| I don't understand Dark Matter behavior very well. So I'll try to understand it by getting analogy of how it may behave on earth Suppose we have manage to acquire a car size junk of Dark Matter and bring it to earth. 1. Would it be subject to gravity? Or would it just float in the air? 2. Would it interpenetrate physical matter meaning would our hands just pass thru it when we try to touch it? In other words, is it solid in the physical sense? 3. What's the arguments against the possibility that Dark Matter is right now interpenetrating the Earth and solar system and we don't see it. I mean, how would the behavior of earth and the solar system differ if Dark Matter are already interpenetrating the entire earth and solar system? 4. I read the following about Dark Matter and want someone to repute or support it "Her distribution shows that she's not subject to gravity, because if she were, her density would decrease at increasing distances from the center of the galaxy. While, observing the universe on increasingly larger scale than a galaxy, more and more conspicuous dark masses have been detected". What the above author is implying is that Dark Matter may be on earth and solar system right now interpenetrating even even in our physical body. What's the argument against it? 5. The author theorized that Dark Matter is 90% of total mass and is "heavy" because it glues physical matter together through gravity. Any counter arguments? 6. This physicist theorist also wrote the following, "... soon after the Big Bang, the observed universe underwent a phase transition, that changed type of matter, and affected fields too. Yet cosmology hasn't realized that the observed universe is just a small portion (10%) of the total mass that then solidified. That event is recorded in many holy texts, such as the Bible, in Genesis, as the "separation of light from darkness". The greater portion didn't solidify at that time and is still co-existing as a "dark" mass, composing many other universes, each one in a different phase of one Substance." "Dark matter composes all the non-solid phases of the Substance" (Further it is written): "Physical matter is the solid state of the Substance. Its solidity is evident in the atomic structure: almost the entire atomic mass is trapped into an extremely small volume, the nucleus, whose radius is 100,000 times less than the whole atom. There is huge "vacuum" between the nucleus and the electrons orbiting around it. This "vacuum" is actually full of energy, physics has discovered. Its empty appearance is due to our limited 5-sense perception. "Vacuum" coincides with dark mass, in my view: it may therefore coexist with physical matter with any atom, although we can't observe it. While physical matter is ruled by ferocious nuclear forces which constrain most of it into the very small nucleus, dark matter is free and doesn't depend on them. It could be organized by different laws.... ." Now can experts pls try to refute or support the above. I'd like to know specially if Dark Matter can be existing right now in our physical bodies and interpenetrating the earth. What's the strong arguments against each one of the above questions. I've spent days thinking of it but can't quite nail it. Thanks. Kyle |

As a physical entity It would act like a SuperSymmetry neutralino - nothing for it to decay into, inherently relativistic, no electromagnetic interactions at all (no way to cool by radiation or scattering), subject only to gravitation. No electromagnetic interactions at all. Invisible and imperceptible. Freely passes through all matter. No interaction cross-section for anything. It rides the shape of spacetime (gravitation). It doesn't agglomerate, either - no mechanism for binding except gravitation. It cannot condense into "stars" because there is no mechanism for cooling during coalescence. No electromagnetic interactions at all. Invisible, imperceptible, freely permeable. All dark matter would do is add to the mass of a galaxy to correct its measured orbital velocity vs. radius. Relativistic particles subject only to gravitation and incapable of cooling will stack density like a loosely bound atmosphere. There is nothing to detect except gross gravitational interaction. Either you are misquoting or the author is blowing it out his bottom. [snip] Your view is at odds with all of physics. Learn something about zero point fluctuations of the quantum vacuum, Casimir effect, Lamb shift, vacuum Rabi oscillations, electron anomalous g-factor... and dark matter. If you possess no empirical knowledge your deductions will be empirical crap.

| Dear Kyle Taylor: "Kyle Taylor" <[Only registered users see links. ]> wrote in message news:[Only registered users see links. ] m... Be sure and vist the links that Sam Wormley provided. Subject to gravity, yes. It would not float in the air. It is not expected to be "touchable". It is "Dark" for the precise reason that light is not affected by it. Presumably then, physical touch, which is moderated by electrostatic forces, would not be possible. Dark Matter was proposed to explain why galaxies spin faster at the edges than their mass would allow. So Dark Matter is expected to be (conveniently) distributed in increasing proportion, right up to the edge of a galaxy. If Dark Matter were interpenetrating the inner solar system, then our determinations of the mass of the Sun, and all the planets would be in error. No argument. We'd just have a disjoint as to what mass is visible and what isn't. There is pretty good agreement with expected mass the Earth *should* have based on its size. And this is looking at atomic masses on up. You might sneak an extra 5% into a planet, but I'd be truly surprised if it were that much. Not observed. A nucleus is bonded protons (and neutrons). Gravity is many orders of magnitude smaller than the electrostatic force, and it is in turn orders of magnitude smaller than the nuclear forces. Yet strong positive charges are held quite close together. From the very small to the size of the Solar System, Dark Matter is pretty much disallowed. At some point Pioneer 10 passed a threshold, where it is remotely possible, some Dark Matter added a very small amount to the mass of the Solar System. There are a number of other very viable explanations for this, including simple friction against slower "solar wind", so don't think this is anything like gospel. The recent CMBR analyses have been cited as evidence that Dark Matter did not exist at that time. Do not spend effort arguing with religious fanatics. Their blindness is infectious. David A. Smith |

I am no sure if it was a complete set or if some were missing. The set is labelled by the darkness of the matter on one side and the hardness of the dark matter on the other side. The set I have is: 6B, 5B, 4B, 3B, 2B, 1B, B, HB, H, 2H, 3H, 4H, 5H, 6H, 7H, 8H, 9H. So all of them are dark but darkness of matter differs from one pencil to the other. EL |

| "[Only registered users see links. ] \(formerly\)" <dlzc1.cox@net> wrote in message news:<c%Zmb.117594$gv5.75387@fed1read05>... Hmm... Suppose a Dark Matter falls from the sky into my bedroom. Would it stay in my bedroom floor or would it pass thru the ground to the centre of the earth. How can something have gravity yet without mass?? Suppose I made a baseball bat out of Dark Matter and hit a monkey. It won't affect him, yet when I drop it, it would fall to the center of the earth?? Furthermose, supposed many dark matter reaches the earth and it gravitates to the core of the earth. Would it get larger and larger (much like filling a cup with water until it fills up) finally occupying the mantle and crust of the earth to reach the surface or would it just stay at the core interpenetrating amongst themselves? If its the latter, is there a limit to the interpenetration density. Would the Dark Matter of an entire galaxy fit in a small cup or basin intepenetrating amongst themselves? Kyle |
