What's the most widely accepted position on this. Was the Big Bang a

completely devoid of any matter other than the point at which the Big
Bang occurred?

Even if it were dimensional uncurling, you'd still need the energy of an
explosion to uncurl them.

This seems right, unless there is some other means, yet unknown,
hiding in the background. Gordon
