SINE

Aura thought this title presents what I mean, because everything we know is like birth and death. The material you are goes back. Anybody can see stuff go back. Dust to dust.

But scientist Carl Sagan was good with words. So I remember:

Carl Sagan, Cosmos (New York: Random House,1980), a summary of pp. 24, 30-31, 38, 218, 224-225:

First hydrogen, from Big Bang. Everything weighs, even hydrogen. If weight, gravity and attraction. So hydrogen nuclei hit, make heat, fuse. Four together make helium nucleus. Hydrogen plus helium, is entire universe, except one percent. But these two elements start up the last one percent : three helium nuclei make a carbon nucleus; four, oxygen; five, neon; six, magnesium; seven, silicon; eight, sulfur; and and and until every element exists. Stronger collisions of heavier and heavier elements makes greater heat until there are stars. Mixing and heating elements makes molecules, more complex ones are organic molecules until you have sDNA. So evolution starts with molecules and then gets more complex as different kinds of organic molecules join together and then you have cells. Cells coming together and reproducing leads to whole civilizations of cells, like people make cities. So it's no surprise the human body includes many species of bacteria where most get along with body, except sometimes some other species don’t. It may seem like a hodgepodge, but the components are complimentary. More and more complexity develops, on earth, and everywhere. Radio telescopes see organic molecules in space, and Sagan's friends at University found a meteorite with amino acids that make life.

So, from what seems nothing, hydrogen gas, comes the most complex thing we know: us. And we go back to what seems nothing. Planets and stars also.

Oh ! That remind me. New company making new plastic from old plastic in a few hours. I'm going to tell Aura and make her happy. Coronado, too: Maybe he'll buy stock and make some money.
