A physicist has mounted one of the most detailed technical challenges yet against the idea that our universe is a computer simulation, arguing that the energy required to run such a program would ...

Researchers have recreated the tumultuous beginnings of Earth, simulating what the planet was like just after its formation 4.5 billion years ago. The results, derived from a new computer model, ...

Computer simulations suggest NASA’s Habitable Worlds Observatory could detect Earth-like exomoons around gas giant exoplanets through reflected starlight and lunar eclipses.
