Close mind

Some people are so—

And I don’t know what the right answer is for each person: fearful, angry, arrogant, prideful, selfish, wrathful, whatever—

that as long as there is some infinitesimal escape, some nano-fractional percentage that allows them escape the material certainty of a higher power…

They will grab it and cower behind it.

These people commit to a profoundly irrational conspiracy-within-themselves to avoid, at all costs, the Father.

They have that right.

And their choice, strangled as it is, will be honored.

Phosphorus and Molybdenum Problems for Life on Other Worlds

Stymied by attempts to find life-friendly conditions on surfaces of extraterrestrial planets and moons, astrobiologists have turned to increasingly exotic sites. Two such sites are (1) the upper atmospheres of planets and moons with thick atmospheres and (2) possible pools of liquid water below the surfaces of planets and moons. A nearby example of the former are Venus’s high clouds. Nearby examples of the latter are Europa and Enceladus, moons of Jupiter and Saturn, respectively.

A recent paper published by astrophysicists Manasvi Lingam and Abraham Loeb in the Astronomical Journal casts doubt on the suitability for life in upper atmospheres and subsurface lakes or oceans.1 The paper explains how these sites are likely plagued with extreme shortages of phosphorus, molybdenum, and other life-essential elements.

What Life Requires

All conceivable carbon-based life-forms require the availability of both phosphorus and molybdenum. Phosphates are an essential component of DNA, RNA, ATP, and phospholipids. Molybdenum is essential for the functioning of several life-critical proteins2 and for animals it eliminates toxic reactions to sulfites in food.3

Four decades ago, biochemists discovered that any conceivable physical life-form must be carbon-based. Carbon is the only element in the periodic table that permits the chemical bonding diversity, complexity, and stability life molecules require.

Both phosphorus and molybdenum are relatively rare. Phosphorus comprises 1,050 parts per million by mass in Earth’s crust4 while molybdenum makes up just 1.2 parts per million.And yet Earth is extraordinarily rich in both of these elements. Compared to the rest of our galaxy and the universe Earth’s phosphorus to magnesium ratio is four times higher and its molybdenum to magnesium ratio is five times higher. Yet even with this great abundance of phosphorus and molybdenum, life productivity on Earth is limited by their availability.

Just-Right Phosphorus Abundances Needed

In their paper, Lingam and Loeb first cite research published a year ago6 that established that previous to 600 million years ago Earth’s abundance of oceanic phosphorus was less than a fifth of what it is today. What kept the phosphorus concentration so low was scavenging of phosphorus into ferrous minerals, absorption into iron oxides, and limited recycling in what was then an oxidant-poor ocean.

This paucity of phosphorus limited life in the oceans to microbes at an abundance and diversity level far below the present. What phosphorus existed in the oceans at that time came almost entirely from the runoff of rivers on the continental landmasses.

The Harvard astrophysicists then pointed out the obvious. Ice-covered worlds like Europa and Enceladus will not have any riverine input of phosphorus. Furthermore, the liquid water oceans that might exist below these worlds’ ice crusts very likely will have either a neutral or basic pH. A significant body of liquid water below a surface ice crust also implies the very high likelihood of hydrothermal activity at the bottom of the liquid water pool (see figure 1). Hydrothermal activity efficiently removes phosphorus from subterranean water pools.

Lingam and Loeb conservatively calculated that the abundance of phosphorus in subterranean oceans of ice-covered worlds will be 1,000 to 100,000 times lower than in Earth’s oceans. Such an extremely low abundance of phosphorus makes the survival of life, let alone the origin of life, a near impossibility.

Other Just-Right Mineral Abundances Needed

The researchers go on to address the availability of other life-essential elements in ice-covered worlds. They note that the only significant source of bioavailable nitrogen in ice-covered worlds will be submarine weathering. Though they were not able to produce a precise estimate of the amount of bioavailable nitrogen produced by such weathering, they conclude that it would be much below “the corresponding value for continental weathering by rain water.”

