NASA is tackling questions like these inside supercomputers. Here, billions of calculations per second recreate the universe mathematically.

Supercomputers can process observations into a motion picture. Or, they can solve equations that describe realities seen and unseen.

To understand and predict nature through computation, NASA started the Earth and Space Sciences (ESS) Project, which has become the Computational Technologies Project under the Earth-Sun System Technology Office.
