There was a program on TV that talks about how 97% of the universe is missing. They say that science can not find it. How ever they can measure it's effect so they decided that 97% of the universe is made up of dark energy and dark matter that they can not find in anyway other then to study it's effect on the 3% of the universe that we do know about.

No, they don't say that science can not find it. They say that science hasn't yet discovered all of its properties. This makes the field very interesting to those who are working in it.

There was this guy one this place on that time that said this and that. Why not list some sources>?

Isn't 95 % quite a bit of universe for science to lose? Do you think that they will ever find it again?

Stars in galaxies orbit around the center too rapidly for the galaxies to hold together, yet they remain together. In addition, there is the missing mass problem. A full 97 percent of the mass needed to hold galaxies together is missing. http://www.pathlights.com/ce_encyclopedia/02-star6.htm


Perhaps the most fundamental gap of all is the missing "dark matter." When scientists add up all the atomic matter that can be accounted for under the laws of physics, there is a huge shortfall between what they know is there and what it takes to generate enough gravity to keep the heavens from flying apart. How huge? They are missing somewhere in the neighborhood of 95 percent.http://www.washington.edu/alumni/columns/march96/universe.html

In recent years, astronomers have found themselves faced with a nagging inventory problem. Received wisdom holds that dark matter and dark energy make up 95 percent of the universe, and ordinary matter, or baryons--the subatomic particles that form planets, stars and the like--account for the remainder. The problem is, the luminous matter detected with the aid of optical telescopes has amounted to a mere 10 percent of the expected ordinary matter, and the baryons inferred by other means bring that total to only 50 percent. http://www.sciam.com/article.cfm?articleID=00048DA2-5C8A-1201-947F83414B7F4945

I thought the point was they have not been about to detect ANY of its properties. They have been able to measure it's effect with some degree of accuracy. But they are unable to directly observe it in any way.

Always wondered how long it would take for a creationist to point this out. Of course the notion that science has actually lost most of the universe is just classic JohnR7 silliness.

But that fact that galaxies should not be stable based on what we currently know about the universe does call into question the foundations of our current cosmology theories. If our universe requires invisible matter to exist then why not an invisible sky daddy?

Now I wonder who will be the first to post a few bible quotes describing dark matter.

This just shows how little you understand about science. Nobody has ever directly observed an electron. Nobody has directly observed a proton. Or a neutrino. Or any other number of subatomic particles. All that we have for these things is indirect evidence. All that we can ever measure are the effects of things.

Well, I personally don't like this explanation of dark matter. Galaxies would just be very different if dark matter didn't exist. Similar structures would still exist, I'm pretty certain, they'd just have different properties.

Anyway, observing the velocity of stars was the first detection of dark matter, but today there is far, far more. Much stronger evidence comes from gravitational lensing, CMB measurements, baryon acoustic oscillation measurements, and supernova observations.

So? Your point is what again?

Do you want me to put you on ignore? Because I am getting tired of people on here being so mean all the time.

And yet, the people who are actually trying to teach you something would never ignore you, no matter what their level of frustration.

Yeah, the point is if Science only knows 3% of that there is to know in the known universe, how can they say that their theorys have any accuracy.

How do you go from "A full 97 percent of the mass needed to hold galaxies together is missing" (or unaccounted for) to "Science only knows 3% of that there is to know in the known universe"??????? :scratch: :scratch:

Well, science could have CLAIMED to know everything and not told you about the other 97%. We're still working on that part. There are some good ideas, and some stupid ones, and we'll keep you updated.

For recent dark matter discoveries (i.e., why we know it's there), check out this paper review http://cosmicvariance.com/2006/08/21/dark-matter-exists/ .

If you call that mean, then perhaps you better not leave your house ever again.
It is like the constant drip of water. There are people on here that are like a bunch of little kids most of the time. They have very little maturity. The result is they chase people away from them. Now if that is what they want to do, that is fine, they have obtained their objective. I am just wondering if that is their objective to end discussion and shut down the board?

Yeah, I am still trying to find the information on that. But from what I remember they have only found 3% of the stuff that is out there in the ground to find.

I see that figure now and then that we only know 3 to 5% of what there is to know. That means 95 to 97% is unknown.

The question has been asked: why does science act so arrogant about what they know, when they in effect do not really know all that much about anything.
