Could the missing mass in space be invisible because of the difference in Time?

All objects visible to us now are viewed in one snapshot of time, but what we are seeing is variable in time because of distance and there may be more systems that we just haven't seen created yet because of distance and the time it takes light to get to us.

    I seem to have a hard time grasping what you call "missing mass" Mass can be changed to energy, but still there.

    We can see the effects of mass with visible references such as light.

    In time sense, all visible light is from the past, even yourself in a mirror however minuscule.

    Space is vast and the visible limit goes back to the big bang plus the time of its expansion, a very long time indeed.

    The most viable theory as to what lies beyond our visible universe is simply more universe. Light from that, simply hasn't arrived as yet.

    It could be the gravity from Parallel Universes.---(Gravity is the only suggestion we have of "missing mass to begin with) M theory says that gravity is the only "Force" that is shared between multiple " (Mem)Branes"--parallel universes.------So this theory explains both WHERE this extra gravity comes from AND why Gravity is the weakest of the forces---being spread out between universes while the other forces remain in their own universe.

    No time is constant

    Like light

    You cant change that

  • In order to see that there is "missing mass", we have to see the movement of objects in space. So, it doesn't matter how far away an object is and therefore how far in the past we're seeing it, it's still behaving according to what it was and how much mass it contained at that time.

    No. There are many new stars whose light hasn't reached us yet. But we would not see their gravitational effects on others stars either since those star's light takes time to reach us also. Since we do see a gravitational effect from an unknown source, it can't be from new unseen stars. It must be from something that was there when that light left those galaxies.

    If we can't see stuff because the light hasn't reached us yet, then neither will the effects of the stuff's gravity have reached us.

    So no, this does not account for any conjectured missing mass.

    as you wrote,the limits of our ability to observe the universe are immensely far bodies 13 B C years distant,,total mass in creation of this may exclude what lays beyond the barrier of observable light it might be,

    This is true, because a galaxy that appears to be right next to another galaxy may no longer be there. The galaxy may be moving left or right from Earth's point of view, and even some stars or galaxies may have vanished completely. The fact that Earth sees these galaxies in the present time doesn't mean that they are still there because it may have taken the light that makes them visible 100 years or more to reach the earth.

    You can only just see the light of stars, you can't really see planets from a long way away, and you definitely can't see dark matter and dark energy, we don't even really know what it is.

    If by "missing mass" you're referring to what is conventionally called "dark matter", the answer is no. We infer the existence of dark matter from the rotation rates of galaxies we can see, including our own. Therefore, there must be dark matter right here in our own galaxy.

      Oh- So it's not just "out there" - it's "in here" too !
