Brian Cox: Why We Exist At All

The physicist and former rock star Brian Cox opens his arena shows with a story about Johannes Kepler walking across the Charles Bridge in Prague on New Year's Eve 1609, caught in a snowstorm, realizing he has no gift for his benefactor. His solution: "I've brought you the gift of almost nothing" — a snowflake — along with a question: Why does it have six corners? Kepler wrote a short book on the subject, The Six-Cornered Snowflake, and at the end admitted he didn't know the answer. "I leave it to future generations," he said. For Cox, that moment marks the beginning of modern science: not the discovery itself, but the willingness to ask why a pattern exists, and to treat not-knowing as an invitation rather than a failure.

Show Notes

What if understanding the universe could change the way you live?

In this episode of Begin Again, Professor Brian Cox joins Davina for a conversation about existence, consciousness, mortality and the extraordinary improbability of being alive at all.

Brian explains why the atoms that make us have travelled across billions of years of cosmic history, why the universe gave rise to conscious life, and how understanding our place within it can completely transform the way we see ourselves. Together, they explore what happens when we die, whether science leaves room for spirituality, why curiosity matters more than certainty, and why accepting that life is temporary can make it infinitely more precious.

But this conversation is about much more than science.

Brian reflects on the book that changed his life, the teachers who shaped his thinking, his unexpected journey from rock musician to world-renowned physicist, and why saying "I don't know" may be one of the most important things we can learn. Davina and Brian also discuss grief, fear, hope, the search for meaning, and why seeing the bigger picture of the universe can make us feel more connected to one another, not less.

This is a conversation about awe, curiosity, purpose and the remarkable privilege of being alive.

If you've ever looked up at the night sky and wondered why we're here, questioned what gives life meaning, or wanted to see the world with fresh eyes, this episode is for you.
