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.

Zohreh Davoudi: Are we living in a simulation?

Are we living in a simulation?

Exploring the cosmos to the quantum scale, our reality's nature—simulation or not—pushes the boundaries of scientific inquiry.

Finite computing power struggles with the infinite complexity of the universe, suggesting space-time might have a fundamental unit.

Detecting minute shifts in natural constants or space-time's fabric could hint at our universe being a grand simulation.
