Dark matter has never been proven to exist. Claiming that something is composed of a substance that hasn't even been proven yet to exist is irresponsible.

@@christinebethencourt6197 Before even starting to watch this, I can tell you one very useful thing to know: the vast majority of the stuff going on in the universe isn't light in the visible spectrum. Our eyes can only see a teeny tiny bit of electromagnetic radiation (red to violet, basically) but we can use instruments to detect the rest of it (below red is infrared, microwaves, and radio waves, and then above violet you get ultraviolet, x-rays, and gamma rays). And then there are ways of detecting things that don't require directly measuring their electromagnetic radiation/light at all. For example, the evidence we have for dark matter is that the edges of the galaxy rotate as if there was more matter there than we can "see." There must be something there that has gravity but isn't putting out any electromagnetic radiation: that's why they call it dark matter.
This is a nicely done presentation. At first, I feared that the presentation was drifting toward the realm of mis (dis?) information until the very end of the presentation.

Everything or at least most things, are made of energy. But, not all energies emit light during there existence. There are seemingly endless ways of existing that we aren't aware of yet.

Well made video. There is an elephant in the room explanation for those abnormally high star rotation rates. It is the original, forgotten explanation for why we cannot see light from the galactic center. Most people don't know that Einstein said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote "the essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of GR predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation (sometimes called gamma or y). Mass that is dilated is smeared through spacetime relative to an outside observer. This is illustrated in a common 2 axis relativity graph with velocity (from stationary to the speed of light) on the horizontal line and dilation/gamma/y on the vertical. The graph shows the squared nature of the phenomenon, dilation increases at an exponential rate the closer you get to the speed of light. Wherever you have an astronomical quantity of mass, dilation will occur because high mass means high momentum. There is no place in the universe where mass is more concentrated than at the center of a galaxy. General relativity does not predict singularities when you factor in dilation. Einstein is known to have repeatedly spoken about this. Nobody believed in black holes when he was alive for this reason. In the "Annals of Mathematics" Einstein spoke about dilation occurring in regions that would less mass than that which would exist at the center of common spiral galaxies. Therefore, it is safe to say that according to Einstein's math the mass at the center of our own galaxy must be dilated. In other words that mass is all around us. You could use the same math to calculate the surface rotation of the sun if you doubled it's mass. The reason why we cannot see light from the galactic center is because there is no valid XYZ coordinate that we can attribute to it, you can't point your finger at something that is smeared through spacetime. According to Einstein's math, galaxies with very, very low mass will show no signs of dark matter because they do not have enough mass at the center to achieve relativistic velocities, therefore they are not infused with dilated mass. This has been confirmed by galaxy NGC 1052-DF2. A simple way to confirm this would be to calculate the star rotation rates of a large number of galaxies. This would show that all the high mass galaxies would have star rotation rates that defy the known laws of physics and all the low mass galaxies (some galaxies can appear to be low mass but can have high mass at the center) would have predictable star rotation rates.
@@asai1244 I know of one study from the 90's that said stars near the galactic center where approaching the speed of light. There is no way to know this through observation however. The interference alone, dilation alone or gravitational lensing alone would make that virtually impossible. The idea that there is some way to take a picture of the galactic center is absurd. As per relativity, an observer would have to exist at or near it's momentum.
The shape of a galaxy is common in nature. From atoms to our solar system, the overwhelming majority of the mass is in the center. Where there is mass there is energy. The night sky should be lit up from the galactic center but it isn't. The modern explanation for this is because gravitational forces there are so strong that not even light can escape. Einstein's answer would be because the mass there is dilated relative to an Earthbound observer. This was the accepted explanation until television and movies popularized black holes in the 1960's. Belief in them gradually became mainstream despite the fact that Einstein said that they cannot exist and there was no evidence.
So, say goodbye to MOND? Wouldn't that be nice. Not because a new theory (hypothesis actually) bites the dust, but because we finally get some clarity!
dark matter is observed indirectly. Like throwing a ball over one wall to have it bounce off a wall behind it. You know there is something there. Thats all we know. There is something there. Is it a new material, existing matter, or a problem with our current theories?
we should call it an XYZ "ickzees" Galaxy, cause in the yugioh ZeXal anime, Number monster when summoned form a dark purple galaxy like shape before appearing, while regular XYZ monsters appear from a galaxy of light.
I am honestly doubtful, if only because the video lacks some key details like the sigma level of certainty. Dark matter is in my eyes the same as aliens, it isn't until it is.
