HS-Digital Video Library pdboyer Sun, 07 Nov 2010 00:18:46 GMT http://science.nasa.gov/astrophysics/focus-areas/what-is-dark-energy/ Eventually theorists came up with three sorts of explanations. Maybe it was a result of a long-discarded version of Einstein's theory of gravity, one that contained what was called a "cosmological constant." Maybe there was some strange kind of energy-fluid that filled space. Maybe there is something wrong with Einstein's theory of gravity and a new theory could include some kind of field that creates this cosmic acceleration. Theorists still don't know what the correct explanation is, but they have given the solution a name. It is called dark energy. pdboyer Sat, 06 Nov 2010 19:44:07 GMT http://science.nasa.gov/astrophysics/big-questions/when-and-how-did-the-elements-of-life-in-the-universe-arise/ Following the Big Bang and the gradual cooling of the Universe, the primary constituents of the cosmos were the elements hydrogen and helium. Even today, these two elements make up 98% of the visible matter in the Universe.  Nevertheless, our world and everything it contains—even life itself—is possible only because of the existence of heavier elements such as carbon, nitrogen, oxygen, silicon, iron, and many, many others. How long did it take the first generations of stars to seed our Universe with the heavy elements we see on Earth today?  When in the history of the Universe was there a sufficient supply of heavy elements to allow the formation of prebiotic molecules and terrestrial-like planets pdboyer Sat, 06 Nov 2010 19:38:23 GMT http://science.nasa.gov/astrophysics/big-questions/how-do-planets-stars-galaxies-and-cosmic-structure-come-into-being/ How do planets, stars, galaxies and cosmic structure come into being? In order to understand how the Universe has changed from its initial simple state following the Big Bang (only cooling elementary particles like protons and electrons) into the magnificent Universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed. pdboyer Sat, 06 Nov 2010 19:37:04 GMT http://science.nasa.gov/big-questions/ Big Questions NASA has defined a set of space and Earth Science questions that can best be addressed using the Agency’s unique capabilities.  NASA works with the broader scientific community, considers national initiatives, and the results of decade-long surveys by the National Research Council in defining these questions. See also the Science Strategy section for more information about how NASA Science is pursuing these questions. pdboyer Sat, 06 Nov 2010 19:33:35 GMT https://www.amazon.com/Decoding-Reality-Universe-Information-Landmark/dp/0198815433/ref=dp_ob_title_bk Decoding Reality: The Universe as Quantum Information (9780199237692): Vlatko Vedral: Books Miscellaneous > Books > Want List mcswell Sat, 24 Jul 2010 22:36:30 GMT http://cas.sdss.org/dr5/en/proj/teachers/advanced/hubble/specifics.asp Teacher's Guide to Specific Sections Introduction Let students read through the Introduction on their own. Ask them why the discovery that the universe was expanding was so unexpected. Point out that its discovery required three separate threads to come together: Einstein's General Relativity, Slipher's measurements of redshifts, and the building of the new 100" telescope on Mount Wilson. Ask them how the three other lines of evidence support the big bang theory. Get them thinking about how different lines of evidence add up to support a scientific theory. Ask: what makes a good theory? pdboyer Sat, 24 Apr 2010 16:02:46 GMT http://www.vega.org.uk/video/subseries/8 Chosen by the New Scientist - best on-line videos 2007. A set of four priceless archival science video recordings from the University of Auckland (New Zealand) of the outstanding Nobel prize-winning physicist Richard Feynman - arguably the greatest science lecturer ever. Although the recording is of modest technical quality the exceptional personal style and unique delivery shine through.

So begins The Known Universe, a new film produced by the American Museum of Natural History that is part of a new exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in New York City.The structure of The Known Universe is based on precise, scientifically-accurate observations and research ycc2106 Tue, 29 Dec 2009 22:30:23 GMT
