Worse than that.. If eternity future is possible then why not eternity past..
Eternity past relegates “the Big Bang” to fiction... and could cause some physics people serious headaches..
We’re surrounded by eternity in every direction, to the point that “beginning” and “end,” linear time and even scale would seem to be illusion. Is there not an eternity in every second of every day? Start dividing by two and tell me when you reach the end of it. Ever inward.
Matter is mostly empty space, but it’s still quite solidly real to us. We perceive our surroundings as we do as a result of the senses and faculties with which we are equipped. That does not mean that our perceptions are the end of it, though, far from it. A godlike intelligence awaits even the most ardent atheist if he’s honest enough to investigate and consider all the implications, and is willing to grapple with those implications.
True -- BUT... only IF you consider this created universe to be "all that is and all that ever will be".
It was not science fiction speculation, but rather awe at the incomprehensible temporal, spatial and spiritual boundlessness of "I AM" that led me to consider the very real possibility of endless universes (including "Heaven") beyond this one...