The size of the universe is beyond comprehension. Astronomers have stated there are more stars in the universe than grains of sand on all the beaches on earth. Wrap your heads around that!
Hey ive got a crazy question to any academic in the house. What if all amateur astromers in one hemisphere all pointed their telescope to the exact same spot in the sky in a high exposer shot. Is it possible to take all the images and combine them for a super high resolution image? Lets say one of the proxima exos. Would combining the image of millions of amateur telescopes give the resolution necessary to see it, or is this a dumb idea? Maybe add all the professional telescopes in that hemisphere and all space telescopes too. Everyone, looking at the same spot and combining the image. Maybe like the electric sheep program, use everyones PCs to process the data. Would this work or am i nuts?
The first time science detects dark matter and/or energy, will be a revolutionary new era of astrophysics and astronomy that will be like when Hubble discovered the expansion of the universe. I have a healthy understanding of the mortality of humanity, but I have to admit that I would love to be able to witness how we advance our understanding of the universe in many future generations. I would like to upload my consciousness into a digital system where I could be able to see what we learn from another century or two of scientific advancement…
If a particle can have wave attributes than a wave can have particle(mass) attributes as well. It could be very well possible that the unknown matter or mass is some form of very dense gravity that is holding itself together as a type of object with mass
It would indeed be fascinating. The problem is that they then say that some light is indeed being emitted but at a very low percentage which might indicate a baby galaxy.
In the case that the AQUAL theory discussed in the video from 2 weeks ago is correct and dark matter really doesn't exist, I wonder what would account for the baryonic to dynamic mass ratio of dark galaxies.
What we “know about" what we observe are really no more than mathematic models.Ptolemy’s geocentric model of the Universe was based on what I suppose was thousands of years of direct observatIon of the skies prior to his time.
I know astronomers invert the plates to reverse the light and dark to clarify the field of stars they study. So the lighter colour is dark and the dark is light. The plates you showing wouldn't be sans lumination, just the opposite - so what am I missing here? Wouldn't a dark galaxy also be light in colour on the plates? Or are you showing us is just a bizarre example?
From this epi Conclusion, In between Andromeda and milky way galaxy . There are many dark matter galaxies in between Andromeda galaxy and milky way galaxy. Like this. Many dwarf galaxies can have 80 dark matter and 20 per visible matter. Means dwarf galaxy can have more matter than we thinks
Speaking on dark matter as if it's been proven...This is the first and last video from this channel I'm watching. I can't take channels like this seriously when they just make shit up.
Abiogenesis has not been observed to occur in nature. Neither can it be forced to happen in a lab. So there is no scientific basis to assume that it is happening all over the universe.
Dark matter? Or maybe a Kardashev 3 Civilization or greater?... Dark matter halos? A civilization would expand on the outer areas of the galaxy first, then advance towards the core where higher technology is required to settle in. So a dark matter halo would be an expected structure to see.
Baryonic matter comprises only 4.8% of the entire universe, and yet stands as the material foundation for everything we have ever known, including ourselves. By comparison, Dark matter comprises 23% of the universe, and the only thing we know about it is that it gravitationally influences Baryonic matter. All according to current cosmological theory, of course. But, with those ratios in mind, I think it's fairly safe to conclude that our Baryonic matter is really Dark Matter to all the lifeforms inhabiting a material universe approximately 5x larger than our puny celestial playground. Don't you just love science!
Рік тому
Or maybe it is a civilization that consumes the total energy of the galaxy for its own needs?
Once I heard dark matter I did not waste another minute. Dark matter and dark energy are impossible to see or measure so they can't be disputed. Pure unicorn farts presented as science.

You could use the same math to calculate the surface rotation of the sun if you doubled it's mass.
The reason why we cannot see light from the galactic center is because there is no valid XYZ coordinate that we can attribute to it, you can't point your finger at something that is smeared through spacetime.
According to Einstein's math, galaxies with very, very low mass will show no signs of dark matter because they do not have enough mass at the center to achieve relativistic velocities, therefore they are not infused with dilated mass. This has been confirmed by galaxy NGC 1052-DF2.
A simple way to confirm this would be to calculate the star rotation rates of a large number of galaxies. This would show that all the high mass galaxies would have star rotation rates that defy the known laws of physics and all the low mass galaxies (some galaxies can appear to be low mass but can have high mass at the center) would have predictable star rotation rates.
Ur smart this is probably the longest comment in this video
Aren't we able to see stars orbiting at relativistic velocities around the galactic center of the Milky Way?
