First Full Observable-Universe Simulation 95

First time accepted submitter slashmatteo writes "The goal of the DEUS project (Dark Energy Universe Simulation) is to investigate the imprints of dark energy on cosmic structure formation through high-performance numerical simulations. In order to do so, the project has conducted a simulation of the structuring of the entire observable universe, from the Big Bang to the present day. Thanks to the Curie super-computer, the simulation has made it possible to follow the evolution of 550 billion particles. Two other complementary runs are scheduled by the end of May. More details in the press release."

    I didn't RTFA, but DEUS sounds like the perfect name for this project.

    550 billion particles to simulate the observable universe means just over three particles per galaxy. I don't know exactly what they're doing but it doesn't sound like much of a simulation..?

    That really depends on what you are trying to achieve. If you are not interested in the interactions going on inside each galaxy, but rather the interactions between galaxies themselves as well as things like filaments and clusters and or superclusters, this is more than enough particles to use. In fact, if each particle is assumed to be a galaxy, then the surplus may well have been introduced to see failed galaxies or to find where initial seeds may not have turned into fully fledged galaxies. They may also account for a small portion of the vast numbers of dwarf galaxies to see how these interact with larger objects.

With your bare hands?!?
