Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Researchers at the University of British Columbia Okanagan have published a mathematical argument that, they say, rules out the possibility that this universe is a computer simulation. The claim, made ...

For years, quantum computers have carried a bold promise. They could solve problems so complex that even the world’s best classical computers would fail. That promise fueled a global race among ...

Scientists in Germany have pulled off a staggering computing feat by fully simulating a 50-qubit quantum computer for the ...

Undergraduate science labs were once pretty predictable—pulleys and circuits, rocks and minerals, titrations and unknowns, bacterial brews and pickled piglets. But today’s science lab student, in one ...

Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve. Why do the physical laws and constants take the very specific values that allow ...

“A sun of our own and it’s made in Britain!” crowed the headline. The UK Atomic Energy Authority (UKAEA) believed its 120-ton experimental reactor Zeta was almost certainly generating neutrons from ...

A multi-institutional team became the first to generate accurate results from materials science simulations on a quantum computer that can be verified with neutron scattering experiments and other ...

There’s a 50 percent chance we’re living in a computer simulation, according to new analysis. A scientist from Columbia University in the US claims it’s not too far-fetched to suggest our reality is a ...

A military planner at the Joint Forces Command in Norfolk, Virginia, watches a battle unfold without taking his eyes off the computer screen. The software is tracking a million vehicles spread over ...

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 ...
