How The Sun Works

How The Sun WorksWe depend on the Sun every day to generate the energy that makes life on Earth possible, but have you considered how the Sun works?

The key to the Sun’s energy-supplying ability is a delicate balance between gravity and electromagnetism. Gravity curves space and pulls together all objects that have mass. The greater the mass, the greater the force of gravity. Right now gravity is pulling us toward the center of the Earth, but we are being held in place by the strength of the Earth’s crust and whatever floors or objects we have below us. The strength of the surfaces supporting us comes from electromagnetic forces between electrons and the protons in the nucleus of atoms. Those forces bond atoms of elements to each other forming compounds.

Since the Sun’s mass is more than a million times that of Earth, its gravity is more than a million times as great. The tremendous force in the core of the Sun overcomes the electromagnetic force and squeezes atoms of hydrogen tightly together igniting a thermonuclear reaction producing helium.

The creation of helium atoms releases high energy gamma-ray photons. If those gamma rays reached Earth, they would kill us. But the vast majority of them are transformed before they leave the surface of the Sun. On the way from the core to the surface they bounce off protons and electrons heating the hydrogen gas in the outer portion of the Sun. That heating increases the gas pressure enough to overcome the pull of gravity. Otherwise, the Sun would collapse on itself.

The bouncing of those gamma rays slows them so much that it takes hundreds of thousands of years for them to reach the Sun’s surface. If they could travel in a straight line, it would take only seconds, but they would emerge as deadly gamma rays that would reach the Earth in eight minutes, destroying all life. By the time those sterilizing gamma-ray photons reach the Sun’s surface, their energy has mainly been reduced to life-giving optical photons. There are still some dangerous rays that reach the Earth, but our atmosphere takes care of most of those.

That is a very simplified description of how the Sun works. Our Sun is a special star that provides the energy needed to sustain life on Earth without the high-energy rays that would destroy it. As you enjoy a beautiful sunset, you don’t have to know how the Sun works, but the Creator did. This finely-tuned system shows evidence of design by a Master Engineer, not a chance accident.

California Poppies Thrive

California Poppies ThriveThe past twelve months have been a time that most native Californians will never forget. After several years of drought, the entire state was affected by massive forest fires. When the fires were finally out, it seemed that everything would get back to normal, but then the rains started. Between the heavy snow and the unusually heavy rains, massive flooding became an issue. Without vegetation to stop the runoff, gloom and doom predictors were having a field day. The future looked bad, especially for southern California, but then came the California poppies.

I recently got a letter from a friend of mine who lives in southern California. The letter included pictures of what a few months ago was ugly, dark-colored, barren rock. The new images were ablaze with color. The California poppies withstood the fire because their seeds are not combustible and germinate faster in the conditions the fires produced. The seeds are also shaped in such a way that they don’t wash out even in heavy rain. With no competition, no predation to destroy the young plants, the poppies grew and bloomed like crazy.

Norma Privitt writing in the July/August/September 2019 issue of Power for Today described it this way:

“What a year this has been for California poppies! Abundant rain has unleashed God’s glorious array of orange flowers over all the barren hills. Even the limitations of TV do not restrict the obvious explosion of color. We traveled to view the poppies in previous years when their glory was only a smidgen of this year’s, but so many have made this year’s pilgrimage their cars line both sides of the roads, and finally, shuttle buses have had to be arranged. It almost seems symbolic that the plant that will anchor the soil and allow the land to begin to recover is a plant that blooms with brilliant orange drawing attention to God’s provision, even when human greed and abuse cause pain.”

Through California poppies, God has provided a way to bring beauty and hope even when things look dark and bleak.

Beautiful Tulips in History and Culture

Beautiful Tulips in History and CultureTheir vibrantly colored blossoms are symbolic of spring. Tulips are part of the lily family (Liliaceae) and exist in many different species. They flower in the spring and die back in summer when the life is stored in an underground bulb until the next spring. Beautiful tulips are an excellent example of the beauty designed into this planet.

Tulips are known for their bold colors and attractive shape. Most varieties are almost perfectly symmetrical. The blooms have three petals and three sepals, but the tulip appears to have six petals because the sepals are large and generally the same color as the petals. You can find tulips in almost any color from white to black, but the bright and sunny colors are the most popular.

Without a doubt, beautiful tulips have a rich and interesting history. They originally grew wild in temperate areas from southern Europe to central Asia. They were first cultivated in Asia around the tenth century. Diplomats who visited the Ottoman Empire in the sixteenth century brought them back to Europe where they became hugely popular.

