The questions that shape our journey:

Why is there something rather than nothing? How vast is the cosmos? Are there multiple universes (multiverse)? What is the theory of everything? What are the implications of cosmology? The diverse answers to these—and many more—questions give us insight into the nature of reality and our existence.

The topics below represent how we organize our journey to understand Cosmos. We group our videos by specific questions that we ask our distinguished contributors in cosmology, physics, mathematics and philosophy. Explore each topic below.

Deep Laws of Nature

What’s fundamental? What's bedrock reality? What are the deep regularities, things that work the same—always, everywhere—across the universe? Are these regularities "laws"?  Where do they come from?

Our Special Universe

Why do the deep physical laws of our universe seem just right for our existence? What does a "fine-tuned" universe mean? What is the far future of intelligence, human or alien, in the universe?

Science and Religion

Must science and theology conflict? Or together reveal deep reality? Does only science give truth? Is theology archaic? What's best for big answers? Science alone? Or science and theology combined?

Mystery of Existence

Why is there a world, a cosmos, something, anything—instead of absolutely nothing at all, an utter blank? This is the biggest question: Why is there anything at all? What can we learn from “Nothing”?
