Do You Have a Grandfather?

I, the central point of a cracked vessel bound with chewing gum
Here's the size of my star, or the rate that it burns at
Is this trip a new one? Is my book long enough?
Forget the fiction; I want to remember every second, every inch that I crawl
It's the truth in my choice to move the coil, and jump over holes where I sharpened my heels
