June 20, 2021, was the summer solstice in the Northern Hemisphere and the longest period of sunlight of any day this year. Now that we have passed the summer solstice, the days are getting shorter. That raises the question of why the summer solstice is not the hottest day of the year since the Sun is up for the longest time. The answer to that is simple. It’s because every day until September’s fall equinox has more hours of sunlight than darkness, and there is a heat lag. It takes a long time for Earth to heat up after winter, so normally the hottest day is well after the summer solstice.
A more important point is why the summer solstice happens and how it is critical to life on planet Earth. The cause of the solstice and the equinox is that Earth is tilted on its axis by 23 ½ degrees. As it orbits the Sun, that tilt causes every point on Earth to experience different amounts of Sun each day and controls the angles at which the Sun’s rays hit Earth’s surface. On the equinox, the Sun is directly overhead at the equator. At noon, the Sun would shine down to the bottom of a well on the equator. Every other latitude on the planet would have the Sun’s rays hitting Earth’s surface at an angle that is not perpendicular.
As Earth revolves around the Sun, it is essentially a giant gyroscope with the poles always pointed in the same direction. It isn’t until the solstices that the Sun would shine right down a well at its northern or southern position, and that happens to be 23 ½ degrees north or south latitude. So why is that important?
If Earth did not have the axis tilt, we would not have the summer solstice in the Northern Hemisphere. The Sun would always be directly overhead at the equator all the time. Land near the equator would be so hot that life could not exist there. Areas to the north and south would be extremely cold. The temperature differences would create extreme winds, making life difficult. When scientists ran computer simulations, they found that 23 ½ degrees is ideal for minimizing overheating and cooling.
Earth also has a heat sink designed into it—the oceans. Most of the southern hemisphere is covered with water, while the northern hemisphere has more land. Since Earth’s orbit is an ellipse rather than a perfect circle, the southern oceans absorb much of the heat when Earth is closest to the Sun. It just happens that Earth is closest to the Sun when the Southern Hemisphere is in the summer season. It seems like it was planned that way.
We are thankful that we had the summer solstice in the Northern Hemisphere. The Earth’s tilt, spin, and distribution of land and water are not accidents. They are designed features of our planet that speak of God’s wisdom and planning in the creation.
People who promote the theory of evolution generally ignore historical events that would be Inconsistent with neo-Darwinism. Darwinism depends on an acceptance of uniformitarianism, the belief that no process has ever operated in the past that is not going on today. Previously, we have talked about past asteroid collisions with the Earth, which is an example of a process that isn’t shaping our planet and life on Earth today. Researchers in New Zealand have released a new study of changes in Earth’s magnetic field. That process, which radically altered the Earth some 42,000 years ago, is not a factor in understanding modern geologic processes.
In a magnetic reversal, changes in Earth’s magnetic field cause the north and south magnetic poles to switch. Researchers at the University of New South Wales have shown that this transition took nearly 800 years to complete, and during that time, the planet would have had no magnetic field.
The lack of a magnetic field would have been a major catastrophe which is not going on today. Our magnetic field acts as a shield against high-energy charged particles coming primarily from the Sun. Without that shield, there would have been severe environmental threats to life on Earth. Their study suggests that tropical rain belts shifted, glaciers stretched across North America, and a severe drought hit Australia. The effects of the increased radiation on living things would have a strong genetic impact.
The researchers suggest that humans living during Earth’s magnetic field changes would have to retreat to caves for shelter from the radiation and the harsh weather conditions caused by the magnetic reversal. Chris Turney, one of the authors of the study, said that any humans living at that time would have seen what was happening as “the end of days.”
The notion that Earth has been a quiet incubator for life over a very long time is inconsistent with the evidence. Losing our magnetic field would be the start of a domino effect of changes, all of which would harm life. Our magnetic field is slowly decreasing now, but this data, and other studies like it, suggest that magnetic reversals are prolonged events lasting 800 years.
