gravity

the core - is the center of a gravitional pull- so in the center is a planet (unknown to any planetarium) and the core is revealed, all things around the core are being pulled towards the center - (sorry for my bad spelling i am in a rush)

crash

these are waves, they crash against the rocks, it's plain and simple!

sprout

the theme is sprout and what came to my mind was spring and within growing spring is love - the sprout of a new love and it just so happens to be two boys holding hands (gay love) and even though they are gay doesn't mean that they can't love each other.
