The rapid progress of our current levels of technology may shortly deliver us from the chains of mortality. Whether that evolution comes in the form of a biological, technological, or a hybrid advancement, 'eternal' life may be close at hand. However like so often happens, the solution to one problem only opens up the door to the next, bigger, one. In the case of immortality the next problem may be one that no level of technology or knowledge can surpass. the end of this Universe.
Surviving the gap between the destruction of one Universe and on to the creation or location of the next may prove to be the most difficult test of survival of any species, ever. Even though the destruction of one Universe may lend itself to the beginning of the next, the gap between the two may be insurmountable. Whether one Universe ends by collapsing in on itself or simply thins itself out into non-existence, any life existing at that time, in any form, will be facing immanent destruction. Therefore any species nearing the brink of immortality should keep in mind that true immortality may be a formidable task .
