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 thatπ
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.
