NASA posted this picture on apod.nasa.gov on April 8, 2019. Yang Suite took the photo in northern Norway of a phenomenon that lasted about 30 minutes. Witnesses said that colorful clouds, dots, and plumes suddenly appeared. Can you imagine what would have happened if the sky over Washington D.C. had been filled with what you see in this picture? Are they space aliens?
In this case, the picture is of a NASA-funded project called Auroral Zone Upwelling Rocket Experiment (AZURE). Gas tracers were dispersed from two short-lived rockets into the ionosphere at altitudes of 70 to 150 miles (112-240 km). The goal was to measure how the solar wind transfers energy to the Earth and powers auroras. Science still has much to learn about the design of the solar system and how something like an aurora takes place. So are they space aliens? No, and anytime we can see something that we don’t understand, we should seek to understand it and recognize the design and intelligence that is involved. The more we know of the creation, the closer we can get to the Creator.
I have a bicycle wheel that I use to demonstrate circular motion and forces to my physics students. Some of the forces that we can demonstrate seem to contradict common sense, but they are physical forces that make life possible.
The wheel has a handle on both sides. If you spin it rapidly and put one handle in the crotch of your hand between your thumb and first finger, you can completely let go of the other handle, and the wheel will stay in place, seemingly defying gravity. As the wheel slows down, it begins to wobble, and the slower it goes, the more rapid its turning motion is. This is called precession, and it applies to all spinning objects.
Several years ago when I was teaching this unit in my physics class, I did this demonstration. My class skeptic, who tried to make sure I knew he wasn’t impressed with anything I did, said: “OK – big deal, how does that mean anything to me?” My reply was that he wouldn’t exist if the universe had not been designed with these laws in place creating the physical forces that make life possible.
We live on a globe spinning at roughly 1000 miles per hour. The globe itself is revolving around the Sun at 67,000 miles per hour in a solar system that is orbiting the core of our Milky Way galaxy at 515,000 miles per hour. Each of those motions involves forces that make life possible. We would not have weather moving heat and moisture around the globe without the rapid spinning. The Earth would collapse into the Sun if we weren’t traveling at such an enormous speed. The solar system would collapse into the core of the galaxy and be absorbed by the black hole that holds our system together if we weren’t moving fast enough to avoid such a thing happening.
We understand these fundamental laws of physics, but our observations tell us that the picture we have painted here is oversimplified. Stars on the outer edges of the galaxy are circling at roughly the same speed as stars near the core, and that should not be happening. We know that there must be dark matter filling in for the lapses in speed that we measure. Either that or the darkness is simply in our understanding.
The reality of the motions and physical forces that make life possible on Earth are there for us to examine. However, the implications of what we see defy our imagination and speak of the reality of the God who designed and created it all.
The big news in environmental concerns for the past ten years has been the apparent rise in the average temperature of planet Earth. The planet has had more dramatic global warming and cooling in the past, but the magnitude of warming today has to be alarming to any thinking person who takes the time to look at the data. It seems likely that human contributions to global warming could be substantial, but the extent of human influence is still being debated. In any case, it seems wise to work toward minimizing what we do contribute. Research proves a relationship between trees, carbon dioxide, and global warming. The Creator has given us a cheap, effective, permanent solution to controlling the amount of carbon dioxide in the atmosphere. The answer lies in the trees that God gave us from the beginning. Here is some information about how trees can remove carbon dioxide from the atmosphere as presented in Scientific American, April 2019 page 7:
One tree can store an average of 48 pounds of carbon dioxide in a year.
If agroforestry were practiced, 9.28 gigatons of carbon dioxide would be sequestered by 2050. (Agroforestry is a land use management system in which trees or shrubs are grown around or among crops or pastureland.) Trees increase farm productivity and give farmers revenue through fruits, nuts, and timber while storing carbon dioxide.
Landscape restoration would sequester 1.7 gigatons of carbon dioxide every year.
There is a direct relationship between trees, carbon dioxide, and global warming. The bottom line is that keeping forests intact can go a long way toward saving the planet, and that just means taking care of what God gave us in the beginning.
