Explaining Relativity - Rebecca Elson

Forget the clatter of ballistics,
The monologue of falling stones,
The sharp vectors
And the stiff numbered grids.
   
It's so much more a thing of pliancy, persuasion,
Where space might cup itself around a planet
Like your palm around a stone,
   
Where you, yourself the planet,
Caught up in some geodesic dream,
Might wake to feel it enfold your weight
And know there is, in fact, no falling.
  
It is this, and the existence of limits.
