Astronomers: Dark Matter Guides Universe's Structure

That is one funny graphic. Al Gore’s secret global warming model, perhaps?

[mjp]

so is dark matter wimpy, neutrino-y, or axion-y?

The nearest objects are in blue and then follow the order of the spectrum to the most distant objects in red.

...we are incredibly tiny....

So is everything, relatively speaking.

...it also offers equally compelling proof that the universe is expanding and will continue to do so, rather than at some point collapsing back in upon itself as some astronomers have theorized.

Ouch, I guess the haples naturalists have to go with the multi-verse thing now.

Thanks rdl6989.

And recently it's been observed that dark energy slows down the contraction of large galaxy clusters.

Because we can see the far galaxies I suspect that this “dark matter” is in fact invisible matter with mass?

It's dark because it doesn't interact with the electromagnetic force, thus it doesn't emit or absorb light, but it does have mass.

Hi SunkenCiv,

Can you please add me to the string theory list?

Thanks!

As a matter of fact, dark matter, medium-dark matter, or even light-dark matter is pretty easy to comprehend.

At least in comparison to wondering what is going to hold this country (my galaxy) together with the hundreds of trillions (maybe even light-years) worth of funny money being printed by the current administration.

Maybe dark matter (or dark anti-matter), in some parts of the universe, pushes things apart instead of holding them together?

A 10-year study of 100,000 galaxies close to our own offers compelling proof that long-hypothesized "dark matter" does exist and is in fact a guiding force behind the structure of the universe, a team of Australian, British, and American astronomers revealed this week.

Ever wonder why scientists give Christians so much crap when a buttload of their theories demand just as much if not more FAITH?

If you cannot PROVE it and still believe it, you're taking it on faith.

I never liked ‘fudge factors’. Dark matter is one of them. The assumption that the gravitational force and the rate of time has remained consistent throughout the lifetime of the Universe should be scrutinized more carefully IMO. In short, question the model that doesn’t fit without mysterious, unseen additions.