The tulip obsession began with Flemish botanist Carolus Clusius in 1594. He was the first person to identify “broken tulips,” which is a virus infection that causes impressive streaks in the petals. He would go on to create many different color variations of the flower. His amazing tulips led to a period from 1634 to 1637 called “tulip mania” when enthusiasm for the flower created an economic frenzy. Tulips quickly became the most expensive flowers in the world. At the peak of tulip mania, some bulbs were selling for ten times more than the annual income of a skilled worker. People even used tulip bulbs as currency. Artists of the Dutch Golden Age, including Rembrandt, depicted tulips in their paintings.

Today, the tulip is the national flower of Turkey and Afghanistan, but the most prolific producer of tulips is the Netherlands. There are annual tulip festivals around the world including the Netherlands, England, Switzerland, Canada, and even Australia, where the spring bloom occurs in September and October. Several locations in the United States have tulip festivals, including Holland, Michigan, which is near where we live.

It’s interesting how tulips could have such an impact on economics, culture, and history. God gave us beautiful tulips, and human intelligence has modified them to develop a variety of colors and patterns. If human intelligence could do that, think how much more intelligence was required to create the living plant with the genetic code that made it all possible.

How Far Away Is the Sun?

How Far Away Is the Sun?Does it matter how far away the Sun is? Absolutely yes. The picture shows the order of the planets in our solar system, but not their distance from the Sun. So how far away is the Sun from Earth?

Any star that has planets orbiting it may potentially create a “habitable zone” where the light and heat are just right for the possibility of life to exist. Earth resides in the middle of the Sun’s habitable zone with Venus and Mars near the edge of the zone. Of course, there are many other factors required to support any kind of life, and it appears that Earth is the only planet in our solar system that has all of those factors. Earth has everything needed to support not just primitive life, but advanced life.

So what is the range of the habitable zone? That depends on the star. The size and brightness of the star are critical. Another essential factor is the type of radiation emitted by the star. Our Sun has the just-right radiation. Other stars may emit x-rays, gamma rays, or other deadly radiation in amounts that would destroy all life and prevent a habitable zone from existing.

Back in the eighteenth century, scientists determined the distance to the Sun by watching a transit of Venus across the Sun. Venus passes between the Earth and the Sun twice every hundred years or so. By measuring the time of the transit of Venus from two locations on Earth, scientists were able to use triangulation and simple math to calculate the distance to the Sun.

But the question was, how far away is the Sun? The Sun is about 93,000,000 miles (150,000,000 km) away from us. Since the speed of light is 186,000 miles (300,000 km) per second, it takes about eight and one-third minutes for the light from the Sun to reach the surface of the Earth. The energy the Sun delivers to our planet is just right to make life possible.

If someone asks you “how far away is the Sun,” you can say it is the “just right” distance. There are so many “just right” features of our planet that we can genuinely say we are in the “Goldilocks Zone.” Some think it was all just an accident, but we believe it was God’s plan and design.

Science and Technology vs. Greed and Stupidity

Science and Technology vs. Greed and StupidityIf you believe everything you read about science and technology in magazines and newspapers, you might want to question how much of it is factual. The way the media presents the stories, you might get the idea that science and technology are making such rapid advancements that in a few decades, we will solve all of the problems of humanity. There is no question that incredible advances have been made in medicine and agriculture. However, what many people don’t realize is that while some critical areas are advancing, others seem to be losing ground.

The Centers for Disease Control and Prevention tells us: “An American mom today is 50% more likely to die in childbirth than her own mother was.” The primary cause seems to be that health professionals have biases causing them to overlook symptoms. Food shortages are also creating an increase in disease and death due to malnutrition. The primary cause is that there has been a 20% drop in the abundance of food production in countries that depend on their domestic food supply. Humans have reduced the population of pollinators, including wild bees, endangering crop production. Over-fishing is beginning to threaten the primary source of protein for billions of people. The human destruction of mangrove forests and coastal coral reefs has placed 300 million people at increased risk of flooding.

God has given us not only the resources to feed every human on the planet today, but also the way to live with each other to allow the maximum potential for the food and medicine to reach the people who need it. The Genesis account tells us that God gave Adam everything he needed and that by the sweat of his brow, he would be able to eat. Humans have allowed power and control to rule what we do. We have made money and possessions the focus of our activity instead of focusing on God and serving others. In the process, food has become a weapon. Instead of “taking care of the garden, dressing and keeping it” (Genesis 2:15), we have exploited and abused the good things God gave us.

