Let There Be Light

Let There Be Light - X-rays from the Whirlpool Galaxy



The Whirlpool Galaxy M51 and companion M51B. The green glow at the center of each is X-ray radiation from black holes.

The third verse of the first book in the Bible quotes God, saying, “Let there be light.” Most people don’t understand the full meaning and impact of that statement. For the past two days, we have examined how the ability to see invisible light revolutionized astronomy. First, we looked at the forms of light at frequencies below the visible spectrum. Today, let’s look at frequencies above the light we can see.

Higher frequencies mean shorter wavelengths, and electromagnetic energy above the frequency of visible light has wavelengths short enough to penetrate living cells and damage them.

Ultraviolet is the first band of light above the visible spectrum. The Hubble Space Telescope is the leader in observing ultraviolet light coming from the hot and energetic formation of young stars. Auroras on gaseous planets like Jupiter also emit ultraviolet light. The ability to see the invisible UV light helps us understand more of the process God used in creation.

Our Sun is also a source of ultraviolet light, and everyone knows UV light can cause painful sunburns. Because of its short wavelength, UV light can penetrate and damage cells resulting in skin cancer. God has given Earth an upper atmosphere ozone layer that absorbs much of the ultraviolet radiation. While protecting us from health damage, the atmosphere makes ultraviolet astronomy impossible on Earth. That’s why the Hubble Space Telescope leads in UV observation of the universe.

Above ultraviolet light, we find X-rays that are even more harmful to living cells. This band of invisible light energy can penetrate matter. Because of that, they are useful in medicine for doctors to see inside your body. However, medical X-rays must be limited because they can cause DNA mutations leading to cancer.

In astronomy, X-rays allow astronomers to study some of the hottest places in the universe, such as supermassive black holes and neutron stars. Thankfully, God has placed us far from black holes and neutron stars. However, our Sun also produces X-rays, but Earth’s atmosphere blocks X-rays. Therefore, X-ray telescopes, such as NASA’s NuSTAR mission, must be located in space.

Finally, let there be light at the top of the invisible spectrum. Astronomers use the shortest wavelength, gamma rays, to study the creation. Unfortunately, gamma rays have the highest energy and are the most dangerous to living cells. Supernova explosions release gamma rays, and space telescopes such as NASA’s Fermi and Swift can detect them. Fortunately, those gamma-ray-producing events are far from Earth. However, nuclear explosions on Earth also produce gamma rays, and the Sun occasionally produces gamma-ray flashes in solar flares.

By studying all of these forms of light, astronomers today know much more about the universe and the processes God has used to create and sustain it. As we look into the night sky, we are looking back in time and seeing the various frequencies of electromagnetic energy. It is light, both visible and invisible, and it tells us of the power and wisdom of the process that brought our planet and the life upon it into existence. Light is energy, and energy is matter (e=mc2). Knowing that, we realize what a profound statement Genesis 1:3 contains – “Let there be light.”

Eight Billion People on Earth

Eight Billion People on Earth

In November of 2022, the human population hit eight billion people. That means eight billion people need food, shelter, and energy for transportation and protection from the elements. In Genesis 1:28 and 9:1, God told Adam and Eve and later Noah and his family to “be fruitful and multiply.” Then the text uses the Hebrew word “mala” the Earth. Mala can mean fill, replenish, satisfy, accomplish, or confirm, according to Strong’s Exhaustive Concordance.

God’s command to early humans told them to take on the responsibility of caring for the planet. It does not mean their only purpose would be to have lots of children. God expects us to control and care for the creation, not merely endure its challenges. There is a fundamental difference between the biblical concept of our relationship to the planet and our present state, which has caused poverty and starvation.

The Christian system teaches a one-man/one-woman system of marriage as opposed to polygamy. It also teaches that being a father places responsibilities upon men. Passages like Ephesians 6:4 and Colossians 3:21 make it clear that fathering children gives men a responsibility to encourage and guide them.

