Life - A Cosmic Story

One redwood looms large, until we approach its branches and enter one of its leaves, adjusting our perspective to microscopic scales inside a cell. We see a pared-down version of its inner workings, learning about the process of photosynthesis and the role of DNA. This scene sets the stage for the story of life.
We then leap backward billions of years to the origin of elements themselves. The early Universe contained mostly dark matter, which drew hydrogen and helium together to form the first stars. The carbon and heavier elements required by living organisms came from generations of stars.
