It’s Good to be Blue

It's Good to Be Blue Begonia Leaf
It’s a plant that uses quantum mechanics to make maximum use of minimum light, and in doing so, it displays blue leaves. The explanation of why blue begonias are blue is another demonstration of the incredible design built into all living things.

The tropical begonia (Begonia pavonina) that grows in Malaysia has leaves that are iridescent blue. The blue does not come from pigmentation, but rather from structural color, a technique that gives beautiful color to some birds, Butterflies, and beetles. In the leaves of all kinds of plants there are cellular capsules called chloroplasts, and inside those structures is a green substance known as chlorophyll. The chloroplasts are the organic machines that take energy from sunlight and chemicals from the soil to make organic energy that allows the plant grow.

Sunlight is a mixture of light at various energy levels, but green is the highest energy of sunlight reaching the surface of the Earth. Since the chlorophyll pigment reflects green light, the plant is protected from being damaged by the high-energy sunlight. We see the reflected green light, so the leaves look green.

Blue begonias live on the floor of dense rain forests where the forest canopy restricts the light. Inside the chloroplasts of these begonias, there are nano-structures called thylakoids where the energy conversion takes place. Other plants have thylakoids, but they are arranged differently in the begonia. Scientists using an electron microscope discovered that the thylakoids are aligned in a way that they act like crystals. In other plants, they are haphazard in their arrangement. Light bounces around within the thylakoids causing interference at certain wavelengths and reflecting the iridescent blue. The light is slowed down in this process so the plant can use more of the high-energy green and red light while reflecting the blue. These plants are using principles of quantum mechanics which scientists only began to learn about in the twentieth century.

The result is that the blue begonias get the nutrition they need to survive in a location with little sunlight, and we see the leaves as a beautiful blue. One science website described the alignment of the thylakoids in this way: “…they have an amazingly regular structure, which is obviously planned.” Here is the way another science website described the unique way these begonias efficiently use the limited sunshine they receive: “It seems selective evolution led the plants to engineer a nanoscale light-trapping structure, the likes we’ve only seen in miniature lasers and other photonic structures made by humans…”

We believe that planning requires a planner and engineering requires an engineer. As scientists study even the simplest forms of life, they find more and more evidence that God is ingenious in all He creates.

Saharan Silver Ants

Saharan Silver Ants
The survival of living things in extreme conditions is always fascinating. There are places on Earth, such as the Sahara Desert, where the temperature on the ground can soar to 120 degrees Fahrenheit. Even in that extreme heat there are living things functioning very well in conditions that would be lethal to most forms of life.

Extreme survival is a way of life for the Saharan silver ants (Cataglyphis bombycina). The predators of these ants are desert lizards that retreat into their burrows in the heat of the day. Some of the ants keep watch to let the others know when the lizards are gone. Then the ant colony makes its food-search expedition. They come out into the full Sun and intense heat to scavenge animal carcasses. The picture shows them devouring an engorged camel tick.

The question is, “How do they survive the heat?” They have longer legs than most ants, and that keeps their bodies farther from the hot sand. They also travel across the sand at high speed (2.3 feet or 0.7 meters per second) using only four of their six legs to keep fewer feet on the ground. Also, their bodies produce heat-shock proteins that help their cells cope with the stress of the high temperature. Many animals produce heat-shock proteins, but not until they are exposed to extreme heat. The Saharan silver ants are programmed to produce those proteins before heat exposure to prepare them for what’s ahead.

Even with those adaptations, they are still exposed to the direct rays of the Sun. Scientists used electron microscopes to find the secret of the Saharan silver ant’s survival. The ants are covered with microscopic hairs that are not round or oval in cross-section like most hairs. They have a triangle shape to act as prisms. This shape reflects both the visible and infrared (heat) energy from the Sun away from their bodies. Because of these tiny prisms, the ants display a metallic shine. They look like metallic beads rolling quickly over the desert sand. No other desert creature has this form of reflection. Saharan silver ants are among the most heat-resistant creatures in the world.

Like many things in nature, engineers are looking into how we can imitate the prism method of these ants to protect humans from the dangers of extreme heat. Designing something that can reflect the heat this efficiently requires a deep understanding of optics and the nature of light and heat energy. The wisdom of the Creator shines brightly in the reflected light coming from the Saharan silver ants.

