      Cosmology: two ideas

    The  ''big bang'' idea explains how hot singularity
    created billions hot stars when the rest of the universe
    is extremely cold
    Big bang says nothing about where did ordinary matter
    come from (it says: chickens come from eggs and eggs
    come  from chickens:  singularity <---------> big bang )

    This idea contradict ''dark matter - antimatter'' idea
    #
    To save gravity as universal  law for galaxies the dark matter
    was invented
    Dark matter is extremely cold stuff
    Dark matter is passive / neutral stuff (doesn't have electric charge)
    This cold stuff is much more in universe than normal matter
    Dark matter is seed of normal matter and of formation of stars.
    #
    To create gravity (stars) needs not only matter but also energy.
    Quantum antiparticles ( antimatter) are cold stuff that carry itself
    enormous pure energy (according to Dirac: -E=Mc^2)
    Each antiparticle 10^36 times stronger than dark matter particle
    (graviton) and therefore each antiparticle can manipulate with
    huge stuff of dark matter
    Antiparticles (through so called ''quantum fluctuations'' ) involve
    dark matter in process which was ended by creation of all visual
    stars, galaxies  . . . etc

    But it does: baryonic matter can form because the temperature of an
    *expanding* universe grows *smaller*.

    (it says: chickens come from eggs and eggs
    come  from chickens:  singularity <---------> big bang )

    No, it does not. The Big Bang theory does not require an initial singularity.

    No, it does not contradict dark matter or antimatter.

    And dark matter is not the same as antimatter.

    To save gravity as universal  law for galaxies the dark matter
    was invented

    Not only because of that.

    Dark matter is extremely cold stuff

    There is strong indication that the dark matter in the current standard
    model of cosmology is cold. Therefore the model is called ΛCDM model, where “Λ” stands for the cosmological constant used in the model (now equated with
    dark energy) and “CDM” stands for cold dark matter.

    Dark matter is passive / neutral stuff (doesn't have electric charge)

    No, the quality of electric charge cannot be ascribed to dark matter in the first place because apparently it does not interact electromagnetically and
    we still do not know what it is (only what it does and does not do).

    This cold stuff is much more in universe than normal matter

    Correct, according to the standard model whose correctness you previously denied. That is, you are contradicting yourself.

    Dark matter is seed of normal matter and of formation of stars.

    No, but we assume that stars formed where there was more dark matter than elsewhere. The (relatively) tight accumulation of stars then led to the formation of small galaxies, which led to the formation of larger galaxies.

    To create gravity (stars) needs not only matter but also energy.

    On the contrary: an interstellar molecular cloud is cooling by emitting radiation so that it can collapse to protostars. A protostar initially converts potential energy to kinetic energy until it is in hydrostatic and thermal equilibrium (outward gas and radiation pressure equals the gravitational pressure). Afterwards nuclear fusion begins in the center of
    the protostar, which is when we start talking about this object as a star.

    Quantum antiparticles ( antimatter) are cold stuff that carry itself

    Word salad.

    enormous pure energy (according to Dirac: -E=Mc^2)

    Antimatter does not have negative energy. That latter is something else.

    Each antiparticle 10^36 times stronger than dark matter particle

    Since we do not know what dark matter consists of, this claim is pure fiction.

    (graviton)

    The (hypothetical) graviton cannot be a dark matter particle.

    and therefore […]

    Ex falso quodlibet.

    / my opinion /
    ^
    unfounded, uneducated

    Shut up and study.

    Not thermal equilibrium, too; that would mean the same temperature
    everywhere, which is not the case.

    (outward gas and radiation pressure equals the gravitational pressure). Afterwards nuclear fusion begins in the center of the protostar, which is when we start talking about this object as a star.
