The concept of an "edge" or "center" of the universe can be a bit misleading when discussing the observable universe. The observable universe refers to the portion of the universe that we can potentially observe from our vantage point on Earth. It is defined by the distance light has had time to travel since the Big Bang, which is approximately 13.8 billion light-years in all directions.
However, it's important to note that the observable universe doesn't mean that the universe ends at that distance. The universe is thought to be much larger and likely infinite in extent. Beyond the observable universe, there may be regions and structures that are simply beyond our observational reach due to the finite speed of light.
As for reaching the "edge" or "center" of the observable universe, it's not possible within the framework of our current understanding of physics. The expansion of the universe, as described by the theory of general relativity, suggests that galaxies and other cosmic structures are moving away from each other, with the rate of expansion increasing over vast distances. This expansion makes it impractical for us to reach extremely distant regions of the universe. Moreover, the concept of an edge or center of the universe is not well-defined within the context of the expanding universe.
It's important to recognize that our understanding of the universe is continually evolving as we gather more data and develop new theories. Future advancements in technology and scientific understanding may provide us with new insights and perspectives on the nature of the universe beyond our current understanding.
