Where we're going, we don't need roads...

Because this is a podcast about time travel and all you need is something to stream us on and an open mind. This is a dense episode with a lot of theoretical scientific principles put into layman's terms. Or at least we tried to anyway.

The desire for time travel, its use in stories, theories of time and the immutable laws of physics and the structure of our universe are all in play in the first half of this incredible episode.

Excellent!
