Space Debris: A Growing Concern

Space Debris: A Growing Concern to Astronauts in SpaceA significant issue for the future is our total lack of care for the planet on which we live. We not only have the problem of plastic waste and carbon dioxide emissions, but now we have the issue of space debris.

From 1957 when the space age began, until January of 2019, humans have placed nearly 9,000 satellites in Earth orbit. More than half of them, around 5,000, are still in orbit, and 1,950 are still functioning. In addition to the satellites, there is debris from all this activity. The European Space Agency tells us that there are 130,000,000 pieces of debris larger than .04 inches in orbit around Earth. The number of articles between .4 inches and 4 inches is 900,000, and 34,000 are 4 inches or larger.

What all of this space debris does to Earth’s neighborhood is becoming a concern to scientists. It creates a danger of collision with operating satellites or crewed spacecraft, such as the International Space Station. That danger becomes especially apparent when you realize that space debris can be traveling at speeds up to 17,500 miles per hour (28,100 km/hr). The threat obviously increases as we continue to orbit objects of all kinds, leaving more junk in space.

Why is it that we have to have a tragedy to make us realize the importance of being good stewards of what God has created for us? God gave us the responsibility to take care of the Earth, and He has not rescinded that duty as we develop new technology.

Care and Maintenance of Pets

Care and Maintenance of PetsI am totally in awe of how much pets mean to people and how much they do for their owners. As people become more and more aware of the need to take care of planet Earth, they realize the environmental impact of the care and maintenance of pets.

When God created life on this planet, He built balance into all life. There were natural limits to the population of animals. There was a healthy relationship between prey and predator. Then humans killed off certain predators and transported animals to new areas where they had no predators. They sometimes adopted wild animals as pets and later released them or allowed them to escape into the wild. Those actions upset the balance, and today we are paying the price for that disturbance.

The United States Fish and Wildlife Service tells us that cats, many of them feral, kill billions of birds every year. The International Union for the Conservation of Nature reports that wild and free-roaming dogs are a threat to the survival of almost 200 species around the world. Sometimes people obtain a cute baby crocodilian for a pet, and when it grows too large, they release it into the wild where it can become a danger to other animals or people. The Florida Everglades has a problem with Burmese pythons, which people released when they became too large for pets.

We have a great responsibility for control of the animals that God has given us to oversee. God said, “Have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moves upon the face of the earth” (Genesis 1:28). That doesn’t mean to destroy them. It means to take care of them and work to produce proper management of their lives. The selfishness and greed of humans harm the planet on several levels, including puppy mills and the neglect of animals in our control. The care and maintenance of pets is an area where we need to do better.

Learn from Trilobite Eyes

Learn from Trilobite EyesOne of the more interesting fossils you will ever find is a trilobite. This three-lobed ocean-going creature was an arthropod related to insects and crabs. Its closest living relative is probably the horseshoe crab, although behaviorally, it may have been more like a lobster or crayfish. Today we find beautifully preserved trilobite specimens in rocks dating back to the beginning of life on Earth. What can we learn from trilobite eyes?

We can study and learn from trilobite eyes because they were made of the mineral calcite. Calcite is the same mineral that makes up limestone, so it is quite hard and efficiently preserved. In its purest form, it is perfectly clear. Calcite possesses what scientists call a double index of refraction. Because of the arrangement of atoms in calcite, light arriving at one angle passes undisturbed while light at another angle will be split into two beams.

In addition to being made of calcite, the trilobite eye was made up of a honeycomb of hexagons. There could be several thousand hexagons in the eye arranged so that light from any angle would be refracted into the animal’s eye. If it came perpendicularly, the light would go straight to the back of the eye. If it came at an angle, the double index of refraction would still bring the light to the back of the eye. There was a small wall between the hexagons so that light from the hexagons did not overlap each other. When arthropods grow, they molt their outside layer, and the new larger layer hardens. The eye material would add hexagons as the animal got larger.

