Thanks Beetzart, truly inspiring. My wife doesn't get why I like to engage with the 'big' stuff when I'm depressed, I suppose feeling small helps to put one's troubles in to perspective.
But the blue dot theory doesn't entirely convince me of our smallness in the sense of insignificance. We really don't understand what time, space and reality are. Size may not matter. On theory suggests the whole multiverse may be made of one single electron moving at mind-bending speed. When you see the similarity between the piucture of a brain cell and the universe itself, it makes you wonder.
One thing quantum physics teaches us is how much we really don't understand just by observing the physical universe. Nothing is solid. Things are made of waves, or waves collapsed to a point by an observer. Maybe the observers are actually very important indeed. Or maybe not. I don't claim rights to any great 'truth,' but it's fun looking for it.
