Millennium Simulation: The largest model of our Universe

submitted by Majortomyorke

1 decade 7 years 2 months 3 weeks ago

Millennium Simulation:
The Virgo consortium, an international group of astrophysicists from the UK, Germany, Japan, Canada and the USA has today (June 2nd) released first results from the largest and most realistic simulation ever of the growth of cosmic structure and the formation of galaxies and quasars. In a paper published in Nature, the Virgo Consortium shows how comparing such simulated data to large observational surveys can reveal the physical processes underlying the build-up of real galaxies and black holes.

PLEASE READ: A parsec (symbol pc) is a unit of length used in astronomy. The length of the parsec is based on the method of trigonometric parallax, one of the oldest methods for measuring the distances to stars.

The name parsec stands for "parallax of one second of arc", and one parsec is defined to be the distance from the Earth to a star that has a parallax of 1 arcsecond. The actual length of a parsec is approximately 3.262 light-years.

I miss you Carl Sagan...

And yet it doesnt match up to Almighty God making a shrubbery burn in an old myth... Go into your churches and be impressed at your own peril, meanwhile I will stand in awe in the cathedral of life, founded by a cosmic anomaly and built by evolution.

Upvote for Pink Floyd, and sheer coolness.

Upvote for the Floyd as well. I'm curious though...at about 3:10, what are we looking at? Would that be the Virgo Supercluster? Or just the Local Group? I'm gonna go with the Supercluster just because of the sheer number of galaxies represented.