The quality of life for Earth’s eight billion people depends on how we manage the issues of population control and caring for the environment. The teachings of Christ support the nurturing of the Christian family. The selfish and reckless placing of pleasure above all else brings pain to the individuals who embrace it and tragedy to human society. Promoting and following the Christian system of values is essential for human flourishing, and the collateral damage produced by not following it is becoming increasingly evident.

Use of Cannabis by Seniors

Use of Cannabis by Seniors

The use of marijuana to treat chronic pain and discomfort like arthritis has been widely publicized and legalized in many states. So naturally, those of us who are older look for any way to relieve the aches and pains that come with age. Because of that, the use of cannabis by seniors has increased dramatically.

Certainly, we should use anything God has given us to relieve human discomfort as long as it is not harmful. We must understand that one of God’s injunctions is to take care of the body, which the Bible says is the dwelling place of God’s Spirit (1 Corinthians 3:16).

We are responsible for ensuring that what we use to relieve discomfort is good for us and doesn’t harm our bodies. That means we must use caution and listen to research about so-called miracle cures. But unfortunately, new studies of the use of cannabis by seniors have raised a red flag about its safety.

The Journal of the American Geriatrics Society for January 9 reports on visits to emergency departments in California, where marijuana has been legal for any use for several years. Cannabis-related visits to emergency rooms by seniors (ages 65 and older) rose from 366 in 2005 to 12,167 in 2019.

Unfortunately, there is big money in the marijuana business, so cannabis merchants are promoting its use. However, you should use it under a doctor’s supervision. It should not be a matter of simply going to your local marijuana store and accepting all the claims they make for a “miracle cure” for whatever ails us.

How to Deal with Death

How to Deal with Death

One of the most significant challenges of our time is how to deal with death, and as medical science advances, the issue becomes more critical. Some project that by the year 2050, the U.S. government will spend a trillion dollars a year on millions of institutionalized Americans with Alzheimer’s and advanced stages of dementia. That is 50% more than all federal, state, and local agencies spend today on K-2 public education.

On a more personal level, Americans often spend the largest amount on medical care during the last year of life, depleting family resources and frequently leaving surviving family members destitute. I personally know of widows in our area who are living on a day-to-day basis because they spent all their savings caring for a dying husband. 

Medically assisted suicide is the current trend in how to deal with death. Ending one’s life at a time and in a place of their choosing is now legal in Australia, Austria, Belgium, Canada, Colombia, Luxembourg, the Netherlands, New Zealand, Spain, and Switzerland, where it has been legal since 1942. Organizations worldwide and in the United States assist people in arranging legal medically assisted suicide.

At the moment, there are ten states and the District of Columbia that have medically assisted right-to-die programs. This trend began on November 22, 1998, when 60 Minutes broadcast a video of Michigan physician Jack Kevorkian administering voluntary euthanasia to Thomas Youk, a 52-year-old man with advanced Lou Gehrig’s disease. Oregon passed the nation’s first “death with dignity” law four years later, and other states followed after 2016. 

In Canada, a person can end life as young as 18 and need not have any life-threatening illness. In 2021 over 10,000 Canadians ended their lives through state-approved euthanasia. This statistic highlights a significant “slippery slope” problem with euthanasia or assisted suicide laws. They can expand to include people who have minor mental or social struggles. 

St. Thomas Aquinas wrote, “It is altogether unlawful to kill oneself because life is God’s gift to man and subject to His power, Who kills and makes to live. Hence whoever takes his own life sins against God.” In 1 Corinthians 3:16-17, Paul wrote, “Do you not know that you are the temple of God and that the Spirit of God dwells in you? If anyone defiles the temple of God, God will destroy him. For the temple of God is holy, which temple you are.” There is no easy answer to this question of how to deal with death. However, many of us will face the hard choices the end of life can bring.