The Bible makes it clear that catastrophic events are rare in Earth’s human history. Noah’s flood, the death and resurrection of Christ, and His second coming seem to be the most apparent biblical events that are catastrophic. Our planet’s stability is a part of God’s design, and without it, we would not be here. But history is punctuated with events on the Earth that are not uniformitarian such as changes in Earth’s magnetic field. Those changes have altered our planet to make it hospitable for human life. They also make it impossible to have a faith that says chance and time can account for all life we see on planet Earth.
Frequently, science clarifies biblical statements, but no scientific facts have ever contradicted the biblical account. Contradiction would be impossible since the God who created and made Earth also gave us the Bible. A recent example of their agreement is demonstrated by an Earth rock found on the moon.
The Bible uses an economy of language because an exhaustive explanation would have confused people reading it 500 years ago. The simple clarity of the Genesis account contrasts with literally thousands of scientific papers and books giving details of the biblical statement, “In the beginning, God created the heaven and the earth” (Genesis 1:1). Another interesting passage in Genesis is the second verse, which indicates a change in the Earth. The most accurate translation of verse two is, “And the earth became without form and void, and darkness was upon the face of the deep.”
The National Aeronautics and Space Administration’s daily blog announced the results of an internal X-ray scan of lunar sample 14321.Alan Shepard picked up the 14321 sample during the Apollo 14 lunar mission. It shows chemistry identical to Earth’s material and completely different from lunar material. NASA says that the sample is older than Earth’s surface materials and indicates a dramatic event.
Various things could have caused this change in Earth’s surface. A massive volcanic event like the one that produced Mount Mazama (now called Crater Lake in Oregon) could blow material into space. Such volcanic eruptions produced lava, which enriched the soils allowing plant growth to be prolific in the ancient Earth. Another possibility is that a celestial object like an asteroid or comet hit our planet and blasted material into space, with some of it landing on the moon. Either way, an Earth rock found on the moon fits the biblical narrative.
The scientific information simply demonstrates the accuracy of the brief biblical account. When religious leaders challenged Galileo’s science, he wrote in a letter, “The Bible shows the way to go to heaven, not the way the heavens go.” Science and the Bible are symbiotic – each beneficial to the other and in agreement with each other. However, they explain different aspects of human concern.
For a hundred years, scientists looked for the answer to a perplexing question. In 1859 British astronomers observed what we now call a solar flare. The next day there was a disturbance of Earth’s magnetic field called a geomagnetic storm. Scientists were puzzled over what was happening. After a century of study, the answer came down to solar wind and Earth’s magnetic shield.
In 1958, American astrophysicist Eugene Parker described the phenomenon and named it “solar wind.” The solar wind consists of charged particles ejected from the corona (extended outer layer) of the Sun and traveling at high speed into space. This material is plasma, a mixture of negative electrons and positive ions. Since electric charges and magnetic fields interact, the planet’s magnetic field steers the solar wind away from the planet’s surface when it reaches Earth. Because Earth’s magnetic field originates from the North and South poles, we see the interaction in those regions as beautiful auroras, the Northern and Southern lights.
What if Earth did not have a magnetic field? The solar wind would reach Earth’s surface and significantly damage living cells, bringing an end to life. Our neighboring planets Venus, Mars, and Mercury have little or no magnetic field and therefore are bombarded by the solar wind.
Why is our planet different? Why do we have the protection of a magnetic field? The motion of the molten iron in Earth’s core produces the magnetic field. Why does Earth have a molten iron core? Heat generated by the decay of the radioactive elements uranium and thorium keeps the iron core from becoming solid.
The bottom line is this: Hidden inside our planet is a magnetic-field generator powered by unseen radioactivity that gives us an invisible magnetic shield protecting us from invisible destructive particles coming from the Sun. This same process also gives us beautiful auroras we enjoy watching. The solar wind and Earth’s magnetic shield give us one more example of the beautiful design of the planet we call home. Did this all happen by accident? We don’t think so.
The media often overlook how many things have to be “right” for life to exist on a planet. Planetary atmospheric pressure is one factor.
