Wikipedia makes no stab at explaining a cause. Now I am straying a bit here by noting that the intensity can be thought of as divergence where perhaps these two concepts are the same fundamentally. And another issue that catches my eye is that intensity is inverse square just as Coulomb and gravity are inverse square. Â*So can we say that the reason or cause for intensity or divergence of regular light is because it is moving inside an Atom Totality where the Space is charged and so the intensity of light would have to follow the same law or force as that of Coulomb and be inverse square? Whereas in a Big Bang theory, Space has no charge and thus the intensity of light in a Big Bang should not follow a inverse square but rather follow what laser light follows-- a linear relationship with distance. Now I am not understanding or knowing as to why a laser light, the individual photons seem to be linked or tied together so as to stay on course and not diverge as regular light with an inverse square? Sort of reminds me of the Bell Inequality of linked light. Has any physicist, dare explained how it is that laser light seems to stick together as if the light waves are tied or connected and why they have overcomed their tendency to diverge as regular light diverges into a inverse square? At the bottom of the page is a link to a calculator: http://www.pseudonomen.com/lasers/calculators/ Here is someone asking almost exactly the same question as you did earlier, plus some nontechnical information about detection range of lasers the lunar retroreflector experiment: http://answers.yahoo.com/question/in...6192437AAON4zA Yes, they corrected me on the diffusion, for it is divergence. But I wonder what is the physics explanation of what causes divergence? I think it is due to the fact that Space is charged as in an Atom Totality and that causes the intensity of light formula to end up being one and the same as the Coulomb force of an inverse square with distance. Now since the laser light divergence is linear and not inverse square, reminds me of the Weak Nuclear force of physics which is linear. If I remember correctly the Strong Nuclear force rules are more of a inverse cube rule, not linear and not inverse square. So here, we may have a example of light behaviour that is traced to the four forces of physics, and that all these light behaviour concepts of intensity, divergence, refraction, diffraction, diffusion, coherence and hundreds of others, are all manifestations of the 4 Maxwell Equations. Now has anyone shown how all of Optics is a subset of the 4 Maxwell Equations? I suspect it would be easy to prove since Optics is only about EM. So, if intensity is equivalent to divergence, would mean that intensity is merely just the Coulomb Force as light moves in space.

Â* Â* Â* Â* Â* Â* Â* Â* Â* Â* Â* Â* Â* Enrico So now, I can really make it very easy on myself about the Telescope being the very best distance tool of astronomy. If I were to conjecture that Space of the Cosmos is not a 100% clean space, just as it is not a 100% vacuum in space. So that there is muck or grime or dirt or imperfections throughout space and as we go further in distance we encounter these imperfections. Now these imperfections are actual atoms of hydrogen, or they can be other simple particles. So that light from a star as it travels through Space, is diverged because it constantly runs into some of these atoms or particles. Call it divergence due to grime or muck of Space. And this grime and muck are not randomly situated in Space but uniform in Space. This would mean that all physical energy sources whether a flashlight or a Supernova if their light travels far enough through this muck and grime, that eventually you achieve such a distance that you can no longer see the flashlight nor the Supernova. So then when I guess that 400 million light years is the edge of the Cosmos, I mean that the most powerful Supernova light cannot survive after travelling through 400 million light years of the background muck. Now we have the Background Cosmic Microwave Radiation, and I am calling for a Cosmic Background of Muck and Grime spread uniformly throughtout the Cosmos as hydrogen atoms or other particles which would prevent the viewing of a Supernova beyond 400 million light years away. Now the astronomers allege that SN2003fg Bootes is 4 billion light years away and SN2005ap Coma Berenices is 4.7 billion light years away But in their alleging they assume Space is empty, crystal clear and containing no muck and grime for light travelling through Space for a long time and a long distance. And come to think of it, I suspect noone believes Space is a vast clean Space with no atoms of hydrogen uniformly distributed through space to interfer with long distant travelling light waves. Now the reason that all telescopes on Earth have a upper limit of seeing distance is because of the grime and muck in the air that no matter how large, how precise or anything else about the telescope, that the dirt in the air will prevent you seeing a supernova at a huge distance away from Earth. So, how do I reconcile this Muck constraint with the alleged billion light year away Supernova reported? I reconcile it by saying that the Supernova occurred but since they were determined distance by Doppler redshift, that they got that distance all wrong. That the true distance of both those supernova in Bootes and Coma Berenices were at a distance between 200 million to 400 million light years away. Now having dirt in the air or Space is the easiest way for me to determine an Upper Limit of distance using the telescope as a distance tool. But there are other concepts that cause a limit to distance, such as the loss of intensity over distance.