@@asai1244 I know of one study from the 90's that said stars near the galactic center where approaching the speed of light. There is no way to know this through observation however. The interference alone, dilation alone or gravitational lensing alone would make that virtually impossible.
The idea that there is some way to take a picture of the galactic center is absurd. As per relativity, an observer would have to exist at or near it's momentum.
The shape of a galaxy is common in nature. From atoms to our solar system, the overwhelming majority of the mass is in the center. Where there is mass there is energy. The night sky should be lit up from the galactic center but it isn't.
The modern explanation for this is because gravitational forces there are so strong that not even light can escape. Einstein's answer would be because the mass there is dilated relative to an Earthbound observer.
This was the accepted explanation until television and movies popularized black holes in the 1960's. Belief in them gradually became mainstream despite the fact that Einstein said that they cannot exist and there was no evidence.
@@shawns0762 thanks, what about this though? ua-cam.com/video/duoHtJpo4GY/v-deo.html Just curious as to your thoughts on this...
Ultra-faint galaxies are stellar nurseries. They're not old. The perpetual absence of large stars accounts for their low metallicity.
So, say goodbye to MOND? Wouldn't that be nice. Not because a new theory (hypothesis actually) bites the dust, but because we finally get some clarity!
MATH: Your numbers are wrong.
SCIENTISTS: "70% of the universe must be invisible."
Would love to explore that location
A dark galaxy with dark starts, that would be cool.
What tf are dark starts?
dark matter is observed indirectly. Like throwing a ball over one wall to have it bounce off a wall behind it. You know there is something there. Thats all we know. There is something there. Is it a new material, existing matter, or a problem with our current theories?
Really I like this video so so much its so interestyng
How the hell can anyone detect a whole galaxy with no sliver of light? Not even infrared???
we should call it an XYZ "ickzees" Galaxy, cause in the yugioh ZeXal anime, Number monster when summoned form a dark purple galaxy like shape before appearing, while regular XYZ monsters appear from a galaxy of light.
I am honestly doubtful, if only because the video lacks some key details like the sigma level of certainty. Dark matter is in my eyes the same as aliens, it isn't until it is.
Greetings Travelers,
It is so nice to see you on this timeline, in this dimension.
I hope we can meet again before the end
Safe Travels
“ I feel it coming ……” (Daft Punk)……🧑🚀safe travels you too 🙋♀️
We have
The size of the universe is beyond comprehension. Astronomers have stated there are more stars in the universe than grains of sand on all the beaches on earth. Wrap your heads around that!
To what depth are those sand-grains being counted?
@@Radrook353 If I only knew
Hey ive got a crazy question to any academic in the house. What if all amateur astromers in one hemisphere all pointed their telescope to the exact same spot in the sky in a high exposer shot. Is it possible to take all the images and combine them for a super high resolution image? Lets say one of the proxima exos. Would combining the image of millions of amateur telescopes give the resolution necessary to see it, or is this a dumb idea? Maybe add all the professional telescopes in that hemisphere and all space telescopes too. Everyone, looking at the same spot and combining the image. Maybe like the electric sheep program, use everyones PCs to process the data. Would this work or am i nuts?
To answer your final question with a bit of humor, can't it be both?
The first time science detects dark matter and/or energy, will be a revolutionary new era of astrophysics and astronomy that will be like when Hubble discovered the expansion of the universe. I have a healthy understanding of the mortality of humanity, but I have to admit that I would love to be able to witness how we advance our understanding of the universe in many future generations. I would like to upload my consciousness into a digital system where I could be able to see what we learn from another century or two of scientific advancement…
If a particle can have wave attributes than a wave can have particle(mass) attributes as well. It could be very well possible that the unknown matter or mass is some form of very dense gravity that is holding itself together as a type of object with mass
It’s probably just emitting radiation in different wavelengths just not that of visible light.
Yes, radio waves such as the hydrogen 21 - centimeter line. But stars give off visible light ... and so it's the stars that are missing.
A galaxy with no light emitted, Looks like a dream but it came true🌌
It would indeed be fascinating. The problem is that they then say that some light is indeed being emitted but at a very low percentage which might indicate a baby galaxy.
In the case that the AQUAL theory discussed in the video from 2 weeks ago is correct and dark matter really doesn't exist, I wonder what would account for the baryonic to dynamic mass ratio of dark galaxies.
