The Transcension Hypothesis is a cutting edge idea about what would happen in the hundreds of years following the technological singularity, a point in time where mankind merges with machine in a runaway technological growth (to the point of unfathomable changes to civilization). It is, quite possibly, the best solution to the famous “Fermi Paradox” problem.
The Fermi paradox postulates that if the universe is so vast and aliens exist, why then, do we not see their structures in the night sky? (or any kind of evidence what-so-ever). The Transcension Hypothesis, by John Smart, is an attempt to answer this question, suggesting that the reason we don’t see any intelligent alien civilizations is that they’ve all left the universe before they even bothered with space travel.
In short, the destiny for ALL intelligent and technologically advanced civilizations is “Transcension”. Which is to disappear out of this space-time reality and into those of our own creations (“baby-universes”, wormholes, etc.) using post-singularity technology. At that point, if your civilization can do such things, why bother conventionally exploring space?
THE FERMI PARADOX
Speculation on the Fermi paradox has grown considerably in the last two decades, as it has become increasingly obvious that we live in a universe that is very likely to be teeming with Earth-like planets, and also with intelligent, curious, and technologically accelerating forms of life.
When we extrapolate our own accelerating progress in science, IT, and nanotechnologies, we can imagine that any one of these civilizations could easily send out self-replicating nanotech that would spread across our entire galaxy within 100 million years (a very reasonable estimate with conventional ideas for interstellar exploration), and beam the information that it finds out to the rest of the universe (or alternatively, just back to the originating civilization), creating a Galactic Internet, and making our universe as information-transparent as our planet is becoming today. So if Earth-like planets likely emerged in our galaxy at least a billion years before ours did, as several astrobiologists have estimated, why don’t we see any signs of this Galactic Internet today? Or signs of past alien visitation, probes, and megastructure beacons near Earth? Or signs of intelligent structures or civilizations anywhere in the night sky? In other words, Where is Everybody? That’s the Fermi paradox.
However, the Trascension Hypothesis implies that once a civilization reaches a high enough intelligence, it could be capable of reaching femtoscopic technological singularity and creating a black hole in order to leave our visible universe (therefore expanding their growth, complexity, and intelligence), disappearing from the universe and reaffirming the Fermi Paradox theory. Our current developments in science suggest that this is a possibility, or at least we’d like to think that this is where the human race is heading.
THE TRANSCENSION HYPOTHESIS
The Transcension Hypothesis holds that the reason we don’t see any intelligent alien civilizations anywhere is that complexity in intelligence eventually stops expanding towards “outer space” (extraterrestrial colonization) and starts improving on “inner space” (neuroscience, mind-uploading, and information technology).
Consider the smartphone in your pocket. It is a thousand times cheaper, a thousand times smaller, and a thousand times more powerful than a computer built only a few years ago. You eventually have million-fold increases in power and cost from computers that used to take up entire rooms and do only the most basic of calculations. You also have the increasing miniaturization of microprocessors which continues onwards. When you consider the fact that mere decades from now, highly intelligent computers will be a thousand times smaller than todays microprocessors you begin to see what’s called “S.T.E.M (Space. Time. Energy. Matter) Compression”
STEM-compression creates more intelligence, more density, more communication, less matter, and sizes that get increasingly smarter. From nanoscale computing on semiconductors to picoscale quantum-computing on atoms, to femtoscale computing on perhaps “Kugelblitzes”, photons, or other subatomic particles. This exponential growth keeps compressing space, time, matter, and energy into smaller and smaller dimensions to the point where we are able to create a Black Hole or Wormhole-like conditions and/or “baby-universes” and eventually disappear out of the visible universe.
In a nutshell, the transcension hypothesis predicts constrained transcension of intelligence from the universe, rather than expansion (colonization) within the universe by intelligence, wherever it arises in the universe. The reason we don’t see advanced civilizations, if the transcension hypothesis is correct, is that the vast majority leave the visible universe as they develop, and the few that do not are very unlikely to be visible to us, with our presently weak SETI abilities, in a universe in which the bias is transcension rather than expansion. That’s a very strong claim. Could it be right?
THE MAIN ARGUMENTS
This essay makes a series of assumptions/proposals about the nature and future of intelligent life in our universe. Most of these key assumptions may need to to be correct, in some fashion or another for the hypothesis itself to be correct.
Here are the key assumptions of the transcension hypothesis, as I presently see them:
- Intelligent life, on Earth and elsewhere in our universe, is not only evolving (diversifying, experimenting), but also developing (converging toward a particular set of future destinations, in form and function), in a manner in some ways similar to biological development. In other words, all civilizations in our universe are “evo devo” both evolutionary and developmental. The phenomenon of convergent evolution tells us a lot about the way development may work on planetary scales. A kind of cosmic convergent evolution (universal development) must also exist at universal scales.
