SIOUX FALLS, S.D. (AP) Scientists hoping to detect dark matter deep in a former South Dakota gold mine have taken the last major step before flipping the switch on their more than $300 million experiment and say they may be ready to begin collecting data as early as February.

What's regarded as the world's most sensitive dark matter detector was lowered earlier this month into a 70,000-gallon water tank nearly a mile beneath the earth's surface, shrouding it in enough insulation to hopefully isolate dark matter from the cosmic radiation that makes it impossible to detect above ground.

And if all goes as planned, the data that begins flowing could answer age-old questions about the universe and its origins, scientists said Monday.

"We might well uncover something fantastic," said Harry Nelson, a professor of physics at University of California, Santa Barbara and a principal investigator on the Large Underground Xenon experiment. "One thing about our field is that it's kind of brutal in that we know it's expensive and we work hard to only do experiments that are really important."

2. I don't know why

But I keep picturing Karl Rove floating in dark 70,000-gallon water tank under the ground and the meter just jumping like crazy.

Hope the experiment finds it.

4. Blinded by the light

If you want to find matter that's dark I guess it makes sense to go where the dark is.

5. what they covet most

After that, the scientists involved hope to start seeing what they covet most: something they've never seen before.

6. I'm not a scientist, man...



...but as I understand it, even the existence of "dark matter" is theoretical.

Modern Science Inc is desperately trying to find something that explains why, under close examination, all matter appears to be an illusion. "dark matter" is that god-like essence that, despite a makeup of atoms and molecules an object still appears solid.

8. the SD mine lab is looking for direct evidence of Cold Dark Matter

There is overwhelming indirect evidence of CDM. CDM is made of teensy particles that don't interact with light and it makes up most of--about 4/5ths of all the matter in our universe. An example of indirect evidence of CDM is the gravitational effect it has on matter we can see behind it called the lensing effect. It is as if we are looking at distant galaxies through a clear lens or eyeglass that distorts our vision. Here is a little vid of it:

11. Wow. We actually spent money on a science experiment?



Hopefully it'll find something.

13. Yes! We can finally get scientifically sound evidence that ...

The world was created in 7 days and its 5000 years old!
Fer shure!
God wouldn't let us down by sending us false evidence.
He loves us too much.
Cuz we are so lovable.

14. Wait a sec...!!??



Are you saying modern science is going to endorse modern religion?

Two great social myths joining forces...??? What are they up to...????
