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.

Is the universe REALLY infinite ? - 0 views

How did the universe come into being? As it evolved, how it will continue in the future with it? And there are really aliens - or are we alone in the vastness of the universe? These are just som...
