Artificial Universe Similar to Ours Built with Supercomputer
Building a universe from scratch that brims with galaxies resembling those around us is now possible on supercomputers for the first time, researchers say.
Our galaxy, the Milky Way, is a spiral galaxy with a broad disk and outstretched arms, as are many in our cosmic neighborhood, such as Andromeda, the Pinwheel and the Whirlpool galaxies. Spiral galaxies are common, but past computer models that aimed to accurately simulate the birth and evolution of the universe over billions of years had trouble creating them. Instead, they often generated lots of blobby galaxies clumped into balls.
New computer simulations can now recreate the kind of galactic communities seen in our universe, starting with the observed afterglow of the Big Bang and evolving forward in time. Harvard’s Odyssey supercomputer allowed simulations that compressed nearly 14 billion years into only a few months.
“We’ve created the full variety of galaxies we see in the local universe,” said study author Mark Vogelsberger at the Harvard-Smithsonian Center for Astrophysics.
And so now, computers can “imagine” macroscopic universes with scientific accuracy. I imagine they’ll be able to add our level and microscopic levels still in another 2 years. Then a computer’s imagination may just be as on part as a human’s…but accurate as well.
