Main Question or Discussion Point
Where there is explosion, there is usually a concomitant implosion. If the Planck length, L*, demarks an original radius for the cosmos, a collapse therefrom, symmetrical to the big bang expansion of spacetime occurs with the conservation of momentum. This "Big Crush" is omnipresent, sub-Planck length and suggests a connectiveness between all matter. Our reality may exist in mirror image, reflected through the primordial surface of separation, L*.
