The expanses of space and time separate worlds from worlds enough for sentient species to evolve concurrently. I hope we find some out there that were radio-happy as many years ago as they are light-years away... Good luck to us.
The neanderthals didn't stand a chance, unless of course we weren't so different that we couldn't get it on with each other. That's my hope. Modern humans could use some more mixing and it seems like the stock ran out. Oh well.
Dolphins? Whales? Chimps? I don't know. Breeding with them doesn't seem likely. If they're the next best thing, I hope we don't screw it up too much for them.
Argh. I apologize. I've been trying to wrap my head around relativity lately, you know, for fun, if only to prove that I can. And yes, there are many more interesting things to do in life, more worthwhile, mightier, greater, etc. Everybody needs something to do when they poop.
I half-heard a weird snatch of smarty talk on NPR in the car. I don't know what they said, but while driving and trying to descry the true form of spacetime and listening to NPR, a vision of a fast-moving photon circling about in a blur, making a shell like a gossamer sphere around, well, EVERYTHING else entered my mind. The contents of the sphere were you, me, the earth, the sun and moon, the galaxy, the whole damn universe and, yeah, maybe more, you get the idea.
Light defines our spacetime. Everything we see depends on light. And such a narrow band of it! Ugh. Not only that, but it goes in a straight line that's bent by you and me. And it only goes in a straight line because it traverses through time like us. Argh.
More work to do on that.
I heard a good question again that I wasn't so ready to answer in this stupid state of mind. She asked me who I was.
How is it that I can cut through space and time and still be me? Am I just another thing that travels through the universe continually apologizing to itself that, while it changes, it really doesn't change that much?
I wonder.
