Astrolabe Shows Human Cooperation

The astrolabe, an astronomical instrument of ancient times, is a testament to human ingenuity and cooperation. It is a two-dimensional map of the universe, typically crafted from plates. Astrolabes, with their star charts and analog calculation capabilities, were not just tools but gateways to understanding the cosmos. In mosques, they were used to calculate the time of sunset or sunrise, thus the time of prayer. People also used them to calculate distances, the position of stars, and the location of latitudes and longitudes. With its intricate design and multifaceted functionality, the astrolabe shows human cooperation.

Federica Gigante, a historian at the University of Cambridge, found the plates of an eleventh-century astrolabe in the vaults of the Museum of the Miniscalchi-Erizzo Foundation in Verona, Italy. The astrolabe she discovered was made of brass and had Arabic engravings. It had a second plate, which meant it had been taken to a different latitude than its Spanish place of origin.

What is interesting about this astrolabe is that it also has Hebrew letters engraved on the plates, indicating their use by Jewish owners, and it was in the archives of a Christian museum. This astrolabe shows human cooperation. It means there was an era in which Muslims, Jews, and Christians built upon one another’s intellectual achievements. All cultures had people with incredible minds who contributed to human knowledge of what the cosmos is about and how we can observe it.

In our day of religious wars between these same groups, it is incredible that humans don’t have the sense to realize the importance of understanding each other and working together to discover Truth. Jesus gave a great answer to this conflict in John 14 when He said, “I am the way, the truth, and the life. No man comes to the Father but by me… If you love me, keep my commandments… even the Spirit of truth whom the world cannot receive because it has not seen Him and does not know Him, for He dwells in you and shall be in you.” Think of the progress the world could make if we could work together and follow the commandments of Jesus given so clearly in Matthew 5:21-25 and 38-48.

Media Hype About Exoplanets

The media continue to make scientifically inaccurate claims to an unsuspecting public. Media hype about exoplanets suggests that life on Earth is not unique, and many habitable planets exist throughout the cosmos. A USA Today article on May 31, 2024, refers to exoplanet Gliese 12 b as a “super-Earth.” It quotes Dr. Masayuki Kuzuhara, assistant professor at the Astrobiology Center in Tokyo, saying, “Although we don’t know whether it possesses an atmosphere, we’ve been thinking of it as an exo-Venus with similar size and energy received from its star as our planetary neighbor in the solar system.” So, what are the facts about Gliese 12 b?

Gliese 12 b is very close to the star Gliese – just 7% of the distance between the Earth and the Sun. That means the radiation from the parent star is sweeping across the planet, and because it orbits once every 12.8 days, any activity on the star will dramatically affect the planet. Gliese is a red dwarf star, not a star like our Sun. It is only 27% of the size of our Sun, with about 60% of the Sun’s surface temperature. Red dwarf stars do not emit wavelengths of light needed for life forms like us. Understand that life cannot exist when the only light reaching the planet is Xrays, UV, Infrared, and radio waves.

Considering all these factors, it is highly improbable that Gliese 12 b has an atmosphere, and the presence of water, oxygen, hydrogen, or ammonia has not been detected and is unlikely to be found. Despite the media hype about exoplanets, there is no scientific evidence to support the existence of life without these elements.

Critics will say, “Maybe the life forms out there are not like us and can survive under different kinds of radiation.” Life is defined as that which can move, breathe, respond to outside stimuli, and reproduce. If you want to speculate that life can be fire people or stone people, you can do so, but scientifically, such hypothetical forms do not qualify as “life.” There is no evidence anywhere that such forms exist.

When you know the facts of what life requires, you cannot logically believe that life forms different from ours can exist in the physical creation. Media hype about exoplanets suggests alternatives that have no scientific support. Science supports Genesis 1:1: “In the beginning, God created the heaven (space) and the Earth.”