This kind of eye is similar to the eye of a housefly. Like flies, trilobites would have been especially good at detecting motion. They also would not have a problem with near-sightedness or far-sightedness. Something an inch away or a mile away would both be in focus at the same time.

There is one vision problem the trilobite would have. It’s called spherical aberration. The thickness of the materials in each hexagonal lens would not be the same, and that difference could distort the image. In the trilobite eye, this problem was solved by magnesium atoms added to the calcite in a way that corrects the aberration. Modern opticians do this with what they call a doublet lens.

Scientists have observed other special features in various species of trilobites. They have found some eyeless trilobites that probably lived in areas with no light, such as very deep in the ocean. Other eyes were mounted in ball-like structures that could move. Still others were positioned so that the animals could bury themselves in the sand like a stingray while their eyes could still look out for food or enemies.

There are many lessons we can learn from trilobite eyes. The incredible complexity is a tribute to God’s wisdom and design. In this case, the complexity is of particular interest because trilobites were some of the first animals to live on this planet. That fact presents a problem for those who say complexity is a result of evolutionary forces over a very long time. Trilobites already had a sophisticated visual system when they first appeared in the fossil record in the Cambrian period 500 million years ago. Darwinistic models cannot explain the trilobite eye, but the God of the Bible can.

Why Do We Have Mosquitoes?

Why Do We Have Mosquitoes?Every summer and early fall, the newspapers start talking about how horrible mosquitoes are. Then I have to deal with questions of why mosquitoes exist. If there is a kind and loving God, why do we have to worry about the diseases that mosquitoes carry? I have heard some people give rather foolish answers to this question, and I don’t wish to over-simplify in discussing it. But why do we have mosquitoes?

Many years ago, one of my professors at Notre Dame was Dr. George B. Craig, whose specialty was mosquitoes. He was “an internationally recognized expert on the biology and control of mosquitoes” according to a publication of the National Academies of Sciences. As one of his students, I learned some fantastic things about mosquitoes. Mosquitoes are pollinating insects. Most species of mosquitoes pollinate plants and don’t “bite” anything.

The word “mosquito” is Spanish for “little fly” and there are some 3500 species of them. The larvae of the mosquito are a significant part of the diet of fish and other water creatures. The mutation which turned some of them into bloodsuckers seems to have come into existence in recent history. It appears they were not created that way, and certainly have not always carried malaria and other diseases. The fact that there were no mosquitoes in Hawaii until the white man came to the islands with water barrels containing mosquito larvae is another important point to consider. The question of “why do we have mosquitoes” won’t always get answered to everyone’s satisfaction, but at least we can raise some points to make people think.

The design of the various food chains on Earth is very complex. This is especially true in freshwater areas with unique problems. In Alaska, for example, the necessary minerals for plants and the food sources for bears come from the salmon runs that bring the nutrients. The soil is sparse and nutrient-poor, and much of the year, the cold prevents normal food chains from functioning. Insects provide a significant means of moving nutrients through the system, so they are the base of the food chain in those freshwater systems. Without mosquito larvae to feed the freshwater creatures, including the salmon, that life would not exist.

Research has not given us enough data to understand how mutations in insects allow them to become disease carriers. There are multiple possible answers to that question, and future discoveries will make it more clear. Those of us who live in the north may not like the mosquitoes that make our outside activities uncomfortable, but we know how to cope with them. Why do we have mosquitoes? As we tie our dry flies to fish for trout and salmon, we see why the beauty of the north is at least partially rooted in things that complicate our lives. Mosquitoes are among those complications.

Moon Record in the Solar System

Moon Record in the Solar SystemThe solar system record for the largest number of moons has just been taken over by Saturn. Previously Jupiter was the record holder with 79. Now the moon record in the solar system goes to Saturn with 82!

Astronomers used some of the world’s largest telescopes, including the Subaru Telescope in Hawaii to make the recent discoveries. The same team led by Scott Sheppard of the Carnegie Institution for Science in Washington, D.C., discovered 12 previously unknown moons around Jupiter last year. Now they have helped Saturn pull ahead of the competition.

