The Louvre in Paris is the largest art gallery museum in the world. The building began as a twelfth-century fortress and became a museum at the time of the French Revolution in the late eighteenth century.
Housed in the Louvre are some of the world’s most outstanding artworks, including the Mona Lisa. Visitors number over nine-million per year. If you visit the Louvre, you will be overwhelmed by the enormous building and the vast number of paintings and statues.
Similarly, as we look at the enormous universe around us, we are overwhelmed by the galaxies, stars, and planets–and the life we see on this planet. Rice Broocks, in his book “God’s Not Dead,” writes, “There is evidence for an intelligent Creator everywhere you look. To say that there is no evidence for this Creator is like saying the thousands of paintings in an art museum couldn’t have been painted because there are no artists visible in the gallery.”
Nobody would visit the Louvre and make such a ridiculous statement. How can anyone look at the amazingly complex universe and not recognize that they are seeing the largest art gallery displaying the work of the greatest Artist? Some examples are butterfly wings, colors, structural color, and beauty in Earth’s diversity. The largest art gallery in the universe is the universe.
One of the many things that make our planet uniquely well designed is the atmosphere. Our atmosphere has the right density to burn up the 10,000 plus meteors that speed into it every year. It’s also dense enough to scatter the cosmic rays and X-rays from space, so we are protected from this deadly radiation by our Earth’s atmospheric design.
Also very important, the atmosphere is thin enough to allow light to penetrate so plants can grow. It contains the proper mix of gasses for all living things to use. There is enough oxygen for us to breathe, but not enough to cause dangerous, uncontrolled combustion. It has the right amount of carbon dioxide to allow plants to live and give us the right amount of the “greenhouse effect.” This proper amount prevents too much heat from radiating off into space, keeping Earth at a temperature that promotes life.
The atmosphere is mostly nitrogen, which is relatively inert, but plants need it to grow. Because nitrogen is inert, it’s released to the soil by bacteria and certain plants, such as legumes or by lightning or tectonic activity. The atmosphere is topped off with a layer of ozone that absorbs ultraviolet energy from the Sun to keep us from being overexposed to the harmful effects of UV rays.
Modern technology has given all of us a chance to look through a telescope and see what is in outer space. In the “old days” the only people that could look outside our solar system were astronomers who had access to powerful telescopes. Now all of us can look out and see what lies beyond our solar system without buying a telescope because the pictures are available to us on the web. If you go to apod.nasa.gov you can see pictures taken through the world’s largest telescopes. The picture for August 7, 2020, is of the Pipe Nebula. As I stare at the picture, I am awestruck by the number of stars in the cosmos.
Why are there so many? Why is the cosmos so big? If you believe that God created it all, why did He create billions of stars in billions of galaxies? If Earth is the only place with life, why are there other planets, other stars, other solar systems? Why is space full of matter like the Pipe Nebula? Obviously no one knows the answers to all these questions. Anyone who gives a dogmatic answer that invalidates the existence of God is claiming to have more knowledge than the rest of us. Those who claim the pictures are fakes or artistic works have not taken the trouble to go to an observatory and look through a telescope. Most observatories have arrangements that allow the general public to do that. We have no excuse for doubting the credibility of the pictures.
Whether you are an atheist or a religious fundamentalist, your viewpoint makes massive assumptions. Here are a few things you should know, that may make you uncomfortable:
No observation made has ever challenged the basic biblical claim that there was a beginning and that it was caused. You can argue about what the cause was, but attempting to deny that there was a beginning, puts you at odds with the observations and the laws of physics–even at a quantum level.
There is no support for the assumption that planet Earth is the only place in the universe where life exists.If there is life elsewhere, God created it, and the Bible does not say the Earth is the only place where God created life. However, the distances are so huge that we will never know if this is the only place–at least not in our lifetimes. Many years ago, I debated an atheist on a talk show with Larry King. A listener called in and asked the atheist and me “What would you two do if a space ship landed in plain sight and a little green man got out and asked, ‘Has Jesus been here yet?’” That raises all kinds of issues, but it makes the point. By the way, the atheist’s answer was, “Punt.”
As we look through a telescope we are looking into the distant past light-years ago. No one knows what the distant future holds. Could it be that God wants humans to colonize the cosmos? Perhaps our vision of God’s kingdom is too small. Every time I look at one of those pictures of star fields or look through a telescope, I am reminded of Psalms 8:3-4 “When I consider the heavens, the work of your fingers, the moon and the stars which you have ordained: What is man, that you are mindful of him?”
