Does anybody have any personal theories about what dark matter is. Apparently there is a lot of mass in the universe that remains unaccounted for, so the scientist came up with dark matter.

I’ve heard some say it is nuetrinos. I’ve read about theoretical negative mass/energy.

Dark matter sounds to me like scientists who are unwilling to admit that they haven’t a clue how the universe works and their paradigm is invalid. "Let’s make an offering to the volcano god so he won’t get mad and kill us", sounds about as scientific as this.

So, to clarify things, I don’t believe in our current scientific paradigm or volcano gods. I think that we have a lot to learn and I always laugh when I here scientist criticize those who have religious faith.

I remember hearing a special on some of stepheen hawkings theoreis and one of the things that seemed to stick in my head was that he mentioned it was apossibility that the universe has a
life span so from this I concluded that dark matter is a source of raw materials/building blocks that nature/God uses to build new solar systems for the life span of this universe

As you know dark matter is really that "x-factor". When we observer the stars movements sometimes there movement is not completely static. From Newton & Kellper we learned a lot like the principals behind planetary motion. Then we got the replacement from Einstein using General Relativity. When we do the math the star movement we see of some of the stars does not factor out or equal what we see.

So we deducted that there has to be some other force as an extra variable. This extra variable turns out we think to be so called "dark matter".

So let’s imagine two stars going around a large gravity source. Not only that but lets pretend that dark matter is in the center as a result the two stars that are not the same distance would be pulled equally from the dark matter. If we think about it that does not fit. The best conclusion and that has been verified by observing the heavens and there motions is that its spread all around, mainly in-between the stars in the sky. So the star closer to the gravity would have less dark matter pulling it. (Or the star that’s farther away would be pulled on more)

This point is a starter for us to go into what it might really be. So scientists then began to see what kind of particles would fit the variables at hand. One particle that may fit in it is the neutrino. This particle has no mass, it does not decay [not easily it would take a very long time], and has weak interaction. It fits the variables at hand we think.

By the way it is called dark matter because we can not see it and for the fact that neutrinos fit the bill that make them up.

Dark matter like you said we don’t know that much about. We really don’t. Like I said it is the "x-factor" [one time Marthom said that and I like that description].

From the recent WMAP information where a satellite’s objective was to record microwave radiation that originated 13,000,000,000 light years away! (So we received this microwave radiation 380,000 years after the start of it all . . . The Big Bang!)
We found out that
4% Matter
23% Dark Matter
73% Exotic Dark Matter
Exist in the universe (or at least we think)

The thing that is interesting is that 4% is matter and that’s what we know a lot about, but when it comes to dark {- the majority} we don’t. This just shows us how little we still know in the grand scheme. One thing that the data collected impels is that the inflationary model to the big bang is the most likely. For one (and not to go on about this model too much) is that for it to really work it would require the existence of dark matter.

I have been a supporter for the inflationary model and now I think it’s almost completely verified (the general idea of it not looking at the very detailed things). Dark matter would if you think about it would be needed for this ’inflation’ to occur in the universe.

Things like neutrinos (like I stated), black holes, brown dwarfs, white dwarfs, exotic particles would have to be connected in the grand scheme in dark matter. So I think we really should look at things like negative energy more in the scientific community. Then I think we would in the long run get a better idea of what it is not just that it is the "x-factor".

The main problem I have is that this dark matter would have to exist every where in the universe, but within our scope of detection.

We have never verified the existance of a nuetrino (but I do not doubt they exist). If they do exist, there mass is incredibly low, on the order of 10^-60 kg. That means that there cannot possibly be enough of them to make a difference this big.

If there was this massive dark matter that we cannot detect, we should be able to detect it presence by how it affects other things (like us). But we cannot, in the near earth universe everything seems to be accounted for.

This just seems like wild speculation to me. I have talked this over with professors of physics and they have no real explantation. Dark matter is just a god for scientists to believe in.

Continual acceleration can not be accounted for by the assumed big bang because that would require a contiunually increasing force of propulsion or attraction for creating acceleration, how else can it acceleration otherwise? And of course the big bang was a instantaneous event, not a gradual and changing one.

What makes them thing dark matter is matter to begin with? What makes them think it has mass?

Inflation is not continuous acceleration but continuous expansion of space/time (or so the theory goes). Is that what you were talking about with continual acceleration?

The speculation of dark matter exists because there doesn’t seem to be enough mass/energy in the universe to account for everything in our theories of the universe. So, the theory of dark matter is built upon the premise that it contains matter.

I don’t think that words like instantaneous or other words that imply time contraints can be used to describe the big bang, since theoretically time did not exist until after the big-bang (which was the bang that created space time). Also, space and time were not the same shape they are today.

"The speculation of dark matter exists because there doesn’t seem to be enough mass/energy in the universe to account for everything in our theories of the universe. So, the theory of dark matter is built upon the premise that it contains matter."

This is exactly why I say theorizing is irrational. They want the world to conform to their theories, their ideas, instead of actually acknowledging the facts. Old human faults and weaknesses again, arrogance and insecurity.

I looked at this, and it basically says that there is mysterious dark matter. We still have no clue what this is (or if it really exists). I think there is a strong chance that we do not even understand the nature of the universe as well as we think we do.

I read a national geographic about that and the message I got was that dark mater is space. this makes sence when you think about a black hole. The way I think of black holes is that they are so dense and have so much gravity that they rip the space around them, or dark mater. the way my "friend" thinks of it is that its some sort of magic portal that stoppes time and tranports you to another galixy. not true.

Perhaps dark matter is the stuff that doesn’t quite fit in with what the LOP (laws of physics) saw it can be, ripples from an extra-dimensional source? Or maybe the LOP aren’t as constant as we’d like to think, its matter Jim, but not as we know it.
I quite like the extra-dimensional idea, it explains expansion as well. Imagine what we consider spacetime as an elastic net and other dimensions being the poles underneath it, with enough matter and energy to be expanding, so pulling the universe out.

Perhaps there is some sort of colony of silicon-based thermosynthetic lifeforms living in the magma, with the ability to take the immense amount of energy to hold together their unstable organic chemistry. But without the rare mineral salts found in the offering they lose cohesion and die, hence upsetting the balance of the magma and causing an eruption.

More religeous zealots trying to link religion to science.
