it is very important in physics that the left hand
does NOT know what the right is doing. We do experiments
without knowing the outcomes. When we find conflicting results
 we can use that as a clear indication that we are missing something.
If we 'know' what is expected, it is difficult not to influence the
outcomes so that they compliment each other, that is,
 we cannot trust the results.

But it is a good question, and one worth thinking about.

Some theories of DM assume that DM are their own anti-particles. These
theories also say we should occasionally see a DM particle collide with
another DM particle and annihilate each other, releasing a gamma ray
from an area of space where there should be nothing producing it.
Of course that's just one theory of DM, nobody knows if it's the right
model of DM.
