cosmology? the metric fluctuates in the infinitely small, then why its principal characteristic, its signature, should remain fixed?
Why was Nicolas Cusa was not condemed for his belief in a radical Neoplatonic cosmology? In the book the Copernican revolution Kuhn says that “Nicholas of Cusa had propounded a radical Neoplatonic cosmology and had not even bothered about the earth as a moving star, like the sun and the other stars, and though his works were widely read and had great influence, he was not condemned or even criticized by his church”. Why was it that this radical theory not condemned by the church and the Copernican theory was? Was it the content of the theory or were the times just different, what makes theories in general dangerous to the church?
What are the objections to plasma cosmology? Many remarkably intelligent people subscribe to the idea that the cosmos is driven primarily by electricity, not gravity. If you've never heard of this, please look at some of these resources before trying to answer this question: http://plasmascience.net/tpu/TheUniverse.html http://www.holoscience.com/ http://members.cox.net/dascott3/index.htm "The Big Ban Never Happened" by Eric Lerner There are many apparently startling results that come out of this perspective. First, it has produced cosmological predictions vastly more accurate than those of the classical model (cf. http://www.thunderbolts.info/tpod/2005/arch05/050704predictions.htm). Second, it offers explanations of phenomena still "mysterious" to modern science (e.g. the temperature of the sun's corona). However, whenever I hear scientists not of this camp comment on plasma cosmology, they just reject it out-of-hand with little more explanation than "It's just wrong." Would someone please explain why? Sorry, one link doesn't work. For a successful plasma-based prediction, look up references to "Deep Impact" for July 4th, 2005 in the archives of Thunderbolts Picture of the Day: http://www.thunderbolts.info/tpod/00archive.htm This should be the correct link: http://www.thunderbolts.info/tpod/2005/arch05/050704predictions.htm First, if you're going to tell me that plasma cosmology is objectionable "because it's wrong," don't bother. I want to know WHY it's considered wrong. Calling it "pseudoscience" doesn't get us anywhere unless you care to define what that means and why it's justifiable to call plasma cosmology pseudoscientific. Second, please don't appeal to the "You know too little to understand" argument. I have no trouble understanding Penrose's "The Road to Reality." If you think I'm missing something, please explain. Third, thanks to the third respondant for posting the Kronia video. I didn't know that had been uploaded! I've met those people and I respect them. However, some of their science is off. The whole point of relativity was to solve a problem in electromagnetism. However, this doesn't change the fact that plasma cosmology (a) predicts and (b) explains phenomena that standard cosmology apparently does not. I'd like to know why this is considered unworthy of comment.
How does quantum gravity explain cosmology events prior to “10[-43]” seconds after the start of the universe? Before answering remember - Biological information is not encoded in the laws of physics and chemistry … (and it) cannot come into existence spontaneously. … There is no known law of physics able to create information from nothing.’ To Anki Rocks -Thanks for the background on quantum physics..However your statement does nothing to answer my above question, because only an intelligence/Creator can provide the information needed prior to "10[-43]".. The biggest mystery of all is the one cited by Stephen Hawking in A Brief History of Time: Why is there something rather than nothing? More specifically, what triggered the Big Bang, and why did the universe take this particular form rather than some other form that might not have allowed our existence? Attempts to solve these mysteries often take the form of what I call ironic science—unconfirmable speculation more akin to philosophy or literature than genuine science. Another example of ironic science is string theory,but the theory comes in so many versions that it predicts virtually everything—and hence nothing at all. Critics call this the "Alice's restaurant problem," a reference to a folk song with the refrain,"You can get anything you want at Alice's restaurant! To PhysicsD..This is the correct format for my question which is asked from a science-point-of-view however because as you correctly stated "Nothing" existed prior to "10^-43". So the correct answer to ny question is "Quantum cosmology cannot explain the event prior to "10^-43" because the probability of something's coming out of nothing is incoherent. To Gengi M. Wrong! - Scientists have never observed abiogenesis (i.e. the creation of life from non-life) happening in nature, nor have they been able to create any lifeforms through controlled (i.e. manmade) experiments. Abiogenesis seems out of the realm of empirical science. Furthermore, the extreme complexity of all lifeforms seems to point in the direction of an outside Intelligence..Now your question Where did God come from - 1-Everything WHICH HAS A BEGINNING has a "cause" 2 - The Law of Thermodynamics prove beyond any doubt that the universe has a beginning 3- Therefore the universe has a "Cause". Einstein's general relativity showed that TIME is linked to matter & space. So TIME itself begun along with matter & space at the start of the universe. Since God by definition created the universe he also "Created" TIME! and is NOT limited by the time dimension HE CREATED so he has NO BEGINNING in time. Therefore he does not have or need to have a "cause"...
What mathematics should I know to study cosmology? I listened to a CalTech presentation by Kip Thorne, and he referred to a ton of strange math such as tensor calculus. I want to know what kind of math is necessary to understand technical papers about relativity, galaxy formation, and the birth and death of the universe. Thanks! When I try to read academic paper regarding cosmology, I barely get past the abstract before being overwhelmed by strange greek symbols with no accompanying explanation. What kind of math is this? What branches of mathematics are necessary to understand these papers?
