Stronger than Gravity

Stronger than Gravity
Gravity controls the universe — at least on a large scale. Obviously, gravity keeps you and your possessions from floating away into space. Gravity also holds planets and stars together. It holds the Moon in orbit around the Earth and all of the planets in orbit around the Sun. Gravity holds the galaxies together. But other forces are stronger than gravity.

Four interactions make the universe work: the weak and strong nuclear forces, electromagnetism, and gravity. Gravity is by far the weakest of those forces. The weak and strong nuclear forces are limited to a very short range within the atom. Only the electromagnetic force and gravity reach out to the vast universe. Since the electromagnetic force is so much stronger than gravity, why does gravity control the universe?

Everything is made of atoms and atoms contain electrons and protons. Electrons have a negative charge, and protons have an equal and opposite positive charge. Electromagnetism causes opposite charges to attract and like charges to repel each other. Gravity, of course, pulls anything with mass together.

The reason electromagnetism does not overpower the much weaker force of gravity is a delicate balance between electrons and protons. For each electron in the universe, there is a proton, so the plus and minus electrical forces cancel each other, creating electrical neutrality. Without that balance, we could not exist.

The balance between electrons and protons is so delicate that if you were building a universe and accidentally put in one extra electron for each trillion trillion trillion electron/proton pairs (that’s one followed by 36 zeroes), it would be catastrophic. The electrical repulsion between those negatively-charged electrons would overpower the gravitational force. The result would be that gravity could not pull any mass together. If gravity could not pull masses together, there would be no planets, no stars, no galaxies. Electromagnetic repulsion would create a universe of dispersed particles and nothing else.

Each of the other forces is stronger than gravity. The weak and strong nuclear forces are confined to short distances within the atom, and the electromagnetic force is carefully balanced. Is it possible that this precision is merely an accident? Or do we see evidence of system design? We think this is one more example of fine-tuning in the universe which gives evidence of a Designer.

Programmed to Change

Colour Sergeant Butterfly - Programmed to Change
When I was a child, I was introduced to the metamorphosis of a caterpillar to a chrysalis to a beautiful butterfly. I decided to figure out how that change took place, so I cut open a chrysalis to see what was going on inside. Instead of catching the transformation in progress all I found was a capsule of black soup. Later when I asked biologists how the process took place, I realized that no one fully understood it. The caterpillar was programmed to change, but nobody could understand how.

What I did learn was that this process goes on in a wide variety of life forms. Frogs, sea urchins, flying wasps, and beetles are just a few examples of creatures programmed to change. The December 2018 issue of National Geographic features a wonderful article about the use of 3D models and micro-CT scanning of the process. These tools have given us a great deal of understanding of how this transformation occurs. The article identifies three stages of the change that happens as the caterpillar changes into a butterfly.

1. PROGRAMMED ACTIVATION. The caterpillar eats vegetation until it is full grown. As it does so, its hormones begin to shift with some parts of the caterpillar expanding and others becoming degenerate. The thoracic legs grow into legs that are good for grasping. Four wing buds on the caterpillar’s body begin to develop into wings, and the antennae become larger. The silk gland begins to degenerate to become the chrysalis. The proleg degenerates making the caterpillar more dependent on crawling. The mandible the caterpillar uses for chewing begins to degenerate making room for a tube for sipping nectar. The simple eye of the caterpillar which could only detect the presence or absence of light begins to change. All of this is programmed into the genetic makeup of the caterpillar.

2. TRANSFORMATION. As the prolegs degenerate, thoracic legs grow to adult size. Wings develop with full color from the four wing buds. The chewing mandibles morph into two halves that zip into pipes that make a straw-like proboscis. Simple eyes move forward closer to the brain and produce a compound eye which gives true vision.

3. EMERGENCE. The brain of the butterfly is almost completely rewired to meet flight requirements.  One thing that the butterfly seems to retain from its caterpillar stage is olfactory memories. It needs that to know where to produce the next generation of caterpillars. The butterfly sucks in air until its chrysalis breaks open. The butterfly flaps its wings for several hours to dry them and to circulate blood before flying off in search of a mate.

All of this happens in 15 to 21 days. The gut of the butterfly shifts from digesting plants to nectar in that short time. There are wonderful artistic drawings of all this in the article. The author summarizes his study by saying, “..the insect’s makeover is a programmed mix of destruction and growth. Certain cells die, and body parts atrophy. Meanwhile, other cells, in place since birth, rapidly expand in as little as two weeks, the adult emerges completely remodeled, capable of flight – and bent on finding a mate.”