Earth Is a Very Special Place

As of May 9, 2024, astronomers have discovered 5,616 planets orbiting other stars. Of that number, 1794 are “gas giants” like Jupiter, 1,920 are Neptune-like planets, and 1,695 are “Super-Earths,” solid planets like Earth, but much larger. That means they will have denser atmospheres of gases that are inhospitable to life. That leaves 207 terrestrial planets, of which seven have unknown features. As the James Webb telescope gathers data, these numbers will change, but the message is already clear. Earth is a very special place, and most of the exoplanets we see are unsuitable for life of any kind. By life, we mean the usual biological definition – that which can move, breathe, respond to outside stimuli, and reproduce.

Hollywood, TV, and books have given us some creative fantasies about space travel, but there are specific limitations on where humans can go. The closest star to Earth is 4.3 light years away, meaning that if you could travel at the speed of light, which is impossible, it would take 4.3 years to reach that star. The closest major galaxy to our Milky Way is Andromeda, 2,480,000 light years from Earth. That means the light coming to us from Andromeda left there 2,480,000 years ago. Humans traveling to Andromeda at the speed of light would need that long to get there. The return to Earth would take just as long, and the Earth would have aged 4,960,000 years while they were gone, even though time would have slowed for the travelers.

All of this is to say that traveling to another galaxy and back is pure fantasy and not an option for any of us. It also says that alien visits to the Earth are another fantasy that may make good movies but are not supported by evidence or common sense. Some people suggest that we are not alone and that aliens are affecting human activities, but that is a fantasy we cannot seriously consider.

The ancient psalmist wrote, “When I consider Your heavens, the work of Your fingers, the moon and the stars, which You have ordained, what is man that You are mindful of him, and the son of man that You visit him?” (Psalms 8:3-4). Another Psalm says, “The heavens declare the glory of God; the skies proclaim the work of His hands” (Psalms 19:1). The ancients wrote about what they could see, but now we can see so much more. We are blessed with a whole different picture of the size, power, and wisdom of God’s creation as we realize that Earth is a very special place.

We Look Up and See a Blue Sky

Most of us underestimate the design of planet Earth. We look up and see a blue sky and take it for granted, but having a blue sky is unique to our planet and tells us much about its design.

We must first understand that a change in electric charge produces light. The amount varies depending on the amount of change. Small changes produce light that is low in energy and may not be visible to human eyes. Radio waves are light we cannot see. Infrared waves are light humans can’t see, but numerous animals can. For example, a rattlesnake can see infrared light coming from a mouse even though human eyes would say there is no light. The mouse gives off infrared due to its biological processes, and the snake can see it in the dark. We call infrared light radiant heat.

A large change in an electric charge produces light that is too energetic for our eyes to see. Xrays, ultraviolet, and gamma rays are the words we use to describe these high-energy forms of light. They can expose a photographic plate and penetrate most organic tissue, possibly causing damage. The light our eyes are designed to see has lower energy than Xrays and higher than radio waves. This beautiful design of our eyes means we cannot see through most solid materials like wood, metal, or human flesh.

Light from the Sun arrives on Earth with all of these energies present. The Earth’s atmosphere is dense enough to prevent the high-energy forms of light from reaching the surface. That means we are not fried by the X-rays, gamma rays, or even excessive ultraviolet light coming from the Sun. The highest visible light that our eyes can see is blue. As blue light enters our atmosphere, it is scattered and refracted away by atmospheric materials. We look up and see a blue sky.

Green is the next highest energy reaching the surface. Plants are protected from damage because their chlorophyll reflects green light. When tree leaves lose their chlorophyll in autumn, the green disappears, replaced by other colors hidden within the leaf structure. Then, the leaves fall off to prepare the tree for winter. Annual plants shrivel and die while perennials retain their root structures to bring color back in the spring.

So we look up and see a blue sky. On the Moon, we would see a black sky. On Jupiter, it would be red. The atmosphere on all the other planets gives a color other than blue. Astronauts face huge dangers when leaving Earth’s atmosphere with its well-engineered light-handling design. To live on the Moon or Mars, human engineers must build elaborate designs to imitate what God created to allow us to live on Earth. That is the greatest challenge to space travel and a great demonstration of God’s wisdom.

