Teempakguy:
i think the universe is in more than 3 dimensions, just like a pool of water, the part we can see is just the surface, the deep, just like dark matter, can't be seen. just like the deep, they are not affected by light because they are not on the surface. . ..

amaa4real:
From what i read the universe is of four dimension with time as the 4th dimension and also three dimension is used for location of place in space but the four dimension is used for locating event. concerning the dark matter that makes the black hole i read that it gravitational force is not enough to force the gallaxy into orbit so which force is responsible for the upkeep

Blakjewelry:
The issue of dark matter is a complex one. For me I look at it In three ways,
1. I think maybe something might be wrong with the maths that gave rise to the theory of dark matter.
2. Maybe an unidentified particle which has very weak interaction with matter.
3. Diffusion of particle, matter or space time around the regions between our universe and another universe, remember you don't expect matter from our universe and the one from an alternate universe to behave the same. On a second thought even if we assume they are the same the change in dimension will definitely change the way they react.

Teempakguy:
i agree with two. you know, it may that that undiscovered particle doesn't react with protons. may be it just absorbs it. . .

Blakjewelry:

If it absorb the effect would have being felt, so far nothing of such.

Teempakguy:
true, i agree. how about this, they don't react to photons because they their somewhat like subatomic glass.

Teempakguy:
Physicists are currently debating that the universe may have up to eleven dimensions. i support this motion on the grounds of the fact that light waves and water waves are infact transverse. and if water waves only skim the surface, i suggest that this is also what light does. thereby concealing the dark matter in the higher space time.

amaa4real:
11 dimensions? Can please Elaborate

Cc blakjewelry.

I think dark matter may actually be the product of hawking radiation.

AgentOfAllah:


You mean black holes, not Hawking radiation? Hawking radiation is so infinitesimal you cannot possibly detect its gravitational pull. If you meant black holes, then hawking radiation will be a product of dark matter, not the other way around.

Teempakguy:
okay, yeah. Black holes.

I also have another theory. that we share universes. And gravity is the only force that permeates them all.

Hence, gravity from a star in some other universe affects our own galaxy.

AgentOfAllah:


Your suggestion may be valid, but following the principles of Occam's razor, it is superfluous!

timonski:
The question is: Thus dark matter even exists? I mean is it a RATIONAL explanation to anything?

AgentOfAllah:

Dark matter isn't an explanation, it is an observation, as such your question makes no sense. Asking your question is analogous to asking if wind exists. You may not know the content of the wind, but you feel the pressure it exacts, thus you know it is real. Likewise, we feel the gravitational pull of dark matter, and though we don't know what constitutes dark matter, its existence is, ipso facto, indisputable!

timonski:

guy wind is simply "Air in motion", and we all know the constituents of air.
You pseudo-scientists observe gravity and you quickly scream DARK MATTER! you say it is an indisputable fact. Then how come dark matter is still a theory?

AgentOfAllah:


Although, it is both your right and prerogative to come across as ill-informed, you have called into question, my scientific acumen, which is what has necessitated my response. I'll now have to school you on dark matter.

Your comment betrays a definite lack of understanding of the fundamental forces of nature! There are four of them, namely, the strong and weak nuclear forces, electromagnetic and gravitational force. Efforts of particle and nuclear physicists have helped us unify the weak and strong nuclear forces, as well as the electromagnetic force. Essentially, the nuclear forces decay into electromagnetic force at low energies (<100GeV). This has led physicists to[b ]believe[/b]

Sorry to say, but this is a load of bull. In science we don't BELIEVE. Belief is the hallmark of religion. In science we try to rationally explain any theory, not this. This is why we have so many sects in mainstream science like bigbang theorists, string theorists( like teempakguy and co), relativists, quantum physicists. And we now have religious teachings like:
* timeless, spaceless singularity(God)
* big bang, big bounce(creation)
* big crunch(the apocalypse)
* 0D particles(spirits)
* 1D strings, blackholes, white holes, dark energy, dark matter(angels and demons?)
* Anti-matter(satan)
* Time dilation, space expansion, length contraction, time travel, wormholes( straight outta the comics) etc.

Teempakguy:
I believe the word believe here is rather relative.

Anyway, dark matter is a theoretical explanation for the formation of galaxies. A very strong amount of centrifugal force is needed to keep the stars spinning. In a disc form that the galaxy has.

Gravity is far too weak a force to provide the centrifugal energy. With the amount of mass available in the galaxy. So, a leading theory is that there is actually enough matter in the universe to propagate gravity. But, that it is unobservable by human instrument.

Also, I wouldn't refer to Satan as antimatter. They are an entirely different concepts.
Also, I don't think I've ever heard of a dimensionless particle before. How would such then exist?

AgentOfAllah:

Thanks for your clarification. That guy is clueless, and has just the right size of ego to deceive himself into believing he actually knows what he's talking about!

As I earlier stated, dark matter is a direct consequence of the fact that force is intricately linked with matter. Force of gravity is felt, thus, matter exists. We don't know the nature of the matter, so we call it dark.

Actually, stars are spinning in relative vacuum, so you don't need centrifugal force at all, all you need to sustain their axial rotation is angular momentum from the initial explosion from which the stars emerged. In any explosion, there is bound to be a few particles that are expunged with angular momentum. There are roughly two types of celestial bodies, those that form oblate spheroids like stars, planets, moons, etc. These left an explosion with angular momentum and they're are still spinning today (conserving the law of inertia). The other types are debris like comets and meteors that don't spin around their axes, but nevertheless, continue to move. They only stop when they collide with bigger bodies with large enough gravity to pull them away from their trajectory. Sometimes, we experience this as meteor showers on earth.

gravity is not a polar force, so it has no tendency to cause angular momentum on its own. The reason we are orbiting around (not moving straight towards) the sun is because the earth and the sun had an angular momentum against each other from accretion. Thus, there is an equal centrifugal force that pushes us away from the sun, just as gravity pulls us into it. Both forces balance out and keep us in orbit.


Anybody that refers to Satan as antimatter is a complete nutcase!
