There is a theory that within a Black Hole, in a space which is not yet space, a region of pure potential exists. That is, it exhibits the potential to both exist and not exist simultaneously.
Within this potential exists a singularity.
The singularity has both remained a singularity and instantly become a Big Bang, and this has occurred an infinite number of times.
Every time it happens a new dimension is created, a new universe is potentialised. And every time a new universe births, a new bridge to every other universe is born.
The stage is set, curtains rise.