Space Dimensions and Lunar Motion

Space Dimensions and Lunar Motion
We have had several questions and comments precipitated by the eclipse on August 21. Most of them centered around the fact that the Moon’s motion across the Sun was so slow. In reality, the lunar motion is very fast. The speed is a function of the Earth’s rotation as well as the Moon’s revolution around the Earth. However, when compared to space dimensions, lunar motion can seem slow.

The Moon moves with an orbital speed of 2,288 miles (3,683 km) per hour, taking about 28 days to complete its journey around the Earth. Although that sounds fast, it is quite slow in relation to the size of the cosmos. Other moons going around other planets travel at higher speeds. Io, one of the moons of Jupiter, whizzes completely around the planet in less than two days. While our Moon travels at the speed of a rifle bullet, it is 80 times slower than the speed of meteors. Saturn travels ten times faster than the Moon.

The reason we are not aware of the speeds involved is because of the incredible size of the creation. We see meteors moving fast because they are close to us. Meteors are pieces of space junk whizzing through our atmosphere so quickly that they burn up from friction with the air. The moon is over 239,000 miles (384,633 km) away, so its motion appears to be much slower.

When we look out into the night sky, we are looking far into the past. By the time we see the light from stars like Albireo, that light has traveled 430 light-years. That star is actually two stars spinning around each other. Even though they are orbiting each other and astronomers have been watching them since the seventeenth century, we have not seen them change position.

Space dimensions are beyond our comprehension, and the size of the cosmos affects what we see and how we see it. Understanding that should give a whole new significance to the words of the song How Great Thou Art. It should also expand our understanding of, “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalms 19:1).

Apes and Humans

Apes and Humans
Is there an evolutionary connection between apes and humans? Many years ago in a youth rally, a young lady asked me, “If we didn’t come from apes, how come my brother looks so much like an ape?”

It is true that we share many physical characteristics with the apes. Apes and humans both have stereoscopic vision, necessary for depth perception. We both have opposable thumbs, necessary to hold a tool or a club. Apes and humans have noses immediately above our mouth to detect and analyze flavor. Naturalists who want to explain everything on a chance basis suggest that apes and humans share a common ancestor.

Those naturalists frequently ignore the fact that there are many things humans do not share with apes. These are not physical characteristics, but they are what separate us from all other forms of animal life. They include our capacity for worship and our ability to create music and art. Only humans have the ability to think and reason in abstract terms. Apes do not share our capacity for guilt and sympathy, including our ability to have an “agape” kind of love that isn’t survival based.

We would think that with our genome being so similar to the apes some of these characteristics should show up to some degree in the apes. In spite of attempts to show such connections, it is increasingly obvious that such attempts are complex exercises in anthropomorphism.

The question then is, “Why do we see such an enormous collection of fossils of primates which is expanded daily by paleoanthropologists?” In The September 2, 2017, issue of Science News Bruce Bower reviewed some of the evidence and current theories about ape evolution.

The bottom line is that there are connections between specimens like oreopithecus, modern day gibbons and recent finds like Nyanzapithecus alesi. The capacity of life-forms to change is a fact that no one can deny. The various races of human beings indicate that humans have changed enormously since the beginning. The Bible tells us about our human spiritual nature, and that nature has not changed throughout our history. Our physical makeup has changed a great deal during that time, and apes have changed even more.

We see humans as a special creation of God–created in His image with characteristics that are not a product of physical changes. As scientists find more fossils of apes, they will study the changes that have taken place leading to the wide variety of monkeys and apes in the world today. They will create more theories about the physical evolution of apes. In spite of that, the special place of humans in relationship to God will remain unchanged. How we should treat other humans with love and compassion will also not change.

Why Is There Color in Our World?

Why Is there Color in the World?
One of the joys of life is the beauty that we see in the natural world. The beauty of flowers is so great that we decorate our homes inside and out with flowers of every description. People will get out of bed early in the morning to watch a sunrise display colors of incredible beauty and complexity. We admire the work of artists and photographers who can capture a permanent record of the colors of the world on canvas or film. Why is there color in the world?

There are hundreds of papers that have been written by scientists and science writers concerning the reason for color. The design of the Earth and of the life systems on Earth frequently demand that certain colors exist. For example, the green in vegetation is necessary to protect plants from the high energy wavelengths of the Sun’s light.

There are some colors in the natural world, however, that seem to defy a naturalistic evolutionary explanation. Flowers living in identical environments will frequently have radically different colors. If we postulate that the colors are different to attract different pollinators, we run into logical problems. Wouldn’t the most efficient pollinators provide the same advantages to all flowers of similar geometric design? In caves deep in the ocean, there are some of the more vividly colored tropical fish. These fish never see sunlight and have no camouflage advantage given by their colors. There are worms and burrowing animals in thermal vents deep in the floor of the ocean that display rich and beautiful colors.

