The Curious Dynamics of Particle Interaction in a Toroidal Universe
1:26:27 - 1:30:53 (04:25)
This podcast explores the curious behavior of strings in higher-dimensional boxes, specifically in a toroidal universe, and how these dynamics differ from those in our four-dimensional reality.

In string theory, the universe can be imagined as a tiny nine-dimensional box that stretches as the walls of the universe grow, causing the strings to become very massive.

In order for strings to disappear in string theory, they must find each other and form a new state, but how do they do this?

Summary
In order for strings to disappear in string theory, they must find each other and form a new state, but how do they do this? By moving through the dimensions, but if the dimensions are too big, they may never find each other.

In higher dimensions, mathematicians use surgery to maneuver dimensions, but in four dimensions, they can't be moved as easily, which is why it's so complicated.

Summary
In higher dimensions, mathematicians use surgery to maneuver dimensions, but in four dimensions, they can't be moved as easily, which is why it's so complicated. This may explain why string theory posits three extra dimensions instead of four.
