We now know more than we did and now have more questions than we had before - typical of how science often works.
I call science, particularly when it comes to the material bodies that form the yniverse and the elementary particles, and how DNA works, as ever unfolding and neerly infinite “onions” of information - we peel back one layer and the next exposed layer presents questions we did not even know needed to be asked. The “aha” moments answer some questions and present even more questions.
The science is settled.........Until it isn’t.....................
“There are known knowns, things we know that we know; and there are known unknowns, things that we know we don’t know. But there are also unknown unknowns, things we do not know we don’t know.”
― Donald Rumsfeld
