Another fascinating example of computational science, The Cosmic Dawn Project - how the universe evolved after Big Bang

 An amazing animation coming from a supercomputer simulation of the evolution of the universe following the Big Bang has been published. This movie shows how it took tens of millions of years for the first gas atoms and molecules (almost entirely hydrogen) to begin to come together under gravity to form the first stars. What this new simulation does for the first time is include the interaction between radiation from the Big Bang and the first stars and matter (gas clouds). Filaments of gas formed in a web-like pattern, which are the white strands that develop in the movie. It is along these massive strands where more stars and eventually the first galaxies formed. We see web-like patterns of matter forming a superstructure to the universe to this day! Very cool! This is part of the Cosmic Dawn Project, which attempts to understand the birth and evolution of the universe.