Next, Lingam and Loeb examine bioavailable iron. For Earth, virtually all the bioavailable iron in the oceans comes from eolian mineral dust, interplanetary dust, and subaerial continental weathering.8 None of these sources are available in subsurface ocean worlds. Thus, such worlds will lack not only the phosphorus abundance that life needs but also lack the nitrogen, iron, and possibly several other life-essential elements.

More Habitability Constraints

The pair of researchers did not address the problem of too much subsurface liquid water. If this water adds up to more than 1 percent of the mass fraction of a planet or large moon, the pressure from the water depth will form a thick, impenetrable ice layer on the ocean floor (see figure 2).9 For such worlds there will be no submarine weathering and, thus, no delivery of phosphorus, nitrogen, iron, copper, molybdenum, and other life-essential elements into the liquid water ocean.

Lingam and Loeb close their paper by considering the habitability of planets like Venus (see figure 3). For the past fifty years, astronomers have speculated that life could conceivably survive at those altitudes in the upper atmospheres of Venus-like planets where the temperatures would allow water to exist in the liquid state.10 However, neither the Galileo orbiter nor the Venus Express mission has found any evidence for molybdenum in Venus’s atmosphere.11 Without molybdenum and other bioessential trace elements life is not possible in the atmosphere of Venus or planets like it.

The researchers do not rule out life in subsurface ocean worlds or Venus-like planets, but they conclude it is unlikely. However, given the degree to which the availability of phosphorus, nitrogen, iron, and molybdenum limits life on Earth, the case must be far more constraining for the exotic sites. The evidence Lingam and Loeb provide for all these nutrients being orders of magnitude less abundant in subsurface ocean worlds (and if the ocean is deep, nonexistent) and Venus-like planets than on Earth causes me to question whether life can survive on such worlds.

Earth’s Just-Right Abundance Levels

Scientists already know that plants and animals cannot survive on so little phosphorus, nitrogen, iron, and molybdenum. Laboratory experiments can settle whether there is any possibility for long-term survival of microbes.

In the meantime, these Harvard astrophysicists give us yet more reasons to be grateful that we live on such an improbable planet. Our planetary home has the most anomalous abundances of elements, especially when it comes to vital poisons. Earth’s crust contains just-right abundance levels of all twenty-two vital poison elements.12 Vital poisons are elements that if too abundant will kill life, but if too under-abundant will also kill life. So much “just-rightness” points to a supernatural Creator who has a special love for human beings.

The Folly of Men and Spirits

Ignorance, arrogance, fear, hate, trauma and unbelief function in the human mind much like gravity does in a star.

The more of these vices you have, the more they are allowed to increase, your mind grows denser and denser, heavier and heavier, until every thought collapses under the weight of its own darkness.

And where the mind leads, the heart follows: a black hole in the soul.

Everything that enters such a cold cyclonic soul – logic, reason, science, hope, analytical fidelity, faith and even light – cannot escape.

The inestimable pressure of these vices eventually break all bonds of coherence – fairness, rationality, emotional stability, cause and effect, continuity of proofs, law of non-contradiction – until one is reduced to a babbling heap of relativism, a subjective hustler of legal and linguistic shell games that violate all logic, inference, deduction, induction, even math.

This is the inevitable result of turning your God-given free will against God who wills you to use it wisely.

The last phase of this collapse is always the same: calling evil good and good evil.

Angels died this death long before men did.

In time, all monsters are buried, but never in the same graveyard as their victims.

The Mountain of Souls

Atheists are fond of saying they have gotten rid of all the gods of history and that only one remains.

Like the majority of their pronouncements, they are backwards.

They have not arrived at the last god standing. They have arrived at the first one.

They just took a long circuitous route to get to Him.

All they did was clear away the demons.

Now, having chopped down all the trees—surprise!

There is a Mountain staring down at them.

Swing all you want, guys: your ax will never hurt so much stone.
