Kate Mitra: [Voiceover] ... Some of us on Columbia 7 don't make it to 21. Something about their lungs not adjusting to recycled air. I've read a lot about what it was like growing up on Earth. I can only read and wonder. I've never been there. In the beginning, our sun was created to give light and life to the earth on which we lived. Our planet was just the right distance from the sun, sustaining amazing diversity of animals, plants, and people to populate it. But, what once sustained our lives would soon be the end of it. When the Earth fell out of orbit, we tried to reset the planet with the use of particle accelerators. As a result, wormholes were created throughout the galaxy. Temperatures on earth skyrocketed beyond anything ever seen before. All the water eventually evaporated. Without water, all the plants died. Without plants, all the animals died. Before mankind died as well, seven ships made it off the surface. That was 40 years ago. Each ship went off in search of another planet. One that could support human life. For 37 years we searched in vain. The only thing we could secure it, is train.
