Could Dark Matter in space be....

[cosmictraveler]

ice crystals or ice droplets that develop into larger objects as they coalesce ? Just wondering if this theory has ever been looked intoas yet? Thanks for the help as I will wait to hear the responses. <div class="Discussion_UserSignature"> <p>It does not require many words to speak the truth. Chief Joseph</p> </div>

No, because ice crystals interact with light and therefore would be detectable. <br /><br />What makes it "dark" is that the only detectable effect is it's gravity. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

I thought the detection neutrinos would help solve the dark matter problem. <div class="Discussion_UserSignature"> <font size="2" color="#14ea50"><strong><font size="1">We are born.  We live.  We experiment.  We rot.  We die.  and the whole process starts all over again!  Imagine That!</font><br /><br /><br /><img id="6e5c6b4c-0657-47dd-9476-1fbb47938264" style="width:176px;height:247px" src="http://sitelife.space.com/ver1.0/Content/images/store/14/4/6e5c6b4c-0657-47dd-9476-1fbb47938264.Large.jpg" alt="blog post photo" width="276" height="440" /><br /></strong></font> </div>

If you think about it, this is star fuel and material for planets. But dark matter is even more likely to be composed of burned out suns because galaxies of stars have been here much longer than 13.7 billion years.<br />

So then am I on the right track or is there something else out there that makes up Dark Matter? <div class="Discussion_UserSignature"> <p>It does not require many words to speak the truth. Chief Joseph</p> </div>

As i just read (Nature or Science) neutrinos don't have enough mass. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

That is because comets are so small. The current image of dark matter is that it forms halos larger than the galaxies contained within. Were there that much ice, it would be easily detected, through spectroscopy. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

<font color="yellow">So then am I on the right track or is there something else out there that makes up Dark Matter? </font><br /><br />I feel that there is a definite possibility for your track due to the fact that many stars blow up before they have produced heavy metals, and so they spew into space many lighter materials such as water. But I think dark matter involves more than this, since this would not account for all the effect of dark matter.<br />

I think this is not the case since young large stars may produce water and spew it into space, they also produce many other light elements that are a mix, which is not very visible. We all know that comets are a mix of various elements, but each comet maybe somewhat different from any other. Dark matter is within the galaxy where the stars form and are ignited in a nuclear burn, and eventually blow up or go on to a very long age, in which case they usually have used up their fuel and go through a long cooling process. If we someday find the universe is much older than 13.7 billion years, then statistically there are many more cool stars than hot ones, so there is where we find most of the dark matter.<br />

Dark matter... I have seen documentation of it, and even photographic observations showing its effects. (Some older posts discussed it) One question I have played with is, IF it were possible some particle having mass (what? I don't know ) did travel faster than light... (since, AFAIK if something was possible to have a velocity faster then light we would have know way of detecting, or interacting with it) Maybe we would only be able to observe its gravitational effect. Maybe such a particle could clump together with other such particles? Coalesce into something, making dark matter... I'm out there on a limb.. The problem is of course, nothing having mass CAN have a velocity faster than light... <br /><br />My abstract thought for the day <img src="/images/icons/smile.gif" /><br /> <div class="Discussion_UserSignature"> </div>

If something is moving faster than light it sure as heck isn't going to want to stop to coalesce into such particles... It seems though that this would provide an excellant replacement for dark energy. <br /><br />Dark energy makes up 75% of our universe's energy. It is said to be the force causing expansion. And makes up for the amt. of mass we don't have .<br /><br />Un fortunately your I dea needs one more point to create a reasonable replacement for Dark energy... but there will have to be another thread for that since this is the Dark matter thread.<br /><br />Create a dark energy thread and I'll poost my advice.<br /> <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>

<font color="yellow">I have a creepy feeling though that dark matter and dark energy are to much alike to be different. <img src="/images/icons/wink.gif" /></font> <div class="Discussion_UserSignature"> <div>________________________________________ <br /></div><div><ul><li><font color="#008000"><em>your move...</em></font></li></ul></div> </div>
