A Simulation of the Whole Universe

Jun 2, 2005 - An international team of researchers have developed a computer program that simulates the growth and expansion of the Universe after the Big Bang, including the formation of galaxies, clusters and quasars.

The "Millennium Simulation" used 10 billion virtual particles of matter, and traced their movements in a 2 billion light-year cube of space as the Universe evolved. This simulated area contained 20 million virtual galaxies, and accounted for dark energy expanding the Universe, cold dark matter, and regular matter.

I think it will help us better understand motion, but it's kinda like an ant figuring out the Earth from just their local knowledge,

In another thread you said that all astronomy is guesswork. I was about to gripe at you about that, but then decided to bite my tongue. Now you post this to prove your point.

Heh heh... ;D

No, not all is guesswork, but a a large part is. Cosmology is largely theroretical, astrobiology has no specimens and we are still figuring out our place in space.

But fact has to begin somewhere and this is just as good a place to start from.
