Observable Universe Vs Actual Universe (Hindi)

The Observable Universe is the part of the universe that we can observe from Earth or any other location in the cosmos. This part is limited by the distance that light has had to travel since the Big Bang, which is approximately 13.8 billion light-years in all directions. Beyond this distance, light from objects has not had enough time to reach us, so we cannot directly observe them. In other words, the Observable Universe is like a "cosmic horizon" beyond which we cannot see.

On the other hand, the Actual Universe refers to everything that exists, regardless of whether we can observe it or not. It includes regions beyond the Observable Universe that we cannot directly observe due to the limitations of the speed of light. Although we can only observe a finite portion of the universe, the Actual Universe is believed to be much larger and may even be infinite.
