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

For years, the idea that reality might be a sophisticated computer program has drifted from late-night dorm debates into mainstream culture and serious philosophy. Now a new wave of theoretical work ...

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 ...

The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest ...

Is this real life? Is this just fantasy? A growing number of scientists are suggesting that the idea that we are all living in a simulation may not be completely far-fetched. Simulation theory is the ...

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 ...

Just Elon Musk's name is enough to evoke an emotional response in many people, ranging from hope and glee in some to anger and disgust in others. But how about existential dread? It's true that one of ...
