Dr. Vopson argues that we’re living in a simulation because the mathematics behind how the universe functions doesn’t match ...

A new research paper reframes the simulation hypothesis, asking whether reality could be simulated and what science can test.

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

Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks and planets in orbit. A growing group of physicists is now treating that ...

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, ...

Ultracold atoms have successfully mimicked a fundamental quantum effect normally found in electronic circuits.

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 ...

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