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.

Death and Taxes

Death and Taxes

You have heard people say that nothing is certain but death and taxes. That isn’t entirely true. It is true that every one of us will face physical death. More than that, every government that collects taxes will also die. It’s a scientific fact that all things, even the universe itself, will come to an end. There is no escaping death for everyone and everything.

The second law of thermodynamics tells us everything in the universe is becoming disordered. The disorder will eventually catch up with us and with everything else. Our vehicles wear out. Our clothing wears out. Our bodies wear out. Even the Sun and all of the other stars will wear out.

If you spend your life getting all you can for yourself, not caring whom you hurt in the process, you will not take your riches with you. If you spend your life doing good and helping others, those you helped will also die, and the monuments you built will crumble. If you devote your life to studying science and adding to the database of human knowledge, that too will go away. If all things in the universe, including humans, are merely accidents of chance, we ultimately have no purpose, no value, and no hope.

If you have read this far, you may be feeling depressed, but I have good news. There is a God who created the universe, and you, for a purpose. Yes, your body will die, and even the universe will die. But by God’s grace, you can choose to live on. God has entered the time dimension in human form and conquered death for us. Jesus said, “I am the resurrection and the life. Those who believe in me, though they die, yet shall they live.”

How is it possible to live beyond death? In the beginning, God created time and space, matter, and energy. Those things do not limit Him because He created them. The second law of thermodynamics does not apply to God. He does not get old or die. The Bible tells us that because of God’s love and grace, you have the choice to believe and accept and live with God in a new creation. Yes, you can live beyond death and taxes. The choice is yours.

A Flower or a Weed?

Daisy - A Flower or a Weed?
This wildflower can be found growing in fields and meadows. Its soft petals and yellow core make it universally recognizable. Many related plants are called daisies, but the common daisy (Bellis perennis) is native to Europe and is sometimes called the English daisy due to its native location. However, daisies have become so prevalent around the world that some say they make up almost 10% of all flowering plants on Earth. This leads to the question of whether it’s a flower or a weed.

The name “daisy” comes from “day’s eye” because the head closes at night and opens with the sunrise. You may look at the common daisy and believe that the head is a solo flower. In reality, it’s a composite flower made up of a cluster of flowers called an inflorescence. Each inflorescence grows on a single, leafless stem with rounded leaves growing from the base. Common daisies resemble another wildflower known as chamomile. However, chamomile has multiple flower heads growing on the same stalk.

Common daisies are robust and can thrive in many different types of soil, in full sun or partial shade, as long as minimum temperatures remain above -30 degrees F (-34 C). They grow on every continent except Antarctica. Daisies can grow in practically any valley, meadow, or field. If the conditions are right, daisies will populate themselves in enormous numbers engulfing the ground like weeds. A meadow full of daisies is a beautiful natural scene. However, in some areas, they are considered to be invasive weeds. In fact, they are so hardy they may crowd out noxious weeds. So is it a flower or a weed?

Daisies are beautiful to look at, but they can also be beneficial in other ways. Daisies can help improve the biodiversity of the household garden by attracting pollinating insects as well as birds that feed on the insects. Young daisy leaves can be added to salads, and they supply vitamin C. The buds and petals are also edible in soups or salads. Some people have also used them for treating gastrointestinal disorders. Children use them to make daisy chains, and young women count the petals to the refrain “he loves me; he loves me not.”

So the question of whether it’s a flower or a weed depends on your perspective. We prefer to think of them as flowers. Whether wild or cultivated, we find the number and variety of flowers in the world amazing. Apparently, God loves beauty, and He has given humans the ability to enjoy it also. After all, the Creator made us in His image.

Zoopharmacognosy Animal Doctors

Zoopharmacognosy Animal Doctors Zoopharmacognosy is a word you don’t see every day. It’s actually a combination of three Greek words which mean “animal” (zoo), “drug” (pharma), and “knowing” (gnosy). It refers to animals using plants, soils, insects, or drugs to solve specific medical problems. It is animals (not humans) medicating themselves. Mammals, birds, and even insects use zoopharmacognosy to cure medical problems, and sometimes to prevent them. Here are a few examples.

It is fairly common to see a sick dog or cat eating grass to induce vomiting.

Sick chimpanzees swallow bitter leaves of Aspilia, a plant that contains an anti-parasitic chemical. The leaves are covered with bristles and bitter tasting so the chimps roll up the leaves and swallow them whole like we might take a pill.

