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 ...

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 ...

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 ...

This chapter considers the potential to scale up the use of simulations and games for science learning. The first section provides an overview of current market penetration of games in formal and ...

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 ...
