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

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

Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks ...

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

The best theory physicists have for the birth of the universe makes no sense. It goes like this: In the beginning—the very, if not quite veriest, beginning—there’s something called quantum foam. It’s ...

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 ...

Recent theoretical breakthroughs have settled two long-standing questions about the viability of simulating quantum systems on future quantum computers, overcoming challenges from complexity analyses ...

Physical AI converts terrain, drainage, soil variability and sunlight into structured inputs that can be simulated, ...
