Dark Matter

Just a few questions. Where is dark matter in the universe? Is it just observed 'inter-galactically' sorta thing or is it said to construe throughout all the nooks and crannies of the universe. When they say a galaxy has fives times as much mass as expected and they find there is this dark matter, in what regions of the galaxy is dark matter observed?

The existence of matter that doesn't reflect light

I believe that dark matter is believed to be omnipresent in the universe. Dark matter does not reflect light, and so it cannot be observed directly. It's gravitational effects on surrounding matter are the only things that can be observed.

So how do you examine dark matter apart from its effect?it does more than not reflect light.Saying it does not reflect light does no describe it.It only appears to have effect by its mass and what is mass? If we have the effect of mass but we have not got the visible mass, just saying i believe it does not reflect light is not carrying the philosophical debate forward.We are dealing with unknowns, surely a good reason to speculate.Could this mass , vibrations, exist in other universes, invisible but by its presence effectual..??

Saying that dark matter does not reflect light does describe something about it. What is mass??? Come on, you know what mass is. I am not merely saying that I believe it doesn't reflect light. If dark matter does exist, and we have every reason to believe it does, then I know that it doesn't reflect light. If it reflected light it would be visible.

I believe that your last sentence shows that you are still dealing with the parallel universe "theory". As I said before, that "theory" is a result of the misinterpretation of the phenomenon known as quantum leap. If you believe in the parallel universe "theory", then according to the so-called theory, parallel universes have no effect on our universe.

Im not assuming anything by others proposed theories.You have supposed i am talking about your conception of a parallel universes, i have no view on this theory, its not the subject of debate.I am only commenting on the possibility that this the majority of experienced mass is not visible in this universe and it could be a reflection of multi verses corresponding to the total, divided by the assumed amount of mass observed in this universe.This could give a possible amount of other universes or should i say other views of this universe.

I'm not a physics expert, but I think your physics are wrong. You seem to think that it could be a reflection of a multi-verse, but you want to see if others agree. I would advise that you speak to a physicist.

As physics has no theories to explain dark matter or its invisibility, i dont think we have much chance of that.What physics do you think im referring to when i muse? Thanks xris..

Invisibility can be explained by the bending of space-time. This is how invisibility is currently done in 2D right now!

Not very practical yes, but same concept could apply here in this thread of musings in that the bending of space-time might be all that's happening. What if these pockets of space in which there is dark matter is really just areas of space where light doesn't reach because space-time has been bent in a certain way. Perhaps an emergent kind of bending occurs when there is a specific amount of mass present in a topological area like a galaxy perhaps?

I'm sure physicists have thought about this, and ruled stuff like this out but I'd always like to learn why.

whatever it has or is happening its happening on a enormous scale and why is it invisible and other matter not.It has to be made of a certain strange matter or it is vibrating in a diferent realm of existences.I do believe that it is only relevant by its gravitational effect, it can hide its face but not its weight.I think Hues right we need a physicist to bring a bit of reality into the debate.

whatever it has or is happening its happening on a enormous scale

I know, that's kinda my point in the matter here. If dark matter only occurs on a macro scale then I doubt its matter. But this is where I feel we need the empirical facts here.

Also, I wonder what you mean by universes colliding to produce the phenomenon of dark matter. If two universes collide I can't possibly imagine dark matter would be the only effect of such a phenomenon.

Xris:), when you introduced the multi-verse concept I was assuming (and pardon the assumption) that you were on a train of thought involving universes having their influences coalesce with each other(to put it more technically then 'colliding').

However, you seem to have another idea in which we can have a reflection of another universe on our universe. I don't really know what you mean by this otherwise.

So people in another room can influence people in your room, but not you yourself. The only reason you know there are other people in other rooms is their influence on the other people in your room.

How do you know if the influence on the other people in your room is coming from another room? Perhaps it is all the workings of the same room.
