Is “the observable universe” changing as we move?

312 viewsOtherPlanetary Science

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?

it moves with the observer, but since “observable” basically means “light has had time to reach us” it is also expanding at the speed of light (ish) (this is seperet from space expanding on it own, which is going faster than light, so the amount of stuff in the observable decreases even though it is expanding) which dwarfs any effect from human motion
