PBS Space Time Season 2017 Episode 20 Supervoids vs Colliding Universes!
- June 7, 2017
In the twentieth episode of the 2017 season of PBS Space Time, titled "Supervoids vs Colliding Universes!", we explore the fascinating and complex phenomena of cosmology. This episode delves into two major topics – supervoids and colliding universes – and how they relate to the Big Bang theory and the structure of the universe.
Supervoids are massive regions of space with an exceptionally low density of matter, and they are one of the most prominent features of the universe's large scale structure. To understand the concept of supervoids, the episode dives into the idea of cosmic microwave background radiation – the afterglow of the Big Bang that permeates the entire universe. Through the analysis of this radiation, astronomers have discovered that there are vast empty spaces in the universe where matter is much less dense than in other regions. The episode investigates how supervoids form, the debate over whether they are natural or something else, and the potential impact they have on the evolution of the universe.
The episode then jumps to the concept of colliding universes, which is one of the most mind-boggling and fascinating ideas in cosmology. The idea is that our universe is not the only one out there, but rather there are many others that exist independently. The theory further holds that these universes are not static but are constantly interacting with each other. The episode seeks to explore the implications of such a collision, how it could happen, and what effects it would have on the universe.
The concept of multiverses is one that has puzzled cosmologists for years. The episode delves into the different ways these multiverses could be structured, including the possibility of several parallel universes existing alongside each other. The episode also explores the consequences of the collision between two universes, including a potential enormous release of energy that could change our universal laws.
In addition to supervoids and colliding universes, this episode touches on other exciting topics such as dark energy, dark matter, cosmic expansion, and much more. It explains the basic concepts of these complex phenomena using relatable analogies and graphics that make it easy to grasp to both cosmology enthusiasts and casual viewers.
Ultimately, "Supervoids vs Colliding Universes!" takes us on a journey through the fundamentals of the universe, providing fascinating insights into the vast space that surrounds us. The episode is an excellent addition to the Space Time series, which is full of informative and entertaining explorations of various topics in cosmology and astrophysics. Its detailed explanations and intriguing concepts will captivate space enthusiasts, scientists, cosmologists, and anyone who loves diving into the mysteries of the universe, making it a great watch for anyone interested in understanding the fundamental truths of our existence.
