Physicists propose mechanism that explains the origins of both dark matter and 'normal'... - 1 views

  •  
    (PhysOrg.com) -- Through precise cosmological measurements, scientists know that about 4.6% of the energy of the Universe is made of baryonic matter (normal atoms), about 23% is made of dark matter, and the remaining 72% or so is dark energy. Scientists also know that almost all the baryonic matter in the observable Universe is matter (with a positive baryon charge) rather than antimatter (with a negative baryon charge). But exactly why this matter and energy came to be this way is still an open question. In a recent study, physicists have proposed a new mechanism that can generate both the baryon asymmetry and the dark matter density of the Universe simultaneously.

Getting Started with Firefox extension - Diigo help - 0 views

  •  Feature Highlight: Highlights Diigo saves the day with "highlights". Highlights let you select the important snippets on a page and store them in your library with the page's bookmark. Let's try it. Just open a page, maybe one of your old-school bookmarks or one of your new cat bookmarks, and find the information on that page you actually care about. Select that important text. Got it? Okay, now put your hemet on, 'cause this might blow your mind! Click the highlight icon on the Diigo toolbar. It's the one with the "T" on a page with a yellow highlighter. You will notice that the selected text gets a yellow background. This means that the text has been saved in your library, and as long as you have the Diigo add-on the text will be highlighted on the page! How's that for easy?   Now you've highlighted the text. It will appear in your library within the bookmark for the page it is on. Go to your library and you can see how it works. If you're not sure how to get to your library, just click the second icon on the toolbar (Diigo icon to the left of the search bar) and then select "My Library »".
  • Sticky Notes on the Web What? I can put a sticky note on a web page? How? Oh, that's right! Diigo. Just right-click anywhere on the page and choose to "add a floating sticky note". Type up your note and choose "Post", then move the note anywhere on the page. You have to type a note first, before you move it where you want, otherwise there's nothing to move!

    The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum,  is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.     Data: Digital Universe, American Museum of Natural History  http://www.haydenplanetarium.org/universe/    Visualization Software:  Uniview by SCISS    Director: Carter Emmart  Curator: Ben R.

Fermilab is Building a 'Holometer' to Determine Once and For All Whether Reality Is Jus... - 0 views

  •  
    Researchers at Fermilab are building a "holometer" so they can disprove everything you thought you knew about the universe. More specifically, they are trying to either prove or disprove the somewhat mind-bending notion that the third dimension doesn't exist at all, and that the 3-D universe we think we live in is nothing more than a hologram. To do so, they are building the most precise clock ever created.

Dark matter could transfer energy in the Sun - 0 views

  •  
    ScienceDaily (Dec. 3, 2010) - Researchers from the Institute for Corpuscular Physics (IFIC) and other European groups have studied the effects of the presence of dark matter in the Sun. According to their calculations, low mass dark matter particles could be transferring energy from the core to the external parts of the Sun, which would affect the quantity of neutrinos that reach Earth.
