More than you think! In this episode of our podcast we talk to theoretical physicist David Berman to find out more...

In this interview cosmologist Marina Cortês explains how time emerges in a block universe, exploring the arguments for and against this theory, and alternative explanations where time is fundamental.

Time and space form the stage on which events unfold. But what if the stage itself becomes part of the action? We take a brief tour through the history of space and time and see how ideas have changed since the time of Isaac Newton.

Space is the stage on which physics happens. It's unaffected by what happens in it and it would still be there if everything in it disappeared. This is how we learn to think about space at school. But the idea is as novel as it is out-dated.

Space is three-dimensional... or is it? In fact, we are all used to living in a curved, multidimensional universe. And a mathematical argument might just explain how those higher dimensions are hidden from view.
