Star and Planet Formation

Yesterday, we discussed the new information about the construction and size of the cosmos we are learning from the James Webb Space Telescope. The Webb telescope shows us the size of God’s physical creation as NASA continues to pump out new discoveries and better understandings of star and planet formation. Search “James Webb Telescope” on your computer and see for yourself.

One of the better understandings from recent Webb telescope data is what it takes to make a planet like Earth. The conventional understanding of planet formation was that as stars formed, they threw off material that gravity pulled together, forming planets. The Webb telescope has the resolving power and the infrared light-gathering ability to observe planet formation in different stages.

The first step in planet formation is for the star to actively produce elements needed for terrestrial planet formation. Quiet stars do not make the necessary elements since heavier elements will move toward the star’s center, not outwards. The star must spin fast enough to throw out the required heavy materials. That means gaseous planets like Jupiter are much more common in the cosmos than terrestrial planets like Earth.

The heavier elements in a planet come from exploding stars. That means planets will be more likely in certain types of galaxies, and galaxies have an evolutionary history, changing with time. The Webb telescope actually observes the changes in galaxies and star and planet formation. The creation process is still active, and new planets are being formed as we watch.

In manufacturing, we know that a machine is designed to take raw materials and mold and shape them into the desired final product. Years ago, I worked for a man who designed and built such machines, and his wisdom and creativity were incredible to watch. This designer didn’t use a blueprint or follow a manual. He had the skill to comprehend what the final machine would look like and what it would do.

As we watch star and planet formation take place, we see the wisdom and creativity of God. The writer of Proverbs wrote, “O you simple ones, understand wisdom and you foolish ones, be of an understanding heart” (Proverbs 8:5). The Webb telescope allows us to see the wisdom of the Creator in ways we have never imagined.

What We Learn from the Webb Telescope

With all the distractions going on in the world, it is easy to miss perhaps the most remarkable engineering accomplishment of human history. A telescope launched on Christmas Day 2021 is now much further from Earth than the Moon is. The Webb Space Telescope consists of 18 hexagonal mirrors with a total area of 273 square feet (69.54 x 46.46 feet) and can see things in space that can’t be viewed from Earth’s surface. The cost to make the telescope and place it in space was 10 billion dollars, so is it worth the price? Yes, it is! What we learn from the Webb telescope tells us more about God.

More than 40 years ago, J.B. Phillips wrote a book titled Your God is Too Small. The first thing we learned from the Webb telescope is that the cosmos is much bigger than we can imagine. The telescope can see things that no optical device on Earth can. We live in a galaxy containing roughly 100 billion stars, and we know there are many other galaxies in space. Webb has shown us vast numbers of distant galaxies, and as we measure how far away they are, we see what the creation looked like billions of years ago.

Let me give you a simple explanation of what that means. If you travel to a place 100 miles away at 50 miles per hour, how long will it take to get there? The answer is two hours. When we measure how far away these galaxies are, we can tell when the light we see left them. Light travels at 186,000 miles per second. Doing the same calculation, we know the light reaching the Webb telescope left those galaxies some 13 billion years ago. We are looking backward in time to near the beginning of creation.

The latest pictures from Webb show that these old galaxies are flat like a sheet of paper. We learn from the Webb telescope that the creator was molding and shaping galaxies into a form that would allow planets and, ultimately, life to exist. As we understand the creation process, we see power beyond what we can imagine. Like all scientific discoveries, that raises many new and exciting questions for us to study and understand. It further tells us how unique Earth is and raises an old question the ancients asked about God, “What is man that you are mindful of him” (Psalms 8:4).

What Is Gravity and How Does it Work?

Many things in the creation do not lend themselves to conventional science. Gravity is an excellent example. What is gravity, and where did it come from? Issac Newton suggested that gravity was a property of mass because the more mass something has, the more it weighs. A physics equation describes gravity, saying that if you have two masses, there will be a force of attraction between them.

In a high school physics experiment, we hung two large bags of sand near each other. Gravity would pull them toward each other, and if you increased the amount of sand, it would draw them closer. Using a group of levers, the students could measure the force between the two bags. We can measure it, but what is gravity?

Instead of bags of sand, scientists measure the gravity force between the Earth, Moon, and Sun. What keeps Earth orbiting the Sun and the Moon orbiting the Earth? Isaac Newton proposed that the distance between objects affected the amount of gravitational force between them. An equation describing the attraction between masses 1 and 2 must include the masses, the distance between them, and a number known as the gravitational constant. The equation is F = G (M-1)(M-2)/X². G is the gravitational constant, and scientists have measured it to be 6.67 x 10^-11. If the value of the constant G differed from what it is, the Earth could not exist, and neither could we.

