I was reading about seafloor spreading the other day when I came across this gem: 150 million years is just a blink in geological terms, to say nothing of the ancient history of the universe. I was originally thinking geopolitically -- wow, how would the Middle East be different if there was an ocean separating Saudi Arabia from Egypt -- but then I thought about human history. Civilization goes back, what, about 30,000 years, give or take? That's a blip compared to 150 million years. So what will humanity be like one million years ago? 10 million? 100 million? Will we make it that far? Will the Earth still be around? Will we be luminous beings, not this crude matter? Dunno. More questions than answers. What do you think?
