The most direct proof of all: If a theory does not have ANY conflicts with reality (which have to be "explained away" through clover nonsense)... it is more likely to be true than a theory which is bursting with self- contradictions and tied together with the rubber bands of the mind (nothing is absolute- ly true beyond all doubt, of course, because, in the end, we may all be mad). But study: http://physics.sdrodrian.com The text there not only explains where people like Einstein went wrong, but there you will also find the reason for (cause of) gravity, inertia, and many things for which there is no explanation elsewhere... And then at last you will finally understand even why it is that a spinning gyroscope seems to "magically lose the bonds of gravity" [ see http://www.keelynet.com/gravity/gyroag.htm ] Well, there is no magic in this world, only the ignorance of the real cause for the effect. Go thou TO http://physics.sdrodrian.com And finally get rid of some of your ignorance. The reason present "understanding" is a mess of convoluted, self-contradictory, and sci-fi nonsense is because "present understanding" is trying to explain a car in terms of an elephant. It is no different than when "now discredited understanding" was trying to explain the Solar System in terms of the universe orbiting the earth ("a mess of convoluted, self-contradictory, & sci-fi nonsense" there too, as you know). But ONCE you recognize the true nature of the universe (the way the universe REALLY is working)... then everything "fits in" and "everything makes perfect sense." In other words: There are no more self-contradictions possible (once you describe an elephant in terms of an elephant... you can never again be left trying to "fit" an internal combustion engine into the way it works, or vice-versa). It will take quite a lot of time before people let go of the present nonsense and come to accept and finally understand that "the visible universe" is something akin to the eternally- shrinking singularity of a black hole. [First people will have to tweak their understanding of the fact that velocities are NEVER absolute and ALWAYS relativistic, and that "singularities" are theoretical absolutes which don't have any relationship whatsoever with reality... and a few other "tweaks," all minor really.] But they eventually will, because there simply is no other choice. (One can only deny the moon is in the sky... only so long.) And you can be one of the first, S D Rodrian http://poems.sdrodrian.com http://physics.sdrodrian.com http://mp3s.sdrodrian.com All religions are local. Only science is universal. The Universe, Expanding Beyond All Understanding By DENNIS OVERBYE June 5, 2007 When Albert Einstein was starting out on his cosmological quest 100 years ago, the universe was apparently a pretty simple and static place. Common wisdom had it that all creation consisted of an island of stars and nebulae known as the Milky Way surrounded by infinite darkness. We like to think we're smarter than that now. We ALWAYS like to think that we're smarter than we are. But I suspect the truth is that we've gone downhill since the Stone Age. --SDR We know space is sprinkled from now to forever with galaxies rushing away from one another under the impetus of the Big Bang. Bask in your knowledge while you can. Our successors, whoever and wherever they are, may have no way of finding out about the Big Bang and the expanding universe, according to one of the more depressing scientific papers I have ever read. If things keep going the way they are, Lawrence Krauss of Case Western Reserve University and Robert J. Scherrer of Vanderbilt University calculate, in 100 billion years Whoa! This goomer believes we're going to be around 100 billion years from now! I got $10 bucks sez we don't make it to the end of this century. --SDR the only galaxies left visible in the sky will be the half-dozen or so bound together gravitationally into what is known as the Local Group, which is not expanding and in fact will probably merge into one starry ball. Unable to see any galaxies flying away, those astronomers will not know the universe is expanding and will think instead that they are back in the static island universe of Einstein. As the authors, who are physicists, write in a paper to be published in The Journal of Relativity and Gravitation, "observers in our 'island universe' will be fundamentally incapable of determining the true nature of the universe." The same is true today, where today's astronomers look out and misinterpret "what they see" into being "all there is." Thereby also remaining fundamentally incapable of determining the true nature of the universe. [see SDR comment on Stone Age summit of our I.Q.s] Thankfully, there is one human being left who still uses his brains instead of his i'balls to determine the true nature of the universe. Visit: http://physics.sdrodrian.com It is hard to count all the ways in which this is sad. Nonsense. It's hilarious! Forget the implied mortality of our species and everything it has or has not accomplished. Life is what it is. "Live you life & think it nice." In the end, the rocks will not mourn ye. And, to one dead, the three seconds after one's death are the same as all the infinity that hath ever been & will ever be. --SDR If you are of a certain science fiction age, like me, you might have grown up with a vague notion of the evolution of the universe as a form of growing self-awareness: the universe coming to know itself, getting smarter and smarter, culminating in some grand understanding, commanding the power to engineer galaxies