THEY'RE MADE OUT OF MEAT by Terry Bisson "They're made out of meat." "Meat?" "Meat. They're made out of meat." "Meat?" "There's no doubt about it. We picked up several from different parts of the planet, took them aboard our recon vessels, and probed them all the way through. They're completely meat." "That's impossible. What about the radio signals? The messages to the stars?" "They use the radio waves to talk, but the signals don't come from them. The signals come from machines." "So who made the machines? That's who we want to contact." "They made the machines. That's what I'm trying to tell you. Meat made the machines." more.... http://www.terrybisson.com/page6/page6.html apologies for the off topicness of this post.
One explanation for dark matter is it has a connection to relativistic mass. Relativistic mass will form/increase as mass increases velocity toward the speed of light. It is predicted by special relativity. If we decelerate the mass, the induced relativistic mass is released. The existence of dark matter suggests that relativistic mass is conserved in the form of dark matter and energy. One way to complete the universal dark matter balance is to begin the universe with only energy. If we begin with only energy, that means the only reference that will exist within the universe would be the speed of light reference. If we condense energy into matter, then speed of light energy reference will need to drop below C since matter cannot exist in a C reference. The condensation of matter will create relativistic mass, since reference is close to C, and require the release of excessive relativistic mass during the C to C- transition. The amount of dark matter/energy will be proportional to the loss of relativistic mass/energy, which is connected to the deceleration between C and C- as stable mass appears. To test this theory we might accelerate mass in a particle accelerator and then put on the brakes to shed relativistic mass. Next, we see look at the shedding for traces of what we call dark energy and mass. It may require an energy condensation into mass which may be harder to duplicate.
Since you are talking about components, mechanisms, and processes imbued in the EEMU Hypothesis . . . I refer (without self-promotion or trolling - Mod) you to that thread (in Alternative Theories) on Sciform
Positive mass and negative mass can exist in the same space-time. In my opinion, Dark matter is negative mass (energy). m=E/c^2. 1. Positive mass and negative mass can exist in the same space-time. All the while, the field of physics did not seriously consider the possibility of existence of negative mass at the general state. The standard explanation about negative mass is, if energy level of negative exists, that the state of low energy is stable, and the lowest state of energy is minus infinity, so the positive mass of all emits energy, and it will transit to the energy level of minus infinity, and the universe will collapse. However, at the present, our universe exists without collapsing, so the explanation for this became the strong proof for the nonexistence of the negative mass and the energy level of negative. We have taken this as the natural common sense and teach it to students. At the center of this background, there is the fundamental proposition that "State of low energy is stable". But, we show that the "State of low energy is stable" proposition is an incomplete one, and in case of a positive mass, it is stable at the low energe state, whereas, in case of negative mass, it is stable at the high energy state. Due to this, the problem of the transition of the energy level of minus infinity does not occur, and therefore, in our universe, the existence of negative mass is possible.

This suggests that the halo, dark matter (negative mass) of the external Galaxy could get additional effects of centripetal force to the inner Galaxy. Please Register or Log in to view the hidden image! fig12. Negative mass effect on arms of galaxy. The actual observed spiral galaxy is on the left. Since repulsive effects occur between negative masses in Newton’s dynamics, negative masses will be distributed all over space because it cannot form large mass structures like stars. Negative mass within the galaxy is cancelled out by attraction from large positive mass during the galaxy formation process. Furthermore, the space, other that the galaxy, will maintain the distribution state of negative mass. 1) if we assume that the white empty space is full with negative mass and positive mass at the same density white empty space(0) = (+mc^2) + (-mc^2) =0 2) here negative mass is uniformly distributed over the whole area, so the effect of negative mass on mass m is 0. Remaining positive mass is distributed over the white area on the left at the density of negative mass, and 3) the gravity that uniformly distributed positive mass(same density to the negative mass density) works on positive mass m place on radius r is worked only by the distribution of mass within radius r.- Shell Theorem Please Register or Log in to view the hidden image! fig14. Equal to the degree of gravity that is applied on the equally distributed positive mass within the radius r of the left side. The gravitational effect from negative mass, which functions at mass m is equal to the gravitational effect from positive mass within radius r. Therefore, the effect of negative mass that remains out of galaxy without being offset can make it approximate to the gravity generated by the distribution of positive mass within the radius R in galaxy 3.

