Largest cosmic structures 'too big' for theories - space - 21 June 2011 - New Scientist - 0 views

  •  
    Space is festooned with vast "hyperclusters" of galaxies, a new cosmic map suggests. It could mean that gravity or dark energy - or perhaps something completely unknown - is behaving very strangely indeed. We know that the universe was smooth just after its birth. Measurements of the cosmic microwave background radiation (CMB), the light emitted 370,000 years after the big bang, reveal only very slight variations in density from place to place. Gravity then took hold and amplified these variations into today's galaxies and galaxy clusters, which in turn are arranged into big strings and knots called superclusters, with relatively empty voids in between. On even larger scales, though, cosmological models say that the expansion of the universe should trump the clumping effect of gravity. That means there should be very little structure on scales larger than a few hundred million light years across. But the universe, it seems, did not get the memo. Shaun Thomas of University College London (UCL), and colleagues have found aggregations of galaxies stretching for more than 3 billion light years. The hyperclusters are not very sharply defined, with only a couple of per cent variation in density from place to place, but even that density contrast is twice what theory predicts. "This is a challenging result for the standard cosmological models," says Francesco Sylos Labini of the University of Rome, Italy, who was not involved in the work.

Through The Wormhole - Is There A Creator? | Watch Free Documentary Online - 0 views

  •  
    It's perhaps the biggest, most controversial mystery in the cosmos. Did our Universe just come into being by random chance, or was it created by a God who nurtures and sustains all life? The latest science is showing that the four forces governing our universe are phenomenally finely tuned. So finely that it had led many to the conclusion that someone, or something, must have calibrated them; a belief further backed up by evidence that everything in our universe may emanate from one extraordinarily elegant and beautiful design known as the E8 Lie Group. While skeptics hold that these findings are neither conclusive nor evidence of a divine creator, some cutting edge physicists are already positing who this God is: an alien gamester who's created our world as the ultimate SIM game for his own amusement. It's an answer as compelling as it is disconcerting.

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.

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.

What Is Reality? | Watch Free Documentary Online - 0 views

  •  
    There is a strange and mysterious world that surrounds us, a world largely hidden from our senses.The quest to explain the true nature of reality is one of the great scientific detective stories.Clues have been pieced together from deep within the atom, from the event horizon of black holes, and from the far reaches of the cosmos.It may be that that we are part of a cosmic hologram, projected from the edge of the universe. Or that we exist in an infinity of parallel worlds. Your reality may never look quite the same again.

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 ยป".
  • 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!
