Gravitas: Portraits of a Universe is astrophysicist John Dubinski’s self-published DVD containing his stunning supercomputer simulations of galactic evolution set to music. Dubinski has now made the DVD disk image available free via BitTorrent for personal and educational use. You can also see online versions of the simulations at his site. From Cornell University’s arXiv e-print service:
GRAVITAS… presents a visual and musical celebration of the beauty in a dynamic universe driven by gravity. Animations from supercomputer simulations of forming galaxies, star clusters, galaxy clusters, and galaxy interactions are presented as moving portraits of cosmic evolution. Billions of years of complex gravitational choreography are presented in 9 animations – each one interpreted with an original musical composition inspired by the exquisite movements of gravity. The result is an emotive and spiritually uplifting synthesis of science and art.