Others chimps and bonobos with diarrhea will split open the stem of an Aframomum plant and suck the bitter juice. The juice contains chemicals which kill parasites which cause diarrhea.

Spider monkeys in Brazil have been seen eating seed pods from a tree known as monkey ear or elephant ear (Enterolobium cyclocarpum) during mating season. The fruit contains progesterone which promotes female fertility.

Brown bears make a paste from the chewed roots of osha (Ligusticum porteri) mixed with saliva and rub it into their fur to repel insects and soothe the bites. The plant contains coumarins which repel fleas and ticks.

To get rid of lice, many songbirds with put ants on their feathers or even roll in an anthill. The ants secrete formic acid, which kills feather lice.

Ants infected with Beauveria bassiana, a soil fungus, will eat harmful substances that are antifungal.

Many kinds of animals will eat dirt to absorb toxins, to combat parasites, or as an antacid. Sometimes they eat dirt to supplement minerals that are missing in their diet.

Pregnant elephants will chew the leaves of a specific tree in the Boraginaceae family to induce labor. Kenyan women make tea from those leaves to help with childbirth. In many cases, people have learned medicines and tonics from animals.

There are many more examples of zoopharmacognosy in which animals act as their own doctors. How did animals get this knowledge? It seems to be instinctive, not learned. Perhaps this instinct was put within the genetic code of these animals by their Creator.

Saguaro Desert Old-Timers

Saguaro Desert Old-TimersThe saguaro (pronounced suh-wah-roh) cactus is found only in the Sonoran Desert areas of southern Arizona, northern Mexico, and a small area of southeast California. We call them saguaro desert old-timers for a good reason. Saguaros grow very slowly as a single stem for perhaps 75 years before developing arms. Plants with five arms may be 200 years old.

Saguaro flowers bloom at night from April to June. They close by noon the next day, never to open again. Saguaro flowers can only be fertilized by cross-pollination so there must be a creature to carry pollen from one plant to another. Because the flowers bloom at night, bats are the pollinators. They drink the nectar and transfer pollen from plant to plant.

A successfully pollinated flower will produce a green, oval-shaped fruit with bright red pulp. Many desert creatures eat the fruit and aid the saguaros by spreading their seeds. Only a small percentage of the seeds will ever germinate, but that’s okay because each flower produces as many as 4000 seeds.

Not only do the saguaros have a symbiotic relationship with the bats which consume their nectar and the many creatures who consume its fruit, but it also provides shelter for many desert animals. Saguaros become apartment houses for birds, lizards, desert rodents, and reptiles, as well as a whole entourage of insects.

Saguaros are remarkably well-designed for life in a dry climate. The outside of the plant has pleats like an accordion. The pleats allow expansion for storing large quantities of water when the rains come. As with other cacti, the saguaro has needles rather than leaves to reduce the loss of moisture by transpiration.

Saguaro desert old-timers are designed in a marvelous way to live in the harsh conditions of the desert while providing food and shelter for various desert creatures. They are another indication of a Master Designer of life.

Romantic Get-Away Inside a Sponge

Venus flower basket
The Venus’ flower basket (Euplectella aspergillum) is a deep ocean sponge with fascinating properties and an unusual symbiotic relationship with a pair of crustaceans. We call it a romantic get-away inside a sponge.

The Venus’ flower basket is classified as a glass sponge because its body is made of silica, which is chemically the same as glass. The silica fibers are woven together to make a hollow, cylindrical vase-like structure. The fibers form a fine mesh which is rigid and strong enough to survive deep underwater. The picture shows a Venus’ flower basket more than 8400 feet (2572 meters) under the ocean’s surface.

Glassy fibers thin as a human hair but more flexible and sturdier than human-made optical fibers attach the sponge to the ocean floor. The sponge forms the fibers at ocean temperatures while human-made glass fibers require high-temperature furnaces to melt the glass. Human-made fibers are brittle while the sponge’s fibers are more flexible. Scientists are studying these sponges to find ways to make better fiber-optic cables.

We think it’s amazing that the Venus’ flower basket lights its fibers using bioluminescence to attract prey. Even more interesting to us is the symbiotic relationship these sponges have with some crustaceans called Stenopodidea. The Venus’ flower basket holds captive two of those small shrimp-like creatures, one male and one female, inside the sponge’s hollow mesh tube. The captive creatures clean the flower basket by eating the tiny organisms attracted by the sponge’s light and consume any waste the sponge leaves. The sponge provides the crustaceans with protection from predators.

