The Observable World

The observable world refers to everything we can perceive and measure using our senses or scientific tools, including what we see, hear, and detect through instruments like telescopes or microscopes. It encompasses all matter, energy, and phenomena within our reach, from Earth’s surface to distant stars. This universe is finite in what we can observe, defined by the speed of light and the age of the universe. While there may be more beyond our view, the observable world is the portion of reality accessible to human knowledge and exploration at any given time.
