Has the future already already been written? Is time just an illusion? Take a step outside of spacetime with cosmologist Marina Cortês to discover the block universe.
Fundamental physics says time is symmetric - so why does time move forwards for us in a block universe?
Is time real? Are we just puppets living out a future already written? Marina Cortês explains why she thinks time is fundamental and that we don't live in a block universe.
Marina Cortês is one of a growing number of physicists who believe time is fundamental. We ask her about the alternatives theories to the block universe, where time comes first.
Physics tells us that we live in a block universe, containing all of the past and all of the future. What does this perspective mean for our understanding of time, events, and free will?
The possibility that there might be many parallel worlds has just become a little more likely.
In these two short videos the legendary Andrew Wiles talks about what it was like to prove Fermat's Last Theorem, and what it feels like to do maths.

Why are physicists unsure about what it means to say that something has happened? Anthony Aguirre and Sean Carroll explain.
A model of backward causation in which the future affects the past could help unite quantum mechanics and general relativity – and satisfy a challenge thrown down almost a century ago by Arthur Eddington.
Frank Kelly talks about his work on networks and how inspiration can strike out of the blue.