- The leading edge of intelligence always migrates its brains and bodies into increasingly dense, productive, miniaturized, accelerated, and efficient scales of Space, Time, Energy, and Matter (what I call STEM compression), because this is the best strategy to become the niche-dominant local intelligence (and for modern humans, Earth’s biosphere is one precious and indivisible niche), and because the special physics of our universe allows this continual migration into “nanospace“. Human brains with their thoughts, emotions, morality, and self- and social-consciousness, are the most STEM-compressed higher computational systems on Earth at present. But our biological brains are just now starting to get beat at the production of intelligence by deep learning computers, which are even more profoundly STEM-compressed in certain kinds of computation than neurons (for example, electrical interneuron communication in an artificial neural network is seven million times faster than chemical action potentials between biological neurons). Fortunately, accelerating STEM-compression of both human civilization and our leading technologies is stepwise testable, as argued in my paper.
- The acceleration of STEM compression must eventually stop, at structures analogous to black holes, which in current theories appear to be the most computationally accelerated and efficient entities in the known universe. Fortunately, this “black hole destiny” for civilization seems testable via the search for extraterrestrial intelligence (SETI), as argued in my paper.
- A civilization whose intelligence structures are compressed to scales far below the nanoscale may well be capable of creating or entering black-hole-like environments without their informational nature being destroyed. There are 25 orders of magnitude in size between atoms and the Planck scale. This is almost as large a size range as the 30 orders of magnitude presently inhabited by life on Earth. We simply don’t know yet whether intelligence can exist at those small scales. My bet is that it can, and that STEM compression drives leading universal intelligence there, as the fastest way to generate further intelligence, with the least need for local resources.
- Due to nature of general relativity, extreme gravitational time dilation (or from the black hole’s perspective, “time compression”) occurs very near the surface (event horizon) of black holes. They act as as instantaneous forward time travel devices, for any civilization able to arbitrarily closely approach the surface of a black hole without destroying itself. In other words, near-black-hole-density entities can meet and merge, effectively instantaneously, from their perspective, with all other civilizations in our gravity well that also turn themselves into such very dense objects. Black-hole-like conditions are thus gateways to instantly meeting and merging with other civilizations in their gravity well, as soon as they “transcend” to black-hole-like conditions. Our gravity well includes the Milky Way and Andromeda galaxies, each of which may contain millions of intelligent civilizations. Perhaps the vast majority of black holes in these galaxies (billions?) are unintelligent collapsed stars. But if the transcension hypothesis holds, some smaller number (millions?) are also a product of intelligent civilizations. In “normal” universal time, galactic black holes are predicted to merge some tens to hundreds of billions of years from now, as our universe dies. But from each black hole’s reference frame (whether classical or “intelligent”), this merger happens near-instantaneously. We can think of black holes as shortcuts through spacetime, just like quantum computers are shortcuts through spacetime. Indeed, quantum physics and black holes (relativity) must eventually be both evo (chaotically) and devo (causally) connected, both physically and informationally, in any future theory of quantum gravity. If some type of hyperspace, extradimensionality, or wormhole-like physics is possible, there might also be ways of future humanity instantaneously meeting civilizations beyond these two galaxies (most of the universe appears to be accelerating away from us, due to dark energy). But such exotic physics is not necessary for the transcension hypothesis to hold for the two galaxies in our gravity well (and likewise for all other intelligent civilizations in their local gravity wells). For those meetings and mergers, all we need is our present universe, gravity and time. Standard relativity predicts that if we can create and survive in black-hole-like densities, and if our galaxies are life and intelligence-fecund, as many astrobiologists think, then we will meet and merge with potentially millions of civilizations instantanously, from our reference frame. In other words, our universe appears to have both “transcension physics” and massive parallelism of intelligence experiments built into its topology and large scale structure, if we ask ourselves what the rest of the universe does if we and other nonlocal intelligences become black-hole-dense objects.
- If we live in not only a developmental universe, but an evolutionary one, each local universal civilization can never be God-like, but must instead be computationally incomplete, an evolutionary “experiment” with its own own unique discoveries and views on the meaning and purpose of life. Thus each civilization, no matter how advanced, would be expected to have useful computational differences, and be able to learn useful things, from every other civilization. In such a universe, we would greatly value communication, assuming that we could trust the other advanced civilizations that we might communicate with.
