How Might the Force Work?

Leah Ashley, Rowan Reynolds, Robbie Roe


This paper studies how Yoda’s use of the Force (as depicted by the Star Wars series of films) may relate to the energy gained through biological processes. Using a power output of 19.2 kW when Yoda lifts an X-Wing and ignoring ATP recycling, it was found that the hydrolysis of all the ATP both initially present and able to be created in Yoda’s body would not be sufficient to provide the energy for this feat. Therefore Yoda either draws on another form of energy storage in his body, or uses some unexplained aspect of the Force.
