That portion of the universe from which light from distant objects can reach us which has been traveling since it was possible for light to travel through the universe (about 380,000 years after the Big Bang)
This is a sphere centered on Earth extending 46.6 billion light years in all directions. That sphere gets slightly bigger every day.
Note also that even though the universe is 13.798 billion years old the observable universe is larger becuase the universe has been expanding during that 13.798 billion years.

In essence, it represents an infinite expanse of potential realities beyond our observable universe.

What do you think astronomers mean when they use the term observable universe?
It means that anything beyond a certain distance (currently about 46 billion light-years away) can't be observed by us, even with the best instruments, because any signal (light, gravitational waves, etc.) from there didn't have time to reach us.Anything within that distance is part of the "observable Universe". The ENTIRE Universe is probably much, much larger than the observable Universe. It may or may not be infinite; we don't currently know.
