    ^^ Wow. That's seriously interesting. Amazing. This 'dark matter/dakr energy'...is that like black holes?

    Thats String Theory. Its the leading candidate right now for a grand unified theory thatll explain everything.

    Dark matter isnt black holes. They know black holes exist and have found a few. Dark matter is different and they dont know what it is.

    If they take all the known matter in the universe it still wouldnt be enough to account for the gravitational effects we're seeing out there. Our own galaxy, if you took all the visible matter in it, would not be enough to keep the Milky Way together; way less than half actually. From what we can see, we should be flinging apart out into the universe. So obviously there is a lot more matter out there that we cant see but yet there is more of it than visible matter.

    mac's pretty much hit it on the head...

    unfortunately, no, black holes aren't it... black holes can actually be detected by a characteristic radiation pattern (stephen hawking recently showed that they actually 'evaporate')... the dark stuff is dark in every sense of the word... it's invisible and detectable in only one way - gravitational lensing... a good wikipedia article is here, but the gist of it is that matter bends light around it like a lens...

    the canonical description of a massive body in space is to visualise a bowling ball on a sheet of rubber... the sheet of rubber bends a lot close to the ball, not so much the further away you go. now, start far away from the ball, and shoot a marble just to the outside of it... the marble will roll in a straight line until it nears the ball, then it will curve around the dip the ball has made in the rubber, then as it clears the dip, it will resume travel in a straight line... gravitational lensing around dark matter is the same thing, except the marble is a light wave, and the bowling ball is invisible :p...

    this is how they found the stuff... they saw the light bending, but there didn't seem to be anything there to make it bend! using precise measurements of the bending combined with accurate models of the motion of galaxies, you can actually reconstruct a map of the mass distribution in the universe, and it's totally mystifying, because we can only see bits and pieces of it...

    Dude, you have no idea. Thats what facinates me so much about astrophysics. Just trying to comprehend the size of our galaxy alone is staggering!!

    Example:

    The speed of light is 186,000 miles per second. You could orbit the earth 7 times in a single second at that speed.

    The nearest start is Alpha Centuri and its 4 light years away. That means if you were traveling at the speed of light it would still take you 4 years to get to the NEAREST star.

    Thats a single star yet there are billions of stars in the Milky Way which is several hundred thousand light years across. That means at the speed you could orbit the earth 7 times in 1 second, it would take you 200,000 years to cross the Milky Way!!!

    The nearest galaxy, Andromeda, is 2,000,000 light years away!!!!!

    There are billions of visible galaxies out there are grouped into clusters and there are billions of known clusters all billions of light years apart!

    and that's why we use megaparsecs :p 1MPc = 3.32 million light-years, and the numbers are still incomprehensibly large... and yet, we also deal with scales down to 10^(-31) meters, the approximate length of the superstrings mac mentioned...

    What did I start......

    And FWIW I don't subscribe to the "You can go forward but you can't go backwards"
    theory. Most of this stuff is pure speculation and we have no way to prove most of it
    yet. But if you can go forward then you get into quantum dimensionality which I am
    not a beleiver of...

    It sure is neat stuff to wrap the noodle around though...


    Oh yeah, when I fire up my Line Array's for the first time, I think they are going to
    create a magnetic field large enough to warp space time in a localized area! :D

    "special"? :D

    red230 - i hear ya on the speculation bit, that's why i qualified it with 'as far as we understand time and space'... pretty much all we know is that quantum bits are real things, not illusions, and that gravity is an **** for not bowing to our wishes and reuniting with the other forces... beyond that, strings, m-theory, and so on, it is all very 'theoretical'... like quantum dimensions (the 6 or 7 dimensions above and beyond our normal 3.5-4 dimensions), superstrings are just a way of describing the problem that yields the correct answer... doesn't mean it's the right way of describing the problem...

    a good analogy i heard once:

    an alien scientific task force decides to study earth, and the first phenomenon they hit on is a pro soccer game. these aliens, however, have the peculiar INability to see simple black and white patterns - their brain simply does not register them. so, the aliens study and study... they see the main players running in clumps and patterns, occasionally doing strange dances... sometimes one of the people at the goal will leap into the air, and half the crowd erupts each time this happens, but it's not always the same half of the crowd... they'll hear the occasional whistle, and the players will back up into some formation... so on and so forth...

    so the big smart scientist aliens derive a huge set of complicated rules that perfectly describes every soccer game they've seen, and is completely correct from their point of view... then, one of the junior scientists proposes two radical things - that there is some particle that they cannot see, around which the game is focused, and that there is an invisible force governing some of the noises and patterns in the game... having postulated the existence of the ball and referee, they go back and re-analyse the game, and derive FIFA's rule book :p

    in the same way, we are at the second step as far as quanta go, but probably very much at the first as far as superstrings go...

    We HAVE been visited! Look up John Titor on the net :D

    Any guy that time travels in a Corvette has to be legit my friend! And I don't
    care what Stephen says, I respect his opinion and I think he's a great guy and
    I can listen to his speeches for hours.... But his opinion (however highly
    educated it may be) is not fact.
