Simulation modeled the evolution of the universe from just 50 million years after the Big Bang to the present day

The information can be used to tell us the assembly history of our galaxy

Rock soil droplets formed by heating most likely came from Stone Age house fires and not from a disastrous cosmic impact 12,900 years ago, according to new research from the University of California, Davis. The study, of soil from Syria, is the latest to discredit the controversial theory that a cosmic impact triggered the Younger Dryas cold period.

The detection of gravitational waves by the BICEP2 experiment at the South Pole supports the cosmic inflation theory of how the universe came to be. The discovery, made in part by Stanford University Assistant Professor Chao-Lin Kuo, supports the theoretical work of Stanford's Andrei Linde.

Berkeley Lab scientists and their Sloan Digital Sky Survey colleagues use quasars to probe dark energy over 10 billion years in the past.