How the Elements Were Crafted

How the Elements Were Crafted - Supernova 1987a
Supernova 1987a

One of the great mysteries of science has been the question of how the heavier elements came into existence. Physicists have produced a few heavy elements in particle accelerators, and they have observed them being made in stars. Understanding how the elements were crafted is a solid apologetic for God’s creative power and wisdom. Being able to duplicate in a laboratory what God has done in the vast outreaches of space increases our amazement at what God has done.

As we said yesterday, the ability to produce nuclear fusion may solve our energy needs, but the fact that God did it “in the beginning” has led to a greater appreciation of God’s power and His methods. We know that the nuclear fusion of hydrogen can produce helium. We can duplicate that process in the laboratory on a small scale and see it in operation in the Sun.

Hydrogen (1) was produced first, but forging elements, including carbon (6), nitrogen (7), and oxygen (8), required enormously high pressures and temperatures in the interior of stars. These elements are the four starting points for life—still heavier elements require even greater pressures and temperatures.

In 1987, astronomers watched a star explode, becoming supernova 1987a. After the explosion, astronomers detected neon (10) in the star, which was not there before. Direct and indirect observations of the nuclei of exploding stars has shown how the elements were crafted as God produced the following 28 elements in the periodic table. This group includes copper and phosphorus, which are present in our bodies and are essential to life.

As our cosmic tools have become capable of detecting gravitational waves, we have seen even heavier elements produced when neutron stars collide. For example, computer models have shown that those collisions can produce the elements gallium (31) through bismuth (83). In addition, the merger of two black holes can produce very heavy elements such as thorium (90) and uranium (92). The bottom line is that we can see how the elements were crafted by God. He made the universe and our bodies from elements produced in the core of ancient stars.

Obviously, the Bible doesn’t explain how the elements were crafted. However, it does tell us that God acted “in the beginning” to set the process in motion. As we observe the universe through new tools such as the Webb Telescope with the help of computers, we can see a vivid display of God’s power and wisdom in creating all that we see and are. For most of us, “In the beginning, God created” is all we need to know, but as science learns what it takes to create the building blocks of creation, we have a whole new appreciation of “the heavens declare the glory of God and the expanse proclaims the work of his hands” (Psalms 19:1 CSB).

Nuclear Fusion to Power the Future

Nuclear Fusion to Power the Future

People today are concerned about “green energy.” The government is attempting to move the economy away from fossil fuels to protect the environment and reduce climate change. However, all of the alternative power sources have limitations. What we need is nuclear fusion to power the future.

Presently, the favored alternatives to fossil fuels are wind and solar, both of which have drawbacks. They include the expense of installing and maintaining them, plus the fact that sunshine and wind are only sometimes available. In addition, there are few locations where water power is feasible, and building dams on rivers can cause other issues. Nuclear fission is probably the most efficient method of generating electric power without putting carbon in the atmosphere. However, past catastrophes cause people to fear that option. Plus, nuclear fission creates waste that will be radioactive for years, and we have no place to store it.

On the other hand, nuclear fusion can release massive amounts of power. After all, that’s what powers the Sun and other stars. With nuclear fusion, there is no radioactive waste and no carbon to create greenhouse gases. The byproduct produced is helium, a useful resource in short supply.

Nuclear fusion to power the future sounds like the answer to all of our problems, so why aren’t we switching to it now? The problem is that science hasn’t found a practical way to do it. However, in December 2022, scientists at the Lawrence Livermore National Laboratory in California produced nuclear fusion in a lab. The tiny reaction was nowhere near what the Sun does, and it lasted only trillionths of a second. But it was a start. Thirty private fusion companies worldwide are using the Livermore breakthrough as a pattern to promise clean energy that would outpace wind or solar, or anything else we now have. The Fusion Industry Association suggests they could generate fusion electricity sometime in the 2030s.

Is nuclear fusion to power the future just a pipe dream, or could it really happen? God has given us everything we need for an advanced civilization. Intelligent planning of Earth’s history provided the fossil fuels needed to bring us into the modern age. Einstein’s equation e=mc2 revealed the enormous power contained within each atom. By releasing some of that power, we have generated electricity by nuclear fission. By applying the intelligence God gave us, we can go a step further and release even more power through nuclear fusion. That could get us away from depending on energy sources that are unreliable or pollute the atmosphere.

