Supercomputer Simulation Animates Evolution of the Universe


Radiation (blue) emanates from dense filaments of stars and galaxies (white) in this snapshot from a new simulation of the early universe.

CoDaIII is the first simulation to fully account for the complicated interaction between radiation and the flow of matter in the universe, says astronomer Paul Shapiro of the University of Texas at Austin.

An international team of researchers has engineered the most accurate supercomputer animation of the cosmos' early evolution to date.

The simulation represents the third version of the Cosmic Dawn Project (CoDaIII), which the University of Texas at Austin's Paul Shapiro described as the first model to fully encompass the interaction between radiation and the flow of matter in the universe.

CoDaIII spans the period from about 10 million years after the Big Bang through the next several billion years, as matter composing the modern cosmos diffused.

Shapiro said the animation depicts how the early universe's structure is "imprinted on the galaxies today, which remember their youth, or their birth, or their ancestors from the epoch of reionization."