What we “know about" what we observe are really no more than mathematic models.Ptolemy’s geocentric model of the Universe was based on what I suppose was thousands of years of direct observatIon of the skies prior to his time.
I know astronomers invert the plates to reverse the light and dark to clarify the field of stars they study. So the lighter colour is dark and the dark is light. The plates you showing wouldn't be sans lumination, just the opposite - so what am I missing here? Wouldn't a dark galaxy also be light in colour on the plates? Or are you showing us is just a bizarre example?
From this epi
Conclusion,
In between Andromeda and milky way galaxy . There are many dark matter galaxies in between Andromeda galaxy and milky way galaxy. Like this.
Many dwarf galaxies can have 80 dark matter and 20 per visible matter.
Means dwarf galaxy can have more matter than we thinks
👍
at 5:41 narration mistake
Could it be so far away then That only the gamma rays coming through as radio waves from red shift
I thought we may have encountered a Type-III Civilization. Would have been really scary.
Just a peak into a vast universe ❤
Great News !
So how did they see it then?
"Astronomers have discovered a galaxy that emits no light, except for a small fraction of stars"
Well then, the galaxy DOES EMIT LIGHT, YOU TOOL!
Speaking on dark matter as if it's been proven...This is the first and last video from this channel I'm watching. I can't take channels like this seriously when they just make shit up.
Looks similar to my dream Galaxy
finally and most importanly, likes that words 😁
Great video thanks, The more we see, the more we understand, that we DON’T understand👨🏿⚕️🤓keep searching🔭👏🏿👏🏿🦠💉😷
The devs left it in as an easter egg
"What does dark matter?" LOL
Why does this channel feel like I'm watching The Onion?
So many rocks there
I have a galaxy
of my own that quit emitting light because the screen broke
First of all... dark matter is just a theory.
Hypothesis.
Incredible....
Dark Galaxy sounds like Metroid Prime Game
Effectively a skeleton without the muscles, organs, etc? Interesting! Hopefully it solves the dark matter problem
This video is not suited for watching on HDR screen late at night.
Universe is amazing, mysterious, unbelievable, cool, fascinating, exciting, full of secrets, marvellous,
Just like
OMG
If this is factual, if one of these plantes or life forms this galaxy was in front of us would we even see it?
Abiogenesis has not been observed to occur in nature. Neither can it be forced to happen in a lab. So there is no scientific basis to assume that it is happening all over the universe.
You literally say in the video they are made up of stars that DO emit light.
Making your "Emit No Light" claim in the title completely untrue.
Dark matter? Or maybe a Kardashev 3 Civilization or greater?... Dark matter halos? A civilization would expand on the outer areas of the galaxy first, then advance towards the core where higher technology is required to settle in. So a dark matter halo would be an expected structure to see.
Wonder what happens if you and melody sheep collaborated
Baryonic matter comprises only 4.8% of the entire universe, and yet stands as the material foundation for everything we have ever known, including ourselves. By comparison, Dark matter comprises 23% of the universe, and the only thing we know about it is that it gravitationally influences Baryonic matter. All according to current cosmological theory, of course. But, with those ratios in mind, I think it's fairly safe to conclude that our Baryonic matter is really Dark Matter to all the lifeforms inhabiting a material universe approximately 5x larger than our puny celestial playground. Don't you just love science!
Or maybe it is a civilization that consumes the total energy of the galaxy for its own needs?
that means dark matter interacts with itself, probably through dark sectors of electromagnetism and nuclear force
They are probably all over, we just cannot see them easily
This galaxy could be gas dense and gas rich which traps light.
We cannot say it’s dark matter because we cannot observe dark matter yet.. only it’s effect.. or it’s conforming to the predictions mentioned
Exactly! Something is causing the effects. We do not have any basis to be calling it matter. We are assuming that it is matter.
A Maybe you found an old galaxy whose energy all burned out. Nothing left but cold rocks. There's still some heat at it's center.
Scientists have discovered a "galaxy" made up of 90% non-existent fairy dust. They'd named it the horse-shit nebular. LOL.
Ah yes, a type 3 civilization
How was it found the ?
Observations don't match the predictions? No, the predictions can't be wrong...
A real image of it would have been handy.
Once I heard dark matter I did not waste another minute. Dark matter and dark energy are impossible to see or measure so they can't be disputed. Pure unicorn farts presented as science.
THE UNIVERSE IS FULL OF FUN.🎉❤🎉
Wait how can you discover a galaxy that doesn’t emit light
since its a dark galaxy they named it "Ghettosha"
