In the past two decades a diverse and growing cadre of scholars and educators has been developing a new subject with the colloquial and rather catchy name of "Big History." Big Historians view history on a cosmic scale, claiming that the Big History perspective can yield important new insights about humans in the universe. Big History educators have also suggested that it offers a pedagogical framework capable of eliciting profoundly transformative ways of thinking about one's self, society, the global environment and beyond.
