Spreading Life Throughout the Earth

Spreading Life Throughout the Earth - Great Blue Heron
Great Blue Heron

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.

Deforestation and Disease Pandemics

Deforestation and Disease Pandemics
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 title of the Scientific American article is “To Stop Pandemics, Stop Deforestation.” God gave us the “garden” and the tools to manage it. We can’t continue to mismanage it and not see more consequences such as pandemics, global warming, and diseases produced by our failure to do what God called us to do in the beginning.

Planetary Atmosphere Variations

Planetary Atmosphere Variations - Earth

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.

Time Debate and Genesis

Time Debate and Genesis

Several years ago, I was involved in a three-way debate in California between a Young Earth Creationist, a Modern Apologist Scholar, and myself. I was supposed to present design arguments while the other two engaged in an intellectual tug-of-war over the Genesis account. I learned from that experience not to get involved in that kind of time debate again.

I have engaged in debates with atheists for over 50 years, but those debates were easy to understand, and the different views were clear. This Califonia debate was between believers. Because the subject was the integrity of the Genesis account, I used a chart that shows that the SEQUENCE of the Genesis 1 account and the fossil record are identical. The Apologist Scholar denigrated my chart by saying that the events described occurred over a 600 million year period, and, therefore, the Genesis account could not be viewed as historically accurate. The Young Earth Creationist reacted to that claim, and they engaged in a free-for-all about the time issues and the purpose of Genesis 1. The point of my chart was lost in the time debate.

Humans always get hung up on the time issues. God created time. Psalms 90:4 says, “A thousand years in your sight are but as yesterday when it is past and as a watch in the night.” God is outside of time, and the Bible tells us over-and-over not to restrict Him by demanding a time-scale for what God does. “But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years and a thousand years as one day” (2 Peter 3:8). “It is not for you to know the times or the seasons, which the Father has put in His own power” (Acts 1:7).

The message of Genesis is not about time. The first verse of the Bible describes an event and process that is not dated or timed. The fact that the first chapter gives an accurate account of the SEQUENCE in which God created the Earth and all that is on it is excellent evidence that it came from the Creator. Since God created time, there is no reason for us to get hung up on how long God chose to do His work.

Theologians have led us down a rocky road of ascribing dates and times to the things God has done or will do. The birth of Christ certainly did not happen on December 25. Denominations have been created by theologians who try to establish when Christ will come again and when the judgment will take place. This is even though Jesus said, “…of that day and hour knows no man, no not the angels of heaven – only my Father” (Matthew 24:36).

People want to know when things will happen so that they can be prepared, but 2 Peter 3:11 anticipates that and warns us to always be prepared. It is hard for us to comprehend the fact that time for us ends when we die. It is equally difficult to realize that God acts outside of time. Many people stumble by putting the Genesis account at odds with the scientific evidence or relegating the Bible to symbolism and mythology rather than being literally true. Don’t get caught up in the time debate and make time an enemy of faith in the God of love, truth, and wisdom portrayed in His Word.

Life in a Lava Tube on Mars

Life in a Lava Tube
Lava River Cave, Arizona

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.

Wandering Stars in the Sky

"Wandering Stars" in the Sky

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:

  1. It must have enough mass for gravity to cause it to become spherical, unlike an asteroid.
  2. It must not have enough mass to cause thermonuclear fusion, which would make it a star.
  3. 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

Measuring the Distance to Stars

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.

Mass and Acceleration at Light Speed

Mass and Acceleration at Light Speed

Yesterday we looked at the two postulates of Einstein’s Theory of Special Relativity. We saw how our view of time is changed by taking the two postulates and applying them to motion at or near the speed of light. Now let’s look at mass and acceleration at light speed.

Looking at the top equation, which we presented yesterday, you can see that at the speed of light, the equation’s denominator becomes 1 – 1, which is zero. Time stops. If the velocity could somehow exceed the velocity of light, the denominator would be the square root of a negative number, which is not possible.

Another one of Einstein’s equations is a description of length in the direction of motion. The second equation shows that an object’s length in motion (L’) is equal to its length at rest (L) times the quantity square root of 1 minus the velocity (v) squared divided by the speed of light (c) squared. Thus the faster you move, the thinner you are in the direction of motion. An object one meter long at rest would be .765 meters at half the speed of light. At the speed of light, it would disappear, because it would have no length. There would be energy, but no physical length. What travels at the speed of light? The answer, of course, is light itself. Light is two-dimensional. It has no thickness in the direction in which it is moving, precisely what Einstein’s postulates predict.

Mass is another quantity that is affected by Einstein’s postulates. The equation for mass is similar to the equation for time. The mass in motion (m) equals the mass at rest (m’) divided by the square root of 1 minus the velocity squared divided by the speed of light squared. As an object moves faster, its mass increases, but it can never reach light speed. What, then, can we know about mass and acceleration at light speed?

One of the fundamental laws of physics is Newton’s Second Law. It says that when we apply force to a mass, the force (F) depends on the amount of the mass (M) and how much we want it to accelerate (A). The equation is F=MA. At the speed of light, the mass of an object would be infinite, and the force required to accelerate it to that speed would also be infinite. Because of the magnitude of the force, the mass would collapse into a black hole long before reaching light speed. So, it is not possible to achieve mass and acceleration at light speed.

Scientists have verified these formulas experimentally. When you accelerate a sub-atomic particle to a high velocity in a particle accelerator, its mass increases. So what created the mass in the first place? Infinite force – one of the properties of God. Proverbs 8:22-31 finds “Wisdom” is the tool God used for everything He created. Einstein has given us an excellent way to get a small understanding of the creation we live in and the wisdom and power of the God who created it.

Tools to Counteract Greenhouse Gases

Tools to Counteract Greenhouse Gases - Diatoms

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.

Why Do Birds Fly North in Spring?

Why Do Birds Fly North in Spring?

We all understand why birds of the Northern Hemisphere fly south in the fall. When the temperatures drop in Michigan, and the lakes are covered with ice, most birds have found a warmer place in the south. Michigan has many so-called “snowbirds” in the human population who leave us in November to go to Florida’s sunny shores. They come back in the spring to enjoy Michigan summers and because they have family here. The question is, why do birds fly north in spring? Couldn’t they save a lot of trouble by just staying in the south all year?

The answer to that question is food. The fact is that tropical areas simply don’t have enough insects to provide the protein that birds need to feed their chicks. When birds are in the south, they survive by eating berries, fruits, and nectar. None of those foods provide much protein. The time when birds return to the north coincides with the explosion of insects in the spring. They can enjoy less competition and longer days while dining on insects in the north.

The question remains as to how the birds know this? How do they know that they can benefit by traveling hundreds or thousands of miles in the spring? Why do the birds have the urge to fly north at the time that benefits them as well as the ecological systems they help to support? In other words, why do birds fly north in spring? The answer is that it’s built into their genes.

God’s view of Earth and the systems that make it work is far greater than ours. We are beginning to understand how many things, such as bird migration, must happen for the system of life to exist. It also speaks to us about how important it is that we take care of what God has given us.
