Marc Garneau thinks peace would break out everywhere if political leaders had the opportunity to orbit the earth.
You go around the earth in 90 minutes and see 16 sunrises and sunsets. You can see 2000 km in front of you. You see the extremely thin atmosphere. Your perception changes physically and mentally.
We live in a surrounding restriction of 8 km. Space travel extends that restriction. It’s mind expanding. It transforms perspective into a deep concern with the human condition.
Maybe one day it will be part of regular life. But will it bring a utopia? I doubt it. With new expansions come new restrictions.
However, when the space travel experience becomes the convention, at least I’ll be able to leave any planet that I’m sick of because I’ll have a new self-contained atmosphere.