The truth is that tiny atoms are held together by incredible power, and releasing that power can solve our energy needs. The power that holds every atom together had to have a source—the One who created everything and holds everything together. “[Jesus Christ] is the image of the invisible God, the firstborn of all creation. For by him all things were created, in heaven and on earth, visible and invisible… And he is before all things, and in him all things hold together” (Colossians 1:16-17 ESV).

Waste of Food and Resources

Waste of Food and Resources

One of the great tragedies of American culture today is the incredible waste of food and resources. People in many places around the world are surviving on less than 1000 calories per day, and starvation is killing vast numbers. Over a third of the food produced in the United States is never eaten. On average, Americans throw away a pound of food per person daily. The Environmental Protection Agency says the water and energy wasted in the United States in a year would supply more than 50 million homes.

The problem is not just the waste of food and resources but also how we use the land to produce food. The University of Oxford and Global Change Data Lab tell us that 50% of the world’s habitable land and 70% of freshwater goes to growing food and raising livestock. So when we throw away food, we also waste land and water resources. Three-fourths of the global ocean and freshwater pollution comes from agriculture. Greenhouse gas emissions from one year of food waste in the United States alone are equivalent to the emissions from 42 coal-fired power plants. 

God has provided us with all the resources we need to feed the world’s population, but corporate greed, selfishness, ignorance, and a lack of concern for others cause the problem of world hunger. In Matthew 25:31-46, Jesus described judgment based on how we conduct ourselves in meeting the needs of others. The first thing Jesus mentions is that providing food for others is a responsibility of His followers (verses 35 and 42). One way we can do that is by avoiding the waste of food and resources God has given us and becoming leaders in the war against hunger. By living in obedience to Christ, we witness the reality of God to the world.

Meeting Human Needs

Meeting Human Needs or Loving Money

Yesterday the mail brought an appeal from the 100th organization asking us for money for a cause somewhere in the world. Some are organizations dealing with politics, and others are trying to protect animal life or solve environmental issues. Seventy-four were organizations meeting human needs, including blindness, disease, poverty, birth defects, mental illness, and victims of war. Many organizations meeting human needs have budgets well under a million dollars. They get their money from people like me, who are not wealthy but give what we can. Yet, because there are so many of us, these organizations continue to accomplish their work.

A news item that arrived yesterday was a list of the dollar value of contracts between major league baseball players and their teams. Aaron Judge topped the list with a 360 million-dollar contract. The total for the top three players reached a billion dollars. The top fifteen major league baseball players signed for over sixty million dollars each. We could find similar data for NFL football players or NBA basketball players. The wealth of politicians, the amount paid to movie stars, and the salaries of CEOs in the business world are staggering for those of us who get by on less annual income than some of these people make in an hour.

So how much do the world’s wealthiest people give to organizations meeting human needs? Of course, there are a few cases where the rich support good causes. But considering the lifestyles of most of the rich, we understand why Jesus told His followers, “Truly I tell you, it will be hard for a rich person to enter the kingdom of heaven. Again I tell you, it is easier for a camel to go through the eye of a needle than for a rich person to enter the kingdom of God” (Matthew 19:23-24 CSB).

The Bible tells about rich people who made a positive difference, but overall the message is that the love of money crowds out everything else. “But those who want to be rich fall into temptation, a trap, and many foolish and harmful desires, which plunge people into ruin and destruction. For the love of money is a root of all kinds of evil, and by craving it, some have wandered away from the faith and pierced themselves with many griefs” (1 Timothy 6:9-10 CSB).

The track record of the very rich is not good. Suicide, alcohol and drug addiction, broken marriages, lost children, and the lack of genuine companionship abound. Meanwhile, the flow of misery from undeveloped countries is accelerating, and the followers of Christ are shipping the food, drilling the water wells, and providing medical help to meet human needs. Our thanks to all who follow the teachings of Jesus and give sacrificially to meet the needs of others.

