Zohreh Davoudi: Are we living in a simulation?

Are we living in a simulation?

All life on Earth— living and inanimate, microscopic and cosmic— is governed by mathematical laws with apparently arbitrary constants. And this opens up a question: If the universe is completely governed by these laws, couldn't a powerful enough computer simulate it exactly? Could our reality actually be a detailed simulation set in place by a more advanced civilization? Zohreh Davoudi investigates.

The universe, from atoms to galaxies, runs on mathematical laws with constants measured to parts per million. Some philosophers and scientists now consider whether our entire reality could be a sophisticated simulation created by advanced beings. Researchers are proposing experiments to detect tiny changes in physical constants or a pixel-like structure of space-time, though conclusive proof remains elusive. Any possible evidence must be weighed against other explanations and the limits of human understanding.
