Interesting.

[annie laurie]

Ping of possible interest.

These guys are telling us that “dark matter” is undetectable and yet they’ve found a whole galaxy made out of it????

[cripplecreek]

Here's to most detailed picture of it to date.

A picture is worth a thousand words ;-)

Captain, Captain, all the stars have gone out!

We detect the effects of dark matter. In this case a regular galaxy has undergone a collision with... nothing. It turns out the nothing is dark matter. Even Hubble shows no stars in the background of the region. It would be detectable by radio frequency, though, which Arecibo did.

Thanks Annie for the ping.

In their own minds at least....

[gcruse]

Oh, sorry. I didn’t realize I was responding to a creationist. It’s easier for some to toss out their rational facilities in favor of invisible people in the sky than interpret radio signals reaching us from space.

We understand, or think we do, the mechanisms driving the birth and death of “real” galaxies.

What forces would drive the formation of dark matter galaxies?

[gcruse]

Dark matter dominated the early Universe too, hovering around normal matter in great halos, concentrating it together with its gravity. As the first stars gathered together inside these halos of dark matter, a process known as molecular hydrogen cooling helped them collapse down into stars.

If this stuff (dark matter) is 95% of the universe, why aren't we having to vacuum it up off our carpets thrice daily?

Aside from that, the question of it (dark matter) actually solving the problem it's supposed to solve is a total joke. Our sun and Alpha Centauri could be modeled accurately, at least as far as scale is concerned, by two dust motes, 1/100" in diameter each, and four miles apart. Gravity plainly can't hold anything together at that scale. Moreover, multiplying the mass of that system by 20 to include "dark matter" would amount to such a dust mote every fifth of a mile. A fifth of a mile is two of those little signs you might notice on the highway; the effective gravitational pull between two dust motes that far away from eachother is ZERO.

You are so very wrong with your thought experiment. It is clear you do not understand physics and your grasp of math is questionable.

[Revelation 911]

are you normally this short tempered ?

[gcruse]

I made an honest reply to a poster’s question, who then revealed disingenuous reasons for asking it. On realizing what had happened, I expressed my distaste for his embrace of ignorance. So sue me.

My college degrees were in mathematics. Of all that coursework, the thing which has been most valuable over the years is basic logic, which is usually the thing missing in junk/democrat science variants ncluding evolutionism, "dark matter", "big bang" and numerous similar items.

oh - I get it - youre one of those fellows who thinks he's "in charge" of his life.

enjoy the illusion

So sue me.

and waste precious time speaking with gracious people - no thanks