Atheists frequently use Galileo as proof that religion is destructive and that good scientists don’t believe in God. In reality, Galileo is a poster child for the view that we try to present in all of our websites, videos, and printed materials.
Atheists have created a classic example of “fake news,” and the facts are undeniable in Galileo’s case. Galileo was a firm believer in God and the Bible, and he remained so all of his life. Among his most famous statements about science and faith were, “The laws of nature are written by the hand of God in the language of mathematics … The human mind is a work of God and one of the most excellent.”
Galileo argued that the Earth revolved around the Sun, not the other way around. That was in opposition to the way the church leaders interpreted the Bible. The Pope urged Galileo to present both sides of the argument in a book. The Pope insisted that since God is omnipotent, He could create natural phenomenon any way He wanted to. Galileo wrote the book as a dialogue between the two sides. He named the character presenting the argument in favor of an Earth-centered solar system “Simplicio” meaning “buffoon.” Galileo made the Earth-centered case seem dull-witted. That caused the Pope to put Galileo in the permanent isolation of house arrest. Galileo was never tortured, and his house arrest was in the hospitality of luxurious private residences belonging to friends.
The main point here is that Galileo is a poster child for the harmony of science and faith because he was a believer in the biblical worldview who advanced a better scientific understanding of the universe. C.S. Lewis wrote, “Men became scientific because they expected law in nature, and they expected law in nature because they believed in a Legislator.” Johannes Kepler who gave us the laws of planetary motion wrote: “The chief aim of all investigations of the external world should be to discover the rational order which has been imposed upon it by God and which He revealed to us in the language of mathematics.”
As the famous scientist Michael Faraday lay on his deathbed, a visiting friend asked him what his speculations were now that he knew he was dying. His response was “Speculations, man, I have none! I have certainties. I thank God that I do not rest my dying head upon speculations, for I know whom I have believed and am persuaded that He is able to keep that which I have committed to Him against that day.”
Since Galileo is a poster child for science and faith, you could also add Kepler and Faraday and several others.
When humans throw the world of plants and animals out of balance, the result is extinctions. We can destroy God’s designed balance when we introduce a non-native species into an environment. The introduced species without natural predators uses up local resources leaving native species without food. There are many examples.
One example is the brown tree snake (Boiga irregularis) which was accidentally introduced to Guam aboard a military cargo ship after World War II. Those snakes are native to Australia and Indonesia where natural predators control them. On Guam, they have decimated 50 percent of the native bird and lizard species and two of the three bat species on the island. The brown tree snakes considered those native species to be tasty treats, and the snakes had no predators to control them. The result was the extinction of many species, some of which existed nowhere else on Earth. Alien invasions of brown tree snakes forever changed the ecosystem of Guam.
In other cases, humans throw nature out of balance by their direct actions. An example of that is the over-hunting of sea otters. Sea otters kept the purple sea urchins in check. Steller’s sea cows (Hydrodamalis gigas)were giant relatives of manatees, and they lived on kelp. Without control by sea otters, the purple sea urchins ate so much of the kelp that Steller’s sea cows had no food, and they became extinct. However, the research project indicated that direct interference by humans in cases like this has less impact on extinctions than the alien invasions have.
Sometimes humans make the mistake of bringing in another non-native species to control the first one. That technique often makes the problems worse. Usually, by the time people discover the problem of alien invasions, it’s too late to fix it.
The research concludes that 25 percent of plant extinctions and 33 percent of animal extinctions were caused by alien invasions – the introduction of non-native species. The bottom line is that humans have not been good stewards of the planet God has given us to enjoy and protect. God gave humans the responsibility to have dominion over creation and “rule over the fish of the sea and the birds of the air and over every living creature that moves on the ground” (Genesis 1:28). Romans 13:1-4 indicates that those who rule over people have the responsibility to protect. We might say the same of us who rule over the creatures.
Although space-travel movies are exciting and fun, they are not very realistic. Einstein’s theory of special relativity says that it’s impossible to travel at the speed of light. There is overwhelming proof that he was right. That fact has an impact on the reality of space travel.
