The universe is the whole external physical environment in which humans find themselves living. It is a four-dimensional space-time continuum consisting of matter and energy. Humans have five biological senses of sight, hearing, touch, taste, and smell by which to perceive everything in the universe. The most powerful human sense is that of sight. The universe is a complex hierarchy of physical structures. It consists of nonliving matter such as planets, stars, and galaxies as well as living matter such as plants and animals. The planet Earth is the only object in the universe known to support life.
