The Unfathomable Size of the Universe

TLDRThe universe is vast, expanding, and seemingly infinite. Astronomers have discovered that the observable universe is just a tiny portion of a much larger whole. The universe may be infinite in all directions, and as it continues to age, more and more of it should come into view. However, the concept of an infinite universe raises profound questions and challenges our understanding of space and time.
