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

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 ...

Using the Frontier supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical ...

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 ...

For more than a decade, MIT Associate Professor Rafael Gómez-Bombarelli has used artificial intelligence to create new materials. As the technology ...

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 ...

Ever since Oxford philosopher Nick Bostrom proposed his simulation argument in 2001, the nerdiverse has attempted to assess the possibility that reality is not really real, that what we experience as ...

A physics informed machine learning model predicts thermal conductivity from infrared images in milliseconds, enabling fast, ...
