Endophysics literally means “physics from within”. It is the study of how the observations are affected and limited by the observer being within the universe. This is in contrast with the common exophysics assumption of a system observed from the “outside”. The term endophysics has been coined by David Finkelstein in a letter to the founder of the field Otto E. Rössler.
