“The atoms of our bodies are traceable to stars that manufactured them in their cores and exploded these enriched ingredients across our galaxy, billions of years ago. For this reason, we are biologically connected to every other living thing in the world. We are chemically connected to all molecules on Earth. And we are atomically connected to all atoms in the universe. We are not figuratively, but literally stardust.” ― Neil deGrasse Tyson
Opening line of “The restaurant at the end of the universe”
I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of uncertainty about different things, but I am not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here. I don't have to know an answer. I don't feel frightened not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is as far as I can tell.
But we have soothed ourselves into imagining sudden change as something that happens outside the normal order of things. An accident, like a car crash. Or beyond our control, like a fatal illness. We do not conceive of sudden, irrational change as built into the very fabric of existence. Yet it is. And chaos theory teaches us … that straight linearity, which we have come to take for granted in everything from physics to fiction, simply does not exist …. Life is actually a series of encounters in which one event may change those that follow in a wholly unpredictable, even devastating way …. That's a deep truth about the structure of our universe. But, for some reason, we insist on behaving as if it were not true. – Ian Malcolm in Michael Crichton's Jurassic Park
