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 ...

For years, the idea that reality might be a giant computer simulation has lived comfortably in science fiction, philosophy, ...

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 ...

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

Sharla Boehm, a math teacher, spent her summers coding. She’d go on to build what would eventually evolve into the Internet ...

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 ...

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 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 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 ...
