PBS Space Time Season 2018 Episode 37 Will We Ever Find Alien Life?

PBS Space Time season 2018 episode 37, "Will We Ever Find Alien Life?", examines one of the most fundamental questions of human existence. With the vastness of space and the seemingly endless possibilities of life, it seems logical to assume that there must be other intelligent life forms out there somewhere. This episode explores the concept of life in the universe by examining the various conditions necessary for life to exist and the likelihood of those conditions being present on other planets.

The episode begins with an overview of what is known about life on Earth, including the basic components that make up life, such as carbon, water, and energy. It then delves into the conditions necessary for life to not only exist, but also to thrive, including the presence of liquid water, a stable temperature range, and a planet's proximity to a star. The possibility of alternative forms of life that do not conform to Earth's conditions is also explored.

The episode details the various methods that scientists have utilized in their search for alien life, including the SETI program, which uses radio telescopes to scan for artificial signals from other planets, and the ExoMars rover mission, which will search for evidence of past or present life on Mars. The episode then discusses the challenges facing the search for alien life, such as the vast distances between stars, the limitations of our technology, and the fact that we are still not entirely sure what we're looking for.

The episode also examines the phenomenon of the Fermi Paradox, which asks the question, if there is intelligent life in the universe, why haven't we found any evidence of it yet? The episode explores possible explanations for the Fermi Paradox, such as the possibility that other civilizations may already be extinct, that they may be deliberately avoiding us, or that they may simply be too far away for us to detect.

Throughout the episode, various experts weigh in with their opinions on the likelihood of finding alien life and what it might look like. The episode concludes with the idea that the search for alien life is an ongoing journey that will require innovation, imagination, and perseverance.

Overall, PBS Space Time season 2018 episode 37, "Will We Ever Find Alien Life?", is a thought-provoking exploration of one of the most fascinating and enduring questions of human existence. Through a combination of scientific fact and informed speculation, the episode encourages viewers to consider the vastness of the universe and the possibilities that lie beyond our own planet.
