I was talking to my highschooler the other day and he said something I’ve been holding onto. I guess his physics teacher mentioned subatomic particles while talking about atoms, and my kid asks, “Where does it stop?”
“What do you mean?” goes the teacher.
And my kid goes, “I thought atoms were the smallest things in the Universe, but now we’re saying there’s things smaller than that. Where does it stop? Are there things smaller than those particles?”
And bless him, his teacher goes, “Y’know, we don’t know yet, but probably.”
So he comes home and now we’re talking about it. And we start talking about how, well, the Universe is infinite, right? It doesn’t have an end. It almost can’t, because even that thing we call the end is just edge of the Observable Universe, because if it has an end, and if it’s expanding, the obvious question is “What’s it expanding into?” Even if it’s empty nothingness, that nothingness is still something, in the end, if it’s space to be expanded into.
And this is all him saying this, but he goes, “If it goes infinitely out, why can’t it go infinitely in?”
And I ask him what he means, and he says that, well, if space goes infinitely out, it doesn’t make sense that it stops going the other way. Like, it seems less likely that we’ve found the starting point – atoms at first, now subatomic particles, maybe later something smaller than that – and everything else just gets bigger from there. So what if there’s an infinite smallness too?
He said he tried telling his friends this stuff and you know how kids are. They tell him stuff they heard in Ant Man, then google some stuff about quantum this and that without understanding what they heck they’re talking about. But, I mean, come on. We do it too.
But then he goes, “Is Time the same way?”
And again, I ask him what he means.
And he goes, “Well, it didn’t start, right? Because how would Time start if there’s a time without…Time?”
And I tell him I don’t think it works that way. He asks me why not, and I tell him that, I guess, I don’t really know.
“So, for argument’s sake,” he goes, “what if there’s always been Time? Like a Forever Past. There’s never been a time without Time and without Stuff. No beginning to it, there’s just always been Stuff, whatever that is.”
Okay…I say.
And he goes, “So then what about the future?”
“Well it hasn’t happened yet,” I tell him.
He says, “Sure,” but in that way you say things when you’re just being polite, and then he goes, “But why not?”
I ask him to explain, and this is what he gives me.
He says that to people in the past, like the 1800’s, we’re living in their future, and it’s real to us, so why wouldn’t it be as real for them, even if it hadn’t happened yet, because bottom line, our present, their future, is a real thing, and right now proves that. So why not the same for our own future? If Time goes back forever, without a Beginning, just always being, why wouldn’t it be the same for the future? The same way there’s an infinite expansion to space, going forever outward, getting bigger, why can’t there be an infinite smallness?
So, he says, the same thing we did for space, accepting that it goes infinite in both directions instead of just the one, what if we say the same for Time? There is no end to it. There will never be an End to it, just like there was no Beginning. It just…is. Everything didn’t just Begin, it always Was.
It’s had me messed up. He’s at his mom’s now, but I’m still up thinking about all this. It’s changed how I look at the Future. I used to think that determinism or Fate was at odds with Free Will, but I don’t know so much anymore. Maybe we’re just characters in a movie, everything in every way already determined in some unknowable way, but us, here, now, in our freedom to choose, are going to make it that way. It’s got me thinking about when I die, however that’s gonna happen, and wondering if when it happens, I’ll experience it with a wonder like, “Ah, wow. So this is what it’s gonna be like.”
But mostly, it has me thinking about now differently. Like, if Now isn’t the vanguard of the timeline like I’ve thought, the place where the Future becomes the Now, and instead it’s just somewhere in the infinite middle with the Future set, as real now as it will be when it happens…
I don’t know, I guess it makes me feel like I’m living inside my own memory. I look around and go, “Huh, a lot of this I’m going to forget. But what I’m looking at right now. Feeling right now, hearing, smelling. Sometime, I’m going to be remembering this moment. It’s like I’m alive in the Memory of Some Day, all the time. Makes me remember that even when times get tough, the Good Old Days are happening right now.
…
That, or he got into some reeeaaally good weed, and I need to call his teacher.
