We've gone back to the big bang and seen how fourteen billion years and three generations of stars nucleosynthesized the elements we use to build and power our machines and ourselves. We've looked at the results of three and a half billion years of terrestrial evolution, probably not the only life in the universe, but definitely the only life we know. We talked about five hundred million years of pressure and desiccation, and how | We've gone back to the big bang and seen how fourteen billion years and three generations of stars nucleosynthesized the elements we use to build and power our machines and ourselves. We've looked at the results of three and a half billion years of terrestrial evolution, probably not the only life in the universe, but definitely the only life we know. We talked about five hundred million years of pressure and desiccation, and how they gave rise to the fossil fuels that powered the Industrial Revolution and now present a bill in the form of climate change. | ||
We, as individuals or as a species, don't get billions of years, but only a brief existence, an absurd blink of the eye, our identities and senses of selves arising from a short-lived ensemble of low-entropy neurons, decaying like all things back into the lukewarm slurry of thermodynamic equilibrium. It is our duty in this interim to learn what we can, to improve our species, and to live bravely despite heat death's ineluctable execration. To <i>differentiate</i>. To put energies to use, to work and to extract work. Yet all remain destined for a night that is eternal and without name. One by one they will step down into the darkness before the footlamps. | We, as individuals or as a species, don't get billions of years, but only a brief existence, an absurd blink of the eye, our identities and senses of selves arising from a short-lived ensemble of low-entropy neurons, decaying like all things back into the lukewarm slurry of thermodynamic equilibrium.
