A group of theoretic astrophysicist based in Germany has produced the large and most detailed example of the distribution of visible matter in the universe . In doing so , they launch the most sophisticated simulation of the universe ever produced .
In scientific discipline , the most successful theory are those that can explicate what we have maintain as well as predicting unexampled and interesting phenomena . In astronomy , this is not easily accomplish . We only have one universe to count at , and both testing and predictions are affected by this limit . This is why astronomers often use simulations to compare current hypotheses to what we in reality observe in the universe .
The Magneticum Pathfinder pretence is the latest of these example and represents a huge step forward , create a sophisticated replica of the creation made of 180 billion element . The full simulation bring forth 320 Terabytes of scientific data .
The simulation uses the three principal ingredient of the cosmos : seeable subject , drab affair and dark energy . moody matter is a eccentric of matter that can not be control ; it does n’t emit or take over light , though it has mass and so interacts with gravitational attraction . It is responsible for over one - fourth part of the full aggregate - energy mental object of the universe . Dark Energy , sometimes call vacuum energy , is responsible for for the accelerated enlargement of the universe .
Using these ingredients and elaborated description of many different physical processes , the simulation allows for the closest compare between observations and theoretical models . The simulation was able-bodied to equate the distribution of seeable matter in the existence today , and it also discovered that grim thing halos – thought to envelop galaxies – gyrate around importantly quicker around galax than cold gun does .
technical advancement in uranology , the availability of hundreds of Earth - found and space telescopes covering all wavelength , and citizen scientist facilitate with theclassification of galaxieshas generated a wealth of observational cognition . The Magneticum Pathfinder pretence , being so detailed , is the pure instrument to liken the observations with the latest theory : It will let for pinch to the models and maybe forecast some yet to be witnessed phenomena .
" Astronomical surveys from place scope like Planck or Hubble celebrate a large section of the seeable population while advanced simulations so far could only model very small part of the universe of discourse , making a direct comparison virtually unacceptable , " said Klaus Dolag , leader of the project , in astatement . " Thus , Magneticum Pathfinder marks the beginning of a Modern era in figurer - based cosmology . "
The data create is now available for concerned researchers worldwide , and more entropy is uncommitted at theMagneticum Pathfinder website .
