Scientists have produced the largest and most accurate virtual representation of the Universe to date. An international team of researchers, led by the University of Helsinki, and including members from Durham University in the UK, used supercomputer simulations to recreate the entire evolution of the cosmos, from the Big Bang to the present. The findings are published in the Monthly Notices of the Royal Astronomical Society.
The simulation, named SIBELIUS-DARK, is part of the “Simulations Beyond the Local Universe” (SIBELIUS) project, and is the largest and most comprehensive ‘constrained realization’ simulation to date. The team meticulously compared the virtual Universe to a series of observational surveys to find the correct locations and properties for the virtual analogies of the…
