An idea
Deep time
Things that take longer than a life
Some of the best science happens too slowly to watch. A cave grows an inch of stone in a century. A fossil takes millions of years to become rock. A star takes longer than that just to switch on.
There is something steadying about this at bedtime. Most of the universe is not in a hurry, and a great deal of important work gets done by simply continuing.
