We see countless stars and galaxies sparkling in the universe today, but how much matter is actually there? The question is simple enough — its answer, however, is turning out to be quite a ...

The visible cosmos may contain roughly 6 x 10^80 — or 600 million trillion trillion trillion trillion trillion trillion — bits of information, according to a new estimate. The findings could have ...

The world's second fastest supercomputer — it used to be the fastest, before its rival machine came online earlier this month — has created the most complex computer simulation of the universe to date ...

Yampolskiy continues this tradition of exploring the boundaries of a possible simulation and specifically exploring ways to escape it. Yampolskiy pulls examples from real-world examples of hacks, ...

File this one under "fun to think about, probably not changing your day job": a new study just dropped that suggests gravity itself might be the smoking gun that our entire universe is one big ...

If we were living in a computer simulation, would we be able to tell we were living in a computer simulation? It's a question that's difficult to answer, but physicist Melvin Vopson of the University ...

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 ...

Scientists made a twin version of our universe, showing the evolution of all forms of matter and energy, in the biggest cosmological computer simulation to date. When you purchase through links on our ...

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 ...

Scientific research is normally about chemistry but this time its history. Researchers are using epic computing powers to develop a simulation of the ancient universe. Some 13 billion years of ...

The Bolshoi supercomputer simulation, the most accurate and detailed large cosmological simulation run to date, gives physicists and astronomers a powerful new tool for understanding such cosmic ...

I was invited by the American Humanist Association to present the arguments of my paper “Natural Evil and the Simulation Hypothesis” at the national conference this past weekend. It was fun: I met a ...