We would add that no programming happens by chance. It takes intelligence to program a computer. The caterpillar programmed to change to a butterfly reflects the wisdom and intelligence of a great programmer superior to anything the software companies can offer.

Why Did God Create T. Rex?

Why Did God Create T. Rex?
A reader sent a question that might be of interest to several others concerning the dinosaurs. The question was if God created everything, including dinosaurs, why did God create T. rex? Why would He create a creature so violent and cruel?

Denominational creationism maintains that God created everything good and T. rex and other carnivores went bad. When man sinned, bad came into existence and creatures that had been good became bad. So dinosaurs created as good and benevolent creatures suddenly became cruel carnivores. (See Acts and Facts December 2018, page 20.)

There are so many difficulties with that explanation, it would require a book to develop them all. Our book The Source attempts to do at least part of that. You can borrow it on our doesgodexist.org website or purchase it at THIS LINK. Here are a few points:

There is no Hebrew word in Genesis (or elsewhere in the Bible) that can legitimately be translated “dinosaur.” Some suggest that “behemah” and “remes” refer to dinosaurs, but the words literally refer to cattle and sheep or goats respectively. The Israelites were familiar with these animals, and they could eat them. (See Genesis 1:24-25 and 9:1-3). Genesis was written to Israel to explain how their animals came into being. It does not include every creature that ever existed – bacteria, viruses, platypus, dinosaur, etc. It seems that Genesis 1:1 describes God preparing planet Earth for humans. To do that, God created creatures that were extinct by the time He created humans and their domesticated animals.

Material found in dinosaur feces tells us what they ate. Coprolites of T. Rex do not contain plant material. Their dental structure in all cases was made to cut meat, not to grind up plants.

Being a carnivore does not mean that an animal is bad or a monster. If you don’t have carnivores, then plant-eaters eat all the plants, and soon everything dies. Why did God create T. rex? We need carnivores with the capacity to kill and digest herbivores to keep balance in nature.

Dinosaurs were not monsters any more than lions or largemouth bass are. They were part of the balance that God used as He fashioned the Earth with the resources that humans would need. At the end of the creation process “God saw everything that He had made, and behold it was VERY good” (Genesis 1:31).

Design in Hearing

Design in Hearing
One of the amazing features of animals is design in hearing. Humans can hear sounds between 20 and 20,000 vibrations per second (Hertz). That range allows us to communicate through the air and enjoy music. Various animals can hear sounds in different parts of the frequency spectrum.

Dogs can hear frequencies higher than 20,000 Hertz. We call these sounds ultrasonic because they are above the frequencies we can hear. We use ultrasonic sounds for examining the organs inside the human body. We use it to view unborn babies inside their mother’s womb. Ultrasonic sound has uses such as cleaning of jewelry or other items. But we can’t hear it. The ability to hear ultrasonic sounds gives dogs and other animals a defense advantage. Try to sneak up on a dog. If you open a door or step on a floorboard creating an ultrasonic squeak which you can’t hear, the dog will hear and know that you are coming.

Elephants, whales, and other large animals can hear low frequencies and use them to communicate over many miles because low frequencies travel more efficiently through the ground or water. But it isn’t just large animals that use these subsonic sounds. Some small animals, like moles, can also hear low frequencies since those sounds travel well through the ground. If a mole communicated through sounds we could hear, finding and killing them would be easier for their predators and us. Because they communicate at frequencies below 20 Hertz, they are not easily detected by animals above the ground.

Design in hearing also applies to frogs, snakes, and many insects that can also hear very low or very high frequencies allowing them to communicate with others of their kind without detection by different species. Different creatures use various portions of the audio spectrum. If a creature gives off sounds that its predators can hear, they will literally be “dead meat.”

The world of sound rings out loudly the incredible design of the Creator who gave various creatures the ability to hear the sounds they need to hear. We can be thankful that God gave us the ability to hear the beautiful sounds of music and the spoken voice.

Average Star? – No Way!

Average Star? – No Way!
In the past, astronomers thought that the Sun was just an average star. After all, there are hotter stars, and there are colder stars. There are larger stars, and there are smaller stars than the Sun. If you plot the luminosity of all visible stars, the Sun falls near the middle of the system.