A skeptic may reply that these colors are a chance consequence of the materials that make up the bodies of these organisms. The fact is that, in many cases, the colored materials in the organism are inconsequential to the survival of the organism. We would suggest an equally plausible and perhaps more realistic explanation. Could it be that a God of intelligence and creative power designed the creation not only with functional wisdom but also with aesthetic intelligence?

Why is there color? God obviously enjoys beauty. We were created in God’s image, and therefore we enjoy the beauty of the world around us. Beauty is one of the things that makes our sojourn on this planet worthwhile.

Nursing Orangutans and Evolution

Nursing Orangutans
As scientists study different animals in their natural environment, they frequently learn things that complicate accepted pictures of animal history. A recent series of studies of nursing orangutans in Borneo and Sumatra has shown that weaning doesn’t occur in these animals until they are more than eight years old. That is a record lactation period for any wild animal.

Determining the length of nursing for orangutans has been difficult for various reasons. For one thing, the nursing takes place high in the trees, so scientists have difficulty observing. Add to that the fact that these animals are hairy, so it becomes difficult to see what is going on. Some have suggested that the babies are just cuddling.

Researchers finally settled the question by studying orangutan teeth. Studies of the layers of material containing barium in the teeth of the babies indicate that they really are feeding. Museums have collections of orangutan teeth from years ago when these animals were not considered to be endangered and were often killed by collectors. Calcium and barium from the mother’s body go into building the nursing infant’s teeth. Primate teeth are built up with a microscopic layer each day. By examining the layers, scientists can tell when the infant orangutan stopped nursing because there is a greater concentration of barium in the nursing layers. Examining teeth from orangutans at different ages, the scientists determined that nursing can continue through age eight.

Some evolutionary theories have difficulty with these very long lactating periods. Not only is the female not receptive to males during that eight years, but she must continue to produce milk. In milk production, the mother is literally dissolving some of her body to provide nourishment for the young. These two factors seem to be counter to evolutionary models for survival. These new discoveries concerning nursing orangutans may cause some rethinking concerning theories of primate evolution.

Origin of Life Problems Admitted

Wing Challenge to Origin of Life
One of the more honest and fair writers in modern scientific publications is Dr. Bob Berman. He has a regular column in Astronomy magazine and an interesting website. In the September 2017 issue of Astronomy (page 10), he has an outstanding brief review of the problems involved in trying to explain the origin of life. He begins by pointing out that the definition of “life” has been an issue because of questions such as whether or not a virus is alive. Viruses have no metabolism, they don’t feed or breathe, and yet they reproduce.

Berman then reviews some of the parameters necessary to consider when addressing the origin of life. Chirality is a major issue because amino acids that make up proteins come in right- and left-handed versions. Life on Earth is made up of only left-handed amino acids. Sugars used by the proteins are limited to the right-handed direction, and so is DNA. The wrong chirality just will not work to support life, so how could nature sort out the chirality? If life is easy to produce, why don’t we see it coming into existence all over the Earth? The “amoeba-to-man” model assumes that it only happened once, which conflicts with the view that life is abundant in the cosmos.

What is especially interesting is that Berman raises questions about the ability of evolution to explain on a chance basis some of the designs we see in living things. He uses the example of the airfoil that all flying forms of life have. The upper surface is convex using the Bernoulli effect to produce lift. The earliest bird and the flying reptiles all had a wing design that works. Trial and error would not work well to explain how the wing design would come into existence by chance. Berman points out that “some 400,000 cells would all have to simultaneously mutate in just the right way to create a properly shaped wing. This defies an evolutionary hypothesis.”

Berman concludes with the statement, “I’m not invoking spirituality, merely that the effect of random collisions and mutations is not always a workable answer. So perhaps nature is inherently smart.” I would suggest that wing design is just one of a massive number of design features that allow life to exist.

Berman quotes Francis Crick, the co-discoverer of DNA’s double helix as saying that the origin of life is “almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.” We don’t invent a “god” to explain these things, but we would point to these things as one more evidence that there is a God and that blind chance is not a good designer of the complexity we see in the world around us.

Next Total Solar Eclipse 2024

The Next Total Solar Eclipse
The total solar eclipse of 2017 is now history. If you were in the United States, you probably saw at least a partial eclipse. If you missed the totality, you will have another chance in about seven years. The next total solar eclipse visible in North America will be on April 8, 2024.

