Astronomical Events and Halloween

We previously discussed the religious history of Halloween, but it also has a connection to astronomical events. Halloween is a cross-quarter day halfway between the equinox and the solstice. The equinox is when day and night have equal lengths, and the winter solstice is the shortest day and the longest night. (Groundhog Day is also a cross-quarter day.)

Humans find all kinds of reasons to celebrate visible astronomical events. Some cultures have given each of the seasonal cycles some great religious significance. Neolithic builders erected Stonehenge in Wiltshire, England, over a period of 1500 years, perhaps to commemorate the summer and winter solstices. That structure shows a great understanding of the equinox and solstice, and it was, and still is, a place of worship.

Other cultures have used astronomical events to govern their religious beliefs. The pyramids of the Egyptians and the Aztecs are examples, and there are many others. Even the celebration of Christmas has astronomical connections to the winter solstice. Several cults have tried to attach great significance to astronomical events, almost always with disastrous results.

The Bible makes it clear that the followers of Jesus must not be swept up in the celebration of heavenly bodies. Acts 1:7 tells us, “It is not for you to know the times or the seasons, which the Father has put in his own power.” The message of Christ is a spiritual one, not locked into watching what happens with the Sun and the Moon. Colossians 2:16 tells Christians, “Let no man, therefore, judge you in meat, or in drink or in respect of a holy day, or of the new moon, or the sabbath days.”

It isn’t that Christians aren’t interested in what happens in the design and function of the universe, but we are warned not to engage in idolatry. Worshipping and serving created things rather than the Creator is idolatry (Romans 1:25). God’s word is the guide we should follow.

Neanderthals and the Bible

In 1856, workers in Neander Valley near Dusseldorf, Germany, discovered a cave containing human bones that were different from modern humans. Scientists gave those bones the name Neanderthal, which means “Valley of the New Man.” We have written about this before (such as HERE, HERE, and HERE), but how can we reconcile Neanderthals and the Bible?

Since that first discovery, anthropologists have found Neanderthal remains throughout Europe and elsewhere. Neanderthals had large brains, thick bones, and muscle attachments, indicating high strength. The age of these specimens is much greater than any written human communication. They lived a nomadic lifestyle and dwelled in caves and natural shelters. They did not have cities or build sophisticated structures, but recent studies show intelligent behavior, including mastering fire for cooking, controlling animals, and providing warmth.

Genetic studies show that modern humans had Neanderthal ancestors. Some writers claim that Neanderthals were humans physically but had no soul and, thus, no spiritual awareness. That raises the question of how Neanderthals connect with Adam in Genesis 1 and 2. Those who promote theistic evolution say that ape-like hominoids evolved. Then, when these individuals reached a certain level, God infused them with a soul and called them “Adam,” Hebrew for “of the ground.” Some claim that Cain encountered Neanderthals in the area that Cain was banished to in Genesis 4:14 and following.

The point is that rather than deny that Neanderthals existed, we need to realize that there are many possible ways to reconcile Neanderthals and the Bible account of Adam and Eve. As scientists make more discoveries, the picture may become more evident. Meanwhile, we know the biblical account is valid and not at odds with findings about human history.

Transplanting Animal Organs into Humans

On September 20, 2023, Lawrence Faucette had a pig’s heart transplanted into his body to replace his own heart, which was in total failure. Xenotransplants, transplanting animal organs into humans, have been tried in the past, but the patient’s immune system destroyed the transplanted organ. Faucette’s animal heart came from a pig that was genetically modified to make it more human-like. After a month, there has been no sign of rejection, and Faucette is in physical therapy. The medical science community is interested in xenotransplants because there is a massive shortage of human organs for transplantation. (Update: Unfortunately, Mr. Faucette passed away on October 30, 2023.)

Many people have questioned the religious implications of xenotransplants. Various Bible passages speak of the human heart but not the physical organ. The Old Testament uses the Hebrew word for “heart” 851 times, primarily referring to the mind of an individual. There are a few cases, like Absalom in 2 Samuel 18:14, Nabal in 1 Samuel 25:37, and Joram in 2 Kings 9:24, where the physical heart is intended. In the New Testament, when Jesus talks about the “pure in heart” in Mathew 5:8 or refers to hard hearts, as in Mark 3:5, these are clearly not references to the physical heart.

