Observable Universe

Observable Universe is the distance that any observable structure can be seen from Earth.

A place where there is a solar system and we. Scientists are still trying to find information about what is out there outside the Observable Universe. There may be 2 trillion galaxies in the observable universe, although this number has been reduced in 2021 to several hundred billion based on data from New Horizons. Assuming the universe is isotropic, the distance to the edge of the observable universe is about the same in all directions. That is, the observable Universe is a spherical region centered on the observer. Every place in the universe has its own observable universe, which may or may not overlap with the one centered on Earth.
