The Quantum Event in the Starship

People in the starship are moving differently in the two universes as a result of the marriage decision. So light bounces off them differently, and some of it leaves the starship through portals marking the two universes. A wave of on between the universes spreads in all directions through space. And so the further the wave travels, more nearly spherical becomes. It becomes, so i shall call it a sphere of differentiation. But soon, even before anyone broadcast intentionally, some of the information will have leaked out.