The bottom line is that God is not primarily concerned with the physical organ but with our thinking, attitude, compassion, and capacity to love and serve. What happens to a person’s body is that it will eventually return to the Earth from which it came. Abraham said in Genesis 18:27, “I am but dust and ashes.” Solomon wrote in Ecclesiastes 12:7, “Then shall the dust return to the earth as it was: and the spirit shall return to God who gave it.” The psalmist wrote, “we are dust” (Psalms 103:14), and we “die and return to the dust “(Psalms 104:29).

Doctors have used valves from pig hearts for a long time, with great benefits for those who receive them. Understanding God’s design and creative wisdom opens the door for transplanting animal organs into humans, providing ways to make a human’s short tenure on Earth more pleasant. However, it is ultimately our soul and relationship with God that is of primary concern. Jesus made that abundantly clear when He said, “Do not fear those who kill the body but are not able to kill the soul: but rather fear him which is able to destroy both body and soul in hell” (Matthew 10:28).

Is Moderate Drinking Good for You?

Have you seen media reports claiming that alcohol is good for you? It turns out that the studies that led to those headlines were severely distorted by poor sampling. Those studies linked all nondrinkers together and called them all “abstainers.” Some of them were recovered alcoholics who had quit drinking. Others were non-drinking substance abusers or those suffering from chronic illnesses. Meanwhile, the “moderate drinkers” in the study could include those who ate healthy and exercised. More balanced modern studies answer “Is moderate drinking good for you?” with a “NO!”

Based on more non-biased studies, by 2022, the World Heart Federation stated that alcohol did not protect people from cardiovascular diseases. The World Health Organization (WHO) has now stated that any amount of alcohol is dangerous. U.S. and Canadian authorities have lowered their definitions of “moderate-risk drinking.” A growing body of research says that any amount of alcohol raises the chance of premature death from various causes. Here is what is now known:

Half of all cases of liver disease are attributed to drinking.

Alcohol is a potent carcinogen because it breaks down in the body to form a compound called acetaldehyde, which damages DNA.

Fifteen percent of breast cancers are linked to alcohol.

In Europe, 50% of all cancers linked to alcohol are caused by “light” or “moderate” consumption.

The distressing thing about this is that young people are bombarded with messages and music glamorizing drinking. Television shows encourage drinking by showing a glamorous picture of people drinking alcohol. The health damage and risks from alcohol consumption are not presented to young people in any educationally sound manner.

Biblical teaching tells us that the body is the temple of God’s Spirit and must be cared for and protected (1 Corinthians 3:16). The Church should lead in education, especially with teens and young adults. So far, that has not happened, and the whole basis for not drinking is frequently lost in discussions about “moderation.” Is moderate drinking good for you? No, and beyond that, “There is no safe amount that does not affect health” (WHO).

Solar System Formation

NASA released a fascinating picture showing solar system formation. The star in the picture is PDS 70, and the resolution is so good that a planet orbiting the star is clearly visible. Also visible is a disk around the planet, apparently forming several moons.

This picture shows what astronomers believe was the process that produced Jupiter and some of its moons. This is the first time astronomers have seen a solar system formation in progress. The amazing thing about this is that it is very reminiscent of the Bible’s description of the process God used to produce the Earth and the other objects in our solar system.

Genesis 1:1 uses the Hebrew word for creation (bara), which describes a process that only God can do, creating something from nothing. Modern science has now shown that time, space, and matter/energy came into existence at a point called a singularity, but can’t answer what went on before this singularity. From verse 1 through the rest of Genesis chapter 1, the word “bara” is not used until verse 21, when God created the first animal life. The term used elsewhere is “asah,” which describes changing something already created. (See verses 7, 16, and 25.) The word “bara” is used again in verse 27, when God created man and woman in his own image. Chapter 2, verse 3 summarizes what God had done by saying that He rested from all He had created (bara) and made (asah).

What we are now seeing is how material already created is crafted into a solar system. We may never know what purpose God has for these other solar systems. However, watching this solar system formation helps us understand the formation of our solar system and our unique planet. We know that our giant gas planets (Jupiter, Saturn, Uranus, and Neptune) are strategically placed to protect Earth from collisions by comets and other objects coming from outside our solar system.

In Psalms 8:3-4 we read, “When I consider the heavens, the work of your fingers, the moon and the stars which you have set in place, what is man that you are mindful of him,…” We don’t see the answer to that question in the physical processes God has used and continues to use. The significance of humans and Jesus Christ’s teachings reveal God’s spiritual purposes in the creation.

The horrible wars wreaking havoc among humans in today’s world are caused by the evil that combats the good Jesus came to establish. While the world is embroiled in war, selfishness, power struggles, greed, and death, we see God working in the lives of men and women and the good being done by the people who faithfully follow Jesus.

