I do not believe that pure energy has been defined. The BBT is a theory and as such it does leave many unanswered questions, but it is the best thing going to date as far as nucleosynthesis.
Perhaps if there were a pure energy and it did have gravity it was homogenous with 0 gradiant. Once the energy began to "clump" a gradiant was formed that forces the "pure energy" zero gradiant away from the clumps and generates dark energy. Or perhaps it is a new physics we do not yet understand.
BTW, I am not an astrophysicist, though I love the science...not so much the math.
