Imagine you are in a spaceship looking back on earth.

Yesterday, Feb. 27, 2017, brought an amazing piece of news. Elon Musk announced that his company SpaceX will be sending two private citizens on a trip around the moon in 2018.

I truly believe that humanity is now on course to make space travel for any human possible within my lifetime.

Close your eyes and imagine you are in a spaceship looking back on earth as it looks in the image above. How do you think this will affect you?

Now imagine every human on earth has this experience. How will this affect humanity?

When you’re finally up at the moon looking back on earth, all those differences and nationalistic traits are pretty well going to blend, and you’re going to get a concept that maybe this really is one world and why the hell can’t we learn to live together like decent people.
