Planetary Atmospheric Pressure

Planetary Atmospheric Pressure

The media often overlook how many things have to be “right” for life to exist on a planet. Planetary atmospheric pressure is one factor.

By “life,” we mean the standard textbook definition of organisms that can move, breathe, respond to outside stimuli, and reproduce. The problem is that many conditions make other terrestrial planets (planets with hard surfaces) unlikely to harbor life. Life is even less likely on Jovian planets that are primarily gaseous. You can postulate balloon-like living organisms in Jupiter or Saturn’s atmosphere, but radiation and electrical problems make that unlikely as well.

Planetary atmospheric pressure depends on the weight of the gases above a planet’s surface. The air pressure on Earth’s surface is 14.696 pounds per square inch a sea level. That pressure allows water to exist as a liquid, and it will enable various gases to dissolve in the water. We all know what happens when you shake a bottle of carbonated beverage and then quickly remove the cap. The sudden drop in pressure causes an explosion as the dissolved carbon dioxide escapes from the liquid. For organisms to absorb oxygen dissolved in water, which fish do, the atmospheric pressure must be high enough for the oxygen to dissolve. The atmospheric pressure on the surface of Mars is .01 of the pressure on Earth. That means water on Mars would contain no oxygen or dissolved gases.

There has been discussion about finding water on the Moon or Mercury, but those atmospheric pressures are considerably lower than those on Mars. That means water would not be in a liquid state. On the other end of the pressure spectrum is Venus, where atmospheric pressure 92 times greater than on Earth. At that pressure, toxic gases would be dissolved in any water that existed on the planet.

Planetary atmospheric pressure is just one more variable that must be carefully and precisely chosen when constructing an environment that will support and sustain life. The creation is far more complicated than most of us realize. As we learn more, we must stand in awe of the God who created our planet.

Outer Space Is Not Dark

Outer Space Is Not Dark
Crab Nebula

Every time we get a better view of outer space, a new mystery steps forward. In 2015 a spacecraft called New Horizons went past Pluto and raced into outer space. The computers onboard the spacecraft were programmed to block out all light from known objects in the Milky Way galaxy. You would expect that if no light from stars or galaxies could get into the light measuring devices on New Horizons, it would measure only total and complete darkness. Instead, what New Horizons told us is that outer space is not dark but incredibly brilliant.

Outer space has an amount of light equivalent to the light from all the known galaxies in space! Tod Lauer, a spokesperson for the National Optical-Infrared Astronomy Research Laboratory in Tucson, says, “There’s something out there unknown.” The most likely scenario for this unexplained light is that there are still more galaxies and stars or clusters of stars beyond the reach of our telescopes, illuminating the distant clouds of matter.

Astronomers have said that the size of the cosmos is not only larger than we can describe with our known science and mathematics, but it is also larger than we can imagine. David wrote in Psalms 139:7-12, “Where can I go from your Spirit? Where can I flee from your presence? If I go up to the heavens, you are there. If I make my bed in the depths, you are there. … If I say ‘Surely the darkness will hide me, and the light become night around me,’ even the darkness will not be dark to you, the night will shine like the day, for darkness is as light to you…”

There is so much about outer space that we don’t know, like why outer space is not dark. But everything we discover points to the work of the Creator. It shows that He is a being outside of time and space who has created the cosmos with power and wisdom beyond our feeble ability to understand.

Why Do We Need Mountains?

Why Do We Need Mountains?

A skeptic recently complained that mountains are a mistake. “They block travel, cause avalanches, create deserts, and are just a general nuisance. If God were the creator, He wouldn’t have made these huge obstacles to human well-being.” In response to this skeptic, we consider, “Why do we need mountains?” For one thing, mountains are a very practical solution to one of humanity’s greatest needs–water.

In a basic geography or meteorology class, we learn about orographic uplift and rain shadows. As air comes across a flat area, it picks up moisture. But to make rain, there must be more than just water. Condensation requires a cool enough temperature and nuclei on which the water vapor can condense. Mountains provide both the cooler temperatures and the condensation nuclei.

As air pushes up the side of a mountain, it cools, and stirred-up dust provides condensation nuclei. For that reason, it is frequently very rainy on the windward side of the mountain. On the other side, the air is dry because all of the moisture has been removed.

