The Mysterious Neutrino

A fascinating science story involves the mysterious neutrino. The famous Italian physicist Enrico Fermi gave it that name, which means “little neutral one.” When I was a graduate student at Indiana University, we were told that neutrinos are the binding energy holding neutrons together. A neutron consists of an electron and a proton held together, making a neutral particle. When a neutron decays, it releases an electron and a proton. Measuring the energy of these two particles leaves a tiny amount of energy unaccounted for. Neutrinos explain that missing energy.

Scientists later discovered that the mysterious neutrino is present anytime there is a change in a nucleus. Neutrinos are so tiny they can go through virtually anything, making them extremely difficult to detect or measure. Researchers obtained neutrino measurements by putting detectors made of glass spheres on the Mediterranean Sea floor and reported their findings in February of 2023. Now, we know that some neutrinos are 30 times more energetic than any previously known neutrinos. They are vastly more energetic than photons that make up visible light, X-rays, and ultraviolet rays.

The media has named the mysterious neutrinos “ghost particles” because of their properties. The truth is that neutrinos tell us that what holds matter together is not the physical material we can sense. Science does not fully understand matter and the particles of which it is made—electrons, protons, and neutrons. Those particles are made of energy in a form different from what we learned in chemistry class. What message about God can we see in the mysterious neutrinos?

The Bible tells us that God is not a man. Isaiah 55:8-9 finds God saying “…my thoughts are not your thoughts, neither are your ways my ways. As the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts.” In Acts 17:28, Paul described the nature of God by saying, “…in Him we live and move and have our being.” John 1:14 tells us that the God of Israel BECAME flesh and lived for a while among us.” In Exodus 33:18-23, Moses asks God to show himself, but God tells Moses no human can see Him and live (verse 20). These passages tell us that God is not a physical being, and what He does is not by the processes that humans can use.

The more we know about what holds matter together, the more we realize that God’s methods and design are not by physical processes we know, understand, or can duplicate. It reminds us of the words of David in Psalms 8:3-4: “When I consider your heavens, the work of your fingers, the moon and the stars which you have set in place, what is man that you are mindful of him, the son of man that you care for him. You made him a little lower than the heavenly beings and crowned him with glory and honor.”

Freshwater Mussels and Design

Humanity’s war with pollution has a surprising helper in freshwater mussels. They are susceptible to any change in the water in which they live. When anything disturbs the quality of the water, these mussels close their shells. In Poland, fifty water processing plants use these mussels to monitor any contamination of their drinking water. Technicians attach sensors to the mussel’s shells with hot glue. When four of the eight mussels close their shells, they trip a sensor alerting control computers to shut off the water supply. After three months, the mussels are removed from service and returned to the wild because they adapt to water quality and become less sensitive.

When Joe Kramarz sent this information, I thought it was a joke, but it’s true, as the National Institutes of Health reported. Our thanks to those who send us information we might miss. In this case, we find it interesting that mussels are designed to avoid pollution in their environment. Freshwater mussels are just one example of many animals that monitor their environment, including bats, whales, corals, moles, and even groundhogs. Some of these may not directly benefit humans, but they help us understand that God has designed animals for a complex and changing world.

When God challenges Job’s understanding in Job 38-41, He refers to many things in the creation that show wisdom and design. We are still learning about many of those examples, but all of them are beyond human capacity to duplicate.

Evidence Against Marijuana and Alcohol

One of the tragic aspects of marijuana use is that scientific evidence and demographic evidence of damage have not yet been assembled. The National Center for Drug Use Statistics reports that there is a high cardiovascular risk in marijuana use, and the more it is used, the greater the risk. There is also a higher risk of stroke. More than ever, we are seeing evidence against marijuana and alcohol.

On the social level, Elton John, Time magazine’s “Icon of the Year,” told the magazine, “Legalizing marijuana in America and Canada is one of the greatest mistakes of all time.” John says that marijuana is addictive and leads to other drugs. He speaks from experience with a past of marijuana use. John’s personal experiences with drugs are explored in a new Disney documentary, “Elton John: Never Too Late.”

Taking care of the body God has given you is essential. It affects not only you but also your descendants. It is too soon to tell if marijuana contributes to babies born with physical or mental problems, but those of us who lived through the days of LSD have seen huge suffering among children and grandchildren of LSD users.

Alcohol, which is the most destructive drug available today, has been responsible for more suffering than all the wars put together in terms of the number of people affected. Proverbs 31:4-6 tells us, “It is not for kings to drink wine; nor for princes strong drink: Lest they drink, and forget the law and pervert the judgment of any of the afflicted.”

Proverbs 20:1 says, “Wine is a mocker, strong drink is raging: and whosoever is deceived thereby is not wise.” That was written before distillation, and it is even more true today. The evidence against marijuana and alcohol is growing.

Animal Coprophagy – Recycling Poop

One aspect of design in the natural world is that virtually no food goes to waste. To that point, researchers have discovered many instances of animal coprophagy, poop eating. A study published in the journal Animal Behaviour documents 150 species of animals ranging from adult black bears to baby koalas recycling poop.