However, in recent years, it has become clear that the Sun is not an average star, but an extraordinary star. Without specific properties of our “oddball” star, life on Earth would not be possible. Here are just four of the many unique features of the Sun:

1-Most of the stars in the universe are binary or trinary stars. That means they are actually two, three, or even more stars orbiting each other although they appear to be a single star. A life-supporting planet could not survive that arrangement.

2-The Sun is relatively stable while most stars have much more violent flares that send out lethal radiation.

3-The Sun produces light in the proper wavelength to sustain life. Sunlight has the right wavelengths for photosynthesis and does not have the high-energy wavelengths of other stars.

4-Our Sun also has the right temperature and size to allow a large solar habitable zone where Earth can have an elliptical orbit and still support life.

There are many more “special” features that make our Sun more than an average star. If we didn’t have an above average star, we wouldn’t be here. We see our special star as another evidence that the Sun and our solar system is the work of a Master Designer.

Learn from the Animals

Learn from the Animals
We are frequently astounded by what animals can do. As science seeks solutions to problems such as having enough food, knowing how to avoid disasters, and solving medical problems, we frequently see the answers in the designed features of living things. There are many things we can learn from the animals.

How can we have enough food to feed everyone on this planet? One way is to take advantage of animals with high reproductive capacity. A female mackerel, for example, lays about 500,000 eggs at one time. We have relied on animals like cattle which have one offspring at a time, are environmentally unfriendly, and require massive energy to sustain. Many fish, arthropods and mollusks can reproduce massive numbers of offspring, need very little energy input, and give off little or no environmental hazards. Some of them even remove environmentally unfriendly materials.

Can we improve our vision and perhaps restore sight to people who are blind? Studies of the common dragonfly have shown that each eye has 30,000 lenses. Our one lens is limited as to what we can see. The way images are transmitted to the brain in animals allows multiple transmissions. We are learning from insects and chameleons how the brain can reconstruct a useful image from many separate images. A chameleon can move its eyes in different directions, and its brain can interpret the direction and identification of what each eye is seeing independently.

How can we make stronger materials? Beaver’s teeth are so sharp that Native Americans used them as knife blades. The structure of the tooth enamel in the beaver and how the teeth maintain their sharpness is an area where materials science researchers can learn from the animals.

Can we make better drones? Researchers are interested in how high-frequency wing beats can allow better control of flight. Tiny flies known as midges beat their wings over 1000 times a second – twice as fast as mosquitoes. We can even learn from the animals that are almost too small to see.

Examples like these challenge those who would attribute animal design to chance processes and survival of the fittest. The design engineering in the animal world suggests wisdom beyond that of humans. In Proverbs 8:5,22,35 wisdom speaks, “O you simple ones understand wisdom and you foolish ones, have an understanding heart. The Lord possessed me (wisdom) in the beginning of His way, before His works of old. For whoever finds me finds life and shall obtain the favor of the Lord.” Let us be wise as we copy the wise designs of the Creator.

Springs of the Sea

Springs of the Sea
On the floor of the oceans of the world, hydrothermal vents are spewing superheated water. We could call them springs of the sea.

These ocean vents send out water at temperatures that are much higher than the temperature at which water boils under normal atmospheric pressure. The sea vents are usually called “black smokers” or “white smokers” depending on the minerals that are contained in the water they release. Those minerals nourish various sea life in the area. The white smoker in the picture is in the Marianas Trench Marine National Monument in the Pacific Ocean. It is emitting barium, calcium, and silicon as well as carbon dioxide.

The hydrothermal vents are primarily along the mid-ocean ridges which are formed by tectonic plates that are moving apart (diverging). Tectonic plates are massive sections of the Earth’s crust which move relative to each other diverging, converging, or transforming in various ways. It’s along the boundaries of those plates that most earthquakes and volcanic activities occur. As the plates diverge along the ocean ridge, they move outward and subduct (move under) other plates. This subduction forms trenches which are the lowest areas of the ocean floor.

It was only in 1977 that scientists from the Scripps Institution of Oceanography discovered sea vents by using a submersible owned by the Woods Hole Oceanographic Institution. It’s interesting to note that the Bible in Job 38:16, written 4,000 years ago, records God saying to Job, “Have you journeyed to the springs of the sea or walked in the recesses of the deep?” We now know that there are “springs of the sea” (hydrothermal vents) and “recesses of the deep” (trenches) in the ocean. Of course, since God created them, He knew it long before we did.

