Description: Dated but nascent. The simulation is butters. Peep. Worldpeace, Ben *** The cold dark matter model has become the leading theoretical paradigm for the formation of structure in the Universe. Together with the theory of cosmic inflation, this model makes a clear prediction for the initial conditions for structure formation and predicts that structures grow hierarchically through gravitational instability. Testing this model requires that the precise measurements delivered by galaxy surveys can be compared to robust and equally precise theoretical calculations. Here we present a novel framework for the quantitative physical interpretation of such surveys. This combines the largest simulation of the growth of dark matter structure ever carried out with new techniques for following the formation and evolution of the visible components. We show that baryon-induced features in the initial conditions of the Universe are reflected in distorted form in the low-redshift galaxy distribution, an effect that can be used to constrain the nature of dark energy with next generation surveys. --- A 3-dimensional visualization of the Millennium Simulation. The movie shows a journey through the simulated universe. On the way, we visit a rich cluster of galaxies and fly around it. During the two minutes of the movie, we travel a distance for which light would need more than 2.4 billion years.

saltystuff ::: Favorites Each dot is a super cluster of galaxys. They spand across the cosmos in large bands called "filaments" Leaving empty "voids" in between. I think the filaments follow along the chain of dark matter. 07-06-18 22:02:55 __________________________________________________

blackfrogger007 ::: Favorites This is pretty cool -- but even with the text on the side, I'm confused as to what I'm looking at; I'm not in the hard/physical sciences.. =/ 07-03-31 12:25:23 __________________________________________________
willywonka4340 ::: Favorites Like saltystuff said, these are strands of galaxies culster together in a certain chain pattern. Begs this question: why AREN'T galaxies evenly distributed throughout the universe instead, as astronomers/cosmologists once thought? Also, this clip reminds me of how DNA strands look like in a cell's nucleus. Macro to Micro. ;) 07-06-21 04:01:00 __________________________________________________