Mountains can also capture and store water as ice and snow. Scientific American (January 2021) published an article with data on how many people get their water from the mountains. There are 78 regional mountain chains or “water towers” that deliver water to almost two billion people and surrounding ecosystems. Without mountains, the amount of land that would be hospitable to humans would be much more limited.

In addition to mountains capturing and storing water, they have also created underground aquifers. Glaciers generated in mountain areas have carved out huge valleys, depositing sand and gravel in permeable layers that allow massive amounts of water to seep into the ground. Here in southern Michigan, continental glaciers produced aquifers that supply us with water. In a large area of the Midwest United States, an underground aquifer called the Teays River has supplied adequate water for agriculture.

God has provided a massive and effective water system for nearly all continents, primarily because of mountains. Why do we need mountains? We need them for the water that allows irrigation as well as drinking and other uses. Mountains are beautiful, they provide recreational activities for humans, and they literally water the world for human survival.

Twin Study in Space

Twin Study in Space

One of the most exciting experiments conducted on the Space Station has been the twin study in space. Mark and Scott Kelly are identical twins, and both are astronauts. Scott lived aboard the International Space Station for a year. Mark remained on Earth and lived his normal lifestyle. Both men took daily blood and urine samples so that scientists could evaluate any changes caused by living in space.

Life aboard the space station is very regimented and very different from Scott’s previous life on Earth. On the Space Station, fluids swelled around Scott’s upper body and head, his immune system worked overtime, and his metabolism was altered. Of greatest interest to scientists was that Scott’s genetic makeup – his DNA – had been damaged.

There are protective structures called “telomeres” at the ends of our chromosomes. These structures get shorter with age and put the person more at risk for age-related illnesses. In Scott’s case, the telomeres temporarily lengthened and then became shorter. This means that space flight could put the body at risk for age-related conditions such as heart disease and cancer.

In addition to the changes in the telomeres, there were other changes in Scott’s health. His eye shape changed, and his vision weakened. His cognitive speed also decreased. Scott’s risk of heart disease measurably increased.

What conclusion can we draw from the data of the twin study in space? First, the human body was designed for living on planet Earth. Even a small change in environmental characteristics can make genetic changes that can be detrimental to human health.

The experiment also shows useful facts about the human body. The effect of telomeres is interesting and may explain the changes in humans’ life expectancy in the past. The importance of taking care of the world in which we live is also apparent from this data. We can clearly see that God designed this planet for humans to live. We will have challenges if we start traveling great distances into space in the future.

Life Chemicals in Space

Life Chemicals in Space
Piece of the Murchison Meteorite

On September 28, 1969, a meteorite fell near Murchison, Victoria, Australia. When scientists studied the meteorite, they found amino acids, which are the basic building blocks of proteins. In 1971, researchers reported that the Murchison meteorite’s amino acids were primarily glycine. Recent studies of the comet 67P/Churyumov-Gerasimenko have also detected glycine. Other studies of space materials have revealed that nucleobases and sugars exist in outer space. These studies indicate that there are life chemicals in space, but it is essential to understand that these compounds are not life.

The media has used headlines to suggest that science has found life in outer space. That is not the case. We have learned that there are life chemicals in space, but not life. These compounds are the key components of DNA and RNA, and that means that if there is life elsewhere, it will be made of the same stuff that we are made of. Claims of exotic forms of life existing all over the cosmos are exaggerations and not supported by the evidence. However, it is possible that God has not limited life to planet Earth. To travel throughout the cosmos, we may need to use the life chemicals available in space.

When Jesus gave the Great Commission, He said to take the gospel to the “kosmos.” From that Greek word, we get the English word “cosmos.” Carl Sagan said, “The Cosmos is all that is or ever was or ever will be.” You can find “kosmos” used in Matthew 24:21 and 25:34 and Mark 14:9 and 16:15. The Greek word “aion” is used elsewhere in Matthew, Mark, and Luke when referring to a habitable planet.

Jesus said to preach the gospel to every creature wherever they can be found. If I were to meet a sentient alien life form that could understand my speech, I would want to tell them about Jesus Christ. Hearing Christ’s teaching and the wisdom and power of God would improve the existence of any being who heard it.

