Ep 12. To Infinity and Beyond

To Infinity and Beyond is the twelfth episode of the fourth season of How the Universe Works. This episode explores the concept of infinity, which has long been a mystery to scientists and mathematicians alike. From the infinite vastness of space to the infinitely small particles that make up our universe, this episode takes a deep dive into the concept of infinity and its place in our understanding of the cosmos.

The episode begins by examining what we know about the size of the universe. It's estimated that the observable universe is roughly 93 billion light years in diameter, and that's just what we can see from our position on Earth. The actual size of the universe may be even more mind-bogglingly vast, and could well be infinite in scope.

From there, the episode explores the concept of the Big Bang, which is believed to have created the universe roughly 13.8 billion years ago. This momentous event set into motion the series of events that have led to the universe as we know it today. However, as the episode points out, the Big Bang itself is just one part of an infinite timeline of cosmic history.

The episode also takes a closer look at the nature of black holes, which are some of the most powerful objects in the universe. These massive concentrations of matter are capable of warping time and space, and have a gravity so strong that nothing can escape once it's been sucked in. The episode explores the idea that black holes may in fact be portals to other parts of the universe or to other dimensions entirely.

Moving from the cosmos to the subatomic realm, the episode looks at the concept of infinity in quantum mechanics. At this level, particles can exist in multiple states at the same time, a phenomenon known as superposition. The episode delves into the strange and counterintuitive nature of quantum mechanics to show how this concept of multiple states connects to the idea of infinity.

As the episode draws to a close, it returns to the theme of the infinite nature of the universe. Despite our best efforts, it seems that we may never be able to fully understand the vastness and complexity of the cosmos. But as the episode suggests, there is something awe-inspiring about the infinity of the universe that keeps us searching, studying and striving to understand our place within it.

Overall, To Infinity and Beyond is a fascinating exploration of one of the most intriguing concepts in science and mathematics. From the infinite reaches of space to the never-ending possibilities of quantum mechanics, this episode is sure to leave viewers with a sense of wonder and amazement at the universe we inhabit.
