Bolshoi Simulation of the Universe [720p]

The Bolshoi simulation is the most accurate cosmological simulation of the evolution of the large-scale structure of the universe yet made ("bolshoi" is the Russian word for "great" or "grand"). The first two of a series of research papers describing Bolshoi and its implications have been accepted for publication in the Astrophysical Journal. The first data release of Bolshoi outputs, including output from Bolshoi and also the BigBolshoi or MultiDark simulation of a volume 64 times bigger than Bolshoi, has just been made publicly available to the world's astronomers and astrophysicists.

The starting point for Bolshoi was the best ground- and space-based observations, including NASA's long-running and highly successful WMAP Explorer mission that has been mapping the light of the Big Bang in the entire sky. One of the world's fastest supercomputers then calculated the evolution of a typical region of the universe a billion light years across. The Bolshoi simulation took 6 million cpu hours to run on the Pleiades supercomputer—recently ranked as seventh fastest of the world's top 500 supercomputers—at NASA Ames Research Center.

This visualization of dark matter is 1/1000 of the gigantic Bolshoi cosmological simulation, zooming in on a region centered on the dark matter halo of a very large cluster of galaxies.

I need an interactive version of this, where I can zoom in & out, select a specific point in the simulation and be provided with information.

And a desktop screensaver.

@MondrosenPrime - there are dozens of movies from this simulation available -- click the link I provided in the description. However, you won't be able to do a realtime zoom/exploration -- these animations took quite a long time to render. I'm sure you can create your own screensaver by stitching together several of the movies via a number of programs you can find online.

wow cool... looks so real..

@djxatlanta I think it need as much time to render one image with my computer as the creation of the universe and the galaxies... Maybe the universe has been created with a computer similar to mine :D

@LordEnder88 - current cosmological models suggest that space itself went a rapid expansion shortly after the universe's expansion, and this rapid expansion was indeed faster than the speed of light. Because of this faster-than-light expansion, there is a light-horizon beyond which we cannot see. Due to the presence of dark matter in a relatively small universe, the expansion rate slowed, and then began accelerating again (as it is now) due to dark energy.

@MondrosenPrime download WWT telescope from microsoft. it does exactly what you describe.

[LordEnder88]

@Doomlord52 "expansion of the universe being faster than the speed of light" do you have a reference for this? AFAIK the speed of light is the fastest that anything can travel, if it was going faster than light it would be moving faster than space/time can propagate.

[zingy1914]

@Doomlord52 yes the expansion of the universe was faster than light, but that does not affect the time it takes to reach us as light cannot exceed its own speed. so in that manner we can only see as far as 14 billion light years in all directions, which i think you are getting confused at what we see galaxies 14 billion light years away as it was 14 billion years ago, but we would see it even further today if light was traveled faster or was instantaneous.

[Doomlord52]

@zingy1914 Actually we can observe about 46 billion light years away. Due to the early expansion of the universe being faster than the speed of light, things are much farther away from us that is possible if they only traveled at the speed of light.

Whats interesting is there's likely much, much more out beyond what we can see.

sound! =3

get it? aha sound... ooooh man...

*suicide*

[muziqaz]

@MondrosenPrime Add couple of supercomputers at that as well to simulate that for you ;)

[zingy1914]

That is extraordinary.

And to think that is only 14 billion light years in diameter, where as the size of the universe could be on an even bigger scale as we are limited to to viewing it as fast as light can travel

[crzer07]

It looks like a supercluster of galaxies.

@DR000 also print screen cap, frame it and show to your grandkids

іпать, яке тупориле відео.... стільки воні, а нема на шо дивитись

[iLikeNarwhals]

@Grognax, it's an interpretation of the *visible* universe.

[LEFEVRE53]

comparez cet univers avec l humanite ?

[dfhoho]

Amazing !