Would you give me your opinion on my cosmology? Would you give me your opinion on my cosmology? Everything comes from death, suffering, and destruction, reaches its height in the radiance of goodness, and eventually ends with death, suffering, and destruction. Thanks everyone for your visit...
Can you suggest some good books to start learning physical cosmology? I'm talking beyond Hawking, here. I'd like to study mathematical physics and really understand the complex technical nuances of the theories of the structure of the universe. Where should I begin? I'm very widely-read on astronomy and have done graduate coursework in theoretical statistics, which is not the same as mechanical statistics, obviously. I was really into cosmology as a kid until my parents talked me out of it. I remember arguing with family members at dinner parties about superstring theory.
Can anyone recommend a good book, or on-line source, to bring me up to date on Cosmology? The last thing I read was A Brief History Of Time by Prof. Stephen Hawking. But that was years ago! I am particularly interested in this "dark energy" thing people are talking about! Thanks in anticipation... The idea of "dark matter" has been around for years. I am familiar with that! "Dark energy" is supposed to be responsible for the increasing rate of expansion of the universe and is a recent development! I will read Richard Dawkins book. It's not what I am looking for here, but I am sure that it is my kind of book! Thanks.
What do you think of Hindu Cosmology as per Carl Sagan? "As far as I know, India is the only ancient religious tradition on the Earth which talks about the right time scale. In the West, people have the sense that what is natural is for the universe to be a few thousand years old, and that it is billions of years is mind-reeling, and no one can understand it. The Hindu concept is very clear. Here is a great world culture which has always talked about billions of years." "The Hindu religion is the only one of the world's great faiths dedicated to the idea that the Cosmos itself undergoes an immense, indeed an infinite, number of deaths and rebirths. It is the only religion in which the time scales correspond, to those of modern scientific cosmology. Its cycles run from our ordinary day and night to a day and night of Brahma, 8.64 billion years long. Longer than the age of the Earth or the Sun and about half the time since the Big Bang. And there are much longer time scales still." ~ Carl Sagan
Do you have a PhD in Astronomy, Astrophysics or Cosmology? I know some, but very little, about this subject. I read answers that are "all over the map" or should I say "all over the cosmos" . It would be most helpful to have answers from someone who can communicate to a layman and who actually knows something. I would like to thank all of you for your excellent answers.
Any new good cosmology book for the "layman"? Are there any new entertaining (not getting into mathmatics) cosmology books for the intelligent, but mathmatically illiterate person. Last couple I read and liked are: Elegant Universe: Brian Greene Fabric of the Cosmos: Brian Greene Parallel Worlds: Michio Kaku Thanks
Evolution in Biological Sciences and Evolution in Cosmology. What is the difference? Seems to me that Biological Science describes Evolution of biological organized systems with laws and mechanisms differents from the way that Cosmology or Astronomy describes the Evolution of others physical systems, like particles, atoms, astronomic systems. Do you know which are the differences? Do you believe that the Evolution of living beings is different from the Evolution of the so called "non-livings"? Do you believe that the Universal History is shared in two blocks, one different from the other?!
Is Cosmology and its branches of science the only important profession on Earth.? I think in my perfect world, 75% of the people on Earth would be studying the origins of the Universe. Ugh, the simpletons are taking this to literally. The meat of the point is that nothing else is important, nothing. wtf, you think a doctor is more important than finding out the origins of the universe? Godamn I wish people would evolve quicker.
Cosmology- who is not overwhelmed by its study? All the work that has been done since Einstein in Cosmology is mind-blowing. How can anyone conceptualize the vast amounts of space and time and make sense out of it? I know that many cosmologists, themselves have reacted viscerally to new discoveries and have the same difficulty I have. But what keeps them on track? Is it the mathematical formulas that they develop that can keep them grounded? Or are they stumbling blindly through their work? I find cosmology and quantum physics fascinating, but I often get lost because their ideas and theories are so unfamiliar. What do you think? Bradschum, yeah! the string theory seems to answer a lot of questions, but trying to grasp the concepts of all you mention gives me a queasy stomach!
What are the cardinal points of orientation of this consumptive cosmology? R there disadvantages/benefit of tying contemporary identity to consumption? Watch online the documentary The Persuaders @ http://www.pbs.org/wgbh/pages/frontline/... DOUGLAS RUSHKOFF: It was near the end of my tour through the landscape of persuasion that I came to realize how the problem of clutter finally gets solved. Marketers find a way so deep inside each of us that it no longer feels like persuasion at all. Maybe we are in control. Once the market becomes the lens through which we choose to see the world, then there's no "us" & "them" anymore We're all persuaders STUART EWEN: The secret of it all, the secret of all persuasion, is to induce the person to persuade himself ROBBINs, compared Navajo curer’s practice of sandpainting to the Persuader practices, suggests that each creates a cultural cosomology to locate & define identity Robbins writes “contemporary sandpainters construct for us a culture in which every individual enacts the identity of consumer" the documentary is free online
An introduction to cosmology. Recommended reading? I would like to learn more about cosmology. Could someone recommend a good introductory book on the subject for the layperson, and a more advanced text to follow it up with? The reading is just for personal interest, not formal study. I've studied Stage II mathematics at university but as far as physics goes, nothing beyond highschool level. So something appropriate to that level. Thanks!
