It helps to know the definition of dark matter, since it is much less mysterious than the name would suggest. It simply is matter that we can't see.
The observed rotation rate of galaxies cannot be explained by the amount of matter we can see. Add up all the visible stars, dust, etc in a galaxy, and calculate the gravitational force from this visible matter and see if it can make the outer edge spin as fast as it does. (This is all first year physics stuff btw. Kinda cool that basic principles yield such a crazy result!) The matter we see cannot cause such fast rotation. There must be something in galaxies which does not emit light (dark) but has mass (matter).
Sure, we don't know that dark matter actually is, and there are strange theories out there from MACHOS to WiMPS. But the fact remains - galaxies contain matter that we can't see. Hence, dark matter. It exists, and the basic definition of it really isn't that complicated.
Anthony - well said re science and religion!

Hello,
Toil and trouble. ;-)
All of the available evidence suggests its existence.
I think there may be one or more competing theories, though? Not in wide acceptance. Quantum Gravity, I think? Not sure what it all means.

Certainly, there are competing theories, some quite esoteric. What I'm trying to get at is that in principle it's not so complicated. It might simply be lots of dark planets like Jupiter, or burned out stars that don't emit enough light for us to detect them (MACHOs). Or it could be some crazy weird particles (WiMPS) or even some strange property of "empty" space. But I think what happens is the weird theories get talked up because they're weird, and then people who like to view science as a "belief system" point to the bizarreness as some indication that dark matter is a crazy fever dream with no evidence.
Not so. The evidence is quite straightforward. Something we can't see is exerting a gravitational force in the universe. We don't know what it is, so we call it dark matter.
I was just slightly involved in a MACHO research project, which is the extent of my practical knowledge of this. What I think would be cool though, is if the dark matter effect were some kind of property of space, and somehow related to Hubble's expansion. I can't explain how that would work, because I really have no idea, but it seems like it'd be cool. And somehow logical.

So hey little Rappy, do you want to keep running away from the threads where you're HI-lariously wrong?
Carter raised taxes?

how Chicago is SO VIOLENT and it's ALL the fault of democrats organizing communities?

how it is that you mistake a MICHIGAN lawmaker for a member of Congress and THEN claim that Congress has been around 225 years!!?
http://fireflyfans.net/mthread.aspx?bid=18&tid=52256&p=2
The Congress somehow manages to survive some 225 years w/ out the word 'vagina' uttered on the floor, or in the records, and NOW it's a terrible affront to women to ask for some measure of decency and decorum?

Thank you BDN 
I think we do in fact view this the same way....
Forgive me if I'm putting words in your own mouth, but given the context you put it in, I'd like to further explain where I'm coming from......
Religious people think.... "Wow... there's a lot in the world that can't be explained. Since there is a 2,000 year old book out there that explains it, and my parents believed in it, I will blindly have faith that whatever "bald spots" it covers are true just because".
Science people think... "Wow... as far as we've gotten today, there's a lot in the Universe that can't be explained. We have theories everywhere, but how do we make them cohesive and not fight against one another? Ahhhhhhhh! Dark Matter!!!!
The Ultimate placeholder!
The Ultimate Deus Ex Machina!"
May I submit that Sciences' "Dark Matter" IS Religions "God"......
Nothing more, and nothing less than a convenient "place holder" to explain away all that can't be explained until something better comes up.
Hell... I'm open enough minded to believe that Dark Matter and God both exist and that they're both the same "thing".....
Find any yahoo on either "side" willing to admit that is a possibility.
In the "North", They pondered the same questions about the "bald spots".......

Hello,
I don't think they are quite comperable, and I'll tell you why.
No amount of new evidence or information will cause God to be removed or replaced. It is in the nature of religions (those where God is featured) to make the questioning of God a Bad Thing.
However, new evidence and information can cause Dark Matter to be removed or replaced. It is in the nature of science to accept the questioning of assumptions.
Science is the process of seeking answers. There is often a hope that the answers found will help solve problems, though science itself is merely a process for understanding the universe.
Religion (at least those centering on a God) is the process of believing an answer that has already been given, and trusting in that answer to solve problems. There is no quest to understand the universe in religion, only a quest to follow the will of the creator. This will is usually outlined in an immutable document.
I think there is more room for growth and change in Science. It's Searching versus Believing, to my mind. I say this as someone who believes (religion) but refuses to stop searching (science.)

Hey Anthony....
You're right, and you're wrong.....
Ask any "Old Testiment" believers what they think about "New Testiment" believers.....
My dad was Agnostic and my mom was a "twice a year" Catholic. I grew up celebrating the good ending to Footloose. The Simpsons' Ned Flanders would consider the ending to Footloose a porno movie.
God has ALWAYS evolved..... just ask the Lent practitioners who eat Fish on Fridays.....
Old Testiment God would have thrown a lightning bolt up their ass for that....
Most of your observations otherwise, if not all of them, I either agree with fully or contemplate all the time on. I have no answers, nor will I EVER have any answers that would convince anyone but myself to believe differently. I'm an Agnostic, like my father, but I truly want to believe that there is a reason for all of this and there is an underlying excuse for how horrible people in general are.
We're supposed to be sentient beings, no matter if we were "made" or just an accident over billions of years, but here we are......
We suck....
Humans suck...
We are the worst thing that has ever happened to this planet, and "Dark Matter" forbid us to ever find a way to colonize our shit on other planets.
I'm sure I sound crazy here, but I really hope that we're living in a world where all the 6 billion people who were neither rightous enough to find Nirvana nor depraved enough to find Hades are just floating here in limbo. To us, it seems like life as it should be, but for all of us here, it's our final test.....
What will we make of it?

And then Jack thinks... Oh, wait. No, he really doesn't. Jack has decided that thinking big thoughts makes his brain hurt, so he doesn't think, he drinks. Yes, he's really advancing humanity, isn't he?
