Computing the Cosmos

One of the biggest computer simulations ever run is illuminating the deepest mysteries of the universe

13 min read

If cosmologists were to make a movie of the universe's entire history, the show would start, of course, withthe scorching blast of the Big Bang. The universe--absolutelyevery bit of mass we can detect or even infer today--wouldexpand at unfathomable speeds, going from smaller thana proton to larger than a galaxy in the blink of aneye. As the expansion continued, the universe wouldcool down, and by the time the opening credits of themovie finished scrolling, a superhot soup of elementaryparticles would fill the whole cosmos, ready to cookthe first protons and neutrons.But what would happennext?

The fact is, cosmologists are still working out the restof the plot--what exactly took place during the morethan 13 billion years since that primeval blast. [Forthis article, in keeping with the current trend in internationalscientific publishing, IEEE Spectrum uses thewords "billion" to mean 10 9 and "trillion" tomean 1012.] A particular piece of the storythat has kept researchers scratching their heads is howgalaxies formed and evolved. How did that amorphous particlesoup transform itself into billions and billions of galaxiesof breathtakingly different shapes and sizes? Why didthese galaxies gather together in clusters, and clustersof clusters, embedded along unimaginably enormous structuresof matter shaped like bubbles, filaments, and sheets?

This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore.

Deep learning is a critical computing approach that is pushing the boundaries of technology – crunching immense amounts of data and uncovering subtle patterns that humans could never discern on their own. But for optimal performance, deep learning algorithms need to be supported with the right software compiler and hardware combinations. In particular, reconfigurable processors, which allow for flexible use of hardware resources for computing as needed, are key.

For more than 25 years, Rory Cooper has been developing technology to improve the lives of people with disabilities.

Cooper began his work after a spinal cord injury in 1980 left him paralyzed from the waist down. First he modified the back brace he was required to wear. He then turned to building a better wheelchair and came up with an electric-powered version that helped its user stand up. He eventually discovered biomedical engineering and was inspired to focus his career on developing assistive technology. His inventions have helped countless wheelchair users get around with more ease and comfort.