Â*The formula above describes a constant beam opening angle. Â*A emitting source with constant opening angle still falls off in intensity with the square of distance. Â*I.e. *inverse square* still applies. Â*Since your conclusions are based on a faulty premise, the conclusions are not relevant. Do you know what "linear" means in mathematics as opposed to inverse square? Probably not. Again, do you ever stop to think about whether your thoughts are true or false with simple known experiments. The reason a laser beam is used to reflect off a mirror on the Moon planted by the astronauts decades ago is because the laser beam is not a inverse square with distance. Otherwise, just use a white light flashlight for the roundtrip to the Moon. Now I wonder what "physically" causes divergence? Wikipedia makes no stab at explaining a cause. Classically, it's Huygen's principle. Â*Formally, it's the behavior of Maxwell's equations. And you do not know the Maxwell explanation, I take it. I already started the explanation by saying that the Coulomb law is inverse square. So intensity is inverse square and intensity is equivalent to divergence of light. So to have a Universe where the intensity of light is the same inverse square as the Coulomb law, means that Space of the Universe has Charge, and is inside a atom. The Big Bang theory would not dictate that intensity must be identical to Coulomb law for obvious reasons because it is senseless to have Charge for the overall Cosmos in a Big Bang theory. The Atom Totality theory dictates and demands that the Optics of light inside an Atom Totality have intensity equivalent to divergence and then identical to Coulomb. Demands it because well, Space in the Atom Totality is charge itself. Space = Charge and Charge = Space. So, Craig, care to provide meat to your sentence? Care to provide what you believe the Maxwell Equations explain how divergence of light occurs? If I were to conjecture that Space of the Cosmos is not a 100% clean space, just as it is not a 100% vacuum in space. So that there is muck or grime or dirt or imperfections throughout space and as we go further in distance we encounter these imperfections. Now these imperfections are actual atoms of hydrogen, or they can be other simple particles. "Atoms" have known effects on propagating light. Â*"Simple particles" - such as dust - have known effects on propagating light. Â*Neither of them causes redshift of the center wavelengths of spectral lines. Now the above was written in 2010 at a time in which I did not have the Maxwell Equations as axioms over all of physics, but one can see that I was using the Maxwell Equations as a bulwark of physics. Notice especially that logical tie up of having astronomy telescopes following a inverse square law for the motion of light in space implies Space is the Maxwell Equations and thus the Universe is a big atom, not a Big Bang. In many cases, the redshift of an object is actually detected - or limited - by observing the effects of intervening gas between a bright source and us. Â*The gas itself causes absorption at specific known rest wavelengths. Â*Measuring the redshift of those wavelengths allows one to set a lower limit to the redshift of the source. Â*So, contrary to your claim, astronomers do indeed consider the effects of "atoms" in space. Well a Doppler Redshift of light waves violates Special Relativity, so we throw out Doppler Redshift as a distance measure. Even Hubble threw out the Doppler Redshift later in his career in astronomy. The only reason others never followed his lead is that they are too lazy in work and too illogical in mind. This would mean that all physical energy sources whether a flashlight or a Supernova if their light travels far enough through this muck and grime, that eventually you achieve such a distance that you can no longer see the flashlight nor the Supernova. "Tired light" has been ruled out for years. Â*Ned Wright's page discusses this. CM This is 2013 now and the above was 2010. Since then I have an easy explanation for redshift of light, which measures curvature. It goes like this: Planet Earth cannot be bound by gravity to the Sun when the Sun is moving at 220km/sec in Space and Earth at 29km/sec. So to resolve that discrepancy, the Sun forms a EM-gravity cell and this cell rotates on the solar axis with a rotation speed that carries Earth around in orbit of its 29km/sec plus a factor of 220km/sec. So that every star, every galaxy has a gravity EM-cell around it. And when light travels through all these gravity cells, it is bent more and more to the red wavelength. I do not need tired light to explain redshift. I need only curvature of Space, caused by gravity cells. Now Craig prides himself as being an astronomer. But has Craig ever asked himself, how could it be, that Newtonian gravity and General Relativity can explain how Earth moving at 29km/sec while the Sun is moving at 220km/sec, how in the world could General Relativity ever keep Earth attached to the Sun in its ecliptic, because with those sort of speed differences, the Earth would now be where the Kuiper belt is in a 100 years elapsed time. So is Craig's knowledge of the motion of Sun and planets a parrot's knowledge, or is Craig able to satisfactorily answer how General Relativity can reconcile 220km/sec with 29km/sec. For me, GR is a fake theory and can never reconcile those speeds. Only the idea that gravity is EM gravity and the Sun forms a EM-gravity cell that rotates in Space. -- More than 90 percent of AP's posts are missing in the Google newsgroups author search starting May 2012.
