Anticipating Our First Encounter with Advanced Extraterrestrial Life

20150211110221-9

This blogger, Pericles21, let go of earth-focused restraints to muse on a recent web article on the subject of what we might expect when advanced extraterrestrial life is 'discovered': 'New Advances in the Search for Extraterrestrial Life --Will It Be Inconceivable to Us?, (DailyGalaxy, August 8, 2015).

First, 'when ET is discovered' is such an ego-centered frailty of humankind. For self-protection (i.e., to prevent arrogant, and dangerous, presumptions of our superiority), we should shift our frame from humans 'discovering' ET to a reality that, indeed, it is us humans that will be 'discovered'... by a far more advanced life-form. This reframing will be necessary since it is ET who will have the advanced technology to visit us while we will not have the technology to return the courtesy (as far as the public knows).

The Daily Galaxy begins by framing their article using earth as a reference point:

A thin layer near the surface of Earth is teeming with life of huge diversity: from micro-organisms to plants and animals, and even intelligent species. Up to now, this forms the only known sample of life in the Universe. We now readily accept that the laws and concepts of physics and chemistry apply throughout the cosmos. Is there a general biology as well: is there life beyond Earth?

With the Sun just about half-way through its life-time, humankind as we know it is likely to constitute a rather short transient episode, and advanced extra-terrestrial life might be inconceivable to us in its complexity, just as human life is to amoebae.

As the article points out, the wide range of biodiversity here on earth that produces new species 'discoveries' every year suggests we should be prepared for a surprise when we 'find' ET because ET will have had many-fold more time-cycles of their evolution to produce a hugely wider variation of ET life forms than we have on earth.

But to be balanced in perspective, there is the contra-diversity theory of "convergent evolution" championed by Simon Morris (The Runes Of Evolution)(2015) that posits ET will probably look like us at least in basic morphology (number of limbs, eyes, etc). Professor Morris makes the case for a:

ubiquitous "map of life" that governs the way in which all living things develop.
It builds on the established principle of convergent evolution, a widely-supported theory -- although one still disputed by some biologists -- that different species will independently evolve similar features.

Pericles21 partially, but significantly, disagrees with the 'convergent' view of evolution and posits an 'interpreted diversity of life' point of view that:

although advanced extraterrestrial life may evolve towards a similar morphology (shape), advanced ET life will likely show us an immense diversity of function and internal life-chemistry that will not necessarily be 'bio-organic' ... nor human in appearance.

This will be addressed later.

To help us prepare to meet diversity in ET life, we must adapt our understanding of what is life. This definition has to be 'Reductionist':

how do/can we identify the most simple, basic features that might describe what is 'life'.

Pericles21 posits that first, there should be 'containment', then 'form', an 'energy gathering-utilization mechanism' (e.g., bio-ingestion, radiation absorption, temperature/density gradient, etc), a charge transfer-based sensory network serving to operate a potential energy machine, an information/sentience system analogous in function to DNA, and a mechanism to assure longevity or survival of the sentient unit or community.

From these proposed principles of life, one hypothetical example of ET "life" might derive from the recently announced (DARPA project) nanoscale, Nernst-reversible, metallic-dendritic growth-retraction mechanism that looks to be a solid state analogy to bio-neuronic network components (axions). This suggests a model of low temperature, quasi-solid, metallic-based ET 'life' with cognitive reflexes thousands of times faster than the human brain.

Pericles21 champions a personal, entropic theory of shape that:

evolution is driven to minimize entropy, i.e., to take a shape that is the most streamlined (least entropy)

This least entropic state, this evolutionary 'end-point', may take the appearance of shapelessness, where the highest evolved morphology will appear to be a 'spherical or globular form. But so far, we can only muse about ET since we have only one publicly known data point of life in the universe, our own planet Earth. We will have to wait to expand on evolution until a second data point is discovered or revealed. Then our knowledge, and science, of life will take a 'quantum leap'.

