Planet Parade Syzygy

Just before sunrise Monday morning, June 3, 2024, six planets and an asteroid will form a “planet parade.” That means they will appear in a straight line as viewed from Earth. The planets involved are Mercury, Jupiter, Uranus, an asteroid, Mars, Neptune, and Saturn, going from the horizon up. Understand that is how we see them from Earth because Mercury and Jupiter are nowhere near each other.

With the naked eye, you should be able to see Mars, Saturn, and Jupiter, with Jupiter being the brightest. With binoculars, you might be able to see Uranus. With a telescope and knowing where to look, you will see all seven; if the sky is clear, you are away from light pollution and have a clear view of the eastern horizon. However, a crescent moon will make viewing a little more difficult. By Thursday, the Moon will be out of the way to better view the planets, but Mercury and Jupiter will have switched places. The change of position will be caused by the outer planets (Jupiter) appearing to move more slowly than the inner planets (Mercury).

The planets’ ability to appear close together in the sky shows how flat our solar system is. In other words, the planets orbit the Sun in nearly the same plane rather than in random directions. That fact allows the outer planets, especially Jupiter, to serve as comet sweepers, protecting Earth from dangerous objects coming in from beyond the solar system.

A syzygy is a true alignment of planets, which happens very rarely. This planet parade is an interesting apparent alignment, and “syzygy” is a good word to remember the next time you play Scrabble. This beautiful view of our solar system reminds us of God’s wise artistic and engineering design.

What Created the Universe from Nothing?

At the beginning of the 20th century, many scientists, including astronomers and physicists, believed that the universe was eternal. Since it had no beginning, there was no need to explain what created the universe. In other words, there was no need for God.

That began to change in 1905 with Albert Einstein’s theory of Special Relativity. His calculations indicated that the universe was either expanding or contracting, but he could not accept that. He invented a “cosmological constant” to balance the effect of gravity. Other scientists recognized his error, which he later admitted was the greatest blunder of his life. Then Georges Lemaître theorized, and Edwin Hubble confirmed that the universe was expanding. Since it is expanding, going back in time to the distant past, the universe would become progressively smaller until it began as an infinitely small and dense “singularity.” That was the beginning of time, space, matter, and energy.

The concept of a beginning posed a significant challenge for many scientists due to its religious implications. Throughout the 20th century and into the 21st century, science continued to confirm that the universe had a beginning. Robert Jastrow, a prominent American physicist and director of NASA’s Goddard Institute for Space Studies, was one such scientist. Despite describing himself as an “agnostic, and not a believer,” He found the idea of a beginning unsettling as it implied a Creator. In his 1978 book God and the Astronomers, he expressed his discomfort in these words:

“This is an exceedingly strange development, unexpected by all but the theologians. They have always accepted the word of the Bible: In the beginning God created heaven and earth… The development is unexpected because science has had such extraordinary success in tracing the chain of cause and effect backward in time. For the scientist who has lived by his faith in the power of reason, the story ends like a bad dream. He has scaled the mountains of ignorance; is about to conquer the highest peak; as he pulls himself over the final rock, he is greeted by a band of theologians who have been sitting there for centuries.”

Even though scientists have scaled that mountain and made great progress in determining when the universe was created, they still cannot explain what created it from nothing. If there was nothing, how can there be a “what” to do the creating? Many scientists are believers in God, but others need to turn to the Bible to find the eternal Creator, the uncaused cause, the One Who created the universe and us for a purpose.

Animals Do Not Possess Human Values or Empathy

One result of evolutionary thinking is believing that humans are not unique but just animals at the top of the evolutionary ladder. As a result of that message, many people treat animals as if they are humans, at times even raising wild animals in their homes. The problem is that animals do not possess human values or empathy, and their instinctive behavior may cause unexpected problems.

In some cases, animals have reverted to instinctive drives, causing them to attack their owners. A man named Austin Riley in Boerne, Texas, found a newborn warthog whose mother had died. Riley took the tiny warthog, nursed it, and raised it for five years. He named the pet warthog Waylon after Waylon Jennings, a country singer known for his outlaw behavior. When Riley would lie down and listen to sports radio, Waylon would lie down beside him. Riley would take Waylon to Whataburger to get something to eat, and Waylon would sit in the front seat “happy as can be.” Waylon grew to weigh 250 pounds and was identified with Pumbaa in the popular Lion King movie, with the Swahili expression “hakuna matata,” meaning “no worries.” However, there was something to worry about in this case because animals do not possess human values or empathy.

