In the going, however, there’s risk. Many have died in getting to Earth’s poles, mountaintops, and deserts. Imagine the level of risk in going to Mars, a planet that isn’t very much Earth-like. Assuming Musk’s dream reaches fulfillment, what’s after Mars? A trip to Kepler 22B, the exoplanet that appears to be both Earth-like and positioned around a sun-like star? Mars will take months to reach. Kepler 22B will take centuries. You’ve seen the science fiction portrayals: Ships large enough to support primary producers and their human consumers. Radiation-free travel. Centrifugal force as portable gravity. A second, third, and twentieth generation of travelers with little sense of life on Earth.
Assuming we can overcome the physical constraints, can we also overcome the psychological ones? Take a trip to a Mars-like desert on Earth, say Las Vegas. Look how we converted the wilderness! Look how we overcame the difficulties of desert life. We found water, a source of power, and a way to get a constant supply of buffet delicacies. How hard could it be to do the same on Mars? But we do have one largely unresolved problem: Human interactions. We still haven’t solved age-old problems.
We’ve tried, of course.
We’ve invented governments, philosophies, religions, communes, and dictatorships, all in the hopes of achieving something no place can give: Consistent peace among many. Is it because there’s “just never enough.” Of what? Of anything. Find water in a desert, and the next goal is to make a waterpark. Find food, and the next goal is filling buffet tables. No government, philosophy, religion, commune, or dictatorship has ever resolved the problem for many nor resolved the problem over multiple generations.
Satiated? Then you are the exception, but are you being honest? Make any changes to your place? Desire any changes? You know what will happen on Mars. The same things that happen on Earth. We can migrate, but we take—this sounds silly—ourselves with us. This is not an argument for status quo. We have inhabited new “worlds” because there’s “just never enough.” It is an argument that wherever we go—southern Nevada, Mars, or Kepler 22B—we will still think there’s “just never enough.”
