Interesting post @chbartist. I haven't spent a lot of time thinking about astronomy in the past, except when I watch movies like Interstellar, Gravity and The Martian. However, the information in your post makes me want to learn more about it. I did also listen to a pretty good audible book on various dimensions and how our universe might just be one of many, and that there might be someone just like us on another universe in a different dimension. Good points about the trivial things that we concern ourselves with, as compared with the big picture of the Universe. I will try harder to live ever moment of the rest of my life as best as I possible can. A big hug back to you and everyone else.