Warthogs have lower tusks protruding from muscular jaws like blades. The tusks are curved, so the warthog can do incredible damage to any animal or person by twisting its head. Warthogs are designed to protect themselves from lions, their main enemies in their native Africa. On an October evening in 2022, Austin came to Waylon’s pen, and the warthog greeted him happily as he went to the feeding trough. Twenty minutes after feeding Waylon, Austin fed Daisy a potbellied pig he raised from a piglet and then walked to his ATV. Suddenly, Waylon attacked Austin, ripping his legs, wrist, abdomen, and neck. Doctors say that Austin lost half of his blood, and his treatment required ten surgeries. Medical studies of Waylon showed he did not have rabies.

The bottom line is that wild animals are not good pets. Animals do not possess human values or empathy. I have known friends who had snakes, alligators, turtles, deer, eagles, crows, chimps, goldfish, and even sharks for pets. In many cases, a time came when the animals acted aggressively toward their keepers. The point is that humans can behave like animals, but animals cannot behave like humans. Humans are created in God’s image, which is expressed in how we live and care for one another at all stages of life. The world would be a much better place if everyone followed the teachings of Jesus Christ in Matthew chapters 5 to 7.

Free Radicals are Chemically Reactive

One of the least understood design features of living things is the role of free radicals. The design of atoms and molecules calls for electrons to be paired for stability, but a free radical has unpaired electrons. With their unpaired valence electrons, free radicals are chemically reactive. Although some free radicals are essential to life, the accumulation of free radicals can cause cell damage.

Stress conditions such as radiation can cause harmful free radicals. Researchers have found that tiny animals called tardigrades (or water bears) exposed to stressful conditions curl up into a state of dormancy called a tun. That can explain their ability to survive in the vacuum of space, frigid temperatures, or radiation bombardment. The metabolism of the tardigrades shuts down in the tun state, but why is unclear. This intriguing discovery could potentially lead to practical applications such as medical treatments that slow the aging process, offering a glimmer of hope in the face of free radical damage.

Evolution cannot explain why free radicals are not chemically reactive. Scientists are studying the design of atoms and molecules with magnetic properties related to electron spin. This phenomenon goes back to creation itself. When God produced matter/energy in the beginning, electron spin, magnetic pairing, and free radical production were built into the very design of atoms and molecules. This design structure allows life to exist.

The future is bright as scientists learn more about the effect of free radicals on human health. Learning about the complexity of matter and life reminds us of “Wisdom’s” comment in Proverbs 8:22-23: “The Lord possessed me at the beginning of His work, before His deeds of old. I was appointed from eternity, from the beginning before the world began.”

Learn from the Woodpecker Design

Woodpeckers can hammer 25 strokes while their heads travel more than 20 feet per second. If you banged your head into a tree for a few seconds, the results would be headaches, detached retinas, concussions, eye damage from flying wood chips, and massive skin damage. With all the talk about brain damage from football collisions, perhaps we can learn from the woodpecker design.

Many design features protect woodpecker brains. Their skulls are thick and heavily ossified to prevent shattering. Shock-absorbing tissue between the eyes and around the skull acts as a crash helmet. Spongy material separates the skull and bill. A sac of fluid surrounds human brains, but a tough membrane surrounds a woodpecker’s brain to prevent it from bouncing around. The woodpecker brain is tiny, weighing a fraction of an ounce, so it has much less inertia.

Woodpecker eyes are held tightly in place by bone and surrounding tissue to prevent damage. A membrane blinks over the eye to keep out wood chips. The nostrils are covered with fine bristly feathers or are narrow slits to protect the bird’s air chambers. Woodpeckers have long tongues that reach deep inside tree openings to capture insects. The tongue wraps around inside the skull, further protecting the brain when the bird is hammering on the tree. The woodpecker’s bill is solid and shaped like a chisel. Thick and strong neck muscles absorb the kinetic energy.

Woodpeckers are essential to forest ecosystems. They control worms and insects that can infect trees, avoiding blight and infections. Medical personnel dealing with head trauma have much to learn from the woodpecker design. Design features requiring so many specialized features are difficult to explain by chance. A step-by-step evolutionary process can’t explain the production of the many unique features. God’s creatures are designed to do specific jobs, and “We can know there is a God through the things He has made” (Romans 1:20).

An Animal Using Photosynthesis

Animals use an enormous number of methods to get nourishment. Harsh environments often require unusual methods, and many times, the animal at the bottom of the food chain is unusual. An excellent example is the leaf slug or leaf sheep (Costasiella kuroshimae). This sea slug is an animal using photosynthesis to secure its nourishment by a method known as kleptoplasty.

