Dark matter matters.

[Red Badger]

[rightwingcrazy]

What matters is that we’re still in the dark about dark matter. Consider the gravity of that.

[FLT-bird]

Anytime you hear the word “dark” in science, you should immediately be suspicious.

“Dark matter”....”Dark energy”.....maybe neither exist. Maybe our current understanding is simply flawed and that’s why our models don’t work. As brilliant as Newton was, he got some things wrong as Einstein pointed out. Well as brilliant as Einstein was maybe.......

[An Appeal to Heaven]

Or maybe it doesn’t exist at all. After all, there’s only indirect evidence for it, right?

[Reily]

You’re always missing physics in simulations that’s why its a simulation !

[brownsfan]

We are so limited in what we know, and what we can measure, it’s like trying to teach a chimpanzee calculus.

[blueunicorn6]

“We don’t know what it is.”

Huh.

[Bratch]

[I want the USA back]

I’m still waiting for proof that there’s matter that is undetectable, that doesn’t reflect light, and that doesn’t just satisfy some equations that would not work without it.

[Altura Ct.]

It should go without saying...but...you know this is racist!

[Getready]

Is dark matter and dark energy the epicycles thingee all over again?

[Raycpa]

Be light, and there was light.

[no-to-illegals]

What is known fills one page in one book. What is unknown fills infinite volumes of books in infinite libraries

[wildcard_redneck]

Has any scientist ever proposed that our universe is expanding faster over time because there is unseen matter that it is falling towards that has not been detected yet?

[ShadowAce]

I think the simpler explanation is that we don’t fully understand gravity yet.

Thanks Red Badger. Article author Michelle Starr?!?

Hi.

I’m going to solve the puzzle of the universe.

No, it’s not E=mc2 it’s that the whole universe is binary.

Matter, antimatter. On, off. Is, isn’t, light, dark...etc.

True, false.

God ordered this way.

“[dark matter] does not absorb, reflect, or emit any electromagnetic radiation . . .”

Do black holes reflect, or emit any electromagnetic radiation? Can we measure how much electromagnetic radiation they absorb? Do they contribute to the gravitational strength of their galaxies? If so, do we know how much?

[Pilgrim's Progress]

Joe Biden obviously has a problem identifying "dark matter" as well . . . seems that this is his black woman V.P. choice.
