What I mean is. It’s only what we can observe, right? So is it like, there’s a big universe, and we’re shining a flashlight jnto it, and as the Earth and Sun move through the universe, we’re seeing different parts of the whole, and losing others? Or can we just see to an observable “edge” that isnt centered on us?

As it is, the “observable universe” only ever changes to include less than it used to, i.e. something that has left the observable universe will never be seen again by you (or seen by anything else before you observe it). The only way for the “observable” universe to include something that was previously not inside the observable universe is if the rate of expansion of the universe decreases.