Here we are living on a planet with only one Moon. Should we feel disadvantaged? Not at all! Imagine how confusing it would be to live on a planet with 82 moons. Seriously, one is enough. That is especially true when we have one Moon that is just right. We have pointed out before how precisely well-designed and well-placed our lone Moon is. Here are a few reminders with links to get more information:

Our Moon…
…has just the right mass to stabilize Earth’s rotational tilt.
…is just the right distance from Earth to create beneficial ocean tides.
…is just the right size to create total solar eclipses, which have helped us to learn more about the Sun.
…works with the Sun and stars to “mark seasons and days and years” (Genesis 1:14)
…reflects the light of the Sun to give a night light essential for many forms of life.

Those are a few of the reasons our Moon is the best one in the whole solar system! We asked before, “How many moons are enough?” Even though the number of known moons orbiting Jupiter and Saturn has changed since we asked that question, the answer is still the same. One Moon, precisely designed and positioned, is exactly what we need. We hold the moon record in the solar system for the best Moon of all! There are too many “coincidences” for it to be an accident. We see the work of a Creator, who is an amazing Engineer.

Dinosaurs and the Bible

Dinosaurs and the BibleThe largest and best-funded apologetics organization in the world today is the Institute for Creation Research. They are strongly supported by fundamentalist Christian groups that have dispensational theologies. While they promote several denominational doctrines that aren’t supported by the Bible, and some of their science is not accurate, they do have a great deal of useful scientific data that supports the existence of God. However, they ran into a problem concerning “dinosaurs and the Bible.”

The most fundamental problem with the position of ICR is stated in these words from the November 2019 issue of their magazine Acts and Facts (page 4):

“Instead of attempting to harmonize the inerrant Word of God with a flimsy scientific model, Christians would do far better to simply take God’s Word at face value.”

The fact is that not all science is flimsy. Also, taking the Bible at face value when “face value” means a questionable interpretation of an inferior English translation. We have often dealt with dinosaurs and the Bible before. You can find some of our previous posts HERE and HERE.

There is no question but that those of us who believe in God and the Bible as His Word share common problems. In that same issue of Acts and Facts, Jayme Durant, the editor of the magazine, tells of trying to put up billboards in the Dallas area. They wanted to advertise the Discovery Center, a new multi-million dollar museum they have opened in the Dallas area. The billboards had their logo with the simple message “Dinosaurs and the Bible?” Two of the billboard companies would not allow ICR to display their message as long as they used the words “Bible” and “Dinosaur” together.

Here is the complete message of the sign owners:

“It’s controversial to have a statement that may challenge local beliefs. Saying ‘Dinosaurs and the Bible?’ may stir the pot in that area and cause problems for the sign in that area.”

Durant points out that “…making people think about something that might be outside their paradigm is apparently unacceptable by much of the American public.” Our society continues to show its bias and antagonism toward God and the Bible. Durant concludes her essay by writing, “You might be accused of stirring the pot. But that’s okay–your life is your billboard. And every day, you can choose the message you display.” We may not agree with ICR on dinosaurs and the Bible, but we certainly agree on that.

Strong Man to Run a Race

The Sun Is Strong Man to Run a Race“The heavens declare the glory of God; and the expanse shows his handiwork … Their measuring line goes out through all the earth, and their words to the end of the world. In them has he set a tabernacle for the sun which is like a bridegroom coming out of his chamber and rejoices as a strong man to run a race.” Psalms 19:1, 4-5.

The choice of Hebrew words in this psalm is impressive, and modern science has enabled us to understand why the writer compares the Sun to a strong man. The Sun has about seven billion years’ worth of fuel. That is enough to make 31 orbits of the milky way taking about 225 million years to complete each orbit. The Hebrew word for “run” used here is “ruwts,” which means “to run swiftly.” The word “race” is translated from the Hebrew word “orach,” which means “a pathway or highway.