The world continues to reject the teachings of Jesus, replacing them with selfishness, greed, and a moral code that teaches “survival of the fittest.” The result is that we all reap the consequences of what we have sown. Bringing people to believe in God and Jesus Christ not only has meaning in terms of what lies beyond this life, but it also is at the root of the quality of life we and our descendants will have in the future. Science and technology can’t solve all of our problems as long as greed and stupidity get in the way.

Greenland Stromatolites and Faux Fossils

Greenland Stromatolites are Faux Fossils but this one is real.An old joke which showed up periodically during my college graduate work said, “Be sure your data conforms to your conclusions.” Because grants and scholarships depended on having success in your scientific research, it was tempting to cherry-pick data to support whatever you were claiming about your topic. That problem is still with us, and it has shown its head in reports of Greenland stromatolites.

Stromatolites are fossil deposits made by algae. (The picture shows a stromatolite fossil.) We see them not only in some shallow marine environments today, but we also find them in some of the oldest rocks on Earth. The Gunflint Chert along Lake Superior in Ontario contains some of the earliest stromatolites, but the rocks in Greenland are even older. Because many theories of the development of life on Earth depend upon finding marine life forms in Earth’s oldest rocks, there have been several premature news reports of Greenland stromatolites.

Abigail Allwood is recognized as an expert on stromatolites and has studied the oldest known stromatolites in Australia. She went to Greenland to examine the Greenland stromatolites. She concludes that they are not fossils, but only rocks that have experienced a great deal of tectonic activity. Ms. Allwood collected rocks just a few feet from the claimed stromatolites and found significant evidence of diastrophism, a type of plate tectonics which deforms Earth’s crust. She found no evidence of real fossils.

Naturally, the authors of the original paper on the Greenland stromatolites disagree with Allwood, but that is the way science works. Scientific testing answers the questions of authenticity and eventually reveals the truth. Unfortunately, false religious theories are frequently untestable and stay in existence for a very long time.

In science and faith, we should follow the evidence wherever it leads. It appears that in the case of the Greenland stromatolites, we have faux fossils and not the real thing.

Properties of Light

Properties of LightWhen you open your eyes in the morning, take a minute to thank God that you can see. We should reflect upon how good it is to have light instead of the darkness of night. The properties of light make it unique and special.

I am keenly aware of my gift of sight because of a long association with Glynn Langston, who is blind and manages our outreach to the visually impaired. In my lectures, I frequently refer to Edwin Abbott’s book Flatland to help people understand dimensions and how the spiritual is different from the physical. Glynn was born blind, so he is unable to visualize the concept of a sphere crossing a plane and leaving the outline of a circle. He has been kind about it, but my wife once said to me, “How do you expect a blind man to visualize anything!” Even those of us who can see have trouble understanding the properties of light beyond what meets the eye. Radio waves, gamma rays, X-rays, ultraviolet rays, and infra-red rays are all light!

The properties of light make it difficult to comprehend. The most general definition of light is that it is the energy released when a charge changes momentum. The bundle of energy released is called a photon, and the amount of change in momentum determines the energy of the released light. Even in the visible spectrum for humans, the different colors we see are determined by how much energy the light has. Violet has much more energy than red. Ultraviolet has more energy than violet. X-rays and gamma rays have even more energy, but they are still light. Infrared, and radio waves have lower energies than red. That is why infrared warms you and ultraviolet gives you a sunburn. It is also why radio waves can pass through the walls of your home without causing damage and gamma rays can also pass through things, but they will do significant damage.

In the creation process, there had to be special accommodations for the properties of light coming to Earth from the Sun and from outer space. The ozone layer had to be in place to absorb ultraviolet and avoid damage to life. The eyes of every living thing that uses some form of sight had to be designed to function in the part of the spectrum that fit its diet. Rattlesnakes, for example, have specialized sight organs to see in the infrared. Because they eat rodents whose bodies give off radiation in the infrared, a rattlesnake can see its prey on the darkest night. Nearly every insect sees some part of the spectrum other than the colors visible to humans. That is how a mosquito finds you and how insects navigate at night.

