Why We Will Reach Kepler-452b One Day

NASA discovered Earth’s bigger, rockier, older cousin called Kepler-452b in the Milky Way galaxy. The first near-Earth-size world to be found is only 1,4% of our galaxy’s diameter away. That’s, like, only 1,400 light-years away. You might think we’ll never get there, right? Here’s a little bit of optimism from a fellow redditor.

Imagine, if you will, the awe and wonder of the first humans, who beheld the sight of the sun and the moon and never once even fathomed that we could truly understand them.

Only in the past couple centuries have humans even realized how to achieve altitude, and only in the last couple decades have we realized how to escape the atmosphere.

“Today we’ve reached beyond flight. We’ve reached beyond the moon.”

We’ve reached beyond our solar system, and beheld wonders of astronomy beyond the wildest imaginings of our ancestors. Take a human from a couple thousand years ago. Perfectly literate, perhaps a scholar of philosophy. You show him what humanity has achieved today, and I suspect, after an initial shock, he’d be overcome with joy and wonder, realizing the capabilities of his species that he couldn’t have possibly considered.

I suspect, in some ways, we are like those humans from a couple thousand years ago. We’ve achieved so much in just a century. Perhaps not in our time, perhaps not to the magnitude of galaxies, but I suspect that somehow, humans will once again find a way to break the boundaries of what is considered “possible.” — source.