Many of the animals could not survive if they didn’t eat the feces of other animals. One example is pikas, small mountain-dwelling mammals on the Tibetan Plateau. They could not survive the harsh winters if they didn’t eat the droppings of Yaks. Blind cave fish can’t leave the cave to forage for food, so they survive by eating the guano of bats that inhabit the caves. Cows have multiple compartments for processing food, but rabbits do not. Rabbits and other small animals survive by eating the droppings of larger animals that have eaten harsh foods, breaking them down to a form the rabbit’s gut can easily absorb.

You might think that animal coprophagy would lead to diseases and parasites, but the nutrition gained vastly exceeds the possible infection for many animals. Capybaras eat their own feces, so you can’t call it waste. An interesting fact is that lab rats eat up to 40% of the poop from other rats and even themselves. If lab workers prevent them from doing that, they become sick from vitamin B12 deficiencies. Insects such as dung beetles survive on animal dung.

Recycling poop gives evidence that God designed the animal world so food is not wasted. Meanwhile, humans are guilty of wasting food, leaving many people to starve. That is why Jesus Christ, in Matthew 25:35-46, told His disciples to give food and drink to those who are hungry and thirsty.

Symbiotic Relationships Show Design

A stable ecosystem needs all forms of life to benefit other life forms. When two living things mutually benefit each other, we call it symbiosis. A simple example I see from my window is squirrels gathering acorns that make up a large percentage of their diet. The squirrels bury acorns in various places around the neighborhood and either forget where they buried them or don’t need all the acorns they buried. The result is that oak trees are planted all over the neighborhood. If there were no acorns, the squirrels would starve. If squirrels didn’t plant the acorns over a wide area, the oak trees would be crowded and unable to grow successfully. Squirrels and oak trees are one example of symbiotic relationships.

In the insect world, there are many symbiotic relationships, and some insects have multiple such relationships. The red wood ant is an example. The ants have a symbiotic relationship with aphids, which excrete energy-rich honeydew, which supplies food for the ants. In return, the ants protect the aphids from their enemies.

Another symbiotic relationship is with Eurasian jays. The birds land on an ant mound and allow the ants to crawl on them, spraying their feathers with formic acid. The acid is low enough concentration that it doesn’t harm the birds but is strong enough to kill parasites, including mites, that hide in their feathers. In this way, the jays find protection from mites.

A third symbiotic relationship of red wood ants protects spruce forests by controlling the wood-boring beetles that destroy them. The ants bite the beetles and spray formic acid into their wounds. Killing the beetles protects the spruce trees and provides a home for the aphids that live in them. That takes us back to the ant-aphid symbiosis.

The multiple symbiotic relationships of red wood ants remind us that removing one species may affect many symbiotic relationships. Symbiotic relationships show design. Proverbs 6:6-8 tells us, “Go to the ant, you slacker! Observe its ways and become wise. Without leader, administrator, or ruler, it prepares its provisions in summer; it gathers its food during harvest.”

The Design of Mountain Goats

Every niche in the natural world has a designed relationship with plants and animals that live there. Goats thrive in a variety of environments that are unsuitable for other animals. The design of mountain goats allows them to run up vertical mountain slopes and even climb trees in areas where no ground forage is available. Their ability to run vertically up steep slopes protects them from predators like bears or mountain lions. The only predator goats have to worry about are those that can fly. However, eagles and hawks can carry away small young goats.

The secret that allows mountain goats to do these seemingly impossible things is their hoof design. The outer edge of a goat’s hoof consists of very hard material. The hoof has adjustable toes that can compress to a sharp point for digging or to gain traction on a narrow ridge. Mountain goats can also expand their toes for a wider surface. The hoof edges have pointed toenails to catch on small crevices in rocks. The center of the hoof has a soft, rubbery material that gives traction for walking.

People who raise goats have found them difficult to hold in a pen. They can scale any material the walls of an enclosure might be made of and even move about on a steel roof with ease. No other animal has all of the features that allow goats to thrive in places where other animals can’t survive.

The design of mountain goats is challenging to explain based on chance. They are uniquely designed to be the leading players in the ecology of mountainous areas. Their design speaks loudly of the statement of Romans 1:20 that we can know there is a God through the things He has made.

Size Extremes of Animals

We must be amazed when considering the size of dinosaurs and the number and function of insects. There have been very large or very small life forms throughout the history of planet Earth. The key to the size extremes of animals depends on ecological needs.

Fossils show enormous dinosaurs as large as a house and as tall as 50 feet. At the time of the dinosaurs, these animals could eat massive amounts of vegetation to provide the fossil fuels that humans would eventually need. They were larger than any land animal living today for good reason. Humans would be unable to share land areas with animals of that size, and predation would be an issue with carnivores the size of T. rex.

