@athousandyoung saidNon baryonic dark matter is a theory, but baryonic dark matter is not. Although Fritz Zwicky was the first to suggest dark matter he did not suggest non baryonic dark matter, so that video is based on a myth.....unless she is talking about normal baryonic dark matter.

43 minutes long, be warned
Who was the first person to come up with non baryonic dark matter theory?
In fact, when it was discovered that neutrinos have a tiny amount of mass, that would be an example of nonbaryonic dark matter. "Dark" because up until the turn of the century we couldn't "see" the matter in neutrinos. There are a lot of neutrinos in the universe, so their mass does add up to something, but nothing close to enough to explain away all dark matter.

@Metal-Brain
Maybe you would find out if you actually watched the video.
@sonhouse saidI did. How do think I knew they mentioned Fritz Zwicky?
@Metal-Brain
Why don't you watch the video, are you afraid you might learn something?
Zwicky never suggested the dark matter was non baryonic matter. People just falsely assume that he did because he called it dark matter, but he was talking about baryonic matter.
Who was the first to suggest the idea of non baryonic matter? Contrary to popular myth it was not Zwicky.
@Metal-Brain
What difference does it make just what the stuff is? It is real, it is the reason galaxies can exist in the first place, it makes up the majority of mass in the universe, far more than normal baryonic stuff we are made of.
Do deny those facts? The facts are this: Whatever the stuff is it does not react with our matter, it could be a mass of neutrinos for all we know or primordial black holes, it doesn't make any difference to the affects it produces which is to be needed to provide the gravity to get regular matter to clump together to make stars and galaxies or our universe would be a vastly different place.

Because you don't know what is real. You don't know non baryonic matter is real because it is purely theoretical. Who came up with the theory of non baryonic matter and why is it so hard to find out? Doesn't anybody want to take credit for it?
@soothfast saidHe doesn't know what the stuff is but it is real......whatever it is.
There needs to be a couples counseling forum here.
😆
@Metal-Brain
So you think anyone else on Earth knows what the stuff is? we know it is there and what it does, that is enough for now.
Exactly what do you think would be gained if we knew exactly what the stuff was anyway?
It sounds like you again just wanting to show how incredibly smart you are compared to us non communist stooges.
Tell me what difference would it make in our lives if we knew exactly what that stuff is? You think maybe we could manufacture some of it and us it on a space drive or some such? make a new power source?
Are you making a case that there is no such thing as dark matter? What?
@Metal-Brain
Whether MOND is true or no, it won't effect the evidence we have for dark matter.
Are you saying you think dark matter is not real, no such thing? Presumably because you somehow without proof that MOND is responsible for what evidence there is?
@sonhouse
"Whether MOND is true or no, it won't effect the evidence we have for dark matter."
That is the most dishonest statement you have made in a while. If MoND is true the amount of dark matter needed to explain observation becomes less. That is a big deal since you have no evidence non baryonic matter even exists. You have no more evidence than observation which means you have no more evidence for non baryonic matter than I have evidence of planet X.
In fact, I have more evidence of planet X than you have for non baryonic matter. You don't have MoND as an alternative to explain why the orbits of the outer planets are being affected by something that tugs on them.
Do you accept planet X exists? We cannot see that either. Is it dark matter or regular matter that is dark?
