Here Is How The Universe Evolved In The Last 13 Billion Years [Video]

With the help of massive computer simulation, researchers have created a model of universe's evolution with new accuracy in some of the important measures. The model spans 13 billion years of cosmic evolution.

The model has generated a new degree of fidelity for certain observed features of the universe i.e. the frequency at which galaxies of different shapes occur in universe.

"With this model, we are able to get agreement with observational data on small scales and large scales," said Mark Vogelsberger, an assistant professor of physics at MIT and first author of a new paper, in the press release.

The simulation models 41,416 galaxies while closely matching the rate at which certain type of galaxies develop across the universe as a whole.

"Some galaxies are more elliptical and some are more like the Milky Way, [spiral] disc-type galaxies," Vogelsberger explained. "There is a certain ratio in the universe. We get the ratio right. That was not achieved before."

The newly developed model represents a cube-shaped piece of universe with each side being 350 million light-years long. The model still manages to produce features that are relatively on a smaller scale - 1,000 light years.

The model also accurately describes the richness of neutral hydrogen as a function of the stellar mass of galaxies.

"You can take a virtual Hubble Space Telescope and look through the simulation, as it were," Vogelsberger said."The model is more successful than we anticipated."

The study has been published in the journal Nature.
