A lot of work has been done on the number and chance of detecting extraterrestrial life, but humanity’s accessibility to communication with them, such as a compatible time window or compatible means of communication, has been largely underrated. This investigation analyzes the accessibility of extraterrestrial civilizations to communicate with human civilization and, more importantly, the chance of a galaxy containing accessible life. A galaxy or system containing civilizations is not considered useful unless they are accessible. This paper evaluates certain factors that make a civilization accessible and combines them with the Drake equation to yield an extended equation that details the chance of detecting accessible extraterrestrial habitats within a galaxy. However, this model can very easily be altered to fit most units of habitat(such as a stellar system)
