A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

In 1952, at Los Alamos Scientific Laboratory, theoretical physicists Enrico Fermi, John Pasta and Stanislaw Ulam brainstormed ways to use the MANIAC, one of the world’s first supercomputers, to solve ...

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 ...

Physicists have spent decades arguing over whether our universe is a fundamental reality or a kind of cosmic software, and the debate has just taken a sharp turn. A group of researchers now say they ...

What if gravity were informed by the way matter was arranged in the universe — and a sign that we were living in a reality composed by a giant computer? In a new paper published in the journal AIP ...

Unless you, dear reader, are a web-scraping software bot quietly pulling this text into a data-hungry LLM, you’re probably a human. And though you’ve likely never seen me in person, you have good ...

The idea that reality might be a kind of cosmic software has moved from late night dorm debates into serious physics journals ...

Simulation theory proposes that our reality is a sophisticated computer simulation, raising profound questions about the nature of consciousness and existence. Simulation theory is a fascinating ...
