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

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

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

The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer ...

If you’re interested in VR, you’ve probably thought at least once or twice about the simulation hypothesis—the idea that we might actually already be living in a virtual reality world. Many people are ...

Unless you, dear reader, are a web-scraping software bot quietly pulling this text into a data-hungry LLM, you’re probably a human. And though you’ve likely never seen me in person, you have good ...

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 ...

Simulation theory proposes that our reality is a sophisticated computer simulation, raising profound questions about the nature of consciousness and existence. Simulation theory is a fascinating ...

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 ...

Looking back at the history of computers, it’s hard to overestimate the rate at which computing power has scaled in the course of just a single human lifetime. But yet, existing classical computers ...
