A lot of things that we usually model as events or states can be thought of as processes. Depending on the context, this process lens can
I’m going to go through them in that order because it’s also perhaps in increasing levels of complexity.
When was the last time you looked at the stars at night?
I was hanging out with my friend a few weeks ago, staring at the stars while we talked about the nature of the universe.
It occurred to me that in some ways it’s less accurate to say that the stars “are bright”, and more accurate to say that they’re continually emitting light. I mean, obviously, but really stop and think about it: say you’re looking at the “North Star” (Polaris). It’s about 400 light years away, which means that the fact that you’re seeing light from that direction right now is because of a bunch of nuclear reactions in the star, like 400 years ago. A few seconds later, you’re seeing new light, made from some more nuclear reactions. And on and on.
And that light is being continually sent out in all directions. There’s a giant sphere radiating out from Polaris of light-from-400-years-ago. There’s another sphere of light-from-500-years-ago, which is a thousand light-years across (Earth is inside this sphere) and still expanding. The sphere of light-from-300-years-ago is also gigantic, but won’t reach Earth until the 22nd century. (If you’re reading this in the 22nd century or later, then OMG HI. Please forgive this claim which is now false.)
So the light you’re seeing isn’t just the state of things. It’s a process that is continuously happening.