and redesign local spacetime. It is a common misconception that evolution is always upwards & onwards. While the truth is that it is often off to some side dead end, and even backwards into greater barbarity/morality. --SDR Instead, we have the prospect of a million separate Sisyphean efforts with one species after another pushing the rock up the hill only to have it roll back down and be forgotten. Worse, it makes you wonder just how smug we should feel about our own knowledge. "There may be fundamentally important things that determine the universe that we can't see," Dr. Krauss said in an interview. "You can have right physics, but the evidence at hand could lead to the wrong conclusion. The same thing could be happening today." Hello! ... http://physics.sdrodrian.com The proximate culprit here is dark energy, which has been responsible for much of the bad news in physics over the last 10 years. This is the mysterious force, discovered in 1998, that is accelerating the cosmic expansion that is causing the galaxies to rush away faster and faster. The leading candidate to explain that acceleration is a repulsion embedded in space itself, known as the cosmological constant. Einstein postulated the existence of such a force back in 1917 to explain why the universe didn't collapse into a black hole, and then dropped it when Edwin Hubble discovered that distant galaxies were flying away - the universe was expanding. There ya go: Human stupidity in a single paragraph! The fact IS that the universe IS collapsing into a "black hole." The fact that "we" are living in its singularity blinds us to that fact (unless you are griviously a throwback to when we were Stone Age smarter). The fact [how many facts is that already?] ... the fact that "velocities" are relativistic, and NOT absolute, blinds us to the fact that our fragile lives can exist AS the matter of such a universal singularity (which we experience at such close-up a magnification as to make us lose all perspective of its singular nature). --SDR If this is Einstein's constant at work - and some astronomers despair of ever being able to say definitively whether it is or is not - the future is clear and dark. In their paper, Dr. Krauss and Dr. Scherrer extrapolated forward in time what has become a sort of standard model of the universe, 14 billion years old, and composed of a trace of ordinary matter, a lot of dark matter and Einstein's cosmological constant. Why, O why can't these clever chaps work on the third race at Santa Anita instead? --SDR As this universe expands and there is more space, there is more force pushing the galaxies outward faster and faster. As they approach the speed of light, the galaxies will approach a sort of horizon and simply vanish from view, as if they were falling into a black hole, Everywhere we are surrounded by a black hole, and these "geniuses" can't seem to glimpse hair nor hide of it! --SDR their light shifted to infinitely long wavelengths and dimmed by their great speed. The most distant galaxies disappear first as the horizon slowly shrinks around us like a noose. A similar cloak of invisibility will befall the afterglow of the Big Bang, an already faint bath of cosmic microwaves, whose wavelengths will be shifted so that they are buried by radio noise in our own galaxy. Unless a piano falls on your head. Then it won't matter even whether the movers had insurance or not. ---SDR Another vital clue, the abundance of deuterium, a heavy form of hydrogen manufactured in the Big Bang, in deep space, will become unobservable because to be seen it needs to be backlit from distant quasars, and those quasars, of course, will have disappeared. Eventually, in the far far future, this runaway dark energy will suck all the energy and life out of the universe. A few years ago, Edward Witten, a prominent theorist at the Institute for Advanced Study, called a universe that is accelerating forever "not very appealing." Dr. Krauss has called it simply "the worst possible universe." Ah! Another goomer who's just now realized that the universe a trillion billion years from now will be inhospitable to the butterflies in his backyard: What will his little son collect then?! -- SDR But our future cosmologists will be spared this vision, according to the calculations. Instead they will puzzle about why the visible universe seems to consist of six galaxies, Dr. Krauss said. "What is the significance of six? Hundreds of papers will be written on that," he said. Wait a minute: What kind of stars are these that seem to be existing a trillion years from now to keep our Sun company? --SDR Those cosmologists may worry instead that their galaxy cloud will collapse into a black hole one day and, like Einstein, propose a cosmic repulsion to prevent it. Ya mean like the "dark energy" which the current crop of ignoramuses are proposing today for the acceleration of the universe's expansion? Hmmm... --SDR But they will have no way of knowing if they were right. Here's a hint: If there's not one (!) single fact contradicting your proposal, it "may" be right [go study http://physics.sdrodrian.com ] And if there is no end of new facts seemingly contradicting your Big Bang... it's blown up: Let it go already. Life is cruel. Become a cobbler like your father told you. --SDR Although by then the universe will be mostly dark energy, Dr. Krauss said, it will be undetectable By the only instruments "dark energy people" will be able to construct then: those also only made of dark energy. [These are your brainiacs at work... on account of all Stone Age smart guys are dead