Honeybee Clusters – How They Survive

Honeybee Clusters
Among the most interesting things to see in the natural world are honeybee clusters. When bees search for a new location, the queen will move to a tree branch or some other surface she can hang onto. The worker bees cluster around her making a large ball. Researchers have noticed that the ball of bees changes shape as various forces like wind or vibration are directed at it. The changing shape fine-tunes the cluster to resist the elements protecting the queen and the cluster as a whole. The question is how the bees know where and how to move to hold the ball together.

Researchers at Harvard University have found that the strain sensed by each bee is the answer. When a bee feels stress from the wind or some other external force, they will move to an area of greater strain. Many bees moving to protect the cluster flattens the cluster’s shape making it more resistant to the source of the stress. The bees are taking more strain on themselves for the good of the cluster.

In fundamental physics, we know that Young’s modulus is the ratio of stress to strain and every material has a value. Understanding the values is critical to engineering structures to prevent material failure leading to the collapse of the structure. Apparently, bees have a high Young’s modulus designed into their genetic makeup to allow the honeybee cluster to survive.

Researchers emphasize that our understanding of insect behavior is in its infant stage. As concerns grow over the loss of bees that are important pollinators, more research is of great importance. Our understanding of God’s designs in the natural world continues to grow. The complexity of even such simple things as honeybee clusters tells us we have a lot to learn. It also tells us much about God’s wisdom and engineering design.

Can’t Get That Song Out of My Head

Can't Get That Song Out of My Head -Yellowhammer Singing
Have you ever had a song stuck in your head? Sometimes we hear a song, and it seems to keep ringing in our brains for days. It may be a song we love. Sometimes it’s an annoying song that we can’t stand but can’t forget. Advertisers often use jingles in their commercials hoping that their little songs will keep haunting us until we buy their products. Whether good or bad, I can’t get that song out of my head.

I can be thankful that whatever the song is, it will eventually go away–and be replaced by another one. Imagine what it would be like if you had only one song for your whole life. More than that, imagine that your children and future descendants still had that same song. That could be the description of the life of a songbird.

We love to hear songbirds, and with a little effort, we can learn to identify different species of birds by their songs. That’s because, for the most part, each species has its unique song that it passes on from generation to generation.

Songbirds are born with a song stored in their brains. As the birds grow, they learn to match their vocal patterns to the song in their heads. Even if a baby bird never hears its parents sing, and although surrounded by the songs of other species, it will still learn to sing the song that its parents sang. There are a few species of birds that can imitate the songs of other birds, or even human voices and other sounds. Those birds are born with a different program built into their brains that gives evidence of a creative Designer of life.

When I can’t get that song out of my head, I can start singing or listening to a different song. Humans have that ability because the Designer has given us a creative capacity. That’s part of being created in the image of a creative God. But what if all people made their houses precisely the same way? Besides singing the songs of its parents, a bird will build only the same kind of nest its parents made. You would have to say that Someone also stored the nest-building instruction book in the bird’s brain.

Is it possible that an intelligent Designer drew up the nest plans and created the songs and placed them in the bird’s DNA? Generation after generation, the song and nest data are pre-programmed for the birds to follow. Remember that the One who drew the nest blueprints and wrote the songs and programmed them into the tiny brains of those birds is the One whose, “eye is on the sparrow” and furthermore, “I know He watches me.” (Matthew 10:29-31)

Beneficial Fungus Called Smut

Beneficial Fungus Called Smut
Those of us who have grown sweet corn have almost always had to fight smut. That black and gray growth on corn looks disgusting. It is actually a fungus known scientifically as Ustilago maydis, and it has been around for a long time. Even though we dislike it, in some ways smut is a beneficial fungus.

Archaeologists studying ancient Puebloan people have found significant amounts of corn smut spores in their feces. That indicates that maize (corn) made up as much as 80% of the diet of ancestral Puebloan people and it included a great deal of the fungus.

One of the mysteries of ancient peoples in America is why they didn’t have nutritional diseases that were common in the world at that time. The most serious of those was the skin disease pellagra which is caused by a lack of niacin (vitamin B3) in the diet. The amino acid that prevents pellagra is missing from the maize but is present in high concentrations in the smut.

We generally have a negative attitude toward fungi, but there are many examples of beneficial fungus. Remember that penicillin was derived from a fungus. Now we find corn smut also offers a benefit. God has a use for everything He created, but sometimes it takes us a while to figure out what that use is.

We have a children’s book about beneficial fungi, and you can see it online HERE.