Fungi Are All Around Us and Even Inside Us

The cover of the April 2024 issue of National Geographic and its first article are dedicated to what the editors call “Fabulous Fungi.” The articles deal with “The Wondrous World of Fungi” with incredible pictures and a narrative that exposes what the authors call “The Hidden Kingdom.” Most of us probably don’t realize that fungi are all around us and even inside us.

Various fungus species have a symbiotic relationship with many plants and animals, including humans. Most plants today depend on mycorrhizal fungi living in their root systems to metabolize sugar from photosynthesis while bringing nutrients and water to the plant.

Fungi are heterotrophs, organisms that take nutrition from other organic sources such as plant or animal matter. They can break down wood and dead plant material by releasing and reabsorbing enzymes. Without fungi, dead plants and animals would pile up on forest floors, and plants would be unable to take in needed nutrients.

Fungi are all around us and even inside us. They work in our digestive system, and scientists are still studying what they do. Cancer research has found that fungi in the colon, breast, and lungs are related to the metastatic spread of cancer and can be used to predict the presence of cancer and perhaps even treat it.

Scientists estimate that there are around five million species of fungi, and they are more diverse than plants or vertebrates. In 2015, our program released a children’s book titled “The Friendly Fungus Among Us,” written by Charlsey Ford and John Clayton. This little 16-page booklet, written for children, points out a few benefits and uses of fungi, including food, medicines, insecticides, and detergents. It also introduces children to the role of yeast and truffles in food.

God’s design is so incredible that science is just scratching the surface of the things that enable human life to exist on Earth. Trying to explain it by undirected evolution is impossible. “We can know there is a God through the things He has made” (Romans 1:20) is true. We see evidence everywhere, even in the fact that fungi are all around us and even inside us, and life would not be possible without them.

Lessons from America’s Total Solar Eclipse of 2024

Watching yesterday’s news reports of the total solar eclipse, I was impressed by how many people called it a “spiritual” experience. People said that it made them realize how small we are. Many indicated that it brings people together to remind us that we need each other. Some spoke about it being a testimony to the existence of God. Lessons from America’s total solar eclipse of 2024 teach us about God’s power and the brevity of life.

In 1815, American novelist James Fenimore Cooper wrote, “…never have I beheld any spectacle which so plainly manifested the majesty of the Creator, or so forcibly taught the lesson of humility to man as a total eclipse of the Sun.” Modern eclipse chaser Kate Russo said about the total solar eclipse,” You don’t need to know anything about it to feel that overwhelming sense of awe.” She is a clinical psychologist who has studied how eclipses affect people and wrote a book titled “Being in the Shadow: Stories of the First-time Total Eclipse Experience.”

Multiple news commentators remarked about the amazing coincidence that the Sun is 400 times the size of the Moon but 400 times as far away. That “conincidence” allows the Moon to exactly block out the Sun, allowing us to see see its corona. That fact is one of many “coincidences” that enable us to study and learn about God’s orderly creation.

Many people experienced awe as they watched the eclipse. Dacher Keltner of the University of California, Berkeley, is described as a “pioneer in the science of awe.” He defines awe as “the feeling of being in the presence of something vast that transcends your understanding of the world.” Lessons from America’s total solar eclipse of 2024 fill us with awe.

My wife and I took my brother, his son, and grandson to southern Illinois to view the total eclipse of 2017. We agreed to return to the same area in seven years to observe the 2024 total eclipse. We were unable to do that because my brother and his son passed away. My wife and I could not make the trip due to health issues and had to enjoy a partial eclipse from our home. It will be two decades before a total solar eclipse crosses the United States again. There is no question that lessons from America’s total solar eclipse of 2024 teach us about God’s creative power and the brevity of life.

Weather Can Surprise Us But Eclipses Do Not

Today is the day of the 2024 total solar eclipse in North America. People have traveled to locations where they can view it, and great crowds will gather in many locations. For many, it will be a thrill to watch. For others, it will be a disappointment because of the weather. Despite improvements in weather radar and computer data, weather can surprise us, but eclipses do not.