“Truth In Nature” by Don Betts

“Truth In Nature” by Don Betts

One of our readers wrote the following poem and sent it to us. We share it with you to show one person’s evaluation of this ministry. The title is “Truth in Nature” by Don Betts.

Does God Exist? Of course, He does!
My brother John says so.
He digs deep for evidence,
So you and I may know
That God in all His glory lives.
His sign is everywhere
Extant in oh, so many things,
Wonders made for us to share.

John’s compiled a Dandy List,
Designs in nature meant to be
Proof in things that now exist
In which God’s face we see.
The truth of His existence
Is everywhere we look,
And our hope lies in persistence
Worded in His Holy Book!


Yes, we can find truth in nature as we see God’s design.

Star of Bethlehem and the Planetary Conjunction

Star of Bethlehem and the Planetary Conjunction

People give many different explanations of what the ”wise men” saw that led them to the Christ child. (See Matthew 2:1-12.) One of those explanations says there was a planetary alignment in the constellation Virgo (the Virgin). Since the magi may have been Zoroaster astrologers, they knew Christ had been born and followed “the star.” There is no connection between the star of Bethlehem and a planetary conjunction.

This December 21, at the winter solstice, there is a conjunction of Jupiter and Saturn. If you go outside about an hour after sunset and look to the southwest, you will see that the two planets are separated by less than a minute of arc, even though they are hundreds of millions of miles apart. If your eyesight is not very good, they may look like one very bright star.

This planetary conjunction is an exciting astronomical event, but it is not a good explanation of the star of Bethlehem. Whatever the magi saw, it could not have been a celestial star. Herod could have seen a celestial star for himself and would have had no reason to question its appearance as Matthew 2:3-10 describes. He could have had his people follow the star to find Christ and kill him.

Matthew 2:9 tells us that the star “went before them until it came to rest over the place where the young child was.” The closest star to planet Earth, outside of the Sun, is Proxima Centauri, and it is 4.2 light-years away. No stars move that way, and a planetary alignment is not a star.

The Bible does not present the star of Bethlehem as a natural object but as a miraculous act of God. Anytime the Bible says something is a miracle, it becomes a matter of faith, not science. How Jesus rose from the grave is not something we can scientifically explain. You either accept it, or you reject it, but all attempts to explain it naturally fail–and there have been many.

The star of Bethlehem was a miracle to show God’s acceptance of the Gentiles and to give Mary and Joseph the resources to move to Egypt and avoid Herod’s infanticide. The star of Bethlehem was not a natural event, but today’s planetary conjunction is. As we said yesterday, today’s event is not an omen and has no religious importance, but it is a rare, predictable astronomical event.

Planetary Conjunction for the Winter Solstice

Planetary Conjunction for the Winter Solstice
Jupiter and Saturn will appear close together but they are hundreds of millions of miles apart.

If you have looked to the southwest just after sunset in the past month, you probably saw two bright stars that have been moving closer to each other. They are not stars. They are the planets Jupiter and Saturn, two of the brightest objects in the sky, reaching a planetary conjunction for the winter solstice.

In their orbits around the Sun, Jupiter and Saturn appear to pass each other about every 20 years. However, the last time they appeared this close was in 1623, just 13 years after Galileo first pointed his telescope into the night sky and discovered four moons of Jupiter and saw Saturn’s rings. On December 21, those two planets will appear only one-tenth of a degree apart. That is one-fifth the diameter of the full moon.

You can bet that there will be hucksters making connections between this very unusual astronomical event and the star of Bethlehem or various political events. This conjunction is not part of a doomsday scenario but a demonstration of the accuracy of scientific observation. We can predict planetary conjunctions or solar and lunar eclipses to the minute, which is not hard to do.

When I taught earth science using the Earth Science Curriculum Project, we did a lab where the students predicted an eclipse of the Sun. They predicted when it would begin, when it would reach totality, and when it would end. I tried to make this a school-wide event, and the principal permitted me to take all 1000 students onto the school lawn to witness the eclipse. We gave the students special glasses and set up our telescopes to observe the eclipse.

