Researchers compute trillion particle “dark sky” simulation

Michael Byrne, for Motherboard:

Particle-based simulations, in which large-scale cosmic features like gas clouds and stars (and the interactions between them) are represented by simple points, are a crucial tool for both connecting the realm of particle physics and cosmology and for studying the structural development of the universe since the Big Bang.

As can be seen in the composite image, the universe is composed of galaxies, filaments or tendrils connecting galaxies, and vast voids in between galaxies. The result is surprisingly uniform across space.

An impressive feat. But, if simulating a slice of universe requires so much computational power, just imagine how much computing power is required to simulate our universe. Are we tapping into the computational constant?
