This is a sentence of the lesson «Black holes» of the space course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (black hole, gravity, nothing), what happens, when and where, as Mova's frames read it from the tree.
