Four-Dimensional Spacetime, Why Not Less?

Описание к видео Four-Dimensional Spacetime, Why Not Less?

Our universe is four-dimensional, but could it have been less? Physicists have studied lower-dimensional systems both theoretically and experimentally in various materials. We now know that matter and forces behave very differently in lower dimensions.

In this episode, we explore just how different our universe would be if its dimensions were lower, and how these differences could modify cosmology and even life itself. These insights may drastically impact our understanding of the universe and help explain why it is the way it is.