If you don’t follow all of that, don’t worry about it. The point is that gravity is a complex quantity that holds everything together. But that leaves questions unanswered. What is gravity? Is it a wave? How can it work over huge distances? How can mass cause gravity – or does it? Why is the gravity constant precisely what it is?

As science probes deeper into the nature of matter, time, space, and energy, it becomes increasingly evident that not everything physical has a physical cause. We cannot explain the creation of time, space, energy, or gravity by conventional science. As you read modern research reports, you see that our world was shaped from dimensions beyond the four we know about. The laws that govern our world and the dimensions we live in do not fully describe the nature of gravity, time, or even space.

Ancient biblical writers guided by the Spirit of God understood that a wise Creator designed our world. The writer of Proverbs 8 personifies wisdom, giving it a feminine nature. Wisdom says, “O you simple, understand wisdom and have an understanding heart. The Lord possessed me in the beginning of His way before His works of old. I was set up from eternity, from the beginning and before the earth ever was.”

Open-minded contemplation of the creation leads to the recognition that an infinite intelligence beyond that of any human brought the physical creation into existence. We learn from the Bible that God’s purpose was to allow the war between good and evil to end once and forever and that we play an essential role in that war.

Extinction of Plant and Animal Species

Near the end of 2023, the U.S. Fish and Wildlife Service removed 21 species from the Endangered Species Act because they have become extinct. What causes the extinction of plant and animal species?

Many factors lead to extinctions. Dr. Hugh Ross says the fossil record indicates that half of the mammal species that existed at the time of Adam and Eve are now extinct. Human activities that can endanger species include habitat destruction, introduction of invasive species, and introduction of diseases. Of course, animals can endanger people in various ways, including introducing diseases.

Humans have endangered plant species by introducing invasive plants. Plants used for decorative purposes can become invasive. Examples are English holly and the tree of heaven. Some plants that have become invasive were introduced to serve a purpose, such as controlling erosion. An example is the kudzu plant.

At other times, humans have caused extinction by killing large numbers of a species such as the passenger pigeon. Because of hunting and habitat destruction, the dodo bird became extinct within less than a century of its discovery. Humans caused the extinction of the great auk by foolish vandalism. Today, poachers are endangering the rhinoceros by killing them for no good reason. By contrast, human efforts rescued the California condor after it became extinct in the wild.

Woolly mammoths existed alongside early humans, and some scientists say they were essential for the survival of humans in some areas. People used them for food and their skins for protection from the elements. Their bones became tools, building materials, and even musical instruments. These large animals also kept plant vegetation under control while spreading their seeds. We can not always determine the cause of the extinction of plant and animal species, and that is the case with woolly mammoths.

The extinction of the dinosaurs occurred before humans were on the scene. That is good because humans and dinosaurs could not coexist on the land or at the same atmospheric oxygen level. God used them to prepare Earth for humans, and He orchestrated their extinction before He placed Adam and Eve in the garden.

As we look at the extinction of plant and animal species, we learn some essential facts. From the beginning, God had a plan for life as He prepared this planet for us to be here. He gave the first humans the responsibility to take care of the Earth, but we have not done a very good job. Finally, God is still giving us a chance to do better, and we have had some successes. Serving God involves serving others and caring for what God has given us for human flourishing. We can only do that when we submit to His plan for our lives.

Survival in the Cold by Design

As I sit in my warm office in Michigan today, I look out at snow and ice. My outdoor thermometer registers -8 degrees, and I wonder how the ducks on the river, the squirrels on the ground, and the birds in the air handle these frigid temperatures. I enjoy watching the birds on my bird feeders and the squirrels chasing each other in the oak trees, but I wonder how they survive. Then I apply my knowledge of physics, and I understand animal survival in the cold.

I always enjoyed teaching the heat and thermodynamics section of my high school physics class. One of my lines that always got a laugh was, “Why do we need to wear clothes to survive, outside of the obvious one.” The point is that our skin is not very good insulation against the cold. In winter, we pick clothes with air spaces within the fabric because air is a very poor conductor of heat, so it insulates us from the cold. We use coats stuffed with goosedown or some facsimile to be well protected from the cold. Goosedown also insulates sleeping bags and quilts.

Chickadees visit my bird feeders regularly. They usually are relatively sleek birds that fly smoothly and efficiently. As I look at my chickadees on this day of -8 degrees, they are almost round. Their feathers are fluffed up to trap air, so the birds are well insulated for survival in the cold. They don’t fly as smoothly as they do in summer. They crowd my feeders and would sit there without moving if they could.

