The Accessible Universe

The Accessible Universe refers to the parts of the universe that we can observe, study, and understand using our current technology and scientific methods. It encompasses everything from nearby planets and stars to distant galaxies and cosmic phenomena that emit light or other signals we can detect. While much of the universe remains beyond our reach, advancements in telescopes, space probes, and theoretical physics continuously expand our understanding. Essentially, it focuses on what we can learn about the cosmos from our unique perspective on Earth and through instruments that help us explore the vastness of space.