We told the students what was going to happen and when it would happen. When it started, and the sky got dark, dogs began to howl. Crescents appeared on the ground under the trees as the eclipse projected through spaces in the leaves. Even though we had told the students what would happen, some kids began crying and ran back into the building in fear.

Why do people lack trust in scientific information, whether it concerns an eclipse, planetary movements, climate change, or COVID-19? Science and the Bible are friends, and God has called us to look at the creation around us and learn from it. Proverbs 8, Romans 1:19-20, and Matthew 6:25-33 all remind us of science and faith’s symbiotic relationship.

Tomorrow we will consider this planetary conjunction and the star of Bethlehem.

Carbon Atom Design Makes Life Possible

Carbon Atom Design Makes Life Possible

The media seems to be constantly concerned about the harmful effects of our “carbon footprint.” That phrase refers to how much carbon we kick out into the world’s environment in our daily activities. With all the concern about carbon, it is easy to overlook the fact that the carbon atom design makes life possible and demonstrates God’s engineering wisdom.

The carbon atom is one of the lightest atoms in the periodic chart. The relative weight of the standard carbon atom is 12. Uranium, on the other hand, is 25 times heavier. Carbon’s low weight means that things made of carbon are relatively light. Other elements are structured like carbon, but their weights are much heavier. Silicon is twice as heavy, and germanium is six times as heavy.

The carbon atom design makes life possible. Carbon has six electrons, but they are carefully arranged, allowing carbon to have the properties essential to life. All atoms have electrons orbiting the nucleus at different energy levels as you move out from the nucleus. Scientists give these levels letter identifications because of the spectral lines they produce. In a chemistry book, you will see the letters s, p, d, and f used to describe the spectral lines for electron orbitals of all elements in the periodic chart. The d and f orbitals are incredibly complex, but for carbon with only six electrons, the structure is relatively simple.

Carbon has two electrons in the 1s orbital closest to the nucleus and two electrons in the 2s orbital. They orbit the nucleus in a circular path. The next level out from the carbon nucleus is the p orbital, where electrons move in a figure-eight path. Three energy paths are available for two electrons each, and they are at right angles to one another.

Since carbon has four of its six electrons in the first two orbitals, there are only two electrons in the p orbital. That means there are four available openings in the carbon atom’s p orbital, and it fills those spaces by sharing electrons with other elements. If carbon is bonded to hydrogen, which has only one electron in its first orbital, the two elements will share an electron. In that way, hydrogen has two electrons filling its first orbital, and carbon will have one more of the six it needs to fill its last orbital.

Carbon will have to combine with four hydrogen atoms to complete its p orbitals, and the result is methane (CH4). Oxygen has eight electrons, so it needs two electrons to fill its third orbital, and two oxygens will share electrons with one carbon atom giving us carbon dioxide (C02).

Organic chemistry is incredibly complex since many periodic chart elements can share electrons with carbon creating different organic chemicals. This complexity allows life to exist and makes possible all of the medicines and organic materials that are a part of our everyday life. Carbon atom design makes life possible because of the Creator’s engineering wisdom.

Seahorse Role Reversal

Seahorse Role Reversal

In most animal species, the female is the one who gives birth and cares for the young, but that is not always the case. One exception to that rule is the seahorse role reversal.

Females seahorses compete to secure a mate. The female is the leader in the courtship ritual, which involves an extended “dance.” After the ritual, the female will deposit her eggs in a pouch on the front of the male. The male fertilizes the eggs and keeps the embryo sea horses for as long as ten weeks.

At the end of that time, the male ejects the young with muscle contractions, pushing them out into the ocean to fend for themselves. There can be dozens or hundreds of tiny seahorses, depending on how big the male is. Sea horses live in dense seaweed, which supplies food and hides them from predators. Small fish such as seahorses are easy prey for many animals in the sea, so they need to reproduce in large numbers.

Besides the seahorse role reversal, there are other cases in the natural world where a male is the caregiver for offspring. Diversity is the answer to many needs of a balanced life system, and the male and female roles can be different depending on the needs of the ecosystem.

The more we learn of the natural world, the more examples we see of incredible design and planning which reflect God’s actions in preparing this planet for human life. We all have a role in protecting the diversity of living things God has placed in our care.
