>Dark matter is called "dark" because it does not appear to interact with the electromagnetic field, which means it does not absorb, reflect, or emit electromagnetic radiation (like light) and is, therefore, difficult to detect

If it doesn't absorb electromagnetic waves then why isn't it called "Clear Matter"?

space isn't clear it's dark, but you're otherwise right probably. They call it dark because it's mostly not anywhere near stars and generally all spread about galaxies or something.

The entire idea of dark matter is completely pointless once you realize that gravity propagates slower than light.

That is the exact opposite of true. A vacuum doesn't absorb any light, making it perfectly clear, not dark.

Except it does. The entire idea of dark matter was made-up to explain why light appears to move faster than gravity when it doesn't with their model. Rather than admitting to being wrong, they had to "predict" a whole new type of matter to justify the results.

When the idea of "dark" matter was first proposed as an explanation for why the rotation of stars around galactic centers did not follow standard gravity models, astronomers had very little idea of what this hypothetical matter could or could not be. For example, some astronomers thought it could have been various hard to detect objects made of relatively normal matter - black holes, neutron stars, brown dwarfs, planets, etc, often collectively refered to as MACHOs (massive astrophysical compact halo object). Those obviously would not be clear matter in the slightest. Latter studies have largely ruled out MACHOs being more than a small portion of the "dark" matter required for galaxies to behave as they do. This is a big reason for the theory that dark matter is some sort of particle(s) sort of like neutrinos, but even more of a bitch to directly detect, is currently in favor.

And before anyone mentions it, yes, the idea that maybe gravity works differently at large scales as a solution for this issue, with dozens of proposed theories given serious consideration. However, everyone seen so far has had issues, especially with some more recent observations that are really hard to make work with modified gravity models. In particular, different galaxies with similar amounts of visible matter can have very different rotational curves for their stars. Dark matter theories can explain this as some galaxies having more or less dark matter due to large scale galactic interactions in the past, while I have not seen a modified gravity theory be able to handle this.

Dark Matter probably doesn't exist. The whole Big Bang theory is being increasingly questioned. Every time a hole in it is found (universe speeding up, missing mass, etc) they patch it and carry on. Occam's Razor just says they're going about it wrong

Not saying anyone has a better explanation, just that I doubt BBT is it

I said it before, and I'll say it again. Their model was wrong because they believe gravity propagates faster than light, when it's slower. Once you fix that by making gravity slower than light, dark matter becomes completely unnecessary.

That it doesn't seem to interact at all electromagnetically was not known from the start. Astronomy was much less developed when Zwicky coined the term. He only found that there seemed to be a large amount of mass that is literally dark, i.e. not shining like stars do. Everything else he could not know.

The standard theory is that gravity moves at the speed of light, not faster, and every serious attempt to measure the speed of gravity I can find place it very close to C, give or take measurement error. Do you have any studies that show a noticably slower speed for gravity?

Also, how does your proposal that gravity is moving slower than light explain the so called "dark matter deficient" galaxies, a small number of dwarf galaxies that do not have galactic rotational curve issue, while other visually similar galaxies do?

What is more likely? Invisible substances that exclusively interact with gravity permeate the universe or the model is just innacurate?

No, but if you calculate as being slower then the rotation of starts around galactic centers works without dark matter/energy. It even still works with dwarf galaxies.

Modern physics is duct tape-code. Nobody can admit that a model is wrong, they can only add shit to what's already there.

Honestly, the former seems more likely, given the circumstantial evidence. And there have been several times in the past where assuming the model is correct, but some then invisible stuff is throwing things off has yielded useful results in the past, like the discovery of neutrinos.

So basically if we ignore all the experimental & observational evidence placing the speed of gravity at very close to C, then your math works out. Color me skeptical. And which dwarf galaxies does the math work out for - the majority that have the rotational curve issue, or the small number that don't have the rotational curve issue?

You are already ignoring observations. Your model doesn't explain large scale gravity. Your math is wrong, the universe isn't. You can't just add a "+C" to your model like you are doing sophomore level calculus and expect everyone to buy it.

>>14348122
Sometimes adding a +C is the correct answer though. Look at how neutrinos were discovered - physicist in the 1920s noticed that beta decay didn't match their model of how momentum is conserved, so Pauli said lets add a +N particle that is invisible and super hard to detect to explain it. Several decades later he was proven right.

Likewise, if every observation & experiment we do on Earth places the speed of gravity at close to C (for example, gravity waves being detected from colliding neutron stars at LIGO compared with Fermi detecting the gamma ray burst at almost exactly the same time) you can't just ignore that without a damn good reason. Your model needs to explain why we see the speed of gravity being extremely close to C, even over the intergalactic distances we can detect gamma ray burst & gravity waves due to neutron star collisions from.

This is you:

"Sound doesn't have a medium cuz we cannot see any, but we did notice that trees sway due to some unknown force, let's call it dark-tree-movement. And we noticed that dark-tree-movement is none interactive with sound, how odd. But we know that sound has no medium otherwise we'd be able to see it. Stange. Whatever could explain this phenominon????"

Do you have any fucking idea how retarded you are compared to us who have actually figured all this shit out? We are, no joke, aren't 100 to 1000 years more advanced in understand than you fucking clowns.

I honestly don't think you all will ever catch up.

We cannot even explain shit to you because of how fucking brainwashed you faggots are. You reject the most basic fucking evidence and logic.
