The Most Unknown is an epic documentary film that sends nine scientists to extraordinary parts of the world to uncover unexpected answers to some of humanity's biggest questions. How did life begin? What is time? What is consciousness? How much do we really know? By introducing researchers from diverse backgrounds for the first time, then dropping them into new, immersive field work they previously hadn't tackled, the film reveals the true potential of interdisciplinary collaboration, pushing the boundaries of how science storytelling is approached. What emerges is a deeply human trip to the foundations of discovery and a powerful reminder that the unanswered questions are the most crucial ones to pose. Directed by Emmy-nominated and Peabody Award-winning filmmaker Ian Cheney (The Search for General Tso, The City Dark) and advised by world-renowned filmmaker Werner Herzog (Fitzcarraldo, Aguirre, The Wrath of God, Grizzly Man), The Most Unknown is an ambitious look at a side of science...

Sometimes you don't even want to know the answers to some questions. Not to mention that there is only so much we can remember anyway. Some are more gifted in certain departments (mathematics, physics, remembering stuff and other things) than others. Are you interested in scientific questions? A book might also be a good place to continue to explore that curiosity by the way.

But if you want a more digestable, short foray into the mindset of some really wicked minds and the things they deal with everyday (or at least most time) and what conclusions they have come up with - well you could do worse. This most likely will not change your life forever - at least that is true for most of the people who'll watch this. If you take more from this than the average viewer though: good for you. Since I watched it on a streaming service I can't tell you if there is a Disc version that has features you may want to explore.
