Dark Matter: Interperating Data Can Be a Very Hard Task for Scientists Including Galileo And Kepler

I just finished  with Galileo's Sidereal Messenger/ Kepler's Dioptics for the umpteenth time and I marvel at the discoveries made in those first few years after the invention of the telescope. Galileo got so many things right with his observations but the genius Galileo got a slew of things wrong too. Johannes Kepler  the wunderkind that came up Kepler's three Laws of Planetary Motion, got his share of stuff wrong. Some cases in point with these two giants are...
Galileo was trying to figure out why the edge of the moons disk appeared smooth and the rest of the Moon was littered with mountains and valleys.  Galileo wrote:  To this explanation may be added another, namely, that there is round the body of the Moon, just as round the Earth, an envelope of some substance denser than the rest of the ether, which is sufficient to receive and reflect the Sun s rays, although it does not possess so much opaqueness as to be able to prevent our seeing through it—especially when it is not illuminated. That envelope, when illuminated by the Sun's rays, renders the body of the Moon apparently larger than it really is, and would be able to stop our sight from penetrating to the solid body of the Moon, if its thickness were greater; now, it is of greater thickness about the circumference of the Moon, greater, I mean, not in actual thickness, but with reference to our sight-rays, which cut it obliquely; and so it may stop our vision, especially when it is in a state of brightness, and may conceal the true circumference of the Moon on the side towards the Sun. This may be understood more clearly from the adjoining figure, in which the body of the Moon, A B c. is surrounded by an enveloping atmosphere, D E G. An eye at f penetrates to the middle parts of the Moon, as at a, through a thickness, dia, of the atmosphere; but towards the extreme parts a mass of atmosphere of greater depth, E B, shuts out its boundary from our sight. Galileo, using the data he had acquired,  was way off base with this solution. Galileo also originally and erroneously thought  Saturn was a triple system with two smaller planets on either side of the planet.
This is from the preface of Kepler's Dioptics. : For if the earth were banished from the centre of the universe, some fear lest the water should leave the orb of the earth and flow to the centre of the universe ; and yet we see that in the moon, as well as in the earth, there is a quantity of moisture occupying the sunken hollows of that globe ; and although this orb revolves actually in the ether, and outside the centres not merely of the universe, but even of our earth, yet the mass of water in the moon is not at all hindered from cleaving invariably to the orb of the moon, and tending to the centre of the body to which it belongs. So Kepler thought that the Moon had water on it lots of water. Hmmm The Moon does have water but not where he said and not how much he said.

That is the problem with RAW data. The interpretations are as varied as the Universe itself. That might be a little over the top but you definitely get my meaning. They can be varied using the same science available to any thinking human being. This is where Dark Matter /Dark energy comes in. Can it be explained by just baryonic sources such as Brown dwarfs, black holes  and the like.  Or just maybe it is non baryonic in nature?  So if it is non baryonic,  is it cold,  warm or hot  Dark matter? If it is one of those three, could the particles be neutrinos super-neutrinos or even neutralinos. or maybe weakly interacting massive particles etc. or how about theoretical partcles yet to be found? By the way it could be a combination of some or all of the above... or none of it.

It could be one of several gravity theories floating out there (paradox intended) Modified Newtonian dynamics ie  MOND, TeVes, MOG NGT and back reaction theory etc. each one might include the some quantity of Dark Matter to shore up it's point. The latest MOG theory is stand alone in nature. there are many others out there clamoring to stay off the trash pile of dis-proven theories.

I have seen mandates that call for a solution in the next two years or science will have to reevaluate the whole Dark "stuff" scene. I have seen the Ether come up  to explain some of this circa 2006? Are you kidding me?  Do I have a favorite theory? Well, yes I do but my vote hardly counts. What does count  is the hard working scientist of this age striving to make sense out of the many Terra-bites of information continuing to be gathered by oh so many sources. Two years is a short time to sort out all of this.One thing is for certain these next couple of years are sure to be exciting! For the many theories that will go by the way side just remember you are in some very good company.

Until next time

Keep looking up!

    In the continuum of space and time, exists the dichotomy of matter and energy. All things exist as both matter and energy, but are experienced as one or the other.
    As energy, all things exist as wave patterns. Most wave patterns are interferences of simpler wave patterns. The simplest wave forms are those that do not interfere with other waves. These simplest wave forms hold their shape as they propagate. There are three such wave forms.
    The first such wave form is seen in three dimensions as the spherical expansion wave of a bomb blast, and in two dimensions as the circular wave of expansion on the water where a rock was tossed in. The second wave form is seen in three dimensions as the cone of sonic boom following an aircraft traveling faster than sound, and in two dimensions as the V-wake on the water where the boat is traveling faster than the water wave. The third wave form is seen in three dimensions as the propagation torus of a smoke ring and is seen in two dimensions as the double vortexes of an oar stroke on the water.
    The Torus is a particle of discrete exchange, from one point to another. The object exchanges position and momentum. While the spherical wave shows position, and the conic wave shows momentum, the torus shows both at the same time, and has a dynamic finite unbounded reality. The volumes of the cone, sphere, and torus are mathematically related as static objects.
    The Universe is a local density fluctuation. (a wave pulse) On this local density fluctuation wave, lesser wave forms may exist. All simple wave forms are also local density fluctuations, and as such are indeed universes in their own right, where other waves may exist.
    Consider the torus as a universe. Einstein said that gravity is indistinguishable from acceleration. There is both linear acceleration and angular acceleration. Although the torus as a whole travels in a straight line, every local point on the torus travels in a circle and experiences angular acceleration.
    The rubber sheet model of gravity and curved space translates directly to the propagating torus with angular acceleration. Acceleration is downward on the rubber sheet and outward on the torus. The tension field that separates the inside of the torus from the outside holds its shape as a simple two dimensional field of space and time just as the rubber sheet does.
    Experimentally verifiable is that a big fat slow smoke ring generated in a room with very still air will eventually possess a bulge that travels in a circle on the surface of the smoke ring. This bulge, being a gravitational depression, gathers more of the energy of the field toward itself. Finally the bulge gathers enough material to collapse the field and eject a new, smaller smoke ring out in the same direction as the first torus. This collapse is a black hole to the first torus, and a white hole to the second torus, where the axes of space and time in that second torus have reversed.
    While gravity tends to draw depressions together locally on a dynamic torus, even to the point of field collapse, other areas on a torus expand and contract globally as the torus propagates along without regard to local phenomenon on the surface. This is quintessence. The inertia of the torus to propagate is its dark energy. This is a two-dimensional example of the process that we experience in three dimensions.
