Dark matter question?

Question

I watch particles flow toward and spin faster and faster into a decaying obit until it reaches the event horizon and goes down the drain.

Is dark matter like the water?

Answer 1

Apparently your analogy is correct.
Dark matter is all that nothingness between the Stars.
From our view point that is a lot of empty space. The truth of the matter is that it is not empty. We just can not see.

Answer 2

I entirely agree with elohimself. Dark matter is not anything special. It is just that, dark. It is like the Coal Sack nebula near Crux (the Southern Cross), - it is just a lot of dust and objects which do not reflect much light or are too small to emit their own. So they just sit there. Some sources suggest that dark matter is the predominant mass in the universe. Some say about 90% (see link below).
It interacts with normal matter, it is in fact, normal matter. It just cannot easily be seen from such vast distances as interstellar and intergalactic space.

Answer 3

Dark matter is the term for the supposed material that is like matter in that it has mass but has not been seen or accounted for by any form of equipment. They, being scientists, suggest that there is "dark matter" because they setup computer generated models of all the matter they can see and know is there and the galaxies literally fell apart. They then added in the "matter" necessary and found out it makes up around half of everything in the universe, so they labeled this missing, yet there matter "Dark matter". And it, as far as I can tell, is not like water in anyway.

Answer 4

Sorry, Dark Matter is completely different from water, it is completely different from everything you and I have seen until now.

The particles that made up dark matter should be new particles, exotic matter unknown until now, not equal to protons, neutrons and electrons.

It is a type of matter that exerts gravitational effects but it is invisible.

Answer 5

just regular matter would be like the water, according to common ideas of dark matter's behavior gravity doesn't affect it as much. Its thought that when a star is born dark matter expands outward and remains in a halo around the system. In your tub, dark matter might coagulate around the drain.. With a black hole its probably too far away to be attracted. The stuffs weird. It has mass, but doesn't interact with normal matter, or gravity like matter does so it wouldn't be caught up in the current of matter falling into the black hole.

Answer 6

Dark matter is not like water. It is not like gas, either. It is practically completely interaction free except for gravity. This means every particle will move basically in an independent orbit.

To those who think dark matter is "just"ordinary matter, please read e.g.

http://www.astro.princeton.edu/~dns/MAP/Bahcall/node2.html

for an explanation why it might not be. The argument is technical and non-conclusive. But it is non-trivial and not easily rejected by observations.

Answer 7

Because dark matter does not interact with normal matter(at least we don't think so), it cannot be affected by forces, even the tremendous gravitational force of a black hole. I am not an expert on this topic but I assume that dark matter could maybe disguise a black hole by encircling it, but not be consumed by it.

Answer 8

Here's the way I'm betting. I think that all the quasi-mystical, exotic quantum mechanical interpretations of "dark matter" are nonsense. I believe that "dark matter" is a proliferation of dust clouds, Oort/Kuiper type objects, roaming isolated planet-sized bodies, and brown dwarfs. Betcha.
