Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...

New simulations from Princeton Plasma Physics Laboratory suggest that deliberately engineering plasma rotation inside tokamak fusion reactors could dramatically reduce the heat loads that destroy ...

Princeton Plasma Physics Laboratory plans to launch a new AI project, called STELLAR-AI, to lower costs and heighten efficiency for experiments. The program is anticipated to launch in 2027, and is ...

Physicists have shown that simulating models of hypothetical time travel can solve experimental problems that appear impossible to solve using standard physics. Physicists have shown that simulating ...

A physicist has mounted one of the most detailed technical challenges yet against the idea that our universe is a computer ...

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 ...

In an essay for The Conversation, physicist Melvin Vopson of the University of Portsmouth in England laid out the theory behind his simulation test, which builds on the idea that a “simulated universe ...