Astronomer Dr. Hugh Ross wrote an excellent book entitled Why the Universe is the Way It Is. In this book, he states that due to the laws of physics the top speed of a spaceship would be limited to about one percent of the speed of light, or 6.7 million miles (10.8 million km) per hour. Based on that, he says that for aliens to travel from any other planetary system where intelligent beings could possibly exist would take at least 25,000 years! (Remember that it will take nine months just to travel to Mars, our neighboring planet.)
So when you watch a two-hour movie in which people travel from one planetary system to another at hyper-light-speed, remember that it’s only Hollywood. The reality of space travel is not what we see in the movies. We live in a universe designed by a Creator who gave us a special place with everything we need to live. Is there any kind of life, not just intelligent life, anywhere else in this vast universe? We don’t know, but the chances of meeting intelligent beings from another planet are very, very slim. That’s the reality of space travel.
By the way, my picture is poking a little fun at a statement made by the well-known atheist biologist Richard Dawkins in his book The Selfish Gene. He begins chapter 1 by stating, “Intelligent life on a planet comes of age when it first works out the reason for its own existence. If superior creatures from space ever visit earth, the first question they will ask, in order to assess the level of our civilization, is: ‘Have they discovered evolution yet?’”
So does discovering evolution indicate advanced civilization and the level of our intelligence? More importantly, does evolution explain the reason for our existence? Personally, I think the reason for our existence is not found in evolution, but begins in Genesis chapter 1 and is developed in the rest of the Bible.
Today, March 20, 2019, is a special day as the spring equinox arrives for the Northern Hemisphere. Today the Sun will set exactly in the west and tomorrow it will rise exactly in the east when observed from the Equator. The day will be exactly 12 hours long and night will be exactly 12 hours long. After today in the Northern Hemisphere, the days will be longer than the nights. Officially spring arrives today at 9:58 PM Greenwich Mean Time (5:58 PM Eastern Daylight Time where we live).
In reality, all of this is an exaggeration of the real situation.Don’t expect a balmy spring day if you live in Michigan (as we do) or other northern areas. Ice and snow have to melt, and the land has to warm up. Nevertheless, the equinox does remind us of Earth’s design and how many variables control our existence on this planet. What does happen on this day is that the Sun will be directly overhead at noon at the equator.
During the northern winter, Earth’s tilt has caused the Sun to be overhead south of the Equator. As the Earth moves around the Sun, the Sun’s location relative our planet will drift north until June. When the summer solstice occurs on June 21, the Sun will be overhead at 23 degrees north latitude. The more direct sunlight not only warms the Northern Hemisphere, but it avoids overheating the Southern Hemisphere.
If Earth did not have a 23-degree axis tilt, the Sun would beat down on the equator from directly overhead all year long. The Equator would become so hot that nothing could live there. The northern and southern latitudes would both freeze. Wind belts created by air rising violently at the equator would be hurricane force 24/7. We see that happening on planets in the solar system that do not have an axis tilt.
Ancient people knew that the position of the Sun changes throughout the year. They used elaborate but primitive observatories to determine the time to plant and harvest based on the Sun’s position. Unfortunately, this led many cultures to worship the Sun. Nowhere does the Bible encourage or condone the worship of any celestial bodies. The Bible recognizes the seasons and the role of the Sun as designed by God for human existence. (See Genesis 1:14-15).
The ancient psalmist David said it (Psalms 8:4) and the writer of Hebrews quoted it (Hebrews 2:6), “What is man that you keep him in mind or the son of man that you look after him?” The equinox is a good time to be reminded of God’s provisions for us and thankfully worship the Creator, not the creation.
Yesterday we mentioned that the Sun was at the exact angle to illuminate the Moon’s Jura Mountain Range. The effect is sometimes called the Golden Handle of the Moon because it resembles a small handle on the side. Since the sky was clear here in southwest Michigan last night, I took a picture of it. The tiny “handle” that you see is a semi-circular ridge surrounding a flat plain called the Sinus Iridium (Latin for the Bay of Rainbows). Sinus Iridium is actually an impact crater which has filled with lava, and the “mountains” that the Sun is illuminating is the edge of the crater.
