No, this makes *not* sense, since we already know that about 90%
of dark matter is not baryonic!



can this gravitation FX be produce by something other that matr?

As I already pointed out: by energy. Photons cause gravity. Dark Energy causes gravity.


The electromagnetic force still has the same power then. It doesn't
matter that everything gets colder.


yes, of curse but the weakforce will be gone! 

Why on earth do you think so?



Because the weakforce can't survive in empty cold enviroments. 

Why on earth do you think so???


the constant friction of matenergy is what keeps the weakforce
going.


Why on earth do you think so??? The weak force has precisely nil to
do with friction!



and what communication particle will be the most effective producing
a gravitational effect?


Depends on what you mean with "communication particle".



particles moving at c

Why do you call that "communication particle"?


electrons can also be communication particles

You just said that communication particles are particles which move at c. Electrons don't do that.


but they are easely trap by nuclei. 

So what? Interstellar space is quite empty. Not much there to trap them.


any particle that's moving
in spacetime at great speed it's a communication particle.
they carry information from one place to another.


Yes. So what? I still think it's strange to call them "communication
particles" because of that.

yes but i imagine neutrino density alot stronger than
photonic energy when all the stars are dead.


Why do you imagine that? Have you ever done a calculation on that,
or simply looked at the numbers? You *do* know that numbers for the
photon and the neutrino density are available in cosmology books,
don't you?


i know the numbers now and for times behind and ahead 

I doubt that. Give the numbers, please.


but we are talking about the future of spacetime when
stars are no longer visible in the sky anymore!
can you imagine neutrino density by then?


Imagine, no. Calculate, yes.