By “life,” we mean the standard textbook definition of organisms that can move, breathe, respond to outside stimuli, and reproduce. The problem is that many conditions make other terrestrial planets (planets with hard surfaces) unlikely to harbor life. Life is even less likely on Jovian planets that are primarily gaseous. You can postulate balloon-like living organisms in Jupiter or Saturn’s atmosphere, but radiation and electrical problems make that unlikely as well.
Planetary atmospheric pressure depends on the weight of the gases above a planet’s surface. The air pressure on Earth’s surface is 14.696 pounds per square inch a sea level. That pressure allows water to exist as a liquid, and it will enable various gases to dissolve in the water. We all know what happens when you shake a bottle of carbonated beverage and then quickly remove the cap. The sudden drop in pressure causes an explosion as the dissolved carbon dioxide escapes from the liquid. For organisms to absorb oxygen dissolved in water, which fish do, the atmospheric pressure must be high enough for the oxygen to dissolve. The atmospheric pressure on the surface of Mars is .01 of the pressure on Earth. That means water on Mars would contain no oxygen or dissolved gases.
There has been discussion about finding water on the Moon or Mercury, but those atmospheric pressures are considerably lower than those on Mars. That means water would not be in a liquid state. On the other end of the pressure spectrum is Venus, where atmospheric pressure 92 times greater than on Earth. At that pressure, toxic gases would be dissolved in any water that existed on the planet.
Planetary atmospheric pressure is just one more variable that must be carefully and precisely chosen when constructing an environment that will support and sustain life. The creation is far more complicated than most of us realize. As we learn more, we must stand in awe of the God who created our planet.
The power released by the Sun every second is equal to ninety-six billion megatons. One megaton is the explosive power of one million tons of TNT. That is a mighty powerful Sun.
All of that energy is released by immense numbers of tiny hydrogen atoms fusing into helium atoms at a rate of four hydrogens to make each helium. The process requires incredibly high temperatures to get it started. After the fusion, the helium atom has less mass than the total of the four hydrogen atoms by 0.7 percent, indicating that a tiny amount of mass has been converted into energy. The energy released provides heat to keep the process going and the energy that powers our solar system and our planet.
Humans duplicated the process of atomic fusion in 1952 with the first hydrogen bomb. It was repeated in 1954 with a more powerful explosion equal to fifteen megatons. To obtain the high temperature required, scientists had to use an atomic (fission) bomb to get the fusion process going.
The hydrogen bomb is the most power that humans have ever been able to release, and we hope it’s the most that will ever be released on Earth. Compare that one-time 15 megatons to the ninety-six billion megatons per second released in the Sun. Then compare our mighty powerful Sun to many other stars which dwarf the Sun’s power. The stars Rigel and Deneb each release the energy of 200,000 Suns, but even they are not the largest power generators in the universe.
All of this is already far beyond my ability to comprehend. I can only say, “Tell everyone about God’s power…his strength is mighty in the heavens” (Psalms 68:34 NLT).
I have always been fascinated that sometimes Jesus wanted to be by Himself, away from the crowds and even His disciples. He was God in the flesh, but He needed to escape the human noise. There are times in my life when I just want silence. There is an island on Saganaga Lake in Ontario where my family built a cabin. I have always loved going there because all you can hear is the wind and the waves.
The December 2020 issue of Scientific American carried an interesting article about human noise. Amazingly, human noise produces seismic vibrations that can be measured by instruments as deep as 400 meters below Earth’s surface. Scientific studies of seismic vibrations in 172 locations worldwide showed that when the COVID-19 pandemic hit, the volume of human noise fell by 50% in some places. In rural areas, the noise level depression was even lower. Before the COVID-19 pandemic, the human noise level fell on Sundays, but it has declined and stayed depressed since the pandemic began. When you add up the noise of trains, buses, planes, and cars, the noise level is very high. It is not enough to cause earthquakes, but it does have other effects.
The big question for science to answer is, What effect noise has on not just humans, but on the world as a whole? Are animals affected by the noise levels we create? How does noise affect a child’s ability to concentrate? Do noise levels affect the concentration and productivity of workers in a factory? Are some forms of mental illness affected or even caused by our exposure to noise?