The eclipse of 2024 will travel from south to north. After traveling across Mexico, it will cross the US border in Texas. It will travel northeast to follow the length of Lake Erie. Then it will skirt southern Canada and northern New England. It will leave the United States when it crosses Maine before crossing New Brunswick and Newfoundland and disappearing in the North Atlantic. Major US cities within the band of totality will include Dallas/Fort Worth, Indianapolis, Cleveland, and Buffalo. Although the 2017 eclipse was total for only about 2.5 minutes, the 2024 eclipse will last about 4 minutes in totality. You can get more details about it here.

However, the eclipse of 2024 will not be the next total solar eclipse in the world. Before 2024 there will be other total solar eclipses and partial eclipses in other parts of the world. You can find information about upcoming solar eclipses here and here. You will see the dates and times for solar eclipses up to the year 3000!

How can we predict solar eclipses with such precision, even hundreds of years in advance? The reason is that God has designed a solar system with stability and precision. Those factors also make possible the abundant life on this planet. Design, not chance is evident in the wisdom of creation.

Just Right Moon

Solar Eclipse Thanks to Just Right Moon
In a few days, a total solar eclipse will cross the full width of the United States, and you can give credit for that to the just right moon.

We have looked at the “how” and “why” of total solar eclipses. We have considered what value total solar eclipses have. We have seen that a total eclipse helped to confirm a very important scientific principle. Also, we pointed out that solar eclipses happen only at the time of the new moon when the Moon is between the Earth and the Sun.

A new moon occurs about every 29 days, so why doesn’t an eclipse happen at each new moon? That’s because the plane of the orbit of the Moon around the Earth is about five degrees off from the orbital path of the Earth around the Sun. Because of that difference, a solar eclipse happens only when the Moon crosses the path of Earth’s orbit around the Sun (called the ecliptic). A TOTAL solar eclipse happens only when the Sun and Moon are exactly aligned.

What would happen if the orbit of the Moon were on the same plane as the ecliptic? At every new moon we would have a total solar eclipse, and at every full moon, we would have a total lunar eclipse. So the Sun would go dark in the daytime somewhere on Earth every month, and the full Moon would also go dark monthly. The influence of the Sun’s gravity on the lunar orbit might cause more serious problems.

No other planet has a moon that plays such an important part in creating an environment suitable for life. The Moon is right where it should be to serve life on Earth. Our just right Moon lights the night, creates the tides that clean our estuaries, stabilizes Earth’s rotation, and occasionally provides a total solar eclipse that gives us a glimpse of God’s marvelous design of our solar system.

The Value of a Total Solar Eclipse

Albert Einstein and the value of a total solar eclipse
Here is an interesting story of how a solar eclipse helped to confirm a scientific theory and demonstrated the value of a total solar eclipse.

Yesterday, we pointed out that it’s more than a “marvelous coincidence” that the Moon can exactly block our view of the much larger Sun. It’s an evidence of design. When the Moon hides the Sun’s photosphere, scientists can study the chromosphere and the corona to learn more about the Sun and how it affects life on Earth.

In 1687 Isaac Newton presented his universal law of gravitation answering many questions about gravity. One question that remained unanswered was how gravity can act through empty space.

In 1916 Albert Einstein presented his theory of general relativity in which he proposed that mass produces gravity by warping space. Planets orbit the Sun because the mass of the Sun and the planets causes space to be curved. The theory suggested that light would also follow a curved path because of this warping. Einstein calculated how much light would bend near a massive object and proposed that light from distant stars would be bent when it passes by the Sun.

Einstein’s idea seemed hard to believe, but there was no way to disprove it since the bright Sun hides any starlight passing near it. You can’t see the stars during the day.

Then in 1919, British astrophysicist Arthur Eddington made some measurements during a total solar eclipse. While the Moon blocked the Sun’s photosphere, Eddington made precise measurements of the apparent position of stars that were visible near the Sun. Comparing those measurements with the positions of the same stars at night, he confirmed that Einstein was correct. The light was bent as it passed by the Sun.

The eclipse of 1919 demonstrated the value of a total solar eclipse. Many eclipses since then have added to our scientific knowledge. Understanding how gravity warps space has allowed us to make accurate Global Positioning Satellites. We use GPS in our cars for driving, in our tractors for farming, and in our smartphones for hiking, and for many other things. God designed and engineered an amazing world and gave us the ability to understand it through scientific study. Science and faith are friends–not enemies.
