Star Talk: Dark Matter and Dark Energy

The whole idea behind Dark Matter is because we cannot leave space blank and get the Universe and galaxies to make sense in computer/mathematical calculation and models. "Dark Matter and energy are not referred to as dark because of color, it is because knowledge is dark....or better termed unavailable. Yet a name is required to communicate the concept. I prefer the term unknown gravity source but that is a bit bulky.

 

Again, that's just the arithmetic of it.
How about the arithmetic of an elephant's effect on its' surrounding to define, an elephant.
Proof of an elephant's existence when no elephant is known before.
Or we just term Dark Matter as 21st Century Ether.
Ether rediscovered. https://en.wikipedia.org/wiki/Aether_theories Why not?

That is pure hubris of humanity to imagine the universe has to fit into our calculations. That is the first problem. Just being empty space is not only possible, but more and more likely probable given the alternatives and the sheer volume of insanity needed to swallow it whole...

 

Dark matter has been suggested because our current theories predict a constant rate of expansion of the universe. That's not what the data shows. So dark matters 'fixes' the problem. There are 3 possibilities; dark matter exists, the theory is wrong, or the data has been misinterpreted. No one knows which is correct atm.

 

It would seem your understanding of how scientific pursuit happens is askew. We do not try to make the universe fit into our calculations, instead we create calculations to understand the Universe. Any Hubris in this is coming from you pretending you have some idea what you are talking about.

 

Go reread what you wrote. That is what I responded to. Talk about having no clue what you are talking about...

 

You are confusing dark matter with dark energy.

Inspired your reply?

 

Dark matter is called dark because it emits no light. It is not a metaphor.

 

Dark matter has been inferred due to gravitational lensing and effects at the galactic scale, not because they need it to make the models work. In fact dark energy - the accelerating rate of expansion - is likely more significant to cosmological models in the sense of fundamentals, than dark matter. Dark energy may represent an unrecognized, fundamental force.

It actually IS in scientific circles. Though it obviously does not interact with photons or traditional matter forms it is so little understood that cosmologists refer to it as dark due to the lack of knowledge...though the lack of light makes the term additionally useful. The gravitational actions are an interesting aspect and many consider the possibility of dimentional bleed likely....myself included.

 

That's the whole point about this 'deep space' stuff - it's all based on theory, the reason being that there's no way it can be proved: it's merely the product of various persons' imaginations, and what does that amount to? In my book, if a total stranger tells me something without at least a modicum of tangible evidence to back it up, then it isn't of the slightest interest to me; and I'll never understand why it is of interest to others.

 

Whoops, my bad.

 

Well let's face it - does it matter? See what I did there? They probably can't believe so many of you actually believe this ****. I sure can't!

 

Of course it is arithmetic or physics. You can try to spin this in this ridiculous way but it's silly.

 

Not to a thinking person who avoids popular Science for the Real Thing.

The Higgs Boson team did not have one doubter on the team I betchya
With a lot of faith based scientist, how could they not "find it"

A top Neutrino professor was at my University back in the late sixties.
Back then a Neutrino was a particle without mass or charge. Today it isn't.

I use to argue with a younger anthropologist that
Neanderthal was in the Euro genome before it was popular.
Evidence in skull structures of modern Europeans. Before 23AndMe.
And we went at it for decades until "Moi" was proven correct.

Over my years of Science and Medical Science I have witnessed more
faith based followers. Sanja Gupta, M.D. regarding , another example.
He came around when the evidence of appropriate Schedule 1 classification just did not really stand up to "science". It never did. Yet he pimped the Schedule 1 classification for decades. If only he had read his New England Journal of Medicine he might have come around sooner.

And the heretic, the Non Believer of the current science gospel doesn't get grants.
It is that simple.

So yes I reject Dark Matter as nothing more than an equation filler.
And the ridiculous ones are those who preach the Gospel of Science.

 

You're entitled to your opinion over the facts but not the facts themselves. You must have an explanation as to why galaxies don't fly apart. Otherwise you're just spouting nonsense.

 

I see you can copy and paste, too bad you can't even comprehend what you yourself wrote when it comes under criticism.

 

Actually, those are my own words and my understanding of this subject is about as comprehensive as the layperson can expect. Unless you are in the field of cosmology or physics I highly suspect my knowledge base exceeds your own, Please offer the critique of my commentary you claim me incapable of countering rather than pointless attempts at insult through weak diatribe. I would love to see your own educated opinions on the Dark Matter/Energy hypothesis as you obviously find my own to be flawed.

 

No I don't.
Just to say it is scientifically neither ether nor dark matter.
Well maybe ether is clumpier than we originally thought

 

You still don't even begin to understand what I said the first time and you prove it over and over again with your lack of understanding of even your own words.

I don't require a special theory as to what is or isn't there. We know well enough that space is not empty, there is radiation from various sources, magnetic fields, drifting solid matter (asteroids, comets, meteors, etc..) there is no need to create 'dark' matter just so human constructs like theories will work on the human construct computers to 'prove' the truths of the universe. That is the height of lunacy...

 

Please then, explain the gravitation anomalies that allow a Galaxy to form and stay that way. Is it all that asteroid interaction and radiation?

 

Which anomalies are you speaking of? Clearly the most central aspect that shape galaxies would be the sun in which planets and other bodies orbit. Granted its possible for a system to have more than one sun which would really change all the dynamics and we are in no position to even begin to guess the effects that would have. There are lots of things we don't understand, but theories like 'dark' matter aren't really helpful, because they aren't specific enough, it comes off as a sorry excuse to cover true ignorance...

 

If you're going to poopooh a theory then you need a better one than you're espousing which is nothing. I'll concede dark matter is a nebulous subject with no real discrete answer but it does address the issue there is some substance exerting its gravitational influence. It is an explanation as to why galaxies act as they do. The fact we don't know exactly what it is particle wise doesn't invalidate it is there doing its thing.

 

I asked about Galactic (Galaxy wide) Gravity not Solar system dynamics. Of course our star plays the lead role in our local orbits but our sun is one of Hundreds of billion that make up our Galaxy. These Galaxies simply do not contain the mass required to stay in our Galactic form, even with a super massive black hole in the center.
I want to know your hypothesis as to what allows this to happen throughout the Universe for the hundreds of Trillion of Galaxies?
