A4_2 Walking on Sunshine

Abstract

This paper investigates the solar power output necessary for someone to be supported against Earth’s gravity by radiation pressure alone. By making some estimates regarding human proportions, and calculations based on known information, it shows that it is not feasibly possible to walk on sunshine as the radiation flux from the sun is around 3 billion times too small. Further that it would require a very large increase in solar mass to come anywhere near possible - roughly 530 times the current mass.
