"The fact that there are so many unknowns should not be confused with the silly notion that we don’t know anything at all. [That] is not an intellectual argument so much as a moral one, a kind of chastisement for arrogating to ourselves the belief that we can understand our physical reality. Hogwash. If you lived a few centuries ago and asked an astronomer how many light-years distant is the Andromeda Galaxy, the answer might be 'What’s a light-year?' (and also 'What’s a galaxy?')... Maybe one reason it is so hard to understand some of the fundamental features of the universe is that it’s outrageous on its face. It is packed with untold trillions of stars and galaxies and planets and moons.... If the universe were much simpler — just a lot of hydrogen and helium floating around — it wouldn’t be as inscrutable. It would be just a big, boring gasbag.... Maybe someday we’ll figure out gravity, cosmic destiny and life on other worlds, but for now let’s just remember that we’re making progress on the great unknowns...."Writes Joel Achenbach in "The Webb telescope is astonishing. But the universe is even more so. This new tool can’t do everything, but it’s capturing some of the first light emitted after the big bang, and that is already revealing wonders" (WaPo).