Not every star in the sky gives off the properties of light that are needed for life to exist. Some stars radiate in the X-ray part of the spectrum, and others radiate energies too low to be useful to life. Even our trees and shrubs require light in the green part of the visible spectrum to know when to shed their leaves in preparation for winter. In Job 38-41, God spoke to Job to show His wisdom and design and convince Job of his ignorance. Many of the designs God pointed to are connected to light. “Where is the way where light dwells, and where is the location of darkness?” (38:19) “By what process is light parted which scatters the east wind upon the earth?” (38:24) “How does the eagle seek the prey and see that which is afar off?” (39:29)

The Bible speaks of light that is not produced by the acceleration of an electric charge. The most important of these is described in Matthew 5:14-16: “You are the light of the world … let your light so shine before men that they may see your good works and glorify your Father which is in heaven.” Let those of us who are Christians not only be amazed by God’s design of the properties of light and the world in which we live, but let us also strive to be the light Jesus calls us to be.

What Happened to the Teays River?

What Happened to the Teays River?Yesterday, we talked about the Teays River and how, like other rivers, it brought water into dry areas. (To read yesterday’s post, click HERE.) The map above shows the approximate path of the river and its tributaries. But we didn’t tell you what happened to the Teays River.

As glaciers came southward across North America, they buried the river and its tributaries with massive amounts of sand and gravel. In the process, the river’s flooding and flowing impounded massive quantities of water. The Teays still exists today in water stored underground. I can drill a well 12 feet (3.7 m) in my back yard and hit potable water. The agricultural blessing of the Teays has made the Ohio River Valley fertile and has allowed cities to exist in areas that are not blessed with great surface water. What happened to the Teays River is still affecting our lives today.

In addition to the benefits we mentioned yesterday, the flooding of rivers also spreads diverse plants and the wildlife that feeds on them. The biggest watermelon I have ever eaten I found on an island on the White River near Spencer, Indiana. A friend of mine who enjoyed it with me recognized the species of melon, and we eventually found the patch that it came from some 75 miles upstream. In our trips through the Grand Canyon, we have frequently found plant life not native to Colorado thriving on sand bars in the canyon. When our river here in Michigan flooded in February of 2018, a layer of black soil was laid down in my yard and the woods on the edge of my property. Now there are dozens of plants growing in that soil which are not native to Michigan. Animal life of all kinds eat many of those plants.

Rivers are the cleaners of both the land and the water. One interesting part of living on a river is watching what floats by – a log, a tree, human junk, and all kinds of minerals. When the river dumps its load in a delta or an alluvial fan, the minerals become available for human use. In the Colorado Plateau, an ancient river carried and deposited logs containing uranium. The water moved those logs and impregnated them with uraninite, a mineral used to obtain precious uranium for nuclear materials. In my college studies in geology and mineralogy, we learned how to “read” a river and use that information to locate critical materials for technology.

It is essential that we take care of our rivers. We need to understand rivers and recognize God’s design in creating a planet molded and shaped by flowing water. What happened to the Teays River was caused by ancient glaciers that carved the land and created the Great Lakes. What happens to our rivers today depends on us and our stewardship of what God has given us.

From Genesis to Revelation, we see rivers as critical elements in the story of human existence now and in the future. The most important river of all is described in Revelation 22:1-2: “And He showed me a pure river of water of life, clear as crystal, proceeding out of the throne of God and of the Lamb. In the middle of the street of the City and on each side of the river was a Tree of Life bearing 12 crops of fruit and the leaves of the tree served as medicine for the healing of the nations. And there shall be no more curse: but God’s throne and the Lamb shall be in it.”

Rivers Are Essential

Rivers Are EssentialThose of us who live near rivers are both blessed and cursed. My house here in Michigan is located just 30 feet (9.1 m) from the St. Joseph River. In the almost 25 years that we have lived here, the river has flooded a dozen or so times. Twice we had water in our basement requiring a major effort to avoid damage to our library, our TV recording studio, and our packing room. Despite the challenge, rivers are essential to life.

A large percentage of all flooding results from human mismanagement. Black-topping many square miles of sand, gravel, and dirt has caused rapid water runoff where it previously soaked into the ground. Building homes and businesses on flood plains has contributed to the damage and in some cases loss of life. (Our house is not on a flood plain.)

On the other hand, there is beauty and peacefulness that being near a river provides. For many of us, that makes it worth the risk. Humans have used rivers extensively for thousands of years. Two-hundred years ago, rivers were the primary method of transporting goods and people. But there are some things that rivers do that are less obvious and which are an essential part of the design of the Earth.

Rivers above and below the ground carry water for us to use. They take water to places where it would otherwise not be available in significant volume for agriculture and animal life. Good examples of this are the Colorado River, the Rio Grande, the Nile, and the Euphrates. Rivers are essential for us to live on this planet, and flooding is a part of that.

