Humans have been dwelling around a Population One star for longer than memory can hold. Population Zero stars (by extension and in my fanciful imagination) include all the yet-to-be-born or much younger stars, either still forming or in the galactic process of preparing to give birth to their respective spinning systems; in other words, all the extraterrestrial civilizations potentially out there will naturally come to follow in the wake of our own existence. In a world where travel to other populated stars and their planetary colonies remains a challenging consideration to say the least (or perhaps merely an unreachable dream) there may linger a contiguous possibility of contact with beings yet to manifest in spacetime. It involves the crucial matter of continuing to survive. Talk about getting ahead of ourselves. Never mind. The way forward involves lucid dreaming. Consider the irony that our dream to reach the stars, while potentially not practical in the physical sense, might be transcended by our focus on actually dreaming in order to initiate contact.
A Population Zero Star would be the type, super rich in metals of course, that will soon spawn a good brood of exoplanets that will one day potentially host their own civilization or life-forms. (Remember that here and now, on Earth, we circle about a Population One Star.) Do the math. The best we could do toward establishing some form of contact with a possible extraterrestrial civilization or pristine alien ecology, at least in my view, would be to send a remote sensor device to that system that will monitor its ongoing situation. Of course the main problem with that would be the human race may not survive long enough to begin receiving the feedback. If we did manage to survive that long, by the time that life form's monitored feedback appeared on our radar, they'd be mere hatchlings in contrast to our far more ancient species. They would be newly emergent beings from 'nonexistence' into becoming their very own Population One star life forms. In a super accelerated dream time-sense, communication with this sentience may be possible, and certainly worthwhile attempting. Something of our essence may be imprinted upon them if we were to succeed in contacting them somehow through dreams, for instance. Who knows? They might end up becoming somewhat familiar with us by that method. We could devote ourselves to trying this long distance dream communication. By shouting forward down the right track, we just might put a "whisper into their caboose", so to speak. Again, who knows? We might haunt them yet. Think about what it means to be haunted.
The point which remains actively constructing itself as we move along these mysteriously configured celestial pathways together (our potential distant solar neighbors and ourselves) shows how we're separated by aspects of space and time as we somehow manage to each exist independently disassociated from one another. Our very electromagnetic nature may keep us discrete from one another, rather than a perceived failing in our nurtured capacities. Being surrounded every moment by the living void may incur both terror and wonder if pondered over enough, until one makes the connection that by the same token, there may also not be that much to this tangible something of our bodies, minds, and lives. Existence: what, exactly, does it appear to be? There's the rub: appearance must be relegated to that which we perceive. It may just as easily appear to us that we aren't merely scaled-down sentient bipeds in a colossal "cosmarium" (cosmic aquarium) so much as it may turn out that we're actually the entire cosmos itself--experiencing a case of confused identity.
We may not necessarily be able to engage in a practical discussion about things such as interstellar travel and the search for extraterrestrial life for the fundamental reason that life itself, insofar as how we've chosen to define it, may more realistically equate to the entirety of the cosmos plus the surrounding void itself, rather than the limited viewpoint of any one of its microscopic, individual bipedal components. As we unpack the quantum information still streaming in at our disposal (which Einstein greatly facilitated our comprehension of), the strange dynamic of our position within the spacetime continuum in relation to the remainder of our sprawling cosmos should crystallize in our minds and gain more focus over time.
Toward this end I have enjoyed ruminating over various ideas I've had, such as the Law of Inversion (which generally states that truth is usually closer to the opposite of what we assume it to be) with its ties in counter-intuition, and now my POPULATION ZERO idea posits to both resolve the Fermi Paradox as well as provide an ideal designation for the actual location of potential extraterrestrial civilizations or ecologies. Taking relativity into account, if alien wildlife were to appear not with but before and after us in time, then by definition all the old Population II stars and even older Population III stars and their respective life-forms would've gone extinct long before our own inception here, now leaving only stars forming in the wake directly after us which could conceivably become hosts to extraterrestrial civilizations or life-forms, thus neatly rendering their designated area as "Population Zero" stars; solar systems that are yet to be born and mature. Current population: zero.
