In what sense are you using the word imagine, and how hard have you tried to imagine a billion years?

I have a really poor intuition for time, so I"m the wrong person to ask.

I can imagine a thousand things as a 10x10x10 cube. I can imagine a million things as a 10x10x10 arrangements of 1K cubes. My visualization for a billion looks just like my visualization for a million, and a year seems like a long time to start with, so I can't imagine a billion years.

In order to have desires about something, you have to have a compelling internal representation of that something so you can have a desire about it.

X didn't say "I can too imagine a billion years!", so none of this pertains to my point.

First, I imagine a billion bits. That's maybe 15 minutes of high quality video, so it's pretty easy to imagine a billion bits. Then I imagine that each of those bits represents some proposition about a year - for example, whether or not humanity still exists. If you want to model a second proposition about each year, just add another billion bits.

Perhaps I don't understand your usage of the word 'imagine' because this example doesn't really help me 'imagine' them at all. Imagine their result (the high quality video) sure, but not the bits themselves.
