@maunas24-10-13,
Under this topic some years back (2013-2014), i had suggested, using the logic of till date repeatedly proved theory of relativity and earlier proved laws of physics, that, mass= energy= time= space= force. So asking where did the dark mass reside before the big bang, when there was no universe (space), is like asking, WHERE DOES THE SPACE RESIDE?
Like steam, water and ice, "mass , energy, space, time and force are different phases of the same entity, the fundamental entity of existence, and, these phases themselves are all of existence creating the universe, so, they can exist independent of any preformed universe or a big bang singularity point of any universe.
