There is very good reason. The more recent thinking has produced the idea that BBs are happening all the time, and that each BB cuts itself off immediately and completely from its parent structure. There are an infinite number of universes and an infinite number coming into being each instant. This happens as relief to stress in the cosmos and it will never end. Our own personal BB ocurred 14 billion years ago. Nothing special. Current thought on the subject.
Questions for you, RW: these stress relievers occur in the spacetime bubble of our reality or outside of it, then intersect our spacetime to then disappear? Our 'BB' brought space and time into being, or the 'BB' happened in an already existing spacetime background?
...and no one has a picture of a ghost because they are too shy to be photographed.
