Out of the blue is still an expression that we see. It originates with something we don't see - a bolt of lightning out of a blue sky. The expression means something unexpected and almost impossible. It is not that uncommon for lightning to strike in a blue sky. It travels horizontally for miles from clouds that aren't that far away. About 30% of people are struck by lightning under clear skies. While lightning strikes before thunder sounds, the rule of thumb is to quickly take shelter when thunder is heard. It means lightning is close.
Jeff Bezos' spaceflight company, Blue Origin, is named for the blue planet. He says it is humanity's blue origin. He "envisions a future where millions live and work in space to restore and sustain Earth."
Go and look at the website - it looks to be about getting hold of the resources in space. Here's a quote: "The road to space will be built from the limitless treasures of the solar system. We must learn to "live off the land" to fully realize the promise of space for the benefit of Earth." There's much more of this pseudo-optimism on the website HERE.
So what made me think of these two expressions as somehow related? They both seem a bit silly to me. Out of the blue seems one of those expressions that is an exaggeration. Into the Blue seems like an equal exaggeration.