An amazing fact is that the creation is designed for continually spreading life throughout the Earth. That isn’t always a good thing for humans.
Several years ago, a friend of mine built a large pond on his farm. He planned to stock the pond with desirable fish, avoiding carp and sunfish, which he considered to be trash fish. He stocked it with largemouth bass, and some minnows used as food for the bass. Later, when I was visiting him, I decided to do a little fishing in his pond. The first fish I caught was a large carp, and a whole school of sunfish converged on a grasshopper or worm I used as bait.
My friend was horrified and promptly wanted to accuse an enemy of putting trash fish in his pond. I noticed a great blue heron wading through the shallows of the pond picking off minnows, and immediately I knew how the sunfish got there. Herons wade through areas where fish have built nests of eggs during their spawn. The eggs are sticky and adhere to the Heron’s legs. When the Heron goes to another pond, it carries the fish eggs along.
Recent research has discovered another way in which fish are designed to spread from place to place. A study in Hungary has shown that some fish eggs can pass through the digestive system of a duck, and a small percentage of the eggs have baby fish still alive inside.
The wisdom of this system in the natural world is apparent. A new body of water will usually be sterile. To get a functional ecological system going, the bottom of the food chain must be established quickly. Birds are facilitators in getting a fish population in operation, and now we know of at least two ways they do it.
The implications for humans are significant. Biologists trying to keep a species of carp out of the Great Lakes have a huge problem. The design of fish and birds makes it almost impossible to keep any fish population isolated. God has created many designs for spreading life throughout the Earth, even into sterile places.
Burning a Rainforest to Plant a Palm Oil Plantation
One of the interesting aspects of the story of Adam and Eve is the environment in which God placed them. Genesis 2:8 tells us that God planted a garden, and verse 9 tells us that He planted every tree that was pleasant and good for food. The Bible doesn’t say how long God took to plant the garden and what was involved in the garden’s growth. Verse 15 tells us that “God took the man and put him into the garden of Eden to dress it and to keep it.” After establishing the man’s environment, the Genesis account turns to man’s spiritual nature. But the planted garden with every tree is our focus here as we think about deforestation and disease.
The Bible describes the first humans as what anthropologists call gatherers. Agriculture was a long way off. The eating of animals isn’t even suggested until chapter 4 when Abel brings “the firstlings of his flock” as an offering to God. An article in Scientific American (June 2020, page 8) points out how modern agricultural methods have led to the three major highly infectious viruses since 2002 – SARS, EBOLA, and COVID-19.
Slashing and burning to create land for crops, such as palm oil, reduces biodiversity and puts humans in contact with wildlife that carry microbes able to kill us. Species that survive the clearing are more likely to host illnesses that can be transferred to humans. In addition to the three main viruses of our time, the Scientific American article mentions some other diseases have come from rain forest inhabitants – Zika, Nipah, malaria, cholera, and HIV.
Humans have brought on most of our major disease issues by allowing greed and “survival of the fittest” mentality to govern our decisions about how we use the environment. We waste between 30 and 40% of the food we produce. Poor agricultural techniques and mismanagement of water prevent efficient use of what God has given us. Deforestation and disease go together. Now we are contaminating our atmosphere and filling our lakes, rivers, and oceans with waste.
The dominant theory for the origin of the planets in our solar system assumes that they all evolved from a single mass or nebula. Several factors support that idea. Those factors include the fact that the planets lie roughly in one plane, that they all revolve around the Sun in the same direction, and that there is mathematical predictability to their location. Most of the irregularities that might indicate against a common source, such as variations in planetary tilt, have reasonable explanations. However, new planetary atmosphere variations are difficult to explain.
Recent studies of the atmospheres of the terrestrial planets have shown wide variations. Our atmosphere contains 78% nitrogen, but nitrogen on Venus is 4%, and on Mars, it is 2.7%. Both Mars and Venus have atmospheres that are 95% carbon dioxide, while Earth is 0.1%, and Mercury has none. Earth and Mercury have oxygen in their atmospheres, 21% and 42% respectively, but Venus and Mars have less than 1%. Astronomers theorize that they can explain these planetary atmosphere variations. They suggest that the atmospheres are not original to the planets, but were produced by processes that took place after the formation of the planets. The best guess now is that impacts and outgassing formed the atmospheres. This is not a trivial matter because life is not possible without the proper combination of atmospheric gases.