Stephen Hawking to Collaborate in Private Funded Search for Extraterrestrial Life

[Pericles21 submitted this piece in response to a request for comment at 'quora.com', July 22, 2015]

First, I feel it is good that Private Money will back the project because I expect Private Money will (potentially?) protect the project from non-scientific interference (belief orthodoxy and political pressures). Second, I feel there isn't a better project principal (designer/partner/adviser) than Stephen Hawking. His overall contributions can be 'earth changing'. should he let loose all his inner genius, i.e., the knowledge and intuition that lies within himself still unformed, unuttered. I hope to see exotic new concepts in astrophysics and astrobiology from Hawking, especially in the development and application of new mathematics formalisms and applications.

However, I am not wholly confident that Hawking personally is free from bias, i.e., I am made less confident of his objectivity by his openly (and frequently) stated warnings against naively reaching out and making contact with superior Aliens whose motives or psychology, in his words, 'might be harmful to humanity'.

(I don't fully share Hawking's apparent paranoia here.)

On the other hand, I hope the project will employ only passive detection methods and instruments, guided (and controlled) by a truly innovative search protocol with new design features for enhanced-performance detection instruments. In this context, I have full faith that Hawking's contribution to the project will be startling for the resulting protocol, improved instrumentation (in components and concept, i.e, #nano-scale-photometry) and results.

I pose the following topics for Mr Hawking to think on and develop or rule out:
- What kind of galaxy might have the greatest stability?
- How close to a central (massive) Black Hole might lie stable sol systems, dwarf galaxies and other space groups and bodies? How plentiful are Rogue Planets and rogue sol systems?
- What form(s) of energy (not currently conceived of on earth) might be used
by an advanced civilization? What might be the 'leakage' factor (radiation to space) for each? Would't an advanced civ develop 'non-leaking' energy?
- What other forms of detectable markers might there be other than energy and atmosphere? What markers miht not be detectable by current methods?
- Wouldn't a developed Alien disguise their civilization's location and state of advancement? How? Still, what markers might be leaked, detected and and deciphered?
- Wouldn't an advanced civ leave markers throughout it's home galaxy? What kind?
- What kind of 'code' might Aliens employ in their signals to 'externals'?
- Can 'entangled' communication be detected/hacked?
- What markers might hint at Alien tinkering with a Black Hole for energy tapping or signal modulation?
- Is it possible to develop (if not already) an advanced algorithm that might generate a matrix of possibilities, based on home planet astro-biological factors, for Alien features - language (yes!), mathematics, behavioral modes, ethics, cross-species prejudice and aggression, physical morphology, technology type...?
- What kinds of statistics might apply to this search? What new statistical tools or uses might be required?
- What kind of 'weaponry' might an Alien have? Personal? 'Battle craft'? Interstellar? Kinetic and/or energy?
- What form of energy intake might an advanced Alien require? Physical food? Abstracted energy (tablets, fluids devoid of origin identification)? Radiation?
- what morphology (or mix) might an Alien have? Physical? 'Gone cyber'?
- What might be Alien psychology types? What might be their significance to human safety?
- Overall, considering what we so far know about the distribution of 'habitable' planets, what radius segments might be best to search? I don't mean to seem uneducated about 'Habitable Zones' but what about non-water based life? Non-liquid based life (solid, gaseous, plasma, other states?)
- What innovative detection instruments might be developed? New wavelengths? New electronics? New modulation detection schemas - i.e., Alien Fourier signals, new algorithmic mixes, innovative exo-math series groupings, etc?
- How far might Alien employment of math series go? 5th or 6th order? 10th or above? What other radiative/dimensional relationships (ala Maxwell-Gauss) might Aliens have?
- How valid might be earth-based manifold theory applied to Alien technology? How might maths for 'extra-earth level' manifolds be formatted, codified and utilized?
- When in advanced tech might an Alien develop extra-Newtonian space propulsion? Beyond plasma? Space warping? Black Hole hopping? What signs might there be of Black Hole manipulation/control for inter-galaxy travel?

These are just some ideas.
