Physicists have spent decades arguing over whether our universe is a fundamental reality or a kind of cosmic software, and ...

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

A new technique allows complex interactions in materials to be simulated using Monte Carlo simulations thousands of times ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

Could we be trapped inside a simulated reality, rather than the physical universe we usually assume? It’s a tantalizing theory, long theorized by philosophers and popularized by the 1999 blockbuster ...

Physicists have long struggled to explain why the universe started with conditions suitable for life to evolve. Why do the physical laws and constants take the very specific values that allow stars, ...

New high-resolution simulations show one million galaxies forming some 13 billion years ago. It looks like fireflies flickering in the darkness. Slowly, more and more amass, lighting up the screen in ...

A virtual laboratory under development at the University of North Carolina at Greensboro aims to let students experiment with physics concepts without physically being in a lab. Computer simulations ...
