December Solstice and What It Means

After today, Sunday, December 22, 2019, the hours of daylight will begin to be longer in the Northern Hemisphere where we live. Last night at 11:19 p.m. local time (Eastern Standard), the December solstice occurred as the Sun reached its lowest point in the dome of the sky, even though we couldn’t see it. It happened at the same moment all over the Earth, but, of course, local times varied. (It was at 04:19 Universal Time, and you can figure your local time from that.)

The December solstice ushers in winter in the Northern Hemisphere and summer in the Southern Hemisphere. So for those of us in the north, the days will now start to slowly get longer as the weather gets colder. South of the equator, the situation is just the opposite. At the North Pole, there are 24 hours of darkness when the Sun never appears. At the South Pole, the Sun is up for 24 hours.

Although the December solstice is the time when the Sun is at its farthest point south, it hasn’t moved. We have. Earth’s axis is tilted 23.5 degrees from the path of its orbit path around the Sun. Each year that tilt causes us Earthlings to perceive that the Sun is moving north or south. Earth’s orbit is somewhat elliptical rather than a perfect circle. The point when Earth is closest to the Sun occurs in January during the Northern Hemisphere’s mid-winter. It’s mid-summer in the Southern Hemisphere, so you might think that their summers would be extra hot. Whatever increased heat would occur because of the proximity of the Sun is counteracted by the fact that the Southern Hemisphere is mostly covered by oceans which absorb the heat. That is just another part of our amazingly well-engineered planet.

In Genesis 1:14, we read that God said, “Let there be lights in the expanse of the sky to separate the day from the night, and let them serve as signs to mark seasons and days and years.” Ever since Adam and Eve, people have recognized the Sun’s regular path across the sky and the changes in daylight, sunrise, and sunset times throughout the year. In ancient times, they didn’t understand why. We know why and we marvel at the design.

Every creature on Earth is affected in some way by the length of daylight. Historically, people in the Northern Hemisphere have celebrated the December solstice because it means the days will start getting longer, and spring will return. In ancient Rome, the people called their celebration Saturnalia and honored their pagan god Saturn with immoral behavior. With the coming of Christianity, the Christians re-purposed the holiday to honor the coming of Christ into the world. While the pagans celebrated with debauchery, the Christians made it a time of praising God and the gift of His Son. Jesus was almost certainly not born at this time of year, but more likely in the spring. However, we should take time to honor God for the beautiful design of our planet that makes life possible, and the wonderful gift of Jesus that makes eternal life possible.

Earth’s Twilight and What It Means

The part of Earth’s atmosphere we live in, fly airplanes in, and which contains over 90% of our oxygen is called the troposphere. It is much thinner than you may realize. Earth’s diameter is about 8,000 miles, and the thickness of the troposphere is much less than eight miles, making it one one-thousandth of the diameter of Earth. Our air is like an onion skin around our planet. Earth’s twilight daily reminds of the thin blanket that protects us.

You might wonder if the thin nature of our atmosphere is not a risk to us. The truth is that our troposphere is a uniquely designed structure, and if it were any different, life could not exist on this planet. The troposphere has to be…

…thin enough to allow enough light in for the photosynthetic processes of plants, but thick enough to burn up hunks of rock from space as they are pulled in by Earth’s gravity.

…thick enough to provide oxygen to breathe, but not so thick as to create pressures that would cause oxygen toxemia.

…thick enough to trap enough of the Sun’s heat to keep us warm, but thin enough to not overheat us.

…thick enough to refract and scatter dangerous radiation away from us, but thin enough to allow critical wavelengths to reach Earth’s surface for biological purposes.

…thick enough to allow water to exist as a liquid, but not so thick that other gases liquefy or dissolve in water,

These are just a sampling of the critical elements involved in the design of the troposphere. There are additional layers above the troposphere that do other things to support life on this planet. As science has examined the atmospheres of other planets within our solar system, we see that they are very different. The acid air and greenhouse effect of the atmosphere of Venus has turned it into a hellish environment. We do not have the ultraviolet light that bathes and sterilizes Mars because our ozone layer filters out much of that destructive component of the Sun’s light.