In the NASA photo, you can see wave ripples on the surface as the lava flowed into the basin of the crater and hardened.
On our Does God Exist? educational tours of the Canyonlands we always visit Meteor Crater in Arizona. It is perhaps the best-preserved impact crater on Earth. At three-quarters of a mile (1.2 km) across, it is awe-inspiring to see. By comparison, the Sinus Iridium crater is 150 miles (240 km) across. You can also see several smaller impact craters that were formed after the lava flow.
As you examine the surface of the Moon, you will see that it is covered with impact craters caused by meteor and asteroid collisions. Earth has been bombarded with asteroids in the past. There is evidence of a large (93 mile, 150 km) impact crater called the Chicxulub Crater near what is today the Yucatan Peninsula.
Since Earth is a bigger target for impacts, why is Earth’s surface not pockmarked with craters like the Moon’ surface? Scientists have found evidence of about 190 impact craters on Earth. Most of them were early in Earth’s history, and erosion, plate tectonics, and other forces have hidden them from view. More importantly, we are protected from many of the impacts by our atmosphere. The heat from friction as a meteor enters the atmosphere at high speeds usually, but not always, causes them to burn up before they touch the ground. The more we see of God’s creation, the more we see His wisdom and power.

If the sky is clear tonight (March 16, 2019), you will have an opportunity to observe an interesting phenomenon known as the Moon’s Golden Handle.
The Sun’s light will strike a mountainous area of the Moon at a shallow angle. The Moon will be in what is known as the waxing gibbous phase. Waxing means that more of it is becoming visible as sunlight increasingly illuminates the surface. Gibbous means that it is not yet a full moon, but it is more than a half moon. At this exact angle, the sunlight will illuminate the Jura Mountain Range, and the mountains will appear as an arc on the upper left side of the Moon’s visible surface. The arc resembles a tiny handle on the side of the Moon, so it has been called the Moon’s Golden Handle.
Galileo (1564-1642) observed this phenomenon as he looked through an early telescope. You can see it with a pair of binoculars. If you have a small telescope, you can get an even better view. The angle of the light gives a unique opportunity to get an idea of what the surface of the Moon is like. Not only does the Moon have mountains, but it has lava flows and numerous craters from bombardment by meteors.
The fact that we can predict when lunar eclipses will take place and when phases of the Moon will occur shows how much precision God has built into His creation of the cosmos. We know when the Moon’s Golden Handle will be visible because we can depend on that precision as we depend on God. “The heavens declare the glory of God and the firmament shows His handiwork” (Psalms 19:1).
Many leaders in the United States, as well as other countries of the world, seem to have a view of global warming that contradicts the evidence and good scientific data. More amazing is that many scientists also take positions on global warming that don’t fit the evidence. Science News (March 2, 2019) published an article (page 6) about various theories of how melting ice could affect eustatic sea level rise.
One estimate is that sea levels could rise by 2.1 meters (over six feet) by 2100. Another research report says that sea levels could rise by four meters by 2200. Both of these estimates are based on the melting of ice cliffs in Antarctica. Imagine the result of an eight-foot rise of sea level on Miami or New Orleans or Venice?
The problem with the scientific data, as spelled out in the Science News article, is that the physics of ice cliff collapse is very poorly studied. Another problem is that much of the ice that has been proposed as being likely to melt is floating. If the ice is floating, it has displaced as much water as it weighs or it wouldn’t be floating. This is an old physics law that says “any object that is placed in a fluid is buoyed up by a force equal to the weight of the fluid displaced.” If the iceberg somehow evaporated instead of melting, the sea level would go down. If it just melted, the mass is still there, and there would be no sea level rise.
Scientists are hotly debating the predictions of eustatic sea level rise. The question is not whether we are experiencing climate change with an increase in worldwide average temperatures. We are. The question is what that temperature rise will do. The design of the amazing physics of ice and water may seem simple, but it is highly complex on a global scale. We see evidence of God’s design of Earth to support human civilization. Stay tuned for more data as research continues.
