Light Pushing Asteroids

  1. Jan 15, 2014 #1
    Hey what's up! So I'm trying to wrap my head around this concept that light is able to push asteroids in space. I understand the Yarkovsky Effect and how it acts as a propulsion system, but I want to know if light is able to push objects in space strictly based on a collision basis. Can it replicate a simple example where to trains collide into each other; Is light able to act as mass colliding with another object altering its velocity?