Each day as we watch Earth’s twilight come, we should be reminded of the incredible wisdom built into the structure of our atmosphere. As the sky turns from blue to a brief green, to yellow, to orange, and then red, we are seeing the longer wavelengths which we don’t see in the daylight because they are mixed in our atmosphere. Our air keeps X -rays away from our planet. Its density allows flight and keeps the lakes and oceans from evaporating. Its low density allows it to move and carry warmth and moisture from one area of our planet to another so that life can exist from the equator to the poles. Earth’s twilight is a daily reminder of the care and design built into our planet because of God’s love and wisdom.

Do Exoplanets Disprove God?

One of the interesting developments of the past twenty years has been the study of planets orbiting stars other than our Sun. So far, scientists have discovered more than 4,000 exoplanets. Those who believe the formation of Earth and its ecosystem is a product of blind mechanical chance seize upon this fact to affirm that God had nothing to do with the creation. They argue that given enough time and enough planets, life was bound to happen somewhere eventually. Do exoplanets disprove God?

One obvious difficulty with this claim is that the real issue of creation is how time, space, and matter/energy came into existence in the first place. How it got into a form that would sustain life is a matter of whether the creation was designed and planned by an intelligence, or whether it was a product of chance. Astronomy magazine, in its January 2020 issue, carries an article about the summer 2019 discovery of the first planet that exists in the habitable zone of its star. The media at that time made wild claims about the probable existence of life on that planet. Known as K2-18b, the planet orbits a red dwarf star which is about one third the mass of our Sun. What that means is that water could exist on the planet as a liquid.

So could life exist on K2-18b? This discovery highlights the incredible complexity of planet Earth. K2-18b is roughly twice the diameter of Earth and eight times as massive. The mass of the planet means that gravity there would be much higher than Earth’s gravity. That would result in a much deeper and denser atmosphere with pressures and temperatures thousands of times higher than we experience on Earth. Also, red dwarf stars emit powerful flares, and the orbit of K2-18b is twice as close to its star as Mercury is to the Sun. There is no way that life could survive the conditions on this planet, even if liquid water were present.

Remember that K2-18b is the first planet discovered that is located in a so-called habitable zone. The study of exoplanets has shown that the creation of planet Earth is a highly unique and special event. Do exoplanets disprove God? As we have said before, God can create life anywhere He wants to. But as more and more data becomes available on what exists throughout the cosmos, support for God as the creator and sustainer of life on this planet grows.

Stirring the Pot – The Sun and Parker Solar Probe

If you do any cooking, you know that to be a successful cook, you have to stir the pot every so often. Not only does stirring the pot prevent the food from sticking to the bottom, but it also improves the flavor by mixing the ingredients. The Earth and its relationship to life is also a kind of pot. We are just beginning to understand how complicated the relationship is between the Sun and the various ecosystems on Earth that allow life and advanced life to exist.

In 2018 NASA launched a probe called the Parker Solar Probe to fly near the Sun and make measurements and observations. No space probe has ever been close enough to the Sun to gain much data, but this probe was designed to fill that gap in our knowledge. At this point, it is about halfway between the Sun and Mercury, the closest planet to the Sun.

The Sun has what are called switchbacks when the magnetic field briefly reverses itself. This reversal varies the amount of solar wind coming to the Earth. This variable wind compresses Earth’s atmosphere, stirring the pot, so to speak. The mixing of the gases makes changes in our atmosphere, which we can observe in the auroras. The magnitude of the switchbacks also affects our power grids and orbiting communication satellites.

It is obvious that the movement of materials in our atmosphere and the constant changes that take place are part of the solar system design. The new data may open doors not only to how we can protect our power grids, but it may give us further understanding of the origin and sustaining of life on Earth.

Stirring the pot is one more factor in the intricate design of our planet and solar system that makes life possible. When Proverbs 8 talks about wisdom being present before the creation, it speaks of things we are just beginning to understand. The more we know of the creation, the more we know of the Creator.

