Limitations of Physical Knowledge

Physical knowledge is limited because our understanding depends on available tools, methods, and current scientific theories, which can be incomplete or flawed. Certain phenomena occur too rapidly, too subtly, or are beyond our sensory perception, making direct observation difficult. Additionally, some concepts are inherently uncertain, like quantum mechanics, where probabilities replace certainty. Our measurements can also be affected by errors or limitations of instrumentation. Overall, these constraints mean we can never fully know everything about the universe; our knowledge is always evolving, subject to refinement, and inherently approximate.