In 1970, a total eclipse was predicted to cross Perry, Florida. Although the town had only about 8,000 residents, the Perry Chamber of Commerce wanted to promote its location for eclipse watching. They ran print ads saying that Perry was “in the center of the eclipse,” and the long-term weather data indicated there would be a 70% chance of clear skies with a temperature of 72 degrees on eclipse day. That advertising convinced more than 25,000 people to come to Perry to view the eclipse.

Among the people who flocked to Perry were scientists from around the world who came with cameras and equipment. While tourists came to enjoy the eclipse, scientists came to study the Sun and its corona, which is only visible during a total eclipse. Swiss astronomer Max Waldmeier, director of the Zurich Observatory, brought a research team. The eclipse happened as predicted. However, the sky was densely overcast. Waldmeier and his team were bitterly disappointed as they packed their equipment to return home.

If we learn one thing from this, it is that weather can surprise us, but eclipses do not. What can we learn from eclipses? By studying total eclipses, scientists confirmed Einstein’s theory that gravity bends light waves. This led to the creation of accurate Global Positioning Systems (GPS). Also, total eclipses allow scientists to study the Sun’s corona and observe solar flares. For average people, eclipses show us that God’s creation is predictable and observable.

Everywhere we look, creation displays evidence of a wise Creator. The total eclipse also reminds us that we depend on the Sun. We can survive for a few minutes while it is hidden, but we depend on it for life daily. Likewise, we depend on God to supply the very things we need to survive each day. How often do we recognize that fact and show our gratitude for those blessings?

There Is No Experience Like a Total Solar Eclipse

On Monday, April 8, 2024, millions will see a rare occurrence as a total solar eclipse travels across North America. Those living outside the totality path will see a partial eclipse, but, as we said yesterday, it won’t be the same. There is no experience like a total solar eclipse.

April 8 will bring in the “new moon” when the Sun, Moon, and Earth line up, with the Moon in the center. The Moon will block light from the Sun, creating a shadow that will travel across the Earth’s surface. The shadow will be about 9,000 miles long, 115 miles wide, and traveling at a speed exceeding 1500 miles per hour. If you are in the total shadow (the umbra), you will experience the total eclipse. Most of the United States will be under the outer shadow (the penumbra), and people living there will experience a partial eclipse.

I said there is no experience like a total solar eclipse. Eclipse watchers outside the path of totality will see a portion of the Sun obstructed by the Moon, with less obstruction farther from totality. People may also see a reduction in the light level, which is more significant near the totality path. Near the path, they may also notice a slight decrease in temperature. Let’s compare that with the experience of totality.

We emphasize that you must never look directly at the Sun without using approved solar eclipse glasses. If you are outside of totality, you must always use them when viewing the eclipse. However, during the brief minutes of totality, when the Moon completely obscures the Sun, you can take them off. In fact, you should take them off to see the Sun’s beautiful corona. That corona is one of the reasons why there is no experience like a total solar eclipse.

During totality, the darkness will be like deep twilight with a noticeable drop in temperature. You may hear night-time sounds as birds and other animals take on twilight behavior. Since the Sun is currently in a very active stage, you may see pinkish solar flares along with the corona. Some of the brighter stars or planets may become visible.

If you are on the edge of the shadow or as the Moon starts to move away from totality, the light you see may be affected by the mountains and valleys on the Moon. The effect is called Baily’s beads, as beads of light become visible between the Moon’s geological features. At the moment the Moon begins to move away from total coverage of the Sun, you may see an effect called the “diamond ring” as the Moon’s mountain features allow a larger bead of light to emerge. I took the above picture of the diamond ring during the 2017 eclipse.

