ooh! They finaly verified data from 2000. They have indeed discovered an invisible galaxy in space. Opening up new research into dark matter.

In fact, they now believe it could be possible that there are more invisible ones out their than visible ones.

    i don't think it's that surprising that there are bits of material floating through space that we cannot see. since we can only "see" objects if they emit or reflect some sort of energy, such as infrared, visable light, xrays etc, any objects that are not energized enough, like chunks of iron or rock, will be invisibie to us, and therefore "dark matter". so all they've confirmed is that they found a huge pile of inert debris flying through space...

    <a href='http://www.space.com/scienceastronomy/astronomy/dark_matter_sidebar_010105.html' target='_blank'>Iron</a>? Dark Matter is really just matter that doesn't exert any known electromagnetic energy, and seems to only really be detectable by measuring its gravitational influence on nearby celestial objects. Iron and space dust do actually give off energy (optical and other), while dark matter doesn't - and we've known about them for a long while, in fact, dust clouds create some of those beautiful pictures like

    <img src='http://nvo.gsfc.nasa.gov/astrodata/gifs/orion-horsehead.jpg' border='0' alt='user posted image' />
    The Horsehead Nebula on the belt of Orion.

    Notice how you can't see stars behind the 'horse head' (although this really isn't the best picture; just use google and type in "Horsehead nebula").

    while iron and space dust CAN give off energy, it also can sit inert and NOT give off energy. Whether or not it gives off energy depends on a number of things, cause it will only give off energy when it's particles are in an excited state. if it is absorbing energy from somewhere, like it's bombarded by solar wind particles, then yes it will give off energy. but if it's just sitting there in space by itself, its not going to give off anything. energy doesn't come from nowhere you know. e=mc^2, so either engery is transferred to it, or some mass is destroyed, as in through fusion. if it's not absorbing energy, it'll give off all it has to become stable, then it will give no more. then it's "dark matter" cause we cannot "see" it, but can infer it's presense by its gravitational influence on objects that we can "see".

    No, Iron and dust will constantly give off energy in some foror other. They will absorb energy and then give it off in a different form to remain neutral; because as you so eleoquently put it: E=mc^2 (which isn't the full formula, but what the hey), it can't just absorb starlight and do nothing with it... Dark matter on the other hand doesn't seem to absorb, reflect or alter electromagnetic waves (although it seems they detected it with a type of radio wave measuring the gravitational changes).

    It's just like how stuff on Earth absorbs sunlight, and then gives off infrared light (optical light and UV -> mostly infrared emmision.

    Not to mention, by "invisible", they mean "see right through it". You can see the stars behind that dark galaxy, whereas you most definitely can't see through a similar sized chunk of iron. <!--emo&;)--><img src='http://www.unknownworlds.com/forums/html/emoticons/wink-fix.gif' border='0' style='vertical-align:middle' alt='wink-fix.gif' /><!--endemo-->

    If something is invisible in a spacial sense, ie, it gives out no discernable type of radiation, then surely if something behind it is "visible" then it would either be hidden by the "invisible" object, like something being fully cloaked (I know it's not the same, cloaking is a refraction of light, not an electro-radioactive shield) then the visible object would become temporarily invisible too, as they wouldn't be able to detect its radiation. But if its visibility got distorted somehow, by passing through the EM-filter, if you will, then it would have a "net curtain" effect, or a fish-eye lens affect, as it would be distorted by the object in front. Then anyone could compare the expected result with the actual reading, which would then tell them "Hold up a second lads, there's something in the way of this..."

    OK, they'll be about several million miles of space to search, but they would know that something would be there by following a trail of distorted radiation emissions. Get me?

    Hrm... well I wonder what would happen if dark matter came into contact with energetic normal matter.... if dark matter was inside a gas cloud, the energy pattern might leave a sillouhette (spelling.. I know) of the mass.

    Inert material floating in space is one thing. Its another thing when there's a galaxy worth of it. This would mean that an entire galaxy would have to be extinguished. How or why that happened is what concerns me.

    Hang on hang on hang on hang on. Proper invisible? Dark matter or no, I'd love to hear the explanation of where the photons are going. It's definately not just that it's dark, therefore blending in with the inky blackness? You can definately see stars through it?

    But since the universe is a curved plane, when you travel in one direction you will eventually return to your origin. There's a trippy thought for you.