now. Evolution having devolved.] --SDR unless astronomers want to follow the course of the occasional star that gets thrown out of the galaxy and is caught up in the dark cosmic current. But it would have to be followed for 10 billion years, he said - an experiment the National Science Foundation would be unlikely to finance. "This is even weirder," Dr. Krauss said. "Five billion years ago dark energy was unobservable; 100 billion years from now it will become invisible again." Oh, I'm ... sorry ... where did you say that polaroid of dark energy is? I must've missed that one. What? You say we know it "exists' NOT because we have a bit of it in a lab but because we have looked at the universe (obviously ALL THERE IS) and "see" that it is "THE ONLY possible solution" to the problem (having also consulted God, and all the angels--in case God too is an ignoramus)...? --SDR It turns out that you don't actually need dark energy to be this pessimistic about the future, as Dr. Krauss and Dr. Scherrer point out. In 1987, George Ellis, a mathematician and astronomer at the University of Cape Town, in South Africa, and Tony Rothman, currently lecturing at Princeton, wrote a paper showing how even ordinary expansion would gradually carry most galaxies too far away to be seen, setting the stage for cosmic ignorance. I'm sorry, but I do not believe that even after a billion years of ever more growing ignorance we could possibly be more ignorant than we are right now. I just don't believe it. --SDR Dark energy speeds up the picture, Dr. Ellis said in an e-mail message, adding that he was glad to see the new paper, which adds many astrophysical details. "It's an interesting gloss on the far future," he said. James Peebles, a Princeton cosmologist, said there were more pressing worries. We might be headed toward a universe that is "asymptotically empty," he said, "But I have the uneasy feeling that the U.S.A. is headed into asymptotic futility well before that." You might object that the inhabitants of the far future will be far more advanced than we are. I personally believe they will have pet monkeys instead of dogs. Don't laugh, this is a significant advance. ---SDR Maybe they will be able to detect dark energy - or the extra dimensions of string theory, for that matter - in the laboratory. Maybe they will even be us, in some form or other, if the human race manages to get out of the solar system before the Sun blows up in five billion years. Man! This goomer doesn't even know that the Sun isn't going to blow up but gently inflate into a red giant! Is he the panhandler I gave that nickle too outside The New York Times building? --SDR But if relativity is right, they won't be able to build telescopes that can see past the edge of the universe. In five billiiioin years? Man, in 5 billion years Americans will have probably come up with the self-cooking dog-on-a-stick. (And Muslims will probably even start believing the earth isn't flat after all--Or at least stop chopping off the heads of people who say they no longer believe it.) Okay, so I'm an optimist. --SDR It's not too late to start thinking about sending out the robot probes that could drift down through alien skies eons from now with, if not us or our DNA, at least a few nuggets of wisdom - "What does it say, Ork?" "It says, 'Nixon was right.' Korc." --SDR that the world is made of atoms and that it started with a bang. "Who/whatever they are/we They had a sense of humor, Korc. Qua, qua, qua, qua, qua!" --SDR The lesson in the meantime is that we don't know what we don't know, and we never will - a lesson that extends beyond astronomy. Einstein once said, "The Lord God is subtle but malicious he is not." I always knew Einstein would've made a great Pope. (If it wasn't for the fact that it would've been hard for him to fit his Afro even inside those Chess hats popes wear.) --SDR I wondered in light of this new report whether it might be time to revise that quotation. Max Tegmark, a cosmologist at the Massachusetts Institute of Technology, told me the problem was not malice but human arrogance - a necessary but unfortunate condition for scientific progress. "We have a tendency to put ourselves at the center of the universe," he said. "We assume all we see is all there is." But, as Dr. Tegmark noted, Big Bang theorists already suppose that basic aspects of the universe are out of sight. NOTE: Admission by BBers that they don't know. But that they KNOW what they're talking about when they're talking about what they don't know. No, I said, "Who's on first?" --SDR The reason we believe we live in a smooth, orderly universe instead of the chaotic one that is more likely, they say, is that the chaos has been hidden. According to the dominant theory of the Big Bang, known as inflation, an extremely violent version of dark energy blew it up a fraction of a second after time began, stretching and smoothing space and pushing all the wildness and chaos and even perhaps other universes out of the sky, where they will never be seen. This is the "beach wave" analogy theory of everything. THERE IS NEVER ANYTHING NEW IN THE HUMAN MIND. --SDR "Inflation tells us we live in a messy universe," Messy minds tell us we live in a messy universe. A clear mind [ http://physics.sdrodrian.com ] shows us we live in a simple, straightforward universe. Dr. Tegmark said. Luckily we never have to confront it. Ignorance is us, or is it bliss? If we are lucky, "we is bliss." S D Rodrian http://poems.sdrodrian.com http://physics.sdrodrian.com http://mp3s.sdrodrian.com All religions are local. Only science is universal. .. |
