Eternal, in any of these writings and contexts, is simply a forward-eternality unless explicitly described otherwise. There is no way for contemporary human consciousness to comprehend or rein the notion of an eternality of consciousness that extends into our perceived “past.” The implications injure not only notions of free-will, but the fundamental bio-machinery that affords us any perception or sense of existence.
If you claim otherwise that any of us can conceive of an all-encompassing “solidification” of Time, you are either a jerk, or you need to get in touch with me.
The rendering of eternal consciousness essentially requires, due to the limitations of our own potential to conceptualize, the solution of Time, and most likely Spacetime. And the outcomes of that inevitability are fundamentally incomprehensible in anything other than wild and delightful speculation—speculation being, of course, the greatest human pastime thus far. Our bio-hardware is incompatible with the full digestion of the notion, and to me, that’s why evolution is imperative.
The death of the planet, and the intervening demonstrable loss of perceived and perceptible information begs the urgency. We are perceptive enough to render a prediction with a level of belief nearing abject certainty (a catchy, but problematic word, I admit) that our terrestrial home will become fully inhospitable to any form of “known” life (‘known’ here is not throwaway, it is critical to accepting where we stand empirically in this phase of species-development) in 5 billion years when our local sun red-giants us, slagging anything that approximates biology. As far as we “know,” as far as every shred of evidence we’ve been able to collect scientifically demands, humanity is far and away the best chance at preserving even the simplest strand of this planet’s biological history. It is also extremely hard to imagine that, taken to task, given five billion years of technological development (which, aside from local hiccups and sharting backslides, has been a clearly progressive, accreting process that embeds within each new ‘discovery’ the remnants of all previous conscious ‘discoveries’… technology is an ever-burgeoning adaptation of environment to human needs and wants, the proverbial ) what can’t the human animal and its descendants accomplish? Is your personal creativity so lacking or pessimistic to realize that anything we can currently conceive of (and later, I will investigate this as the illumination of human mythos and narrative) cannot be accomplished by then?! At the very least, with survival instincts collaborating with our ingenuity complex, we will have found a way to exempt ourselves to some extent, and probably many, many forms of life and matter (energy seems to innately demonstrate its own path out), from this impending peril. (Admittedly, energy is the guy to bet on, but if we construct ourselves into ordered energy—watch out! Now we’re cooking with gas!)
