Steve Layman’s shares “7 Questions About the Universe That No One Has Answered“:
…There’s also so much mess after 4.5 billion years of geophysics that some of our best information about the planet’s origins come from meteorites and the cratering of other worlds — outsourced. Speaking of other worlds, we’re not even sure we understand where the Moon came from, maybe it was a giant impact, maybe not. For an allegedly clever species on a small rocky planet this is a bit of an epic fail…
There’s an awful lot we don’t know (far more than just the examples here). But the point is not to get despondent, because this ignorance is a beautiful thing. It’s what ultimately drives science, and it’s what makes the universe truly awe-inspiring. After the hundreds of thousands of years that Homo sapienshas loped around, the cosmos can still elude our fidgety, inquisitive minds, easily outracing our considerable imaginations. How wonderful.
