PBS Space Time Season 2019 Episode 22 Did Time Start at the Big Bang?

PBS Space Time season 2019 episode 22 titled "Did Time Start at the Big Bang?" is an exciting exploration of the very beginning of the universe. In this episode, the host explains the complex idea of time and how it relates to the Big Bang theory.

The host begins by taking viewers through the history of time as we know it, from the ancient Egyptians and Greeks to the modern-day standardization of time zones. He then dives into the notion that time is not absolute, but rather relative to the observer.

This sets the stage for a discussion of the Big Bang theory, which states that the universe began as a singularity and rapidly expanded, creating the cosmos as we know it today. The host poses the question, "Did time begin at the Big Bang?" and sets out to explore the possible answers.

Through a series of thought experiments and scientific revelations, the host delves into the concept that time and space are interconnected and that they likely both began at the moment of the Big Bang. He also considers the idea that time and space existed before the Big Bang, but in a vastly different form.

The host discusses the concept of imaginary time, a theoretical construct proposed by renowned physicist Stephen Hawking. This idea suggests that time may not be linear but rather have a complex structure that includes both real and imaginary components.

The host also examines the notion of a "pre-Big Bang" universe, which some theories suggest existed before the moment of the Big Bang. He considers the possibility that this universe may have had its own sense of time, which could be vastly different from what we experience today.

Throughout the episode, the host presents complex ideas in an accessible and engaging way, using vivid visuals and simple analogies to help viewers understand the concepts at hand. He also incorporates interviews with leading physicists and cosmologists, who offer their own insights into the mysteries of time and space.

Overall, PBS Space Time season 2019 episode 22 provides a fascinating exploration of the origins of time and how they relate to the Big Bang theory. It offers viewers a thought-provoking look at some of the most complex concepts in modern physics and cosmology, and is a must-watch for anyone interested in the origins of the universe.
