Earth May Have Had a Second Moon
It’s always a good idea to periodically remind yourself how little we really know about ourselves, the world around us, and the history of it all. The textbooks that we knew as children — the subjects which we studied diligently and stressed to pass quizzes and tests for — will likely look radically different for our own children. I, at least, have a tendency to put a lot of faith in what we (think we) know. It’s best not to forget that tomorrow may bring a discovery that demands we unlearn everything we thought we knew.
Hey, back when I was born in 1986, apparently it was still under debate whether babies could feel pain (the general professional opinion was “no”). So, I’m told, heart surgery was performed on my little self without the use of anesthesia. Good times, I’m sure.
