    dark matter ,what are it's entity or properties.

    If lightning like nature act happened in space ,
    what will be the way of existence of dark matter at that particular position in space :
    before lighting action
    During lightning
    and after lightning

    and also , Can dark matter be labeled as dark ENERGY ?

    Apart from the fact it has mass and does not interact electromagnetically, not much is known. It's distribution can be mapped from its gravitational efects. This also tells us something about its likely velocity.

    It would have no effect because, as far as we can tell, dark matter does not intereact electromagnetically.

    and also , Can dark matter be labeled as dark ENERGY ?
    No. Dark energy is a completely different concept (related to the apparent accelerating expansion of the universe).

    I am probably going to be yelled at for this but I think they are one in the same and dark matter does interact electromagnetically with normal matter. What if this dark energy is actually dark matter that is just electromagnetically pushing against our normal matter and that is what is causing the acceleration of the universe. It could also be what is gravity or what we think of as gravity. I dont think gravity really exist. We cant link it to the strong force or weak force or electromagnetism. Personally I think what we think of as gravity is just the pressure of this matter we cannot see or detect pushing down on us.

    Excellent first post!
    It's always good to establish yourself as a crackpot as early as possible: that way we can easily dismiss any further posts from you.

    Haha of course. Gotta start somewhere Im not a crockpot, just trying to think outside the box.

    The word is crackpot.
    And "think outside the box" is a typical crackpot rallying call.

    Any support for your claim that "dark matter does interact electromagnetically with normal matter"?

    No. Completely different things, proposed to explain completely different effects. Just because they both have "dark" in the name doesn't mean they have any connection with each other (or with Star Wars).

    dark matter does interact electromagnetically with normal matter.
    Again no. Pretty much by definition.

    What if this dark energy is actually dark matter that is just electromagnetically pushing against our normal matter and that is what is causing the acceleration of the universe.
    Because that is not how it works.

    I dont think gravity really exist.
    Then what keeps you in your chair.

    We cant link it to the strong force or weak force or electromagnetism.
    So what; that doesn't stop it existing.

    Personally I think what we think of as gravity is just the pressure of this matter we cannot see or detect pushing down on us.
    Welcome to the 17th century.

    just trying to think outside the box.
    Not sure what the point of that is if it means you are totally wrong.

    Maybe worth noting that there are real, scientific attempts to relate or even unify dark matter and dark energy. For example:

    Haha ok ok. Definitely not the right place or time to post this. Ive just been thinking a lot lately about how the next big step in physics is to link the laws of the big (general relativity) and the laws of the small (quantum mechanics). It seems to be the next big step. I just started thinking why are we trying to link the two. Why not try to think small and what would cause what we see as gravity at an atomic level. We only call it dark energy and dark matter because we don't know what it is. In essence that is the definition of dark matter and dark energy. We don't know what it is or what causes it haha. I know we don't think its the same or categorize it as the same but that's not to say that dark energy couldn't somewhat be caused by dark matter. Whatever, someone has probably already thought of that before. Not trying to cause a riot just a discussion.

    Also it doesnt help I am talking about two completely different discussions so fire away lol.

    Dark matter and dark energy are not in the same league. Dark matter is most likely particles that will be detected. They 'make sense'.Dark energy is much more enigmatic. It makes no sense according to any accepted physics models. All is speculation. Lawrence Krauss, a leading theoretical physicist doubts dark energy will be explained in our lifetime, if ever. The door to Multiverse theory opens wider when dark energy is discussed. It is not even known if dark energy, if magically explained by some alien intelligence, would make sense to us as it may not be subject to mathematical theory...it 'just is'.

    Its amazing how the incredibly big (like the multiverse theory) or the incredibly small (like what makes up sub atomic particles) is so hard to even wrap our minds around.

    Because there are scenarios where quantum gravity plays an important role, such as a gravitational collapse.

    Why not try to think small and what would cause what we see as gravity at an atomic level.
    It is rather easy to write down a quantum field theory for gravity - unfortunately it turns out that such theories are not self-consistent, and contain infinities; we are therefore continuing to find a more correct approach.