Plants serve as the foundation of the food chain, harnessing sunlight through photosynthesis to produce energy. Many animals, such as herbivores, rely on plants to meet their energy needs. Even carnivores indirectly depend on plants, as they consume the herbivores. However, the leaf sheep, through a process called kleptoplasty, bypasses this reliance on plants and directly uses photosynthesis for its energy needs.

The leaf sheep, a sea slug measuring only five to ten millimeters long, was first discovered off the coast of Japan in 1993 and later found in the Philippines and Indonesia. Its common name derives from the two dark eyes and two rhinophores on the top of its head, making it resemble a tiny sheep. They feed on algae, which are plants that contain chloroplasts that enable photosynthesis. The leaf sheep retains the chloroplast cells within its body, enabling it to become an animal using photosynthesis. In this way, it bypasses the need to eat more algae for over two months. In the food chain, the leaf sheep become food for a variety of fish and other forms of sea life.

The more we learn about the natural world, the more we see unique systems that allow life to exist in symbiotic relationships that give evidence of design. Mindless chance does not provide the best explanation for examples such as leaf sheep. If there were just one such case, you might think it might be blind chance, but this is just one of a vast number of cases where a very specialized design allows life to exist. Everywhere we look, a “wonder-working hand” has gone before, and we would suggest that it’s the “hand” of God.

Green Sea Turtles and Migration

They are sea turtles with a carapace that is olive to black. So, why are they called green sea turtles (Chelonia mydas)? These sea creatures live in tropical and subtropical areas of the Atlantic and Pacific. They eat seagrasses along the shore by biting off the tips rather than pulling them up by the roots. By doing that, they keep the seagrasses healthy, and the green vegetation makes their body fat turn green, which is where they got their name.

Green sea turtles migrate far from their feeding grounds to various remote islands where they lay their eggs. Many of them live along the coast of Brazil, and a large percentage of those lay their eggs on Ascension Island. Ascension is a small volcanic island 1400 miles (2250 kilometers) out in the Atlantic Ocean. Because the prevailing equatorial current runs from Ascension to Brazil’s coast, it takes the adult turtles 50 days to swim from Brazil to Ascension Island. They make the return trip in less than 30 days, swimming with the current.

We could ask, “What advantage does this migration have?” The answer is easy. Ascension Island has sandy beaches where the turtles can lay their eggs. There are few predators on the island, so the percentage of the eggs that hatch and survive is high. When the hatchlings are ready, they paddle out into the equatorial current and float back to Brazil.

There are more challenging questions we might ask. How do these turtles locate Ascension Island? What caused them to go there in the first place? Can we explain this migration by chance? Researchers have made suggestions, but the answers remain unclear. Maybe the best answer is that God has provided a way for these slow and harmless creatures to survive. They keep the seagrasses healthy in their home areas while serving a role in the fauna of the isolated volcanic desert island called Ascension. Green sea turtles are part of God’s amazing web of living things.

We Look Up and See a Blue Sky

Most of us underestimate the design of planet Earth. We look up and see a blue sky and take it for granted, but having a blue sky is unique to our planet and tells us much about its design.

We must first understand that a change in electric charge produces light. The amount varies depending on the amount of change. Small changes produce light that is low in energy and may not be visible to human eyes. Radio waves are light we cannot see. Infrared waves are light humans can’t see, but numerous animals can. For example, a rattlesnake can see infrared light coming from a mouse even though human eyes would say there is no light. The mouse gives off infrared due to its biological processes, and the snake can see it in the dark. We call infrared light radiant heat.

A large change in an electric charge produces light that is too energetic for our eyes to see. Xrays, ultraviolet, and gamma rays are the words we use to describe these high-energy forms of light. They can expose a photographic plate and penetrate most organic tissue, possibly causing damage. The light our eyes are designed to see has lower energy than Xrays and higher than radio waves. This beautiful design of our eyes means we cannot see through most solid materials like wood, metal, or human flesh.

Light from the Sun arrives on Earth with all of these energies present. The Earth’s atmosphere is dense enough to prevent the high-energy forms of light from reaching the surface. That means we are not fried by the X-rays, gamma rays, or even excessive ultraviolet light coming from the Sun. The highest visible light that our eyes can see is blue. As blue light enters our atmosphere, it is scattered and refracted away by atmospheric materials. We look up and see a blue sky.