One of the great rivers of the world was the Teays River. (Pronounced Taze) The Teays River got its name from the village of Teays, West Virginia. (Although the village of Teays did not exist at the time the river was there.) When it was at its greatest volume, The Teays River was a mile wide and flowed from what is now Blowing Rock, North Carolina, northward through Virginia, West Virginia, Ohio, Indiana, and Illinois where it joined the Mississippi River. At that time, the Mississippi was as much as 25 miles wide in places.

The Nile River in ancient Egypt flooded every year and laid down topsoil making Egypt the breadbasket of the ancient world. Remember where Jacob sent his sons to get food when there was famine? (See Genesis 41:56-42:5.) The Teays River was a typical river. It flooded from time to time laying down rich topsoil. The flooding of the Teays River deposited the black farmland of Illinois.

Rivers are essential to life, and that includes the Teays River. Did you say you never heard of the Teays River? What happened to it? More on that tomorrow.

Scientific Method Is a Friend of Faith

Scientific Method Is a Friend of FaithOur mission statement is: “Science and faith are friends and not enemies.” One of the challenges that we hear from atheists and skeptics is that statement is bogus because the scientific method can not be applied to it.

As a public school science teacher I always tried to make sure that students knew what scientific method is and could see how to apply it to the problems we face in the modern age. Sometimes that is incredibly difficult to do. Our textbooks usually gave six steps to use the scientific method:

1. Identify and define the problem.
2. Accumulate all possible data.
3. Formulate a tentative hypothesis that would solve the problem in step 1.
4. Conduct experiments to test the hypothesis – the more experiments, the better.
5. Interpret the results of the experiments without prejudice.
6. Repeat the steps until you find an acceptable solution.

In high school science classes, those six steps are usually easy to do, but sometimes later data alters what we thought was a solid fact proven by scientific method. Suppose we ask, “What causes gravity?” We could say “I think gravity is a property of mass.” All objects with mass have a gravitational attraction for all other d objects that have mass. Other people might say that it’s a property of electric charge, or maybe spin. You write down all the possibilities and conduct experiments to see which hypothesis can be experimentally verified.

To see if mass produces gravity, I fill two large bags with cement, and I hang them close to each other. If mass causes gravity, they should attract each other. That is an experiment I can do. I can also charge two balls electrically and see if they attract each other including the electric forces in the calculation. I can spin the two balls and see if they change their attraction for each other as they spin. The mass experiment works, and all the others don’t. I publicize my results and wait for additional experiments to support or deny what my experiments have shown.

The example I have just described is in most physics textbooks and has been done and repeated hundreds of times. But then a scientist did an experiment that didn’t support this conclusion. He found that when a beam of light passed by a huge object (the Sun), the light curved. This suggested that gravity was actually a product of space, not mass. The difference was that the size of the experiment produced different results when you used a star instead of a bag of cement.

As we have looked at the very large (quasars) and the very small (quarks), we have found that the scientific method is hard to do and sometimes impossible. String theory, brane theory, multiverse theory, and a variety of other proposals simply cannot be tested by an experiment. For the time being at least, we cannot test them by scientific method. They are not alternatives we can hold up as fact. They cannot even be considered as serious scientific explanations since they cannot be demonstrated or falsified by scientific method.

Trying to use the scientific method in areas like psychology, sociology, and matters of faith are also frequently difficult. What we generally do is to rely on statistics to evaluate a potential cure for a psychological difficulty. Does a treatment method work? Is a particular activity statistically helpful in relieving a mental or spiritual problem? As more and more data become available, we examine that data. We must reject some psychological theories (like Freud’s view of sex) and use the data to make a new proposal we can analyze.

Christ challenged his followers to examine the data. When the disciples of John came to Christ to ask if He was the promised Messiah, He responded: “Go and tell John what things you have seen and heard: how that the blind see, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised …” (Luke 7:22). Jesus didn’t ask the disciples to take His word for it. He asked them to look at the evidence. The evidence supports the claims of Christianity. If we honestly examine the evidence, our investigation will lead to a better understanding of how our faith works.

The scientific method is not an enemy of Christianity. The whole basis of our ministry is to ask people not to blindly accept what anyone says. The title of our ministry is “Does God Exist?” and that is the question at hand. We offer data for our readers to evaluate. The tentative hypothesis is that God does exist and that intelligence and design will be seen everywhere we look in the creation. As you continue to look at new data, we hope that you will find the solution for the struggles in life. The scientific method is a friend of faith.