In today’s world, giant animals live in the ocean. The blue whale is the largest animal to ever live on this planet. An elephant weighs less than the tongue of a blue whale, and a blue whale’s heart is roughly the size of a car. They are not dangerous carnivores but eat massive amounts of small ocean creatures like krill. Without such a large consumer, the krill would overpopulate the world’s oceans and throw the ocean’s entire food chain out of balance.

Ants are closer to the small end of the size spectrum. For every human on this planet, there are roughly one million ants. Ants exist in many species, and each has particular functions. Some control the number of other insects, while others clean up human waste. Still others are integral to the plant kingdom as pollinators or as food for the plant.

Of course, there are microscopic life forms that make ants look huge by comparison. These size extremes of animals are not an accident, and they serve to sustain life today as they have in the past. Humans have the responsibility to protect the creatures God has created. Otherwise, Earth will become a lifeless ball of rock traveling through space.

Bat Migrations and Design

The disappearance of bats from various areas of the world when winter approaches has puzzled scientists for years. Dr. Edward Hume of the Max Planck Institute for Animal Behavior led a study of bat migrations to determine where the bats go and how they get there. Monitoring bat migration is difficult because bats are fast and travel at night. They have a very low mass, roughly an ounce, so tags used for birds are too heavy for bats.

New tags developed by Hume and his associates weigh roughly a gram (1/454th of a pound), so they can follow bat migrations. Research has shown that bats use the warm fronts that precede storms to ride the winds to travel as much as 1000 miles. There are many variables in this system, meaning that the timing and direction of the winds must be very precise to carry the bats where they need to go.

There is a very practical reason for understanding bat migrations. Wind turbines can kill large numbers of bats, so knowing the timing of the migrations can reduce this problem by shutting down the wind turbines. Bats are essential to control insect populations and produce guano used in fertilizers.

Romans 1:20 says we can know there is a God through the things He has made. Every creature science has studied shows unique characteristics. The “Does God Exist?” program has five volumes of books titled “Dandy Designs,” showing many of these, and more volumes will soon be available. The evidence for God’s wisdom and design increases with every discovery science makes.

Who Is to Blame for Cancer?

Whom do you blame when you learn you have cancer? Many people blame God, but human actions often cause cancer. It is well-known that alcohol causes 13,500 deaths from drunk driving every year in the United States. It is not well-known that alcohol causes 20,000 cancer deaths in the U.S. every year. Who is to blame for cancer?

Dr. Timothy Rebbeck, a professor of cancer prevention at the Dana-Farber Cancer Institute in Boston, says that alcohol has long been known as leading to cancers of the mouth, esophagus, breast, liver, and colon. However, he says that recent studies have shown “even occasional alcohol consumption” is associated with other kinds of cancer risks.

The human body breaks down alcohol into chemicals that damage DNA, causing cells to grow out of control and become cancerous. Alcohol can also block the body from breaking down nutrients, leading to increased cancer risks. It can increase the blood levels of estrogen, leading to a higher risk of breast cancer. When combined with smoking, the National Cancer Institute says the risk is “multiplicative.”

Alcoholic drink companies have suggested that drinking moderate amounts of alcohol is good for one’s health, but research shows that even one drink per day increases cancer risk. Who is to blame for cancer? Between alcohol, nicotine, pollution, and recreational drugs, a massive percentage of cancer deaths are caused by humans. Even second-hand smoke is a cause of cancer.

In 1 Corinthians 3:16-17, we read, “Do you not know that you are God’s sanctuary and that God’s Spirit has his home in you? If anybody desecrates the temple of God, God will bring him to ruin, for the temple of God is sacred, and so you are.” God does not cause cancer, but He does not prevent the consequences of taking dangerous substances into our bodies.

Possible Astronomical Catastrophes

The media often fills a void in natural disasters on Earth by headlining possible astronomical catastrophes. A recent example was a headline in USA Today stating that a “Rare but extreme solar event could disrupt life on earth.”

The article tells us that a solar superflare would fry communications satellites and produce electric currents strong enough to paralyze the power grid. The article tells us that in 1859, a violent solar storm knocked out the telegraph network in large parts of northern Europe and North America. It said if a solar superflare happened today, it would knock out phone services, GPS, credit card authorization, and weather and climate monitoring. The USA Today report is taken from the peer-reviewed journal Science, a publication of the American Association for the Advancement of Science.

So, what is the danger of a solar superflare to you and me? The answer to that question is “virtually none.” The point is that solar superflares occur in stars like our Sun roughly once every 10,000 years. The flare in 1859 was not a solar superflare but merely a flare for which the nascent electric industry was unprepared. Today, such a flare would not significantly affect today’s telegraph or phone service.

The lack of possible astronomical catastrophes shows the intelligence and design built into our planet and solar system. A G-2-type star, like our Sun, has infrequent occurrences of solar superflare. Other spectral classes of stars can have solar superflares every 1000 years. That means the occurrence of life on a planet around another star is highly unlikely, if not impossible.

In his 1956 CBS television program “Our Mister Sun,” the late Dr. Frank Baxter said, “The more we know of the creation, the closer we get to the Creator.” The lack of solar superflares is another example of the truth of his statement.
