"I'm not sure what it is that makes it more appealing to break general relativity and say that all these huge observations are wrong, versus 'there's a particle we can't see."

Worth repeating!

Well, there’s protons, electrons and neutrons making up Normal matter.

Normal matter is supposed to be a smaller part of all stuff according to some of these scientist.

Dark matter, is in abundance everywhere it seems, per some of those same scientist. Kinda like Stupidity.

Maybe the dominant particle of dark matter is morons ... it would explain a lot.

I guess what the article is asking, does Dark Matter matter?

Viewed an interesting utube last eve on antimatter. Said that at the moment of the big bang, there was equal amounts of matter and antimatter, and then discussed the various scenarios of what happened to the antimatter.

Other than the center of the milky way, there apparently is little antimatter in its stars and planets. Probably the same in the galaxies of the visible universes.

Perhaps there is a companion universe comprised of all the antimatter. Where that one would have a smattering of matter, just like we have antimatter here.

It’s my understanding that dark matter and anti-matter are not the same thing. What’s anti-matter?

If you go back to high school physics class, you may remember that the more mass something has, the greater its gravitational pull. If galaxies were only made up of the stuff we can see, there wouldn't be enough gravity to keep them together (scientists reckon), much less to keep the stars in the sparse outer edges orbiting just as fast as those in the center (scientists reckon). In fact, scientists reckon that normal matter makes up less than five percent of the universe. Dark matter seems to make up a whopping 27 percent. (The rest is a mysterious force called dark energy.)

"Scientist reckon".

Maybe scientists reckon wrong.

If “dark matter” exists why isn’t my lawn covered with it?

There are folks who have argued, convincingly, that there could be a large density of small mass black holes that could account for the missing mass.

A metaphor:

Dark matter is that cousin whom you hardly know he’s there even when he’s there, which is somehow most of the time.

Antimatter is another cousin who is hardly ever around but when he is he’s loudmouthed, destructive, and even violent ... expect the cops to be called.

Antimatter meets matter. Kablamo.

Darin matter is something else. It is the name scientist give an unknown feature of ours and other galaxies that keeps them from spinning apart. Vera Rubin discovered that the stars in the galaxy don’t orbit the center like the planets in our solar system orbit the sun at different speeds. The Galaxy for the most part spins like a phonograph record as if it were a solid the only way this could happen is if there was considerably more mass that is unaccounted for. Now dark matter is physically visible as the mass warps space enough to cause stars in the background to appear elsewhere by gravitational lensing.

I knew a guy that built the best gravity meters in the world. He was hired by the military to try to measure “anti-gravity” as a solution to why the missiles weren’t landing where they were supposed to. This was years ago, and perhaps before the idea of dark matter was invented.

He couldn’t measure any anti-gravity (too difficult in actual on-site field experiments) - but he didn’t discount the idea. Although I guess that dark matter is the opposite of anti-gravity. Although the idea of anti-gravity may account for the variations that they observe?

All of the other natural forces (magnetic, electro-magnetic, etc.) have positive and negative attractions, so why wouldn’t gravity?

LOL, your use of 'reckon.' But I reckon you reckoned wrong. Ditto your other use of 'reckon.' They did much more than "reckon" how much gravity it would take to keep the stars together, and the outer stars orbiting just as fast as the stars in the central region of the galaxy.

Because we found some stuff we didn’t know what it was so we called it Dark Matter - we called it Dark Matter because it exists, it exists because we called it Dark Matter - QED.....

Dark matter is matter that travels faster than the speed of light.

Your welcome.
