Our Observable Universe vs Actual Entire Universe
The observable universe is the part of the universe that we can see from Earth or observe through telescopes and scientific instruments.
On the other hand, the actual universe refers to the entire universe, comprising everything that exists, whether seen or unseen. It is much larger than the observable universe and is believed to extend beyond what we can currently observe, even with our most advanced instruments.
This difference exists because light has a finite speed, and as the universe is thought to have a finite age, light emitted from objects located beyond a certain distance from us has not had enough time to reach us. This boundary is known as the "light horizon," which represents the limit of the observable universe.
The actual entire universe may be substantially larger than the observable universe and may contain structures and objects we can never see or detect. This is because they might be located beyond the light horizon or could be composed of particles or other matter that does not interact with the light or other forms of radiation that we can detect.
