Many years ago, I was walking through Maiden Lane in Chicago's Old Town and I heard music from the record store - a new band. I was so impressed that I immediately went in and bought their album - Led Zeppelin. It did not disappoint! A few years later, they released a song that is considered one of the best rock and roll songs ever made.
I use this as an example of starting at "great" & evolving to "greater" (& hopefully even greater!) And also - because the song itself talks about what I'm thinking about today. A Stairway to Heaven...
Imagine a real stairway to the heavens! Or rather... an elevator/escalator! That's what scientists and students do in all kinds of competitions to build viable systems that are able to carry rocket ships, etc. through and beyond the atmosphere - thereby saving vast quantities of fuel and wear & tear on the ships that happens at launch & during the journey to beyond earth's gravitational pull.
I, personally, love thinking about this stuff! I am not a scientist, so I doubt I'll be building any stairways to heaven myself - but I contemplating the future - knowing it can be great & greater... and that things only imagined right now will someday become reality.
What sorts of future items are you anticipating? I'd love to know! :D