Noise has a role in the Old Testament. In Joshua 6, we see that noise played a role in the fall of the walls of Jericho. Many passages talk about various noises in a variety of situations. Some passages emphasize the need for quiet. Psalms 46:10 says, “Be still and know that I am God …” After the noise of wind, earthquake, and fire, God spoke to Elijah in a soft whisper (1 Kings 19:11-13). In the New Testament, Paul commends the Christians who study “to be quiet, and to do your own business (1 Thessalonians 4:11).”
All of us need to escape the human noise of this world and have a quiet time to focus on God and quietly glorify Him.
Over the years, this ministry has taken groups of people on what we call the “Canyonlands Tour” more than 30 times. A highlight of that trip is visiting the Grand Canyon. Looking into the Canyon, we see the various layers of rock, with each layer having a different set of properties. The study of Grand Canyon stratigraphy shows God’s design that allows us to live on this planet.
The materials in the layers (strata) of Earth all come from the molten material that made up the planet at its origin. Molten material solidified into granite. The red orthoclase material weathered out of the granite first, producing clay. Feldspars containing vital elements like iron, magnesium, calcium, and potassium came out of the granite, leaving quartz behind. The quartz became sand, and the other elements became soil, limestone, and all the other materials we see in the strata today.
As we stand on the edge of the Canyon, we can see the alternating layers of the Grand Canyon stratigraphy. We see sandstone (made of quartz), shale (made from mud), conglomerate (made from gravel), and limestone (a chemically precipitated rock made slowly in an area of quiet water). Deep within the canyon, we see layers tilted at an angle, indicating catastrophic geologic activity. Below that, we see rocks that have been altered by heat and pressure (metamorphic rocks). At the very bottom, we see the original volcanic granite from which all of this was formed.
We gaze in awe at the history of Earth before our eyes, and we marvel at God’s wisdom in design to prepare this incredible planet on which we live.
In the book of Job, God asks the character Job, “Can you loose the cords of Orion? Can you bring forth the constellations in their seasons?” What are the cords of Orion?
Since ancient times, people imagined that the asterism in the Orion constellation resembles a hunter holding a sword. The sword appears to consist of three stars. However, if you look closely, you can see that the central star is a little “fuzzy.” With a telescope, you can see that it’s not a star, but a nebula.
The picture of the Orion Nebula was taken by NASA’s Hubble space telescope. Nebulae are star factories, where clouds of dust and gas are collapsing to form stars. At “only” 1344 light-years from Earth, Orion is our closest star factory. Astronomers have observed about 700 stars in various stages of formation in the Orion Nebula.
As we look at the cords of Orion, here is something to consider. God, who is outside of time, created a star factory in time, which then generated a star we call the Sun. Then He provided a home for us on the third planet from that star where we can look up and see star factories, like the Orion Nebula, at work.
The fact is that a Japanese robotic satellite that has been orbiting Venus since 2015 records data in the ultraviolet part of the spectrum. The satellite has detected spectra for the chemical phosphine (PH3). Phosphine is a flammable, toxic gas made of one phosphorous atom attached to three hydrogen atoms. It is difficult to make in a typical chemistry lab. Biologists know that there are microbes that can make phosphine. Finding the chemical in the upper clouds of Venus, where the temperatures are low enough for the gas to exist, raised some questions about whether microbes could have produced it.
It is possible that the phosphine could have been produced by conditions on Venus that are not available on Earth. Such conditions could be very low pressures, long term effects of ultraviolet light, and long periods of time. The environment of Venus is highly toxic, even to microbes, so microbe production is unlikely. Scientists have found many of the chemicals essential to life or possibly produced by living organisms on several moons in the solar system. The creation process produces chemicals that can be associated with life, including water. The environmental parameters of all of these places are so extreme that no astronomer expects to see an alien walking around.
The Bible doesn’t say that Earth is the only place where life exists, and it may be that God has created life elsewhere. As humans leave our planet searching for chemicals and materials to meet the 21st century’s needs, we may find a storehouse of essential materials, both metallic and biological. Did science find life on Venus? No. This newest media hype does not tell us anything we didn’t already know, but the discovery is interesting.
