The inverted U of closed biological systems

Many have been worried about the existential threats to humanity – asteroids, climate change and ignorant leaders. However, there could be a more systemic and possibly unavoidable threat as long as Earth and its inhabitants continue to be a closed system. It is difficult to hypothesize based on a single observation of the emergence of life in the universe but the theory of evolution appears unassailable. Just as the accepted big bang theory in cosmology that seems to explain a lot after the point of origination but not the event itself, evolution seems to explain most observed biological specimens and their interactions but not the origination of life itself.

The accepted principle of evolution – the survival of the fittest – seems to be fine-tuned to optimize in short horizons. This is understandable as the survival of a species depends on adaptation to the present conditions and not a set of forecasted and uncertain conditions in the future. Thus, evolution creates fitter biological entities in the short run. It has led to more complex entities over time, the reasons of which are less clear. It is possible that the process is driven by underlying laws of physics, that has an arrow of complexity in biological entities aligned with that of time. This may be a side effect of unilaterally increasing entropy in the universe.

Thus, biological entities on Earth have been increasing in complexity. However, more complex entities also seem more fragile – with single cell organisms showing highest level of robustness and the latest iteration in complexity, the human, showing the lowest. In the past, we see several cycles where catastrophic events eliminated complex entities and returned the system to a much simpler state, albeit with differing initial conditions. This implies two things – closed biological systems in steady state will create more and more complex specimens and unavoidable and random catastrophic events will wipe out the more complex members and return the system to a simpler state at regular intervals.

Closed biological systems, thus, may have an inverted U curve on complexity and that may repeat over time. Humans, arguably the most complex in the contemporary system, could be primed for extinction in any large event. What have not been observed in the past are self-destructive internally generated events that humans appear to be very capable of initiating. So, the probability of cataclysmic events now is a lot higher than the past.  The laws of physics may be driving complexity of entities in a closed system higher over time, the laws of nature may be building complex but more fragile systems over time and in the presence of a catastrophic event, internal or external, the most complex entities are removed returning the system to a simpler state with different initial conditions.

The Earth may be due for a reset. This could also provide an alternative explanation for the Fermi Paradox.

Weird stars and aliens

As astrophysicists find weird observations, the fallback position for an explanation appears to be the presence of aliens (1). It is about time, as green women have so far failed to show themselves in spite of the space agency's assertion that they would be found before 2020. So, it is important to speculate about the presence of aliens on anything one could not explain by status quo theories and expectations. What the "smart humans," appear to be missing is that civilizations that could run circles around nearby hydrogen furnace would be so technologically advanced that either they make contact or hide from the low life.

The inexplicable dimming and brightening of HD 139139 (1) do not appear to fit with what humans have found and know. Hence they argue there could be aliens there as the first instinctual reaction. Ego and ignorance have the same fingerprint for those harboring the former will never let go of what they thought they knew and those suffering from the latter will never ask questions. Such is the state of science that new entrants to the field shall be brainwashed to believe in what is "known," and trained to fit observations to the accepted theory. It will be anathematic to challenge the status quo as doctoral defenses, tenures, and even careers will be lost in the courtyard, surrounded by ivy walls.

The two axes, the desire to prove life exists elsewhere as proclaimed by those "in the know," and the requirement to fit data to theory (and not dream of a different theory), hold humanity back. As science deteriorates to a level of comedy and speculation, there are real costs to humanity. Sending a billion $ "dragonfly," to the famous moon of Saturn is not an accomplishment, just a revelation that technology has not advanced enough to delegate the source as lifeless. Shooting robots at planets and satellites is not really science, it is engineering gone bad.

It is an intellectual zoo. Most do not want to let go of a theory that is over a century old. And, they are surrounded by engineers, standing ready to prove anything that is hypothesized - aliens and all.

Water, water everywhere, but…


The recent drought in India that has resulted in one of the major cities, Chennai, effectively running out of water just as Cape Town did last year, is a cause for concern. The proposed solutions appear to focus on water availability and they are likely misguided. The blue planet has plenty of water, but it is brine. So, it is not lack of water that humans should focus on but rather how to remove salt and other impurities from this abundantly available resource on Earth.

Just like many other contemporary problems, this could also be solved by cheap energy. With an efficient Hydrogen furnace in close proximity, an advanced civilization would have reached technology that can emit zero cost energy. Unfortunately, humans are still clinging on to the concept of unearthing and burning highly toxic Carbon for their tactical needs. For humanity to advance, it has to set a goal on close to zero cost energy production as that will solve many problems threatening their very existence, including rising temperatures.

However, policy-makers and politicians are not sufficiently schooled on how the complex habitat react in non-linear ways and why feel-good actions are ineffective. For example, reducing greenhouse gas emissions from the current levels will have no measurable effect on outcomes. That window has been closed a long time ago. So, all the noise around policies and accords world over is just that, noise. Of course, it makes many feel good that they are doing “something.”

The more important thing to focus on is technology – how to terraform Earth back to its original condition. There are plenty of ideas available but it will take resources and a focus on research and development. And, R&D should move into exotic and untried options, not conventional ones to simply suck the bad stuff out and sequester it underneath. On a planet suffering from plate tectonics and idiotic human actions, it is unlikely that the bad stuff will stay down for long.

Advanced R&D is sorely needed not only to mend a broken planet but also to assure its inhabitants have life-giving fresh water forever.

Quantum pipe-dream

Quantum computing (1), possibly the only leap humans could take to reach many of their overblown expectations in Artificial Intelligence and elsewhere, is a pipe-dream. Humans are likely to find extra-terrestrial life before they will be able to parade sufficient number of q-bits to make practical computing. And, the ETs have been hiding so effectively from the space agency that they are unlikely to show up for many decades.

To make quantum computing possible, educational institutions need to redesign their curricula bottoms up. Spending years of learning Newtonian and even relativistic Physics does not lead to insights in the quantum world. The fact that most gravitate toward the "knowable," perhaps because of the ease of achieving doctoral degrees and tenures, does not mean that it is the right way to go. Meanwhile, they are building bigger and longer tunnels all around the world, smashing particles against each other to find new ones, listening to gravity waves by hanging mirrors and in their spare time, shooting robots at nearby planets and satellites to find the ever-elusive ETs. All of these activities are misguided. The latest theory postulates complete ignorance of humans and it is just that most do not want to think about it.

Humility could help humans reach the next stage. Backfilling darker matter and energy to hang onto to the contemporary faulty theories is symptomatic of the deterministic era. As the particle zoo grows faster than popping corn kernels in a popcorn maker and the water bodies way below the Earth's surface sit waiting for the particles that are unlikely to show up, humans have to admit ignorance.

It is time to wipe the slate clean and start-over. Initial conditions set a century ago may provide useful guidance.
