    Basic guidelines:
    • You read an article on astronomy, exobiology, or cosmology in a lay science site or a lay science magazine that puzzles you? Ask away! Please provide a link if at all possible.
      Notable exceptions: You read something about Planet Niburu, Planet X, or the year 2012? Please don't ask. That stuff is not even pseudoscience.

    • You want to know more about NASA or ESA or one of the other space agencies? Ask away.
      Notable exception: We really did send people to the moon 40 years ago, no ifs ands or buts.

    • You found some ultra-cool astronomy photo you would like to share? Post it. A picture is worth a thousand words.
      Notable exception: Some pictures are worth a million words, easily. Please do not post *huge* images using the [ img ] tags capability. Instead, make a compressed version of the image. Post the compressed image as an [ img ] tag and post a link to the full-sized image as a [ url ] tag. How to make a compressed image? One way to do that is to go to, paste in the URL to the oversized image, select "Message Board (640x480)" from the resize menu, and click the Upload button. Presto chango, you have a compressed version of the big picture suitable for embedding.

    • You want to discuss theoretical aspects of astronomy, exobiology, or cosmology? Discuss away! Several members at are knowledgeable in various aspects of the underlying theories.
      Notable exception: You *know* with a certainty that basic aspects of special relativity, general relativity, or the age of the universe are wrong? The answer to the ultimate question is not 42? You have your own pet theory of the origin of the universe? The appropriate venue for such discussions is the pseudoscience sub forum, not here.

    In addition to the above,
    • Stay on topic. Off-topic posts will be moved or removed.
    • Try to make your writing clear, concise, and readable. I'm not expecting perfect composition, but please do try.
    • Avoid overly contrived writing styles such as waxing poetic, writing in multiple colors, and writing in multiple fonts. Doing so tends to detract from rather than add to what you wrote.
    • Give proper attribution when you copy text from some other source. NO PLAGIARISM. Give a url reference if possible. Do not cut-and-paste the whole 10 page article. Much better is to give a short synopsis and a reference for further reading.

    People, I need your help and advice

    Please Register or Log in to view the hidden image!

    Recently I have developed one idea regarding removing the space debris by means of Space Elevator and I would like to publish it somewhere

    Could you indicate me the relevant journals that publish some new ideas about space activities/technologies (I do not seek for astronomical journals, my paper is not about “pure” astronomy)? My paper actually is the idea only, without some special engineering calculations and I would like to introduce it to wide public

    Cosmic Cycles of Hindu Cosmology: Scientific Underpinnings and Implications

    More than two thousand years ago Hindus unravelled some of the mysteries of the Cosmos that modern science is just discovering - that is the conclusion of a peer-reviewed scientific paper entitled "Cosmic Cycles of Hindu Cosmology: Scientific Underpinnings and Implications" that is in press in the Journal of Cosmology.

    The author, Dr. Aggarwal, shows that ancient Hindu Texts such as the Vishnu Purana predict with amazing exactitude three cardinal events covering some 18 billion years of history and future of the universe. First, the timing of the birth of the universe deduced from the Texts is almost identical to the age (13.7 billion years) inferred from scientific data. Second, the Texts indicate that planets formed within hundreds of millions and not billions of years after the dawn of the universe - a finding supported by recent observations of NASA's Hubble Space Telescope and a claim that would have been considered heresy only a decade ago. Third, the Texts predict the demise of the Earth in the next 4.2 billion years and describe in remarkable details the nature and sequence of events leading to its total incineration that are strikingly similar to those predicted by the latest scientific models of Sun's evolution and its effect on planet Earth.

    Dr. Aggarwal concludes that these concurrences leave little doubt that ancient Hindus unravelled some of the mysteries of the universe. The question is how? The question is of profound importance in understanding how knowledge may be acquired by means other than scientific observations and analytical deductions. Of equal importance are the mind-boggling implications of the cyclic nature of the cosmic processes deciphered from the Hindu Texts. The results imply that our Solar system has a life span of about 8.64 billion years and the capacity to essentially replicate itself; that the current Solar system is a successor to a primeval, now defunct, solar system that formed soon after the birth of the universe; and that humans may have previously existed on a now defunct earth-like planet some 8.7 billion years ago. In addition, the findings of this paper support the theory that the universe is cyclic in nature, that time is eternal without a beginning, and that the universe did not emerge from nothing as presumed to be the case in the Big Bang theory, but unfolded spontaneously from a limitless pre-existing dark matter that produced the primordial elements and radiation of the current universe.

    Dr. Aggarwal is a retired Geophysicist who obtained his doctorate from and served on the reaseach faculty of Lamont-Doherty Earth Observatory of Columbia Universty, New York, His work as an observational seismologist has been published in such prestigious journals as Nature and Science and he is the first person to have successfully predicted an earthquake using scientific methods (e.g Time, August 27, 1973). The current paper is in press in the Journal of Cosmology and can be accessed online.
