Can Time Flow in Multiple Directions?

In this episode, we dive into one of the most profound mysteries in modern physics: the arrow of time.
While our daily lives march relentlessly from past to future, the fundamental equations of the universe don’t actually care which way time flows; they work perfectly fine in reverse.
We start by exploring the traditional explanation for this one-way street: entropy and the thermodynamic journey from order to disorder.
But then, we push into radical new territory. What if the Big Bang wasn't the absolute beginning of a single timeline, but a "Janus Point"—a cosmic mirror where time split into two futures heading in opposite directions?
We examine the mind-bending theory proposed by physicist Julian Barbour, which flips cosmology on its head by suggesting that time isn't driven by a universe slowly degrading into chaos, but by a relentless, beautiful growth in complexity and structure.
