In this view of the mantle below the Pacific, warm colors denote slower than average seismic wavespeeds. Cold colors denote faster than average seismic wavespeeds associated with subduction zones.  Image courtesy of Ebru Bozdag, University of Nice, and David Pugmire, Oak Ridge National Laboratory. The ground beneath our feet seems still, yet,...

Scientists at Princeton University are composing the complex codes designed to instruct a new class of powerful computers that will allow researchers to tackle problems that were previously too difficult to solve. These supercomputers, operating at a speed called the “exascale,” will produce realistic simulations of dazzlingly complex phenomena in...

Postdoctoral researchers Shravan Hanasoge of Princeton's Department of Geosciencesand Michael Kesden of NYU's Center for Cosmology and Particle Physics simulated the visible result of a primordial black hole passing through a star. Theoretical remnants of the Big Bang, primordial black holes possess the properties of dark matter and are one of...
