We conclude season 1 of the Irrational Discourse podcast by breaking down the 5 greatest sci-fi movies of all time. While we fully recognize our own imperfections, we sincerely look forward to an off-season peppered with emails from the sci-fi faithful pointing out - in grotesque detail - the fallibility of our conclusions.

Highly debatable, somewhat rational, and hopefully enjoyable, we decided to close out season one with a discussion on our top 10 sci-fi movies of all time. In this episode, we cover #10 down to #6, and likely incur the wrath of our fellow nerds and geeks worldwide.

(Not Explicit) Are superhero movies simply pure entertainment, or do some also present us with life lessons that we can learn from if we delve deep enough and look into the actions and attitudes of our favorite characters? Our guest co-host Joshua again joins us to discuss some of the more meaningful lessons we can learn from the MCU movies.

Is climate change a hoax, or is humanity on the verge of bringing about its own extinction. From carbon dioxide to bovine flatulence, we discuss the various aspects of climate change and global warming in an effort to simplify a highly complex system to better understand the impact we're having on the only planet we can live on today.

Our first Q&A session, covering questions from our listeners on all episodes through Sci-Fi Science, Part 2, with Chris and I being schooled a few times in the process.

A.I. has the potential to convey unimaginable benefits to humanity, if it doesn't eradicate all of us first. From recursive learning gaming programs to benevolent A.I. dictators to paperclip machines gone rogue, we discuss our technological progress towards the singularity and possible outcomes if things don't go exactly as we'd like.

Earth races around the sun at 67,000 MPH in a solar system full of debris left over from its formation 4.6 billion years ago. We've had countless encounters with these remnants throughout our history, with devastating effects to life on the planet. In this episode we discuss the threat these objects pose to humanity, what we're doing to mitigate the risks, and the damage these objects can inflict upon the world if we're not successful in doing so.

Have reductions in the global nuclear arsenals of the world's superpowers minimized the threat we pose to our continued existence, or are we still on the brink of self destruction?

For 200,000 years, our species has been vulnerable to natural threats with the potential to eliminate humanity. Over the past 100 years, our technological advancements have reached a point where we now pose an anthropogenic risk to ourselves. From asteroids and A.I., to nuclear weapons and climate change, we discuss some of the known kill mechanisms that can bring about the extinction of our species and what, if anything, we can do to mitigate the risk.

We continue to "geek out" on a few of the most popular sci-fi series' of the past 5 decades, wrapping up with a dive into the science and physics of Star Trek and The Expanse.
