There is such a concept in cosmology - the observable Universe.
It is the part of the Universe we are theoretically able to study, see, feel, touch and all that😏
But also along with this concept there is one more thing - the metagalaxy
This is that part of the Universe relative to us, earthlings , which is really available to us for study and observation due to the limitations and imperfections of our instruments.
Picture: The observable Universe, including the solar system at the center, and as it moves away from the center, nearby stars, the Perseus arm, the Milky Way, nearby galaxies, a network of large-scale structures and on the periphery, an invisible part for us.