I want to emphasize that there is no experience like a total solar eclipse. Actor William Shatner, Captain Kirk of the original Star Trek series, is scheduled to appear in the Hoosier Cosmic Celebration at Indiana University in Bloomington on eclipse day. He said, “To me, the magic of the eclipse, the extraordinary events it all took in the heavenly bodies to cause this eclipse, should make us ponder the mystery of existence, of our own existence, of the existence of everything else…”

I agree with Shatner’s words, but I would go further. The eclipse should cause us to ponder the existence of God, who created the heavenly bodies and put them in motion. It should also cause us to ponder the purpose of our own existence and our relationship to the Creator.

Earthquake Catastrophe Risk

The United States Geological Survey published a map showing the earthquake catastrophe risk in different parts of the country. This data comes from seismic records of 130,000 earthquakes of a magnitude on the Modified Mercalli intensity scale of six or higher, which is severe enough to frighten people, move furniture, and cause other damage, like falling plaster. Most of us know about some geologically unstable regions of the country, but other areas may be surprising.

The highest earthquake catastrophe risk within the next 100 years is essentially the whole western edge of California, the southern part of Alaska from Juneau through the Aleutians, and the eastern islands of Hawaii. Those areas with a 75 to 95% chance of a damaging earthquake include virtually all of California, the Yellowstone National Park area, and the intersection of Missouri, Arkansas, Tennessee, and Kentucky. The study says that 230 million people live in areas with a 95% chance of a damaging earthquake.

The point of this data is that there will be a massive earthquake sometime in the next 100 years, causing death and structural damage. Many people will blame this coming catastrophe on God. The fact is that earthquakes are a natural product of the uplift of the land. Without those forces, erosion would have brought all land masses to sea level. Despite the data, humans continue to build huge structures in areas where earthquake catastrophe risk is high. This can be added to a long list of situations where humans set themselves up for a catastrophe.

My wife and I were on Hawaii’s “Big Island” when Kilauea erupted in May 2018. In one of the places we visited, lava flow had destroyed many homes. We happened across a man who was working on a new house. I asked him if he was not concerned that another lava flow might destroy this house. He laughed and said, “God wouldn’t do that to me twice.”

We need to understand that God does not cause bad things to happen to us. If you eliminate what humans do to each other and the foolish acts humans engage in (like building a house in the path of a lava flow or on an earthquake faultline), much human pain and suffering would stop. Read James 1:13-17.

Analysis of the Bennu Asteroid Sample

In 2016, NASA launched a spacecraft to the asteroid Bennu with the goal of collecting a sample and returning it to Earth for analysis. The canister containing the sample material arrived back on Earth last year. Everything worked fine until scientists tried to open the canister. Thirty-two screws held the container closed, and two of them were stuck. Scientists were cautious not to contaminate the asteroid material with Earth molecules, so they had to develop a new tool to remove the stuck screws. On January 10, 2024, they succeeded in opening the canister to analyze the contents. Analysis of the Bennu asteroid sample gave interesting results.

Some people have suggested that creation occurred in various regions of the universe with different materials. Those who promote that idea have maintained that chance, not creative design, formed the cosmos. They predicted that material from outer space would contain different elements arranged differently from what we see on Earth. The Genesis account maintains that creation is a singular act of God, and Proverbs 8:22-30 indicates that He used wisdom in the creation.

The Bennu minerals contain no elements that don’t exist on Earth, and the rocks formed by those elements contain no surprises. They contain serpentinite formed from olivine and pyroxene. Those minerals are familiar to anyone who has taken a petrology course. Analysis of the Bennu asteroid sample shows evidence of being formed by ice made of carbon monoxide and ammonia. That requires extremely cold conditions, which could only exist far from the Sun. Temperatures needed to form carbon monoxide and ammonia ice do not exist on any of the inner planets. So, Bennu was formed in the outer solar system beyond Mars.

We still have much to learn about how the formation of the solar system, and this research may be more critical as humans venture beyond the Moon into outer space. Even the possibility of establishing human colonies on other planets will depend on what materials are available there. Analysis of the Bennu asteroid sample is only the beginning. The more we learn about the solar system, the more we realize the importance of the unique features of Earth. It also reminds us of how essential it is to care for the planet God has given us.