Tool Use Discoveries in Anthropology

Tool Use Discoveries in Anthropology - Long-tailed Macaque
Long-tailed Macaque in Thailand

Scientific articles about tool use as an indicator of pre-human activity in the distant past may have to be rewritten. New discoveries show that the “tools” some anthropologists claimed were used by ancient hominids may be stone flakes accidentally created by monkeys.

Researchers have observed long-tailed macaques in Thailand using rocks to pound open palm nuts. When they use rocks containing flint or quartz, they create flakes or shards. Those fragments are very similar to some sharp-edge stone fragments researchers previously thought were created by ancient humans in East Africa.

Scientists have used what they call intentionally produced sharp-edged stones as proof of the evolutionary development of emerging humans. They used the “flake technology” to infer the degree of cognitive ability, including knowing how to select the types of rocks to give specific properties for making tools. Despite this “new” research, experienced field workers had previously observed monkeys inadvertently producing stone flakes and sometimes even using them as grooming tools.

Today’s anthropologists have moved beyond tool use to determine whether a specimen was human. They can sometimes use DNA found in the remains of the individuals. DNA studies have led to the understanding that all humans are related and that the gene pool has been thoroughly mixed over the ages.

The biblical reference is very simple. The name “Eve” means the mother of all living humans (Genesis 3:20). “Adam” means “of the ground,” referring to the fact that our physical bodies consist of elements found in the earth. “In the sweat of your face shall you eat bread until you return to the ground, for out of it you were taken. For dust you are, and to dust you shall return” (Genesis 3:19).

What sets humans apart is not tool use but our spiritual makeup. All humans are made in the image of God. We are all one physically, and the Bible calls us to become one spiritually. (See Galatians 3:28 and Ephesians 2:14.)

Spring Green Testifies of God

Spring Green Testifies of God

I have been admiring the beautiful colors of the blossoms on our fruit trees and the flowering dogwoods. Spring brings new life to the natural world. Everything changes daily as the bulb plants wake up and emerge from the ground. Yet, even with all the beautiful colors, I enjoy spring green. 

Green is a very relaxing color. The new leaves on the trees transform them from ghost-like stalks to luxurious, living umbrellas ready to provide shade from the summer heat. But, have you ever noticed that the green of tree leaves seems more vibrant in the spring than in summertime? There is a reason for that. It isn’t just your imagination.

Leaves are green because of the chlorophyll they contain. That amazing chemical makes it possible for plants to take energy from the Sun, moisture from the ground, and carbon dioxide from the air to make sugars that power their growth. We call that extremely complex process photosynthesis, and we have discussed that before on this website. The chlorophyll is contained in chloroplasts in the leaves. The chloroplasts absorb light, but they use more of the higher energy blue and red wavelengths and reflect much of the green. When we see spring green leaves, they contain fewer chloroplasts, so they absorb less light, making the green leaves appear bright and vibrant.

Chloroplasts multiply as the season wears on, so the leaves absorb more light. Also, the cuticles, or outer layer of the leaves, and the cell walls in the leaves become thicker. Those factors, which are part of the leaf’s maturing process, cause it to appear darker. I wonder if we also become less conscious of the green after we have seen it for a few weeks. When the dark tree trunks of winter become hidden by beautiful green leaves, we take notice. Our attention changes when we have seen the spring green and become overwhelmed by the summer.

In autumn, when the chloroplasts fade, the vibrant colors of other chemicals in the leaves catch our attention. Spring green and autumn gold and red can jar us into realizing the beauty of the world. However, we should not need sudden changes to make us conscious of the beauty of God’s wonders all around us. Evidence for God is there if we are willing to look. “For his invisible attributes, that is, his eternal power and divine nature, have been clearly seen since the creation of the world, being understood through what he has made. As a result, people are without excuse” (Romans 1:20 CSB).