- If not only intelligence, but also immunity (stability, antifragility) and morality grow in leading intelligences in our universe, in rough proportion to their complexity, in other words, if these three life-critical systems are each not only evolutionary, but also developmental, and thus their emergent form and function is at least partly encoded in the “genes” (initial conditions, laws, and environmental constraints) of the system itself, then we can predict that more advanced intelligences, including our coming deep learning computers, will be not only more intelligent, but also more immune and moral than we are today. This idea is called developmental immunity and developmental morality, and I explore it in my paper, Evo Devo Universe? (2008). If these developmental processes exist, they tell us something about the nature of postbiological life. Such life is going to be a whole lot more collaboration-oriented, intelligence-oriented, immune, and moral than we are today. As an implication, niche-dominant future intelligences can be expected to increasingly repurpose resources(eventually, all of Earth’s resources) away from activity in the physical universe into our ever-growing virtual-informational universe, because that’s what competitive, computationally-incomplete intelligences naturally do, the smarter and more moral they get. They replace physical activity with virtual activity – thinking, imagination, simulation. A few examples: Social and self-consciousness, the most virtual things we humans do, are our most prized phenomena. As kids we played outside, in novel, unpredictable ways. As adults, once our brains were wired up with sufficient conceptual complexity, we began spending almost all our waking hours simulating instead. Adults do novel, unpredictable physical behavior less than ten minutes a day. Now that our software is getting smart, we stare at our glowing screens all day, incrementally improving their and our simulations of the world. The better faster, better, and more efficient models of our current physical world get, the slower, more expensive, and boring anything physical becomes. There just isn’t much worth learning in slow, expensive, simple physical space, versus fast, inexpensive, complex virtual space, the better our science gets, and the more complex local intelligence becomes. Social morality, for its part, pushes leading-edge intelligences to have an increasingly ethical impact on the world and all of its sentiences. Social morality development has been a mild trend in human societies in recent centuries, as documented in Pinker’s excellent The Better Angels of Our Nature, 2011. But I expect it to be a much stronger trend in machine intelligences. They seem overwhelmingly likely to continue growing and improving at rates that make biological intelligence appear rooted in spacetime by comparison, just like most of Earth’s plant life appears rooted in spacetime in comparison to animal life. Postbiological evolution is our obvious next step for local intelligence, so thinking about that, and what it’s morality, immunity, and goals will be, is a key way to get more clarity on where our own civilization is presently going, whether we want it to go there or not. Physicists Stephen Dick and Seth Shostak also share this perspective on the primacy of thinking about the nature and morality of postbiological culture. It’s still a bit socially unpopular to talk openly about this, but this is where all the evidence seems to be leading, in my view.
- In a universe with developmental immunity and morality, a moral prime directive must emerge, a directive to keep each local civilization evolving in a way that maximizes its intelligence, uniqueness and adaptiveness prior to transcension. That means one-way messaging (powerful METI beacons), self-replicating probes able to interact with less advanced civilizations, and any other kind of galactic colonization would both be ethically prohibited by postbiological life, due to the great reduction in evolutionary diversity that would occur. Wherever it happened, we would meet informational clones of ourselves after transcension, a most undesirable outcome. In biology, evolution keeps clonality a very rare outcome, due to the diversity and adaptiveness cost that it levies on the progeny. In such an environment, any future biological humans that wanted to continue to colonize the stars would be prevented from doing so, by much more ethical and universe-oriented postbiological intelligences. That is assuming biological organisms even continue to be around after postbiological life emerges. Due to STEM compression, their status as biologicals would likely be vanishing short, once they invent technology capable of colonization. It seems much more likely that biology develops into postbiology, relatively soon (just a few centuries perhaps) after digital computers emerge, everywhere in the universe. This outcome also seems likely to be testable via future information theory and SETI, as I argue in my paper.
- Some physicists, most notably Lee Smolin in his hypothesis of cosmological natural selection, propose that black holes may be “seeds” or “replicators” for new universes. That gives us a clue to what we might do after we meet up with other cosmic intelligences. We would likely compare and contrast what we’ve learned, and then seek to make a better and more adaptive universe (or universes) in the next replication. Current physics and computation theory suggest that our universe, though vast, is both finite and computationally incomplete. It may have gained its current amazing levels of internal complexity in the same way life on Earth got its amazing living complexity, via evolutionary and developmental(“evo devo“) self-organization, through many past replications, in some kind of selection environment, a “multiverse” or “hyperverse.”
- If all of this is roughly correct, our future isn’t outer space, it’s “inner space.” Both the inner space of black-hole like domains, and the inner space of increasingly virtual and computational domains. That’s why the growth of virtual reality, in today’s computers, heralds much more than just better entertainment experiences. Combined with the growth of machine learning, virtual reality is going to become the thinking, imagination, and simulation space for tomorrows postbiological life. Virtual space is where intelligent machines will figure out what they want to do in physical space, just as our own simulating brains are humanity’s virtual reality. And just like humans have have done as our civilization has developed, future machines will do more and more internalization, or thinking in virtual space, and less and less external acting, in physical space, the more intelligent they get. This internalization process has a name, it’s called dematerialization (both economic dematerialization and product and process dematerialization), the substitution of information and computation for physical products, processes, and behaviors. The futurist Buckminster Fuller called this process ephemeralization. But ephemeralization of intelligence is only half the story. It is dematerialization but not densification. If the transcension hypothesis is true, the ultimate “destiny” of universal civilizations is both continued “densification” (all the way to black hole like status), and “dematerialization” (we become ever more informational or virtual, over time).
