Universe is Not Expanding After All, Scientists Say New evidence, based on detailed measurements of the size and brightness of hundreds of galaxies, indicates that the Universe is not expanding after all, says a team of astrophysicists led by Eric Lerner from Lawrenceville Plasma Physics. This image shows a star forming region in a nearby galaxy known as the Large Magellanic Cloud. Image credit: ESA / Hubble. In their study, the scientists tested one of the striking predictions of the Big Bang theory – that ordinary geometry does not work at great distances. In the space around us, on Earth, in the Solar System and our Milky Way Galaxy, as similar objects get farther away, they look fainter and smaller. In contrast, the Big Bang theory tells us that in an expanding Universe objects actually should appear fainter but bigger. So in an expanding Universe the most distant galaxies should have hundreds of times dimmer surface brightness than similar nearby galaxies, making them actually undetectable with present-day telescopes.

String Theory and the Scientific Method | Not Even Wrong There’s a new philosophy of science book out, Richard Dawid’s String Theory and the Scientific Method (available online here if your institution is paying Cambridge University Press appropriately or if you have a credit card). It comes with endorsements from string theorists David Gross and John Schwarz, with Schwarz writing: Richard Dawid argues that string theory plays a novel role in the scientific process that has been neglected by philosophers of science. I believe that this book is a valuable contribution to the philosophy of science, which should interest practicing scientists as well as those who are more interested in the methodology of science. Dawid is a particle theorist turned philosopher, and as you might guess from the endorsement, he approaches string theory from an enthusiast’s point of view. This book has been on my mind ever since I left physics and turned to philosophy in the year 2000. In Dawid’s description, string theorists are still partying like it’s 1999:

untitled The Universe Magnified This is one of the most beautiful infographics we've ever seen: a high resolution view of different levels of the universe. Our favorite parts are the jaw-dropping nebulae and then the point where you see the size of Pluto compared to Texas. Puts things into perspective. Try it out in full-screen mode: Copyright 2012. Embed this infographic on your site! <iframe width="600" height="388" scrolling="no" src=" frameborder="0" allowfullscreen></iframe><br />Copyright 2012. To get started with the infographic, click on one of the nine entry point images. The slider at the bottom of the screen lets you move around from bigger to smaller and smaller to bigger. And in between you see every day objects like animals and buildings and planets and stars. Have fun with this!

The best wideband filters for the production of colour images are F435W, F439W, F450W, F555W, F606W, F675W, F702W, F791W, and F814W. Narrowband filters used include F437N, F502N, F656N, F658N, and F673N. 1Locate the fourth image in the result for the search of NGC 604 above and you will find the file name "hst_05237_02_wfpc2_f814w_wf" below it. For this guide, download hst_05237_02_wfpc2_f814w_wf, hst_05237_02_wfpc2_f555w_wf, and hst_05237_02_wfpc2_f336w_wf.

Dodwell Manuscript Ancient, mediaeval, and modern observations of the obliquity of the Ecliptic, measuring the inclination of the earth's axis, in ancient times and up to the present by George F. Dodwell B.A., FRAS* *B.A. is Bachelor of Arts -- his degree was in mathematics (which was an art then). FRAS is Fellow of the Royal Astronomical Society. © the Dodwell Family - J D Dodwell, PGE Dodwell, David Dodwell and their descendants -- sections may be quoted or printed with full reference made to the original document on this website, with the request they not be taken out of context. Note from the Setterfields George Dodwell was the government astronomer for South Australia. A friend of his offered to take the material and have it published under the auspices of a university in the United States. Since we have the original manuscripts ourselves, every word has been checked and every punctuation mark, for accuracy. All emphases are in the original. So here, finally, is Dodwell’s work.

Russian billionaire, Hawking announce $100 million search for ET Green Bank Telescope (credit: Geremia/Wikimedia Commons) Russian billionaire Yuri Milner, Stephen Hawking, Martin Rees, Frank Drake and others announced at The Royal Society today $100 million funding for Breakthrough Listen — the “most powerful, comprehensive, and intensive scientific search ever undertaken for signs of intelligent life beyond Earth.” They also announced $1 million prize funding for Breakthrough Message, a competition to generate messages representing humanity and planet Earth. “It’s time to commit to finding the answer to search for life beyond Earth,” said Hawking. “We are live, we are intelligent, we must know … if we are alone in the dark.” The search will be done at two of the largest radio telescopes, the 100 Meter Robert C. More sensitive, faster, wider spectrum, more sky coverage The Breakthrough Listen initiative will be 50 times more sensitive than previous programs dedicated to SETI research, the scientists say.

THIS IS PROOF THAT WE ARE COMPLETELY INSIGNIFICANT. OR... ARE WE JUST THAT SPECIAL? | Guys The Road During your day-to-day life, you can get pretty wrapped up in yourself. You can forget to feed your cats or neglect to call your mother on her birthday. We think our lives are just about us. Well, I suddenly feel very very tiny. Source:
