Dark matter and Dark energy

[Belz...]

In reality much in science has been vetted through the scientific method.

Every theory starts with observation which leads to hypothesis. The hypothesis is always made up, and is sometimes confirmed. Your statement was a truism.

Dark matter has not, it is just an idea without evidence.

And what about the ton of evidence you've so far ignored ?

 

[~enigma~]

you explain your point of view.

Why didn't you answer a direct question? Are you afraid to admit that your view is not falsafiable? In other words it isn't based on science it is based on faith. You as well as BAC are religious woo.

The neon in a lamp is in a plasma state. It's not a matter of proving a claim, it simply meets the requirements of the definition of plasma.

The original question was isn't neon a gas and it was asked when robinson made the idiotic statement that gases do not conductelectricity or emit light. Unless neon (and for that matter Argon) isn't a gas then hi statement was totally stupid and meant to do nothing but try to be "cocky."

The question I asked BAC was about his EU fooishness. What claim did you think i was referring to?

You were not replying to BAC in that post, you were replying to iantresman. And you certainly seemed to be denying that the neon in a fluorescent light is a plasma:

Correct. It becomes a weakly ionized plasma which includes a mixture of neon gas and ionized gas... which is called a plasma.

And i repeat you are a fool. That is the exact same argument by bible thumpers that although it says that it really means something else. You demonstrate a MAJOR ignorance of chemistry.

I think Langmuir demonstrated beyond reasonable doubt that when you ionize a gas, it becomes a plasma. I'm not sure how you would disprove this.

The question is not about gas. It is about your ridiculous EU stupidity.

Do not attack other posters.

And it said I will ask you the same question I asked BAC. When did I ask BAC about neon being a plasma? Why are you still telling me what I meant even though I explained it?

• You wrote: "So the neon gas becomes not a gas?" (that looks like a question)
• I replied, "Correct. It becomes a weakly ionized plasma" (which looks to me, like a direct answer to your question.)
• You retorted, "And i repeat you are a fool. That is the exact same argument by bible thumpers" (which is not the best argument I've seen)
• And I replied again with three citations. (more direct answers)
• You replied: "Why didn't you answer a direct question?"

I think I have shown that I have (a) answered your questions directly (b) with citations, and although you have called me a fool twice now, I have respectfully asked for your view on why you disagree, and, would be interested to know why this makes me a fool.

You have answered nothing. You are able to read aren't you? I explained both to you and Yllanes that you misunderstood what I was asking but you still seem to be unwilling to answer. That is enough to tell me that you don't want to answer since doing so will prove that your EU crock is nothing but a faith based piece of tripe.

 

[Yllanes]

I'm not telling you what you meant, I'm telling you what I understood, because you asked me to do so:

The question I asked BAC was about his EU fooishness. What claim did you think i was referring to?

Why not?

Have you not been paying any attention? I've made this point repeatedly now. Because if it only interacts via gravity, it can't lose energy the way ordinary matter does. In order to stick together, ordinary matter has to be able to lose energy - otherwise it'll just fly apart after being attracted close together. If there's no mechanism to lose energy, it won't stick together. Your grasp of basic mechanics is evidently as lacking as your grasp of elementary electromagnetism.

 

[Dancing David]

I said something about it. If "dark matter" is suspected because of it's gravity, then it attracts and is attracted to matter. (Or bends spacetime if you want to go all Einstein). Either way, things that have gravity move towards each other, and combine with each other.

So DM would do the same. What happens when it comes into contact with matter? Stars? Does it act like matter? Form structures? Rain down on planets?

How could it stay away from things it is gravitationally attracting? Or the other way around?

Well, it could be something like neutrinos which have mass but interact very very very very infrequently with 'ordinary' energy/matter. We are awash in this absolutely huge sea of neutrinos, all the time. We just don't interact with them except very rarely.

If the 'dark energy' is related to the 'vacum' energy, then it is even stranger stuff.

 

[Ziggurat]

Never to return? Then is it electromagnetic force that keeps comets coming back?

Who said anything about never returning? The issue isn't never returning, the issue is sticking. We've seen one comet stick to another body. Do you know what force is responsible for the fact that the comit stuck, and did not simply pass through that body? Hint: it wasn't gravity.

 

[robinson]

Get a grip man!

Dark matter is not some weird magical fairy dust. It's probably just regular matter. It just doesn't shine.

Heck, it might just be gigantic flocks of planet-sized chicken flying about.

Probably, possibly, absolutely, presumably, perchance, alledgedly, statistically, maybe, apparently, most likely, presumably, plausibly.

Does that answer your questions ?

That isn't what other people say.

Followed by a link that says exactly what I said. How quaint.

Your answers sound like woo woo.

 

[Dancing David]

And the fact that life is here and we have no explanation as to how it got here suggests God.

See, they are both making up concepts to explain the unknown.

No, I think it suggests much more interesting things.

The Cosmic Office Party had a Fling and we are in the Dupster Out back, then there are the Great Crumbsnatcher and Cosmic Coyote scenarios as well.

Some questions have no answers, which is just grand. We notice gravitational attraction that is not explained by current theories, so hypothesis and revision take place. Just like pi-mesons, neutrinos and Yukawa particles, there were many candidates like 'the ether' that did not make the cut from hypothesis to theory that predicts the behaviors of the universe.

 

[Dancing David]

Why not? Why can't it form a dark matter dark hole that creates such incredible gravity that it bends space just like a black hole made from ordinary matter? And don't try to squirm out of this question by telling me that black holes are a form of dark matter. That's not answering my question.

It might make black holes. But given that it might not interact with EM (if it exists) then it would not clump up like some oethr forms of matter and energy.

Do neutrinos make black holes?

 

[robinson]

The gravitational attraction IS explained by some theories. Those theories contradict other theories, and while I find it hilarious to see a theoretical substance (Dark Matter) subjected to the sort of skepticism that is usually reserved for God or Ghosts, the attacks on the Theories that do explain the rotation of Galaxies are no less, and all just reek of skepticism.

 

[Belz...]

Get a grip man!

Get a grip what ? What, exactly, requires me to get a grip ? Or are you abandoning your line of reasoning ?

Your link said this:

"Some people speculate, based on the evidence, including galaxy rotation curves, gravitational lensing, structure formation, and the fraction of baryons in clusters and the cluster abundance combined with independent evidence for the baryon density, indicate that 80-90% of the mass in the universe does not interact with the electromagnetic force. This "dark matter" is evident through its gravitational effect. Several categories of dark matter have been postulated."

How does that make dark matter "weird" ? Neutrinos don't interact with the EM force. Are they weird ?

 

[Belz...]

Those theories contradict other theories, and while I find it hilarious to see a theoretical substance (Dark Matter) subjected to the sort of skepticism that is usually reserved for God or Ghosts...

Robinson, you again don't seem to know much about the subject matter.

Pray tell, what other theory explains the observations ?

What other theory has been confirmed ?

And now you can compare with God or ghosts.

I've clearly been discussing neon gas and plasma. Why have you suddenly switched to mentioning the Electric Universe, when I have said nothing about it?

If you think that I misunderstood what you are asking, then the onus is on you to try and explain you point better. Calling people fools is not constructive.

You intend to answer or are you going to keep making excuses not to?
