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 ...

We see countless stars and galaxies sparkling in the universe today, but how much matter is actually there? The question is simple enough — its answer, however, is turning out to be quite a ...

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

Looking back at the history of computers, it’s hard to overestimate the rate at which computing power has scaled in the course of just a single human lifetime. But yet, existing classical computers ...

Let's say we build some ridiculous planet-sized computer — one so powerful it could simulate our entire universe. When you purchase through links on our site, we may earn an affiliate commission. Here ...

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 ...

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 ...

20 years ago, futurist Nick Bostrom published the first draft of his groundbreaking simulation argument, which asks, "Are you living in a computer simulation?" Public figures like Elon Musk and Neil ...
