The Sibelius-Dark simulation was unveiled at the University of Durham.
REPUBLIKA.CO.ID, DURHAM — The part of the universe has been mapped into the most accurate simulations by scientists using a supercomputer. The Sibelius-Dark simulation was unveiled at the University of Durham. The map captures the Big Bang to date, and the entire evolution of the cosmos.
“It’s very interesting to see the structures we know exist around us emerge from computer calculations,” said Professor Carlos Frenk of the Institute for Computational Cosmology at the University of Durham. Sky News on Thursday (10/2/2022).
“The simulations only reveal the consequences of the laws of physics at work on dark matter and cosmic gases for the 13.7 billion years our universe has existed.”
Scientists use advanced statistical techniques so that simulations are conditioned to reproduce map of the universe specific one. At the center of the simulation is a pair of galaxies, virtual representations of the Milky Way and the Andromeda galaxy.
The new simulation is part of the Simulations Beyond the Local Universe (Sibelius) project and covers volumes up to 600 million light-years from Earth.
The map is also represented by more than 130 billion simulated particles, which require thousands of computers to work together over several weeks. It then generates more than a petabyte (1,000 terabytes) of data.
The simulations were performed on the DiRAC COSmology MAChine (Cosma), which is operated by the Institute for Computational Cosmology at Durham University. The researchers involved came from around the world, including Durham University, and were led by the University of Helsinki.
The findings are published on arXiv.org and as a preprint in the journal Monthly Notices Royal Astronomical Society.