Milk Production and Greenhouse Gases

Milk Production and Greenhouse Gases How do you feed millions of humans and meet their nutritional needs without destroying the planet with greenhouse gases? The World Wildlife Federation has released data on one of the primary sources of food for more than six billion people worldwide – milk. The average person in the United States consumed 643 pounds (292 kg) of dairy products in 2017, including milk, butter, cheese, yogurt, and ice cream. Those foods came from 9.3 million dairy cows, but there are 278 million in the world. Milk production has grown by 30% from 2005 to 2015, and that comes to 909 million tons. India is the leading producer with 20% of the world’s supply. The U.S. has 12%.

The design of cattle that can produce that much milk was recognized in prehistoric times, and cattle were worshiped because they provided so much food for humans. Skeptics would respond that the environmental impact of cattle is so huge that it is a bad design. It does take 144 gallons of water to produce one gallon of milk in the U.S., with over 93% of it involved in growing feed for the cattle. The average dairy cow will eat 100 pounds of feed, and 9% of American cropland is used to grow feed crops for dairy cows. A cow will produce 17 gallons of urine and manure, which can pollute rivers and lakes, and they generate greenhouse gases.

The fact is that only 2% of the total U.S. emission of greenhouse gases comes from milk production. The Northern Great Plains cover 180 million acres in Montana, Nebraska, North Dakota, South Dakota, Wyoming, Alberta, and Saskatchewan. The land became rich in resources and healthy when grazing animals such as bison aerated and fertilized the soil. With the past numbers of those animals gone, scientists now say that something else must fill that niche or erosion will increase, and invasive plants will take over. Studies by the World Wildlife Federation show that cattle production areas in the Northern Great Plains have lower per acre emissions than row crop agriculture such as corn, soybeans, and wheat. The most recent study shows “done right, ranching can help conserve biodiversity while minimizing its own environmental footprint.”

Like everything else that God has given us, milk production must be managed carefully and with a concern about “taking care of the garden, dressing and keeping it” (Genesis 2:15). Milk is one of God’s great blessings, and a land “flowing with milk and honey” is held out as the most favorable place to live.

James Peebles Wins Nobel Prize in Physics

James Peebles Wins Nobel Prize in Physics Those of us who have an interest in creation have followed the work of Dr. James Peebles at Princeton University for some time. Since 1964, Peebles has been working to understand the scientific evidence of how the cosmos came into being. For his work, he has won the 2019 Nobel Prize in Physics.

Dr. Peebles predicted cosmic microwave background radiation, which has been a major tool in understanding the beginning of the universe and in realizing that 95% of the matter/energy in the cosmos is unknown. The “big bang” model describing the universe fits well with understanding God’s role in the cosmos. Peebles has shown that the formation of space/time and matter/energy fits with all available observations, and he has discovered several new processes, such as the baryon model, to describe the physics of the early universe.

The Ostriker-Peebles criterion relating to the stability of galactic formation has helped us understand other galaxies besides our Milky Way. Observing the spin rates in those galaxies has led us to realize that the rapid speeds at which they move require a force that has not been identified to prevent them from flying apart. This realization is the starting point for speculating the existence of dark matter. There has to be a missing mass that is the glue of stable galaxies. Research continues to understand what dark matter is and how it works.

Dr. Frank Baxter once said, “the more we know about the creation, the closer we get to the creator.” The fact that James Peebles has been recognized for his work in cosmology is encouraging. Scientists now agree there was a beginning. The cause of that beginning and the properties of that cause are the next steps toward comprehending the creation of the cosmos.

Proverbs 8:22 finds wisdom saying, “The Lord possessed me in the beginning of His way, before His works of old.” Reading Dr. Peebles’ research is intimidating because God’s wisdom and His works in cosmology are so complex. The study of creation in cosmology has only become recognized as valid science in the last few years. James Peebles has been a major player in accomplishing that, and therefore he received the Nobel Prize in Physics. “In the beginning, God created” may sound simple, but what it describes is incredibly challenging to understand. Dr. Peebles has clearly shown that, but he has also opened the door for more study of how God did the creating.

Rossby Waves and Earth’s Climate

We have previously discussed the movement of air around the Earth, and the circulation pattern called the Hadley cells. Another important factor in Earth’s climate is Rossby waves.