Incredible Color in Birds and Trees

One of the great mysteries of living things is the presence of beauty. If your faith is “survival of the fittest,” you have no explanation for beauty. Things in the natural world often radiate incredible beauty that has no survival benefit or even threatens survival. The incredible color in birds and trees provides a classic example. Some birds have gorgeous colors that can make them vulnerable to predators.

Here in Michigan, we are witnessing another example of beauty with no survival value but seems designed for humans to enjoy. The green color we see in plants is due to chlorophyll, which allows plants to use photosynthesis. There are two kinds of chlorophyll molecules called chlorophyll A and chlorophyll B. Chlorophyll A absorbs blue light, and chlorophyll B absorbs red light. Green light is the highest energy of sunlight reaching Earth’s surface. Plants are green because the green light radiation is reflected away to protect the plants. In the fall of the year, the chlorophyll in the leaves is removed, and we see the remaining colors.

These facts explain why trees are green and the wisdom in the green color of chlorophyll. But why do the leaves have different colors when the chlorophyll is removed? In our area, the first fall colors that appear are the reds of sumac and poison ivy. Depending on the variety, maple trees have various colors of red, orange, and yellow. We also have multiple birch tree varieties, each with different fall colors.

Why should there be different colors we can’t see until the chlorophyll is gone? The chemistry that creates these colors is very complex. From an evolutionary view, all trees would have the one pigment that advances survival, but that is not the case. The picture gets even more complicated when we consider plants that never see sunlight, such as ferns and various grasses.

As we enjoy the incredible color in birds and trees, we can see beauty for the spiritual value it offers and the joy it brings. That is because we are created in the image of God, the creator of beauty.

For a detailed discussion of chlorophyll, see Wikipedia.

AI Is a Huge Threat to Humanity – Or Not

The media thrives on exaggerations and misrepresentations involving doomsday scenarios. One of the biggest movies when I was a teenager was titled “When Worlds Collide.” It was a science fiction story of a rogue star and its planet hitting and destroying the Earth with only a select group of humans escaping. A recent popular movie was built around the scientists developing an atomic bomb while fearing it would destroy the Earth. Several media presentations have suggested that Artificial Intelligence (AI) will wipe out humanity. Media outlets like The Guardian, The New York Post, Entrepreneur, and the BBC have all indicated that AI is a huge threat to humanity.

Artificial Intelligence is the simulation of human intelligence processes by computer systems. Science fiction has long postulated that machines will replace humans and rule the world. Many science fiction stories revolve around non-human enemies of humanity or heroes such as R2-d2 and C-3po. What can computers do or not do? Is it true that AI is a huge threat to humanity?

AI can do some jobs faster and with greater accuracy than humans. Computers can build and run automation systems, causing the loss of human jobs. Computers can process languages more quickly than humans. They can also process numbers faster and more accurately, meaning that AI can predict economic change, develop weaponry, and invade human privacy quickly and efficiently. AI can create images, both authentic and false, and even produce videos known as deepfakes. AI can deliver fake news with video support that is so good humans can’t tell what is real and what is fake.

As we consider whether AI Is a huge threat to humanity, we must understand that the dangers are philosophical and not inevitable. There is an adage about computers that says, “garbage equals garbage out.” Building computers capable of producing AI requires intelligence and design by humans. Like almost everything humans create, we can use AI to mislead and damage or to improve people’s lives. As in everything else, we desperately need people guided by the teachings of Jesus to make the decisions about how we will use AI.

Annular Solar Eclipse

If you were in the path of the annular solar eclipse on Saturday, October 14, 2023, and had a clear sky, you were privileged to see something that won’t happen again until 2039. In an annular solar eclipse, as opposed to total or partial eclipses, the Moon passes directly between the Sun and Earth without totally blocking the Sun. That is because the Moon is at a distant point in its eliptical orbit. Because of that, it appears slightly smaller, so its shadow cannot completely hide the Sun from our view.

The Moon and Sun are on the same side of Earth once every 29.5 days. We call that event the “new moon” because it is invisible to us. When the Sun and Moon are on opposite sides, we see the monthly “full moon.” Because the orbit of the Moon is 5 degrees off from the Sun’s path (which we call the ecliptic), the Moon rarely falls precisely between the Sun and Earth. When it does, we see a total solar eclipse. When it is a little off from directly blocking the Sun’s light, we witness a partial solar eclipse. We have an annular solar eclipse on those rare times when the Moon is directly in front of the Sun but at its farthest distance from Earth (known as apogee). We see the “ring of fire” around the Moon’s shadow, which is what happened Saturday.

