The first episode of 2018 tackles the biggest question of our time: does anyone actually care whether or not we’re living in a computer simulation?

As our understanding of the universe expands, the question of whether we’re living in a computer simulation has shifted from the domain of philosophers into a problem for astrophysics. Because at their astonishingly fast rate of discovery, astrophysicists will be the first ones to know.

We chat to astrophysicists Martin Bell (University of Technology Sydney) and Geraint Lewis (Sydney University) about just how close we are to simulating the world.