Modern measurements show that the Sun is moving at 520,000 miles per hour (836,859 kph) around the galaxy, and the galaxy itself is moving at 1.3 million miles per hour (2,092,147 kph) through space. Not only can we marvel at the size and speed of our solar system but also at the choice of words used in the Bible to describe the creation itself. We can poetically and accurately compare our Sun to a strong man to run a race.

Deserts, Oceans, and Life

Deserts, Oceans, and LifeHave you ever been in a desert for an extended time? Have you ever taken the sand of a desert and looked at it under a microscope? Have you visited the Great Salt Lake or the Dead Sea? Do you feel that deserts are a wasteland? Science has come to understand something about deserts, oceans, and life that shows wisdom and planning that is beyond our wildest dreams.

We now know that deserts, in general, are dried up lakes. The vast Death Valley desert in the United States (pictured) was a lake at one time. So was the Atacama Desert in Chile, which is now called “the driest place on Earth.” The African Sahara was once the largest lake on Earth called the Mega Chad. Fossil hunting in these deserts reveals the remains of fish and plankton called diatomite. Diatomite is the skeletal remains of microscopic forms of life called diatoms. The skeletons are composed of silicon dioxide, which is a very durable substance and is highly porous and lightweight. These factors make it ideal for the wind to carry. Diatomite also contains phosphorous, which is essential for life to exist. Every living cell needs water and phosphorous, which is the second most abundant mineral in our bodies.

To have rain on the Earth requires water vapor, cool temperatures, and condensation nuclei on which the water can condense. When bodies of water become deserts, the dust contains phosphorus. Wind currents of our planet take the dust from deserts which once were lakes and carry it vast distances. Dust particles become the nuclei for condensation of raindrops that carry water and nutrients to the ground. The deserts of the Sahara maintain life in the Amazon basin. Lightning in the storms produces nitrogen to add to the nutrients. This pattern is repeated in every life-filled system on Earth. The Great Plains of the United States are sustained by the dust and minerals of the Mojave Desert, an old inland sea.

The Bible refers to all of this in passages like Isaiah 50:2 and Job 38:37-38. It is not the purpose of these passages to reveal the complex system that produces the water and nutrients for life to exist. However, the references to the dust and the drying of the sea make it clear that the ultimate Author of the scriptures knew the processes used to supply a planet uniquely designed to harbor life. Deserts, oceans, and life speak to the design built into the Earth. They also show us that God has given us what we need for life and the scriptures to provide a reliable guide for living.

Why We Need Lightning

Why We Need LightningAll life forms on planet Earth need nitrates to build proteins and DNA. We get our nitrates from the plants and seeds that we eat. Plants absorb nitrates from the soil through their roots. The nitrates in the soil come from rain that has absorbed nitrates from the air through which it falls. The nitrates in the air come from the action of lightning. Our atmosphere is 78% nitrogen, and lightning takes some of the nitrogen and catalyzes it into a bond with oxygen to make nitrates. That is why we need lightning.

A surprising thing about this complex system is that the lightning is far more abundant than we realize. Lightning strikes the Earth around 1000 times every second. Above the clouds, in the upper atmosphere, there are continuous lightning types that we don’t see from Earth’s surface. They are called elves, sprites, blue jets, and gigantic jets, depending on their color and shape. There is a voltage difference between the ground and the ionosphere, which varies from 200,000 volts to 500,000 volts. Even in fair weather, there is a constant flow of current, which scientists believe is caused by the spinning of Earth’s core. All of this adds up to a total of over three million lightning strikes a day, and each produces nitrates to sustain life. The jet stream carries these nitrates around the planet, providing a natural fertilizer in places where electrical storms rarely occur.

The Old Testament contains suggestions of this being a part of God’s design for life on Earth. Ecclesiastes 1:6 talks about wind patterns, and Jeremiah 10:13 speaks about lightning. Job 36:29 and 37:21 speak of clouds and bright lights. Lightning is sometimes destructive, often because of foolish construction by humans or ecological problems caused by human mismanagement. In reality, lightning is a tool God uses to build and maintain life on Earth. That is why we need lightning. The more we learn of the creation, the closer we get to the Creator.