Green is the next highest energy reaching the surface. Plants are protected from damage because their chlorophyll reflects green light. When tree leaves lose their chlorophyll in autumn, the green disappears, replaced by other colors hidden within the leaf structure. Then, the leaves fall off to prepare the tree for winter. Annual plants shrivel and die while perennials retain their root structures to bring color back in the spring.

So we look up and see a blue sky. On the Moon, we would see a black sky. On Jupiter, it would be red. The atmosphere on all the other planets gives a color other than blue. Astronauts face huge dangers when leaving Earth’s atmosphere with its well-engineered light-handling design. To live on the Moon or Mars, human engineers must build elaborate designs to imitate what God created to allow us to live on Earth. That is the greatest challenge to space travel and a great demonstration of God’s wisdom.

Medicalized Child Abuse?

One of the most inflammatory issues of our day is the question of children who decide they want to change their gender. A team led by Dr. Hilary Cass, a renowned British pediatrician, recently produced a 388-page report based on four years of research into trans care in Britain. The UK’s Sunday Times reported that “Trans activists have bullied politicians and doctors into embracing ‘medicalized child abuse’ and cowed dissenters into silence.” That is a challenge to the same groups in America, but some public school counselors should be added to the group of abusers.

The number of British children referred for transgender drug and surgery treatments rose from 250, mostly boys, in 2012 to 5,000, mostly girls, in 2022. The concerns of medical experts like Dr. Cass are not because they are transphobic but because they are starting to see the consequences of medical sex-change procedures. The treatments for “gender dysphoria” have lifetime effects, including a loss of bone health and fertility, making the subjects lifelong patients for medical treatment.

The Times newspaper points out that the problem is likely more serious than anyone realizes because 6 out of 7 gender treatment centers refused to give data to researchers. Although this report is from Britain, we suspect the situation is worse in the United States. We have been personally involved in a case where a school counselor led a 14-year-old child to have puberty blockers and surgery. The cases we have had contact with involve children who needed psychological help in dealing with relationships.

Attempting to change God’s creation and design of the human reproductive system will cause children a great deal of pain and uncertainty. We suggest that medicalized child abuse is not the way to help disturbed children find their identity and live meaningful lives. We will see an increase in evidence for the destructive nature of medical gender-changing treatments for young people. God’s design works, but in today’s world, many reject God’s plan.

A Balanced System of Ocean Life

Kelp safeguards the ocean’s ecology by providing a home for many sea creatures, preventing coastal erosion, and sequestering vast amounts of carbon dioxide. The last century has seen a massive decrease in kelp growing along the California coast because of an increase in sea urchins that eat kelp. Sea otters feed on sea urchins, and as people killed sea otters for their fur, the urchin population increased, reducing the underwater kelp forests. It is easy to see that God has given us a balanced system of ocean life, but humans sometimes upset the balance.

Sea otters have a fast metabolism, requiring them to eat a fourth of their body weight daily, and sea urchins are their favorite food. Because of the fur trade, sea otters disappeared from Northern and Southern California, with a small population remaining in the central part of the state. In 1913, California made sea otters protected mammals, but 1977’s Endangered Species Act gave them more protection. Since then, central California has seen a 58% increase in kelp while kelp in the northern and southern coasts has declined. Research has shown that sea otters are the reason for the ecological improvement in Central California.

Any time humans disturb the balanced system of ocean life or any ecosystem, negative consequences result. The biological design of our planet does not just consist of separate independent organisms, but all of life on Earth is interconnected. An analogy might be the workings of an airplane. Multiple systems operate within an aircraft, including the landing gear, engines, electrical system, hydraulics, wings, rudder, etc. For it to fly, all of those systems must work together. Engineers must design a plan that integrates those systems. The aircraft doesn’t happen by accident but by the design of intelligent engineers.

All of life on Earth is interrelated and not a product of chance. There is design in all of life and in the planet itself that allows us to exist. In Proverbs 8, “Wisdom” encourages us to see God’s wise design on this planet. In verses 22-31, we see specific wisdom shown in various applications involved in preparing planet Earth for life. Verses 35-36, we see the alternative to understanding God’s use of wisdom in creating the world in which we live. Verse 35 tells us that those who find wisdom find life, and those who do not find wisdom harm themselves and prefer death. We all see all around us the interaction of living things and what happens when humans destroy one of them.

Let us learn from the balanced system of ocean life that includes kelp, sea otters, and urchins. Caring for all life is a challenge God has given us in Genesis 2:15. The need to do this is more clear today than ever before.
