Grateful to live in this age where scientific understanding enables us to be even more gobsmacked by the wonders of life, the universe and everything. Galaxies!
Wasn't that long ago in the state of human knowledge it was thought the Milky Way Galaxy alone comprised the entire universe ... now it is thought there could be 200 million to 2 trillion of them! And further back in history there was a time when it was completely unknown what stars really were, what they were made of, how far away they were, and that was just the ones that could be seen. Now it is thought there may be on the order of 10^24 stars in the universe ... more than the number of grains of sand on the entire Earth!
Grateful to be gobsmacked and also to envision a time many years hence that will make our current comprehension appear naive.
