Journeys of a lifetime: 7 stories of how the cosmos made you

Journeys of a lifetime: 7 stories of how the cosmos made you

Welcome, weary traveller. You've come a long, long way. You and the world around you are a temporary arrangement of matter and energy that took many billions of years to assemble. Imagine if you could deconstruct it all and trace each part's journey.

Many of the trillions of atoms in your body were forged in the incandescent cores of stars. What did they experience as they travelled through space? Some of the water in our cells has been through dinosaurs. And there are gems that have survived all of Earth's growing pains. Our travels continue: your physical body will eventually return to the stars. Even the act of looking at a distant constellation takes you on a strange journey through time and space.

Come with us on a selection of imaginary journeys that you will never take but, in some way, already have.
