Parallel Convergence

In our world, there are a hundred million things that are still beyond human understanding. From the Big questions about time, space, our beginning and our end, to the smallest of conundrums like why ice is slippery or how bicycles actually stay upright. All these questions still need answering.
String theory and quantum physics has advanced far enough that many Panacea scientists don’t just believe there are other worlds, they know they exist, running parallel to our own. Hundreds of them. Millions of them. Maybe even infinite worlds. What sort of questions do those worlds have? Which ones have they already answered, and what powers and forces are they exposed to that we are not?
And what exactly would happen if something from those worlds crashed into ours?
== Theory of Parallel Convergence: ==
The theory of parallel convergence is where two counterparts from different realities collide together into one reality. Thus becoming a singularity to unknown effect.
It is theorized that such an effect for a being possessing a mind, soul and spirit the joining two would result in madness and or death.
