This episode examines the plausibility of life on other worlds, how it might evolve, and what it might look like. Hawking takes the audience on a 13.8-billion-year journey examining our own origins, describing the conditions necessary for life to evolve, and then hypothesizes the likelihood of it happening elsewhere in the universe.
The title says it all—this is the journey from where the universe started to how we believe it could end. But this is not a religious creationism story. This story is brought to us by the awesome powers of science, which employs quantified knowledge obtained over hundreds of generations. There are few more qualified than Stephen Hawking to explain this grand journey of how the cosmos started and how it might end. Students just need to sit back and watch. (And fill in the documentary guide!)
Hawking delves deep into the concept of time travel, but artfully keeps the conversation interesting and understandable for the students. He uses a logical and scaffolded approach to explain what can sometimes be considered a counter-intuitive and difficult-to-follow concept.
