Do you know what a space elevator is? It's a idea to move payload from the ground to space without a rocket. It's a little pie in the sky now, but like a lot of space-based ideas, it will come to fruition someday.
Hang on with me here. I sort of feel like this idea, this contraption. Are you still with me? Good. Here's the deal. I feel firmly rooted to the ground. My core is strong, deeply planted. But my heart, my soul, my spirit, and an angel. Oh, those wonderful machines. They are what propel me higher and higher. I wonder how high they can go, how much longer their engines can burn. Then I stop, marvel at their power and grace and elegance. And ride with them.
Still with me?
Then ride with me.
