A new research paper reframes the simulation hypothesis, asking whether reality could be simulated and what science can test.

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 ...

Physicists have spent decades arguing over whether our universe is a fundamental reality or a kind of cosmic software, and ...

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 ...

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

What if we are merely part of an experiment by an advanced civilization? To the Editor: Re “Are We Living in a Computer Simulation?,” by Preston Greene (Sunday Review, Aug. 11): Let me get this ...

This amazing 3D map was developed by a team from Durham University in England, revealing the correct locations and properties of local group galaxies. Using a supercomputer, the simulation was ...

The simulated universe theory implies that our universe, with all its galaxies, planets and life forms, is a meticulously programmed computer simulation. In this scenario, the physical laws governing ...

We have long taken it for granted that gravity is one of the basic forces of nature–one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...

Researchers at the University of Waterloo have built what they claim is the most accurate simulation of a functioning brain to date. Despite a seemingly unimpressive count of only 2.5 million neurons, ...

Musk's theory that we're living inside a computer simulation is nothing new. But it is the worst possible time to be talking about it. Chris is a veteran tech, entertainment and culture journalist, ...
