Dark Matter

[Rev. Rex]

What do you think it is? Measurements have shown that all of the dust, stars, rocks, and hydrogen in our own galaxy wouldn't hold it together for even two rotations, as fast as everything is spinning, unless it was about 90 times more massive than we are able to detect. So what do you think that the "missing" 90% of matter is?

This has puzzled me for some time and I often wonder if it actually even exists. I don't know that much about the theoretical side of it but the notion that the universe is expanding at an ever increasing rate is also a bit of a strange one when you'd expect it to be slowing down rather than speeding up.
When taking into account all the strange aspects of the quantum world and how much the science community still doesn't understand, I wouldn't be surprised if something more fundamental has been overlooked. If the sums says that there's a missing 90%, either there's a missing 90% or the sums are wrong!

Interesting post. The mathematics are really pretty simple. We don't know what the mass of the Milky Way is, but we do know the speed at which it is revolving around the center. We can also measure the average gravitational pull. So if we measure the mass of what we can see and extrapolate; stars, dwarfs, planets, asteroids, gasses, dust, etc; we can then say what SHOULD happen to such a collection of objects moving at the speed it is moving. From this, two things glare out. First, at the speed that the galaxy is revolving, just from KNOWN mass, it should fly apart, just like putting a bunch of beads on a string, but not knotting the end, and twirling the string. Second, and this is even more interesting, is that from all objects and observational data we have, when a structure, even a loose one, rotates, the center moves faster than the edge, because of the greater distance from the center. We can even see this in a phonograph record. But in the Milky Way, that isn't what happens. From the center moving outward, the rotational speed slows down for about 2,000 light years, then it does a curious thing...the rotational speed levels out. The result is that an object about 50,000 ly from the center of the galaxy is rotating around the center at roughly the same speed that an object that is 100,000 ly from the center. The only way to explain this simply (and the universe generally operates by the simplest possible laws), is that there must be an enormous amount of mass that we don't know about, and it must reach far beyond what we can see as the edge of the Milky Way. In fact, it is sort of the same reasoning that led to astronomers knowing about the Oort cloud that exists far beyond the orbit of Pluto, and which we've now detected observationally.

Dark Matter is the most amazing thing. I am a student at University Of Metaphysical Sciences and they talk about it briefly in one of their courses, but I have also learned about it at my community college in a cosmos class... it is amazing stuff! At University Of Metaphysical Sciences, they said that there is speculation that it might be the "space between" that so many people talk about when speaking of consciousness and how it permeates all things. What if the space between is actually "heavier" than what we think the space between is? I mean, most people would think of "air" or a vacumn as being the space between, but maybe the space between is really "consciousness", which is the glue that holds it all together after all, heavier than all matter itself, even black holes, since physical reality might just be an imagining in the mind of God. I don't know, something to think about. They have some cool speculations about it in one of their courses at the metaphysical sciences school I go to. Of course the cosmos class at the college did too! No one really knows what the stuff is!

Very thought provoking post! In shamanism, we commonly journey to the spirit realms, which I know to be enormous in comparison to the physical realm...many many times larger, in fact. Along the lines of your post, what if everything in the spirit realm has the weight, mass, and gravity that everything in the physical realm does, AND exists in some form in the physical plane? That would certainly explain the 90% of matter that we can't see in the physical realm!

Thank you for the post!

Welcome to the forum and thank you for the very interesting thought provoking post.

I just want to say I find this thread really great....and like LK..' welcome ' to the dancing daisy.

After giving it very careful consideration, observation and experimentation, I have come to the realization that it must be duct tape. After all, duct tape, like the Force, has a light side and a dark side, and (again, like the Force) it holds the Universe together.

I always thought it was chocolate ice cream !..It's Dark, and it don't Matter when you eat it !

Apparently, the existence of Dark Matter has been 'proven' ...

Of course, which Science, one idea is as true as the next one which is truer, still it is an important observation ...