Because the equator is hot, heated air rises and moves away from the equator, dropping its moisture as it cools. At about 30 degrees latitude, the now dry air falls back to the Earth, producing deserts. As the air reaches Earth’s surface, it moves north and south, creating the trade winds in the subtropical area and the prevailing mid-latitude winds in latitudes between 30 degrees and the polar regions.

A wide range of things alters this simplified picture. When greenhouse gases like carbon dioxide accumulate, they reflect infrared radiation causing the Earth’s atmosphere to become hotter. This effect isn’t uniform, however. Because of melting sea ice, Earth’s poles are affected by greenhouse gases more than the area of the equator. This causes a thermal imbalance between the poles and the equator affecting circulation around the poles and creating Rossby waves.

As the thermal imbalance has become greater and the air more wobbly in recent years, that affects the jet stream. The wobbles this past year have caused the northern jet stream to go further south than usual, bringing cold into Arizona in late spring. When the jet stream swung north, it brought hot tropical air toward the poles. On its way north, it brought unusual amounts of water into Oklahoma while Anchorage, Alaska, got temperatures over 90 degrees for the first time ever. Rossby waves is the name applied to the meandering high-altitude winds that have a major influence on Earth’s weather.

All of this shows us how fragile Earth’s climate is. Weather patterns depend on a wide range of variables which include the:
*size of the Earth’s atmosphere
*tilt of the Earth
*distribution of land compared to water
*chemical makeup of the atmosphere
*kind of radiation coming from the Sun and how that radiation is absorbed and reflected
*nature of Earth’s surface (whether ice or black dirt)
All of those factors go into making Earth a habitable planet.

We exist on this planet because of the precision design and construction of Earth and its atmosphere. The fact that it has stayed stable long enough for human life to exist for thousands and thousands of years is a testimony to the careful design and construction. Proverbs 8 finds “wisdom” speaking about its role in the creation process. Wisdom says she was there before the creation (verse 22-23) and that wisdom was a part of the preparation of the heavens (verse 26-28).

As we see the results of the small changes that have happened to the atmosphere in the past 100 years and the instability of Rossby waves, we wonder at Earth’s design and the wisdom of God who created it.

What the Mercury Transit Tells Us

What the Mercury Transit Tells Us Above is a photo of the Sun. If you look closely, you will see a small dot in the upper half near the right side. That is the planet Mercury, the closest planet to our Sun. Mercury made what astronomers call a “transit” of the Sun on Monday morning, November 11, 2019. In our area of the country, the sky was overcast, and it was snowing. However, Bill Ingalls of NASA took this photograph from his location in Arlington, Virginia. I find it interesting to consider what the Mercury Transit tells us.

What’s so special about Mercury passing in front of the Sun? For one thing, it doesn’t happen very often. Although the last time was only three years ago, the next time will be in 2032, but it won’t be visible from North America. The next Mercury transit visible in North America will be in 2049. Since Mercury is closer to the Sun, it passes between the Sun and us every 116 days. However, most of the time, it is either above or below the Sun from our view, and Earth’s atmosphere makes it invisible in the daylight.

Scientists used precision telescopes and equipment to study the transit. They can learn more about the atmosphere of Mercury as it is silhouetted against the Sun. Historically Sir Edmund Halley (1656-1742) watched a transit of Mercury and realized that it could be used to measure the distance between the Earth and the Sun. It occurred to him that a transiting planet would appear in different positions to viewers in different locations on Earth. Measuring the apparent shift between two distant Earth locations at the same time and applying a little math, one could calculate the distance to the Sun. In 1769, after Halley’s death, astronomers used a transit of Venus to calculate the Earth-Sun distance.

Think about what the Mercury transit tells us without even seeing it? Because of the fact that astronomers can know in advance the exact date and time of a transit of Mercury (or Venus), or a solar eclipse (when the Moon passes between Earth and Sun) we realize that the solar system is orderly. We can study the heavens and learn of the Creator. We can see His wisdom and design of our planet and the solar system in which it exists. We can know there is a God by the things He has made (Romans 1:20) as the heavens declare His glory (Psalms 19:1).

Space Debris: A Growing Concern

Space Debris: A Growing Concern to Astronauts in Space A 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

I 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.
