超级计算机模拟证实了宇宙形成模型

Astronomers at  UC Santa Cruz have set  a new benchmark for cosmological research for decades to come maybe, after successfully simulating the forming of distant galaxies, like our very own Milky Way, under the mysterious forces of dark matter and dark energy。

Named Bolshoi –; for the Russian word meaning “;grand”; or “;great”; –; the simulation’;s results are on par with what astrophysicists have theorized for years, confirming the current models which try to explain how the “;Big Bang”; sparked the origin of the subatomic particles and galaxies that populate our expanding Universe。 Thi****traordinary feat was reached after more than four years of hard work and with the help of the invaluable Pleiades supercomputer at NASA‘;s Ames Research Center in Mountain View –; one of the most powerful computing unit in the world。

“;In one sense, you might think the initial results are a little boring, because they basically show that our standard cosmological model works,”; physics Professor Joel Primack said in a university release Thursday。 “;What’;****citing is that we now have this highly accurate simulation that will provide the basis for lots of important new studies in the months and years to come。”;

Anatoly Klypin, an astronomer at New Mexico State University, wrote the computer code that produced it, Primack said。 He went on to say, the simulation will provide astronomers around the world with new guides for observing and describing the most distant galaxies that telescopes can see。

The simulation is based  on a “;map”; of the early universe that was created nearly 10 years ago by a satellite called the Wilkinson Microwave Anisotropy Probe, or Wmap。 The afformentioned probe captured a faint microwave echoed by the long forgoten Big Bang, now calculated to have occurred 13。7 billion years ago, and has since then provided invaluable data for various models, simulations or Universe maps