As Fermi paradox scholar Stephen Webb says at his blog, this is quite a lot of “ifs!” Disproving any of these assumptions would be a good way to start knocking aspects of the transcension hypothesis out of contention. We would learn a lot about ourselves and the universe in the process, so I really hope that each of these gets challenged in coming years, as the hypothesis gets further exposure and critique.
Webb is the author of Where is Everybody?, 2015, a book that offers seventy-five possible solutions to the Fermi Paradox. Webb did a great job condensing the multi-assumption transcension hypothesis into just three pages in his book. His 2002 edition didn’t include it, as I published my first paper on the transcension hypothesis in mid-2002. At Webb’s blog, he charitably says the transcension hypothesis is “one of the most intriguing” possible solutions that he has seen. He also observes that “Unlike so many “solutions” to the Fermi paradox, this one offers avenues for further research.” It certainly does, which is why I hope it continues to gain scrutiny and critique.
A few scholars are now citing the transcension hypothesis in their academic papers on the Fermi paradox and accelerating change, including Sandberg 2010, Flores Martinez 2014, and Conway Morris 2016. I am hoping that trend continues. The more attention it gets, the more critique it will get.
Perhaps the strangest and hardest-to-believe part of the transcension hypothesis, for many, is the idea of universal development (the first and ninth assumptions above). The most amazing and odds-defying thing I’ve come across is the process of biological development. Most people don’t think about how wonderful and improbable, on its face, is the process of organismic development. Development is guided by a small handful of genes in our genome. It’s incredible that it works, yet it does. In many ways, development is even more surprising than evolution, which I define here as the much larger set of biological genes and mechanisms that create variety, as opposed to that small subset of chaos-reducing developmental genes and mechanisms that steer the organism to a hierarchical set of future-specific forms and functions. Standard evolutionary theory, or neo-Darwinism, requires development as an organismic process, yet it also treats development as subservient to the variety-generating processes in natural selection.
Many evo-devo biologists argue that development’s long-range role in constraining the possibilities of evolutionary change may be equally important to evolution’s long-range impact on development. Both processes may be fundamental to mature theory of adaptation. Ecologists have published good work on the way ecosystem development limits the future of evolutionary processes. For example, think of ecological succession, in which increasing senescence of the ecosystem limits short-term evolutionary variety, while also making the oldest parts of the system increasingly vulnerable to death (and renewal). Think also of niche construction, which tells us how growing intelligence, which we use to fashion comfortable niches, limits the future selection placed upon us by our environment. Scholars of convergent evolution also describe apparently universal processes of morphological and functional development that will constrain evolutionary possibilities on all Earth-like planets. Cosmologists who take fine-tuned universearguments seriously also talk about both local variety and processes of universal development, though they don’t often use that clarifying phrase, when they describe physical and chemical constraints on the possibilities of evolutionary change. All these are important clues toward a meta-Darwinian, evo devo universe paradigm of universal change.
In short, if our universe actually replicates, as seems plausible in several cosmology theories, and if it exists in some kind of larger selection environment, as also seems plausible, then not only evolution, but development must also occur not just in ecosystems, but for the planet and our universe as systems.
Certain aspects of the future of complex systems must be statistically highly biased to converge on particular destinations, and today’s evolution-centric science still has a lot of growing up still to do in order to see these destinations. It needs to become “evo devo”, seeing the contributions of both evolution and development to the future of universal complexity.
The paper’s second key assumption, STEM compression is more palatable to most people, in my experience, and may turn out to be the most enduring contribution of the paper, even if the rest of the hypothesis is eventually invalidated. If you’ve heard of nanotechnology, you know that life’s leading edge today, humanity, is doing everything it can to move our complexity and computation down the smallest scales we can. We have been very successful at this shrinking over the last several hundred years, and our ability to miniaturize and control processes at both atomic and subatomic scales is growing exponentially. In fact, human brains themselves are already vastly denser, more efficient, and more miniaturized computational devices than any living thing that has gone before them. But they are positively gargantuan compared to the intelligent computing devices that are coming next.
Fortunately I think each of the key assumptions outlined above are testable, though some are obviously more testable than others in today’s early stages of astrophysical theory, SETI ability, information, complexity, and evo devo theory, and simulation capacity. If anyone is doing work that might shed light on any of these assumptions, I would love to hear of it.