Squirrels have a different problem. Their coats give them some protection, but getting food is an issue when heavy snow covers everything. They need to keep warm but avoid activities that would sap their reserve of nutrition. My gaze goes to the top of the oak trees, and I see a large round ball of leaves and twigs. Many years ago, to expand our church parking lot, we had to take down a tree with a large round ball of leaves and twigs near the top. As the tree came down, a squirrel ran out of the ball. I put my hand into the nest to see what was inside. Even though the air temperature was 20 degrees, it was very warm inside the ball of leaves and squirrel hair.

God has equipped His creatures for survival in the cold, and His design enables our Michigan winter to throb with animal activity. Trial and error explanations are weak because survival errors are lethal. We can see design in the natural world that speaks of God’s wisdom and planning. The evidence allows us to “know there is a God through the things He has made” (Romans 1:20). Watching animals thrive in very cold conditions is an excellent example of that evidence.

Aliens Visiting Planet Earth

The media has been full of claims that the government is hiding evidence from the general public about aliens visiting planet Earth. In this day of lying politicians and scams and fakes, it is essential to not buy into any claims too quickly.

The claims that were leaked out to the general public include the following:

1) A group of U.S. airmen found a downed alien spacecraft in Rendelsham Forest, England.

2) Sixty-two children in Zimbabwe witnessed a flying saucer near their playground.

3) A UFO knocked ICBMs offline in Montana.

(4) Various videos from the US Navy show aircraft maneuvering beyond what any earthly craft can do.

All of these and others are included in a film titled The UFO Movie They Don’t Want You to See, produced by Brian Dunning. (It is available for viewing on YouTube at the link below.) The reason we are interested in this film is that there have been those who claimed that aliens are responsible for the Bible, that Jesus Christ was an extra-terrestrial, and that the biblical narrative was given by aliens to guide gullible people into believing in God instead of knowing their true origin. This film exploring evidence about aliens visiting planet Earth has no religious interest and, in fact, is promoted by skeptic organizations.

It is important to understand that it is not our intent to say there is no life in outer space. With the massive number of galaxies, stars, and planets, other life forms may exist. God may have chosen other methods to conduct the war between good and evil. The problem is that the nearest star to our solar system is 4.3 light years away, and the closest galaxy to our Milky Way Galaxy is 750,000 light years away. Those distances are too great to allow any civilization to have an interest in us. Science fiction about aliens visiting planet Earth would have us believe that time and space can be controlled by aliens with intelligence far beyond our own. Some people choose to believe that even though it requires much more faith than to believe in Jesus Christ as the Son of God.

Bristol Bay and God’s Design

There are many fascinating facts about Alaska. One of them is how landlocked species of fish, animals, and plants receive the required nutrients. With the weather extremes, short growing season, and lack of soil, making the area biologically rich requires an extraordinary life form. Fishing lodges thrive throughout the Bristol Bay area because sport fishers consider it one of the most desirable places to catch wild salmon and trout. In addition to the sport fishing, native people and commercial fishing operations make a living in the Bristol Bay area. Both humans and wildlife in the area depend on one fish species, the red salmon, or as it is also known, the sockeye.

More than 60 million wild salmon pour into Bristol Bay every year, sustaining the wildlife and human economy. Sockeye eggs provide food for all five species of Pacific salmon, but they also allow the land-locked species Arctic char, Dolly Varden trout, and rainbow trout to exist. The fry, smolts, and adults support commercial and subsistence harvesting.

The total mass of sockeyes each year is in the millions of tons. After the sockeyes have spawned, they die, and their carcasses provide nutrients that allow plants to thrive in an area with very little soil. Without the sockeye, the entire Bristol Bay area would be a biological desert unable to support any fish or animals that eat fish.

Mining operations are trying hard to get permission to establish several kinds of mines in the Bristol Bay region. Undoubtedly, such operations would create roads capable of hauling metals, mining equipment, chemical leaching, and waste materials. Supplying food and managing waste from hundreds of miners and support personnel living in the Bristol Bay area for years at a time could destroy the fragile ecosystem, harming those who depend on it. The more scientists study the ecology of Alaska, the more they become aware of its fragility.

Bristol Bay speaks of our need to care for the creation that God has placed in our hands. It is hard to experience this area and believe its formation and natural balance happened because of blind, accidental chance. We must not allow it to become a showcase for selfish human greed and mismanagement.

