Elusive Dark Matter May Be Hidden on Earth
Elusive Dark Matter May Be Hidden on Earth

Scientists are hot on the tail of one of nature's most elusive substances, the mysterious dark matter that is thought to make up the bulk of the universe. Many scientists think dark matter might even be hiding right under our noses here on Earth.

Dark matter is especially tricky to find because of its dark nature. In fact, scientists don't know what it is. It doesn't emit or reflect any light, so the most powerful telescopes have no hope of spying it directly. It has been thought to exist since the 1970s based on observations of gravity's effects on large-scales, such as among and between galaxies – regular matter can't account for the amount of gravity at work.

And dark matter doesn't often interact with most other matter, scientists theorize. One idea is that it flies right through the Earth, your house, and your body without bouncing off atoms.

Some scientists have taken to underground searches in hopes of catching just a few out of the multitude of dark matter particles in a rare instance of actually bouncing off of a regular particle.

"They're just streaming right though us, and every once in while there's an interaction," said Angela Reisseter of the University of Minnesota, a member of a project called the Cryogenic Dark Matter Search (CDMS). She spoke this month at the meeting of the American Physical Society in Washington, D.C.

1. Why does the image of W searching the oval office pop up in me mind?
"What? No WMD here? How about Here?"

4. Sounds like Emperor Palatine has perfected his Star Wars dialog:
'Something, something, something, DARK SIDE!' Tip o'the hat to Seth MacFarlane & The Family Guy.

The way the article is written, it's practically begging for ridicule from non-scientists: 'It has been thought to exist since the 1970s...' We know the author meant that the theory has been around since the 1970s, but the syntax suggests that some scientists believe dark matter itself has only been around since the 1970s.

5. Even the title is somewhat goofy
Elusive Dark Matter May Be Hidden on Earth

Hidden like an immunity idol on survivor? Hidden in a cave, under a rock, behind the toilet brush under the sink?

6. Yunno, there's a certain bronze-age sky deity who likes to hide things
Goes by the name 'Jehovah' or 'Yahweh,' I believe. He likes to hide dinosaur bones deep within geological strata, making the gawdless, secular humanist scientists believe they're millions of years old, when in fact the entire earth has only been around for 6,000 years. He plays pranks on the heathens just to fuck with their heads and to test the faith of adherents. Maybe this Sky Daddy has hidden a cache of dark matter in a dumpster, where an unlucky homeless person or dumpster diver will find it, open the container, and have his head taken clean off. Much heavenly hilarity will ensue.

7. Yes, I think I've heard that story.

Although in the version I recall the homeless guy is transported by the dark matter into a multiverse where he gets lost until a cat tells him how to get home.

11. Well, we don't know about it since it's only been around for 40 years. "has been thought to exist
has been thought to exist since the 1970s"

LOL

8. It's the soupy goo of nothingness in which all things float.
Does that help to clear up the matter?
