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 ...

Let's say we build some ridiculous planet-sized computer — one so powerful it could simulate our entire universe. When you purchase through links on our site, we may earn an affiliate commission. Here ...

The notion that we live as characters in someone else’s video game is irresistible to many, even outside of science fiction bookshelves. Googling the term “simulation hypothesis” returns numerous ...

If such a simulation were possible, the simulated universe could itself give rise to life, which in turn might create its own simulation. This recursive possibility makes it seem highly unlikely that ...

Do we live in a simulation? This is one of those questions which has kept at least part of humanity awake at night, and which has led to a number of successful books and movies being made on the ...

The idea that reality might be a kind of cosmic software has moved from late night dorm debates into serious physics journals ...

Physicist Mir Faizal, Adjunct Professor with UBC Okanagan’s Irving K. Barber Faculty of Science, was not out to shatter the dreams of science fiction enthusiasts when he began to study the limits of ...

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 ...

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 ...
