understanding infinity (kinship)








.




[...] At that moment, there were 3,​147,​740,​103,​497,​276,​498,​750,​208,​327 atoms in her body. Of her total mass, 63.7 percent was oxygen, 21.0 percent carbon, 10.1 percent hydrogen, 2.6 percent nitrogen, 1.4 percent calcium, 1.1 percent phosphorous, plus a smattering of the ninety-odd other chemical elements created in stars.

In the cremation, her water evaporated. Her carbon and nitrogen combined with oxygen to make gaseous carbon dioxide and nitrogen dioxide, which floated skyward and mingled with the air. Most of her calcium and phosphorous baked into a reddish brown residue and scattered in soil and in wind.

Released from their temporary confinement, her atoms slowly spread out and diffused through the atmosphere. In sixty days’ time, they could be found in every handful of air on the planet. In one hundred days, some of her atoms, the vaporous water, had condensed into liquid and returned to the surface as rain, to be drunk and ingested by animals and plants. Some of her atoms were absorbed by light-utilizing organisms and transformed into tissues and tubules and leaves. Some were breathed in by oxygen creatures, incorporated into organs and bone.

Pregnant women ate animals and plants made of her atoms. A year later, babies contained some of her atoms… Several years after her death, millions of children contained some of her atoms. And their children would contain some of her atoms as well. Their minds contained part of her mind.

Will these millions of children, for generations upon future generations, know that some of their atoms cycled through this woman? It is not likely. Will they feel what she felt in her life, will their memories have flickering strokes of her memories, will they recall that moment long ago when she stood by the window, guilt ridden and confused, and watched as the tadr bird circled the cistern? No, it is not possible. Will they have some faint sense of her glimpse of the Void? No, it is not possible. It is not possible. But I will let them have their own brief glimpse of the Void, just at the moment they pass from living to dead, from animate to inanimate, from consciousness to that which has no consciousness. For a moment, they will understand infinity.

And the individual atoms, cycled through her body and then cycled through wind and water and soil, cycled through generations and generations of living creatures and minds, will repeat and connect and make a whole out of parts. Although without memory, they make a memory. Although impermanent, they make a permanence. Although scattered, they make a totality.

Mr. g: A Novel About the Creation, excerpt




.    .    .




Very slowly burning, the big forest tree
stands in the slight hollow of the snow
melted around it by the mild, long
heat of its being and its will to be
root, trunk, branch, leaf, and know
earth dark, sun light, wind touch, bird song.

Rootless and restless and warmblooded, we
blaze in the flare that blinds us to that slow,
tall, fraternal fire of life as strong
now as in the seedling two centuries ago.

there are less of you than you think, and more







.



What I feel and I know is that I am here now, at this moment in the grand sweep of time. I am not part of the void. I am not a fluctuation in the quantum vacuum. Even though I understand that someday my atoms will be scattered in soil and in air, that I will no longer exist, I am alive now. I am feeling this moment. I can see my hand on my writing desk. I can feel the warmth of the Sun through the window. And looking out, I can see a pine-needled path that goes down to the sea.

[...] A hundred years from now, I'll be gone, but many of these spruce and cedars will still be here. The wind going through them will still sound like a distant waterfall. The curve of the land will be the same as it is now. The paths that I wander may still be here, although probably covered with new vegetation. The rocks and ledges on the shore will be here, including a particular ledge I'm quite fond of, shaped like the knuckled back of a large animal. Sometimes, I sit on that ledge and wonder if it will remember me. Even my house might still be here, or at least the concrete posts of its footing, crumbling in the salt air. But eventually, of course, even this land will shift and change and dissolve. Nothing persists in the material world. All of it changes and passes away.

Probable Impossibilities: Musings on Beginnings and Endings



. . .



Our universe is what it is simply because we are here.

The situation can be likened to that of a group of intelligent fish who one day begin wondering why their world is completely filled with water.

Many of the fish, the theorists, hope to prove that the cosmos necessarily has to be filled with water. For years, they put their minds to the task but can never quite seem to prove their assertion.

Then a wizened group of fish postulates that maybe they are fooling themselves. Maybe, they suggest, there are many other worlds, some of them completely dry, some wet, and everything in between.

The Accidental Universe: The World You Thought You Knew



. . .



Who do you think you are? Imagine there's a version of you that sees all of it. A version that knows when versions are messing with the other ones, trying to get things off track, trying to erase things. A record of all the keystrokes, the storage of all the versions, partial and deleted and written over. All the changes. All truths about all parts of our self. 

We break ourselves up into parts. To lie to ourselves, to hide things from ourselves. You are not you. You are not what you think you are. You are bigger than you think. More complicated than you think. You are the only version of you that is you. There are less of you than you think, and more. There are a million versions of you, half a trillion. One for every particle, every quantum coin flip. 

Imagine this uncountable number of yous. You don't always have your own best interests at heart. It's true. You are your own best friend and your own worst enemy . . . Only you know what you need to do. Imagine there is a perfect version of you. Out of all the oceans of oceans of you, there is exactly one who is perfectly you.
