Good Lord...it’s Bill and Hillary.

If only their telescopes could look to the end of time, I’m sure they would still see them.

Cool article. We need an Epoch of Reionization in DC.

Well that's just great. Another climate for evil humans to ruin. 👹🚀❄️💨

One again dark matter is not observed. It’s inferred because without it mainstream theory becomes bogus.

What’s Dark Matter made of?....................

The first picture is Jesus giving the Father (whose hand and sleeve are visible) a high five.

Or is that a hight 10?

A spiral (to me) always suggest something being sucked into a vortex.

Very few galaxies look like they are exploding outward

[Mr. K]

dark matter.

[Red Badger]

They ARE being sucked into a black hole! In the center of the galaxy...................

[Red Badger]

I could see that!..................

[Red Badger]

Dark Matter matters....................

Dark matter is a placeholder. It’s sort of a shorthand way of saying that there is more mass in the universe than what can presently be observed.

[Red Badger]

Like ‘gravity’, it’s just a word for something we don’t understand...............

[linear]

I think gravity is relatively well-defined at this point. ;) Dark matter could be one thing or a combination of things. Or maybe our math is just wrong. :)

[Bloody Sam Roberts]

"Astronomers Spot"? Dark matter? Is that the stuff that 'astronomers' and cosmologists told us exists but it can't be seen?

So...how was this "spotting" done?

[Red Badger]

Gravity can be measured.
Gravity can be predicted and characterized.
Gravity can be identified.

But it can’t be explained.

Same with magnetism...................

[Red Badger]

Inferred spotting................

[GoldenPup]

Good Grief! Big Bang, little bang, gang bang.

Just Give it a Rest!

No one can say. But as it’s gravitationally interactive, one would expect to see huge globules of the stuff crashing into visible bodies throughout the cosmos. Yet no such interactions are seen. Thus it seems but a device to explain something not yet explainable.