Well it is self promotion. An advert on TV starting with "I'm not advertising my product but perhaps you'd like to hear about it!" is still an advertisement. Since this thread is about the number of possible explanations a single mention is going to be allowed but that's it. The list from the OP at least pertains to things which are generally quantifiable in some way, rather than the complete arm waving of things like your work. At least they are trying to be more than someone's vague opinion.
Mod remark: the signal to noise ratio is extremely low in this thread - it is not far from a move to pseudoscience. Posts that are for nothing other than flaming will not be tolerated here either. The usual advice applies - if you have a problem with moderator behaviour, take it to an admin or super-mod by PM, not in the thread.
Prom: THANK YOU! . . . . . I'd recommend a 'move' to Alternative Theories, however . . . Also, are we (members) then not to use the "Report" button to report violations of Sciforum rules? . . . even if violations are by Mods, Super-Mods, or Admin??
wlminex: Your ratio of complaint posts to content posts is about 3 to 1, as far as I can tell. Your reports are received and read, and acted upon if found to be valid. You do not need to also whine in a thread every time you hit the "report" button. Moreover, that is not the appropriate place to complain about moderator actions.
James R: Although THIS is not the 'place' for this response, just exactly what is the purpose of the "Report" button, if not to report misuse (acc/to Sciforum rules) of the member posts to fora and threads - by ANY Sciforum members . . . including Mods and Admin . . . are they not also 'members'? Don't the "Reports" go only to Mods and Admin? for their evaluation? . . .(exception being the ONE TIME I copied a Report to a thread). Thanks for your hard work . . . and Happy New Year! BTW: Should I also make "good reports', when I feel they are appropriate? (see above) Excuse this post if it appears 'whiney" (MOD Note: Posted here in direct RESPONSE to James R's post) wlminex
Hmmm... So your idea is to have a particle accelerator, accelerate particles and then have these particles hit a target so they stop or lose most of their velocity. Another possiblity is to have the accelerated particle hit another particle moving in the opposite direction so that again the particles stop or lose most of the their velocity. So what is it exactly that you think particle accelerators do?
Does this help in this discussion? . . . . MOD: If not, perhaps should move to Religion Thread?? Link: http://arxiv.org/abs/hep-ph/0109031 Genesis Cosmology Authors: Ding-Yu Chung (Submitted on 4 Sep 2001 (v1), last revised 9 Feb 2011 (this version, v3)) Abstract: Genesis Cosmology is the combination of Genesis and a cosmology model for the description of the first three days in Genesis. The first day involves the emergence of the separation of light and darkness from the formless, empty, and dark pre-universe in Genesis, corresponding to the emergence of the current asymmetrical dual universe: the light universe and the dark universe from the simple and dark pre-universe in Genesis Cosmology. The three stages of the pre-universe are the strong, the gravitational, and the charged pre-universes for the emergences of the strong, the gravitational, and the electromagnetic force fields, respectively. The light universe is the current observable universe, while the dark universe is sometimes hidden, and sometimes observable as dark energy. The second day involves the separation of waters from above and below the expanse in Genesis, corresponding to the separation of dark matter and baryonic matter from above and below the interface between dark matter and baryonic matter for the formation of galaxies in Genesis Cosmology. The repulsive MOND force between dark matter and baryonic matter exists in the interface between dark matter and baryonic matter. The third day involves the separation of sea and land where organisms appeared in Genesis, corresponding to the separation of interstellar medium and star with planet where organisms are developed in Genesis Cosmology. Under the normal condition, stars and planets are developed. Under extreme condition such as zero absolute temperature or extremely high pressure, superconductivity and the alternative for black hole appear. Genesis Cosmology is the unified theory that unifies different phenomena in our observable universe.
I don’t understand what you’re whining about. Who cares, if the OP wants to discuss dark matter/dark energy? It's interesting. :shrug: How does Dark Energy Drive the Universe? Saul Perlmutter Leonard Susskind Nima Arkani-Hamed Paul Steinhardt Alan Guth Dark Matter: Just Fine, Thanks by Sean Carroll Besides, I think it’s fun to read the alternative ideas. There was that guy, Dr. HongSheng Zhao, with the Dark Fluid, who proposed that dark matter and dark energy are not separate physical phenomena. There was Professor Jose Senovilla, who proposed an alternative to dark matter and energy. Their model shows that time itself is slowing down. Therefore the far-distant stars, would from our perspective, look as though they were accelerating.

Mod: You have my permission to move to "Alternative Theories" . . . . . if appropriate wlminex ↗ Gravity QGP (dark energy) ↔ VP (dark mass) ↔ (temporary+permanent) 'mass' + residual QGP ↘ CMBR QGP = Quark-Gluon Plasma VP = Virtual Particle CMBR = Cosmic Microwave Background Radiation (Note: Gravity and CMBR should be above and below 'mass' respectively . . . not too good at putting graphics into text)
wlminex: There's no problem with hitting the "report" button. What I said was that you don't have to ALSO post a complaint post every time you do that. No. Our workload is enough as it is.
