Chapt16.12 Limits of distance that light can travel and seen by
telescopes Now I hope I have the correct term used in physics, because there are many terms similar over the issue of light transmission. There is the term Luminosity and then there is the term Intensity, but I think the term I need is Brightness. Brightness is how bright a source appears to a distant observer and depends on distance apart and the luminosity of the source. Now earlier I talked about a telescope seeing Voyager 1 as it is at the far end of the solar system and whether the reflected light off of Voyager 1 makes it visible to our best telescopes. Brightness is an inverse square law so that two identical flashlights, one of them 1 unit distance and the other at 2 unit distance will look 1/4 as bright. Now here is my complaint about astronomers. I do not see them ever doing a limitation on seeing stars and galaxies due to distance and luminosity. Instead, what I see them doing such as Jarrett and Juric and Huchra & Geller is compiling atlases of galaxies and assuming that what they see in telescopes are galaxies 1 billion light years away and 14 billion light years away as seen he http://www.atlasoftheuniverse.com/superc.html http://www.atlasoftheuniverse.com/universe.html You see, to a mathematician the above is very troubling, for the astronomers all assumed that redshift was Doppler and that it measures distance and that if a telescope sees an object with a Doppler redshift that they can say it is 1 billion light years away. But to a mathematician, he must worry first about Brightness of a galaxy at a far away distance. Can any telescope, no matter what kind, actually pull in enough light of a star or galaxy at a distance of 1 billion light years? I would say the answer is no. I would say the limitations of telescopes, no matter what they are, whether the Hubble space telescope or the best ones on the Earth, that none can see anything at 1 billion light years. Now I asked for the Voyager 1 experiment to see whether any telescope and eye witness the spacecraft today, from reflected light on its surface for we do know what it is made of. And through a translation- factor we can estimate the limitations of the best telescope and that we would not be able to see any star or galaxy beyond 90 million light years away, never mind 1 billion light years. But we should be able to arrive at that 90 million light years limitation distance from the concept of Brightness. We know that Space is not really a vacuum but a near vacuum which eventually slows down and even absorbs the light in transit. We know that Doppler redshift is impossible for it violates Special Relativity and so the redshift is a curvature measure, not a distance measure. This means that quasars are just normal galactic-centers lying rather close to Earth in a bent part of space, the cylinder surface analogy. And the redshift is likely to be caused by the gravity-cell each galaxy possesses for the solar system must have a gravity-cell to explain how Sun can travel at 220km/sec yet Earth only 29km/sec. So, with all these limitations: a) Space not a vacuum slowing down light and absorbing light b) Matter distributed rather evenly as in Euclid's Orchard Math Problem would absorb much of the light c) telescopes have an inherent limit on Brightness at a distance d) redshift is curvature of Space, never a distance gauge With all those limitations, why is it that astronomers never start their textbooks or maps in a discussion of the "limit of distance". Why do they blithely fumble and stumble around with hideous assumptions that distance has no limits. So, if I am correct and Huchra, Geller, Jarrett, and Juric are wrong, then all their atlases end at 90 million light years away, and not their 1 billion to 14 billion light years distance. I think the grave problem over astronomy is that such a community never had a leader who had a good supply of logic to guide them, and so every crank and crackpot set up their own shops of compartments of astronomy and the whole of astronomy is the assemblage of these error filled shops. Maybe there are astronomy textbooks that are honest about the science, where they deal straight away with limitations of telescopes and that it is impossible for any galaxy we know of, to be further away than 90 million light years in distance. -- Google seems to have stopped doing author-archives as of 2012.