Why Women Have to Experience Menopause

We get some interesting questions in this age of skepticism and rejection of God. One that came up recently is why women have to experience menopause. Like many questions raised by those who wish to deny God’s existence, this question is rooted in ignorance and a failure to think carefully.

Most members of the animal kingdom die when they can no longer reproduce. Mammals such as elephants and orangutans remain fertile throughout their lives. The number of animals that live beyond their reproductive years is very small. It has only been documented in a few species, including humans, orcas, and short-finned pilot whales.

There is no scientific explanation for the uniqueness of the human reproductive cycle. Dr. Shankar Singh of McMaster University in Canada maintains that this is because men favor younger mates, but this evolutionary explanation ignores the genetic implications that come with it. The more logical explanation of this fact is the different roles women have at various stages of life. In Titus 2:1-5, Paul talks about older women teaching younger women.

As we get older, our roles change. There is a reason for humans to live beyond the time when they can produce offspring. Teaching, leading, and serving can be more effective when done by older humans. That is not true of fish, birds, rodents, insects, or most mammals.

It is a good design that older women can no longer reproduce. My 70+-year-old wife says the thought of having a baby at her age is appalling. For orangutans and elephants, a female having offspring late in life helps maintain the species, and the whole group raises offspring, not just the mother.

Instead of asking why women have to experience menopause, we should note that God’s remarkable design of reproduction uniquely shows His handiwork.

God Gave Predators the Tools They Need

The balance we see in the natural world is strong evidence for design rather than chance. God gave predators the tools they need to control the population of animals that reproduce in large numbers. Owls are a great example of skillful predators. Rodents can cause significant harm to humans if their populations get out of control. However, in some cases, humans have interfered with the natural function of the predators of mice and rats, allowing the population of those rodents to grow to the point of threatening human populations.

In places where humans have not interfered with the natural balance, the design features of predators allow them to control rodent populations. Winter snow cover benefits rodents because they can move under snow. This security would let rodent numbers explode were it not for predators designed to catch them under the snow. One of those predators is owls.

An owl can capture a rodent under two feet of snow by detecting infrasonic low-frequency sounds. Dr. Cristopher Clark at the University of California, Riverside, has been studying how the design of owls allows them to have this skill. Using modern equipment, Dr. Clark has found that only low-frequency sounds can penetrate deep snow. The owl’s facial disk is especially sensitive to these low-frequency waves, and the infrasonic detectors are located right behind each eye. The owl will hover in midair over a spot where it senses prey. When the owl receives the low-frequency sounds, it plunges into the snow to grab the prey with its talons.

Between owls, foxes, and some subsurface animals, God gave predators the tools they need to control the rodent population, protecting humans. The predators’ special equipment is required to remove the rodents, and the design of that equipment indicates it was not a mere accident.

Loneliness Crisis Is Deadly

A recent USA Today article gathered data from the University of Michigan and Harvard University, showing that loneliness has increased dramatically in the United States. According to the article, 61% of adults ages 18 to 25 feel profound loneliness. Harvard professor Jeremy Nobel has established an initiative called “Project Unlonely” to address this loneliness crisis.

Professor Nobel classifies three types of loneliness:
(1) Psychological loneliness – not having anyone to trust or confide in
(2) Societal loneliness – feeling systemically excluded because of such things as gender, race, or disability
(3) Spiritual loneliness – feeling disconnected from oneself.

The U.S. Surgeon General’s advisory report says that loneliness increases the risk of premature death by 26%, equivalent to smoking 15 cigarettes a day. The American Heart Association says that feeling lonely increases a person’s risk of heart disease by 29% and stroke by 32%, indicating that the loneliness crisis is deadly.

The U.S. Surgeon General Dr. Vivek Murthy says that the solution to loneliness is to take 15 minutes a day to reach out to someone you care about or look for ways to serve others. He says that when we are with someone else, we must give them our full attention and put away our devices. He further states that schools, companies, and healthcare facilities must adopt strategies to reduce loneliness.

Nowhere in the USA Today article is the Church mentioned. The fact is that the teachings of Christ offer a real solution to loneliness. Read Acts 2:41-47, and you will see an excellent cure for loneliness. Read Matthew 25:31-40 and see what Jesus considers essential in how we live our lives. Christians can avoid the loneliness crisis by becoming active in building relationships and serving others.

Having a relationship with Christ gives us an understanding of our purpose for existing. Loneliness results from a world dominated by “survival of the fittest” and “looking after # 1.” The loneliness crisis in America has become an epidemic and is just part of the collateral damage that comes from rejecting God.
