I thought it might be interesting to have a think about this:
After Hawking switched gears away from his previous convictions that black holes destroyed information (Hawking Paradox), he came up with the idea that only some of the supposed parallel universes possessed black holes, and others did not. Therefore, although the information was lost in some, it was kept in the others, and ultimately the universes that lacked black holes would remain after those with black holes had essentially destroyed themselves.
Curious thing is, we have detected black holes within the same universe as we perceive ourselves. So, what does this mean for us? Are we ultimately on the dead-end path? Further, does it matter? If these universes are parallel, it may hold that an exact self exists in each universe, inseparable from the next in detail and self. In such a case, we could very well be losing parallel "instances" of ourselves all the time.
