When you open your eyes you instantly see everything from the close to almost infinitely far away with no lag from distant objects.
It's just the way your brain processes it. The lag is still there, but your brain doesn't know how to work with it. Under the influence of certain
chemicals, you can see how your ancient brain processes distance as time. I suppose it's so you can see a predator coming from a distance and fairly
instantly calculate how long it will take for the predator to get to you, and how long you have to make an escape.
To do this, your brain divides what you're seeing up into fairly flat levels at certain distances away. It's because your eyes and brain don't know
how to process time as a dimension because it's seeing it at a zero degree angle. Like trying to figure out how long a piece of string is if all you
see it one end of it. So your brain divides up the world into objects it can see at different distances. Your hands. The keyboard. The window.
Outside the window. The trees on the street... and so on until we get to the night sky, where your brain sees it as a distant flat surface with
sparkly lights on it.
Our existence consists of lags. Even holding up my hand and looking at it, there is a slight lag between the time the reflected light hits it and my
eye gathers the photons. Then there is an additional lag as my brain processes it to determine where and what it is, and whether or not I should act
on it. So we're already detached from real reality by that amount of time. When you start to deal with greater distances, the lag becomes longer.
But your brain puts it all together and calls it "now." Pretty tricky, really.
I would like to have somebody cook up a simulation of what the night sky would look like if you actually did see it in real time. Where the stars are
in their real positions -- "right now" from my perspective -- rather than what they looked like hundreds or millions of years ago. Could be very