The Genesis account describes the production of Earth’s structure in a sequence. Genesis 1:6-9 indicates separate creations of the hydrosphere, atmosphere, and lithosphere. The new data support the idea that once Earth was created, continued activity prepared it for life. Once again, we find the scientific evidence in support of the Bible’s description.
Lava tubes on Earth are dark and cold places. It’s unclear what they may be like on Mars, but perhaps someone will find out. Future Martian explorers may experience life in a lava tube.
Camping out on Mars is not a good idea. There is no breathable atmosphere, and the radiation is deadly. Without much of an atmosphere, the temperature on Mars varies extremely. On a summer day near the equator, the temperature may reach a comfortable 70 degrees F (20 degrees C). However, without the thermal blanket of an atmosphere, the night-time temperature can drop to minus 100 degrees F (minus 73 C). At the poles, the temperature can get down to minus 195 F (minus 125 C). The average temperature on Mars is minus 80 degrees F (minus 60 C).
Transporting materials to build a suitable shelter on Mars would be difficult. Any structure would have to be small and still might not give adequate protection from radiation. The surface of Mars receives unfiltered solar radiation, cosmic rays, and ionized particles from the solar wind. With the lack of an atmosphere or a magnetosphere, which we have on Earth, there is nothing to block the dangerous radiation. The amount of radiation is many times what astronauts experience in the International Space Station (ISS). NASA limits astronaut exposures in the ISS to months. Explorers might have to spend years on Mars. Just getting there will take about seven months.
What does this have to do with life in a lava tube, and what are lava tubes anyway? During a volcanic eruption, molten lava can bore its way through the ground and run out into the open. When the molten lava exits, it often leaves behind a cave-like underground tube. I explored the Lava River Cave (bottom picture) in Arizona, located in the Coconino National Forest. The walls are black basalt, which the lava left behind, and there is no light except at the entrance. The temperature remains constant at around 40 degrees F (4 degrees C). In most places, the ceiling is high enough that I could stand up, but in other areas, I had to crouch down or get on my hands and knees. The top picture shows a larger lava tube in Iceland.
Researchers have detected what appears to be lava tubes on Mars near Hadriacus Mons, which is a volcanic mountain formed long ago when the Martian interior was hot. They suggest that those lava tubes would be the best location for a Martian outpost. The lava tubes would give protection from the radiation, and it might even be possible to seal one off, pressurize it with oxygen, and heat it. They tested the radiation protection concept in some lava tubes on Earth, including the Lava River Cave in Arizona.
All of this drives home how blessed we are to have a home on planet Earth. I can step outside on a beautiful day, breathe the oxygen, feel the filtered rays of sun on my face, enjoy the pleasant temperature, and thank God for the blessings. Stepping out of the lava tube on Mars without the protection of a super-spacesuit would mean instant death. Even though I enjoyed exploring the lava tube in Arizona, I wouldn’t want to live there. Life in a lava tube does not interest me. I enjoy living on this planet, which God designed to give us everything we need if we will just take care of it.
The ancient Greeks saw the five visible planets and called them “wandering stars” because they moved randomly across the sky instead of staying in fixed positions like the stars. The word “planet” comes from the Greek word for “wanderer.”
We have known for many centuries that the planets are not stars. They appear to wander because they orbit the Sun, just like our planet Earth. They orbit at different speeds, making them appear to wander in the sky. For astronomers to classify a celestial body as a planet, it must meet three requirements:
It must have enough mass for gravity to cause it to become spherical, unlike an asteroid.
It must not have enough mass to cause thermonuclear fusion, which would make it a star.
It must have cleared the area of debris known as planetesimals.
We have five planets that are visible without the aid of telescopes or even binoculars. Two of the visible planets are called inferior planets, not because of importance but because their orbit is inside Earth’s orbit. They are Mercury and Venus. The other three are known as the superior planets since they are beyond Earth’s orbit. They are Mars, Jupiter, and Saturn.