Although the lower 48 United States all experienced a partial eclipse, those in the direct path of the Moon’s shadow witnessed an annular solar eclipse. It began in Oregon, traveled across several western states, and exited from Texas into the Gulf of Mexico. It then covered several Central and South American countries before leaving into the Atlantic Ocean from Brazil. Millions of people could view this annular eclipse. In the U.S., the eclipse crossed several national parks, including Bryce Canyon, where Does God Exist? has often taken groups on our Canyonlands tours.

The wonderfully amazing thing is that we can accurately predict solar (and lunar) eclipses hundreds of years, even a thousand years into the future. That is because we live in a precision-designed universe and solar system. The next solar eclipse crossing North America will be a total eclipse at 2:10 p.m. Eastern time on April 8, 2024. You can put that on your calendar.

Eclipses have taught us many things about our Sun and the solar system design. Regardless of what some people may try to tell you, eclipses are not prophetic signs. They are part of God’s design for a planet where life can live and prosper.

The Red Giant Star Mu Cephei

When you look at the astronomical data on the red giant star Mu Cephei, you can’t help but be amazed at the size and power of things we can see in the cosmos. We read passages like Psalms 19:1, “The heavens declare the glory of God; and the firmament shows His handiwork.” The Hebrew word “glory” is “kabod,” and the lexicon’s first use of that word is weight or power. Mu Cephei is an incredible demonstration of the power of the Creator.

If we could put Mu Cephei in the place of the Sun, the orbit of Jupiter would fit inside it. That means the size of this one star, which is relatively close to the solar system (2800 light years), would exceed the orbits of Mercury, Venus, Earth, and Mars. If our understanding of stellar evolution is correct, this giant star will eventually collapse into a supernova, producing the elements you and I are made of. We now understand that the stuff we see, the elements that make up everything on Earth, are only 5% of the universe. The European Space Agency’s Planck satellite has revealed that 68% of the cosmos consists of dark energy, 27% is dark matter, and only 5% is atomic matter. So the red giant star Mu Cephei and everything else we can see is only a tiny part of the cosmos.

Science has just scratched the surface of comprehending the fundamental nature of the universe. The words of Psalms 8:3-4 are magnified by what we see as we look into space with our instruments and technology: “When I consider your heavens, the work of your fingers, the moon and stars which you have ordained, what is man that you are mindful of him and the son of man that you visit him.” The only answer that can come to thinking people is that we are summoned to a higher calling than the physical world in which we live.

After Job’s complaining, God answered him by saying, “Who is this who darkens counsel by words without knowledge?” Then, God challenged Job with many questions about creation in chapters 38 to 41. Humbled, Job responded, “Therefore I have uttered what I did not understand, things too wonderful for me, which I did not know.” Using our technology, we can examine the red giant star Mu Cephei and know much more about creation than Job ever could. But there are still many wonderful things that we do not know.

Art and Science – Faith and Science

Brian May cofounded the rock band Queen along with Roger Taylor and Freddie Mercury. He is known as one of the greatest guitarists in the history of rock music, and he is also an expert in astrophysics and a consultant to NASA. May combines his art and science, earning a Ph.D. in astrophysics in 2007 with a thesis involving the study of zodiacal dust, which fills interplanetary space in our solar system.

May worked with NASA on the asteroid sampling mission OSIRIS-REx. Finding a safe landing spot to take samples of the asteroid Bennu was one of the most significant challenges of the mission. May found a way to use images captured by OSIRIS-REx’s cameras and process them into 3-D images showing the rugged contours of the asteroid. Those images allowed NASA scientists to decide where to land the probe.

In a National Geographic interview, Nadia Drake asked May about his approach to art and science and how he combines these two fields. May made an interesting statement about his personal approach to this issue:

“This is central to my life and my beliefs. I was told that I couldn’t do art and science as I progressed through school. I was very resentful about that because I loved them both. I feel like the rest of my life has been trying to prove them wrong. More and more and more, I’ve discovered that artistic thinking and scientific thinking are just different parts of the same thing. It’s a continuum. They’re inextricably linked. You have to have both sides to function at your full potential.”

According to Wikipedia, May describes himself as an agnostic, but his approach to linking art and science can apply to faith and science. Our quarterly magazine has a regular column in which leading scientists explain how they mesh faith and science. Those who try to use science to destroy faith are making a fundamental error. Our faith in the Creator makes us want to learn more about the creation. At the same time, science is a great tool to grow one’s faith because the more we know of the creation, the closer we get to the Creator.
