Space boundaries refer to the limits that define how far we can explore and utilize the universe around us. These boundaries can be physical, like the edge of our solar system, or conceptual, such as the limits of our understanding of black holes and dark matter. They help scientists and researchers focus their studies and understand the vastness of space. In addition to physical limits, space boundaries also include the ethical considerations of exploring other planets and celestial bodies. For instance, the Outer Space Treaty emphasizes the importance of preserving the environment of other worlds, ensuring that we do not harm potential extraterrestrial ecosystems as we expand our reach into the cosmos.