As the crustaceans spawn, their offspring are small enough to escape from the basket and find their own sponge-home where they grow until they are trapped. Because a pair of crustaceans spend their lives together inside the sponge, Asian cultures sometimes use a dried Venus’ flower basket as a wedding gift to symbolize “till death do us part.”

The Venus’ flower basket and the crustaceans benefit each other by mutual cooperation, which we call symbiosis. One more thing, the bioluminescence comes from bacteria that the sponge collects. This amazing three-way partnership occurs deep under the ocean where humans have only recently explored. We think this romantic get-away inside a sponge is another evidence of Divine design, not chance mutations.

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.

Does God Cause Disease Outbreaks?

Does God Cause Disease Outbreaks?In 1347, history’s worst disease outbreak began when the bubonic plague, or “black death,” spread across Europe. In the following years, one-third of the human race died from that disease. Five-hundred years later in 1847, a cholera outbreak threatened London. In one year, 72,000 people died. These events bring up some questions. Can we blame God for these tragedies? Does God cause disease outbreaks? Do these plagues prove that God does not exist, because a loving God would not have allowed them to happen?

An Italian doctor first presented the concept of germs in 1546, but the idea was not proven and accepted until the late nineteenth century. During those hundreds of years, there were more outbreaks of the plague, cholera, and other diseases. Very slowly, people began to realize how to prevent these deadly outbreaks. The answer was in proper disposal of sewage, prompt and proper burial of the dead, cleanliness and washing, and quarantine.

It seems obvious to us today, but it took centuries for humans to discover those secrets. Actually, they were not secrets at all. Thousands of years earlier they had been revealed in a book. Dispose of sewage properly—Deuteronomy 23:12,13. Bury the dead promptly; avoid touching dead bodies; clean and wash with water, ashes, and hyssop (which contains the antiseptic carvacrol); and quarantine—Deuteronomy 21:23; Numbers 5:2, 3; Numbers 19:1-22; Leviticus 13:45, 46. Those instructions were written in the first books of the Bible by Moses, a man trained in the customs of Egypt for 40 years.

So did Moses learn this from the Egyptians? Absolutely not! Ancient Egyptians mummified dead bodies with their bare hands and then spread the germs around to others. Even Moses admitted that there were “horrible diseases” in Egypt. (See Deuteronomy 7:15.) How did Moses have this life-saving information 3500 years ahead of his time? We think that God revealed it to him.

Does God cause disease outbreaks? Does God enjoy hurting people? The answer is NO. Think of how many lives could have been saved in those three-and-a-half millennia if people had just followed the teaching of the Bible.

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.

Unique Spiders with Amazing Speed

Unique Spiders with Amazing SpeedOne of the evidences for God is the specialized design features built into living organisms. There are indications of design and intelligence that are difficult, if not impossible, to explain by chance. There are about 35,000 named species of spiders, but scientists are still discovering more unique spiders.

Spiders have many features that allow them to provide balance in the natural world by eating insects which would otherwise pose a threat to all life on Earth. Spiders capture their prey in various ways. We usually think of spiders making webs. Most of them do, but not all. Many unique spiders use other tactics to grab insects, while the ones that make webs use a variety of shapes and patterns in a variety of locations. Even the way they use their webs varies.

One family of spiders called ray spiders (Theridiosomatidae) make cone-shaped webs. But even ray spiders don’t all use their cone-shaped webs in the same way. In the Peruvian Amazon, there is a ray spider that weaves a cone and attaches a single strand of silk to its tip. The spider reels in the strand to put tension on the web. Instead of waiting for an insect to fly into the web, this spider takes a more proactive approach. When an insect flies in front of the cone, the spider releases the single strand. With the tension released, the web shoots out with the spider riding the tip of it like a slingshot. The helpless insect gets nabbed in mid-air. For obvious reasons, this spider is called the slingshot spider.

The tip of the cone with the spider attached reaches the target with amazing speed before the insect can escape. Scientists have measured the acceleration of the spider riding the slingshot at 100 times the acceleration of a cheetah, the fastest land animal on the planet. As far as unique spiders, we believe that the slingshot spider holds the title of world’s fastest spider.

This spider creates a very complex and well-designed food-collecting tool. The spider must make the cone in exactly the right shape, and with the right chemical make up of the strands for elasticity. Who taught the slingshot spider this amazing trick and gave it the physiology needed to carry it out? We see God’s design and chemistry in everything from the atom to the universe to every living thing on Earth, including unique spiders.
