The niverse Is Not a Simulation, but We Can Now Simulate It
In the early 2000s, a small community of coder-cosmologists set out to simulate the 14-billion-year history of the universe on a supercomputer.
From ACM News
Evidence Found for a New Fundamental Particle
Physicists are both thrilled and baffled by a new report from a neutrino experiment at Fermi National Accelerator Laboratory near Chicago.
From ACM News
A New World's Extraordinary Orbit Points to Planet Nine
In early 2016, two planetary scientists declared that a ghost planet is hiding in the depths of the solar system, well beyond the orbit of Pluto.
