In this conversation, Neil deGrasse Tyson and Kerstin Göpfrich discuss whether life elsewhere in the universe would share Earth’s familiar DNA–RNA–protein system or emerge through entirely different biochemical pathways. They explore the dominance of carbon-based life over potential silicon-based alternatives, the question of whether evolution would always reach the same solutions, and how synthetic biology might help recreate new forms of life to test these possibilities. The discussion concludes with the mystery of molecular chirality—why all life on Earth is built from left-handed molecules.
