    Default dark matter



    Hi all I am a newbie & wish to know more about dark matter. It's properties (if known) & the effects it has on various celestial bodies (also if known) and or its effects on humans etc.
    That may sound like a strange question coming from a beginner but I needed to start somewhere on this forum. lol

    Remember that Dark Matter is theoretical. It is postulated because according to our current cosmological and physics theories there has to be more matter than we are able (at this time) to detect in any manner other than its apparent gravitational effect.

    So at this time we really don't know much about it other than if it exists (seems likely), it has a very significant gravitational influence on/in our universe.

    OOOOOOOOOK! Thanks for your answer. While it maybe theoretical at this time along with its influences on various gravitational aspects, I am trying to tie it in with some aspects to our planet's existence along with other heavenly bodies. Guess I'll have to wait till someone somewhere discovers the answers.

    Well, assuming it exists (which I do, with skepticism), then without dark matter our galaxies and, to a large degree, the objects which make up those galaxies would not exist as they do today. I don't think anyone knows how things would be - but they wouldn't be as they are today.

    It'll be interesting to see how it all sorts out. There are recent studies which indicate that the amount of non-dark matter has been underestimated, and I think that further discoveries may make the need for the postulated dark matter to go away. It is possible that an alternate cosmology will be found to explain the universe more accurately - and without demanding the need for dark matter. There is also potential for the Large Hadron Collider to find good evidence for dark matter and help us understand what it is.

    Who knows?

    But the key is to remain skeptical of all theories and beliefs.
