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 ...

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

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 ...

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 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 ...

For scientists, supernovae are true superstars — massive explosions of huge, dying stars that shine light on the shape and fate of the universe. For a brief burst of time, supernovae can radiate more ...

In this week's It’s Debatable article, Rick Rosen and Charles Moster debate whether we're all living in a computer simulation like the Matrix. Rosen retired as a professor from the Texas Tech ...

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 ...

“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 ...