There is one essential thing the ancient Greeks did not understand about the solar system. They did not know that it is orderly. The Greeks saw a pantheon of gods controlling various aspects of the Earth and skies. Each of their gods had all of the bad traits of humans struggling with each other. It was the Judeo-Christian concept of one almighty and wise creator God who created an orderly system that led to the scientific understanding of the cosmos.
Today, we can study and understand the wisdom of God in creation. Because of that, we can know where the planets and stars, as well as solar and lunar eclipses, will be visible at any given time and from any location on Earth. Those “wandering stars” are not wandering after all.
Measuring the distance to stars is not as hard as you might think. As an earth science teacher at Riley High School in South Bend, Indiana, I enjoyed seeing a student’s eyes light up when they came to understand some scientific fact. They had thought it was beyond them, and suddenly it made sense. Knowing the distance to a star was always one of those facts. Let me show you how easy it is:
Look at a picture on the other side of the room. Hold your finger in front of your face and close one eye. Line up your finger and the object on the wall. Now close that eye and open the other eye, Does your finger appear to jump? If you drew a line between your eyes and extended a line from each eye to the picture, you would have a triangle. The apex angle at the picture is controlled by how far away it is from you. If you do the same experiment with an object that is closer, there will be a different angle.
The illustration on the right shows the Earth making its yearly orbit around the Sun. A line from the Earth to the Sun will establish a triangle. In six months, it will look like objects at the apex angle have moved. How much they will have moved depends on how far away they are. My classes do simulations of these measurements on the football field, and it becomes apparent how easy measuring the distance to stars can be.
The measurement unit astronomers use is based on how far away a star must be for the angle at the apex to be one arcsecond. We call that distance one parsec, and it is 3.26 light-years. If the parallax angle is .5 seconds of arc, the star must be 6.52 light-years away. The smaller the angle, the farther away the object is. The European Space Agency’s Gaia mission, which has been underway since 2013, can measure the parallax angle to a millionth of a second of arc. Objects that move such a small amount are tens of thousands of light-years away.
The cosmos is much larger than most of us can imagine. The light we see from some of those stars left the stars hundreds of thousands of years ago. Measuring the distance to stars gives new meaning to passages like Isaiah 40:22: “He stretched out the heavens as a curtain and spread them out as a tent to dwell in.”
If it has taken the light from the stars God created many tens of thousands of years to get here, it is evident that the creation didn’t happen a few thousand years ago. Verses describing the process of creation are untimed and undated. Let us not allow human traditions to challenge the integrity of the Bible. God created time, and He certainly is not limited by anything He created.
People have paid much attention to the accumulation of greenhouse gases in our atmosphere because they play a significant role in global warming. The main culprit in the greenhouse gas list is carbon dioxide. Not only do we exhale this gas, but fires of all kinds produce it. With the recent major fires in Australia, there is even more concern about the amount of carbon dioxide in the atmosphere. But God has given the Earth some tools to counteract greenhouse gases.
The most efficient tool built into the Earth is a microscopic plant called a diatom. There are 12,000 species of diatoms in Earth’s lakes and oceans. Unlike phytoplankton, diatoms are encased in porous, intricately structured silica shells. Examined under a microscope, these silica shells are beautiful, and they are very resistant to change in shape. That means that the spaces between the shells can collect particulate material. So diatoms are used as filtering agents to filter water for swimming pools and as fillers for aerating soils in yards. The shells are used as diatomaceous earth, which is familiar to most of us, especially those who raise roses or tomatoes.
Diatoms can also absorb gases. In the oceans, they absorb massive amounts of carbon dioxide and lock it up in the ocean’s depths. Diatoms capture as much carbon dioxide as all the trees, grasses, and other land plants combined. The fancy latticework of the diatom is not just for humans to admire. Because of the twists and turns of their shells, the surface area of diatoms is much greater than that of smooth shells. The increased surface area maximizes photosynthesis and allows the diatoms greater energy for growth and reproduction.
The life expectancy of a diatom is about six days. Because the silicon is heavy, the diatom at death sinks to the ocean floor or lake, taking carbon with it. One solution to the buildup of carbon dioxide is to catalyze the growth of diatoms. Iron nutrients can do that, and seeding the oceans with iron might be a way to reduce the amount of carbon dioxide in the atmosphere.
Diatoms are one more example of the design built into Earth’s structure to allow the planet to exist over the long haul. While diatoms are not apparent to the human eye, they are tools to counteract greenhouse gases and a possible solution to a modern problem.
