Universology literally means "the science of the universe." It is the ongoing study of the principles and truths that interconnect all domains of human knowledge. Popularizing universologic science was a life's work for 19th century intellectual Stephen Pearl Andrews, a futurist utopian. The word can be used synonymously with consilience, a term Edward Osborne Wilson has popularized with his writings elucidating the apparent unity of all knowledge. [The word can be so used, but whether one ought to so use it is a different matter.]

In recent years, Dr. Mamoru Mohri, Japan's first astronaut and Director of Japan's National Museum of Emerging Science and Innovation , has popularized and expounded on universology. For Mohri the universological worldview was an epiphany after seeing the planet from space on two missions in the 1990s, and he has become the chief proponent of universology today. "Everything in this universe is part of an uninterrupted sequence of events" Mohri has said.

Universology, with its relativist and human-centered perspective, has vast implications for religion, philosophy and the practice of natural and social science.

In 1872 Andrews published The Basic Outline of Universology which was subtitled An introduction to the newly discovered science of the universe, its elementary principles, and the first stages of their development in the special sciences.
