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.—Alan Lightman
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.
