Shortest Day on Record?

If you’re thinking that you didn’t accomplish much yesterday, August 5, 2025, it might be because the day was shorter than usual. I don’t mean that the daylight hours were shorter. Earth’s solar day was shorter than the typical 24 hours, which equals 86,400 seconds. You probably didn’t notice because the day was only 1.25 milliseconds shorter. Blaming the shortest day won’t help—you’ll need to find some other reason for not achieving more.

Earth’s rotation speed had been gradually slowing down, but for some reason it started speeding up in recent years, making the days shorter. Official and precise records of solar day lengths since 1973 show that they were getting longer. Earth’s gravity creates friction against the Moon, causing it to drift farther away and slowing Earth’s rotation. A slower rotation results in longer days.

The Moon’s position relative to Earth’s equator creates tidal forces that very subtly influence Earth’s rotation rate. Scientists speculate that the slower rotation of Earth’s liquid core might cause the outer layers of the planet to spin faster, but that remains only speculation.

We can’t really say that yesterday was the shortest day because July 5, 2024, was 1.66 milliseconds shorter than the usual 24 hours. Don’t worry about any noticeable change in the length of days. God has given us an incredibly stable planet on which to live. Many finely tuned factors make life on Earth and our existence possible, and it could not have been accidental. This remarkable planet is further evidence that God exists.

Radical Sea Level Changes

Scientific American magazine reported that if the entire Greenland ice sheet melted, global sea levels would rise by 24 feet. The article clarified by saying, “The sheet won’t melt all at once, of course…” What articles like this fail to convey is that Earth has experienced radical sea level changes throughout both geologic and human history.

Geologic history shows marine deposits in places you wouldn’t expect. When I taught earth science, I took my classes to Thornton Reef on the south edge of Chicago, Illinois. I am told that the gravel pit now occupying the reef is the largest in the United States. On one trip there, a student found the tube of a cephalopod, an ancient giant octopus-like creature. Clam shells, snail shells, and brachiopods filled buckets that my students took home. This reef is similar to modern ocean reefs, except it winds through the south side of Chicago with a major interstate highway running right through it.

Other examples of historic radical sea level changes are abundant. Oolitic limestone in southern Indiana consists of tiny ocean creatures called oolites. The limestone in the Grand Canyon contains marine deposits. On the other end of the scale, canyons are cut into continental shelves along the U.S. East Coast of the United States. Those canyons were cut when the shelf was out of water. Scuba divers have reported signs of ancient human-made structures and fire pits in those canyons.

Was the Red Sea at the same level when Moses led the Israelites across? Are people searching for Egyptian armor and chariot remains in the wrong spots? The “Sea of Reeds” was likely dry land at that time, so efforts there are probably doomed to fail. We still have much to learn about climate history, radical sea level changes, and ancient peoples. As our technology improves, discoveries will increase, and we look forward to uncovering more evidence of Earth’s history.

Dealing With Disasters

One of the challenges that we all face is dealing with disasters such as tornadoes, hurricanes, and floods. Skeptics claim that if a God exists, He wouldn’t allow these terrible natural disasters to take place. That claim displays a combination of scientific and theological ignorance.

Tornadoes result when hot air is trapped under a layer of cold air. Warm air rises, but if the cold air above it is dense enough, the warm surface air will become even warmer. Eventually, the hot air will rise through the cold layer. Hang glider pilots and soaring birds look for these vertical updrafts. When the ground is covered with vegetation, there is never enough heat to trigger a strong upward air movement. However, when thousands of acres of land are plowed up or paved over, the surface air becomes hotter and creates stronger vertical movement. Earth’s rotation spins these upward air movements, creating a tornado.

Areas around 30 degrees north and south latitude are usually deserts. The states of Florida, Georgia, Mississippi, and Alabama are at or near 30 degrees north latitude. Hurricanes pick up massive amounts of water from the ocean and dump it on the land. Without hurricanes, there would be a water shortage in many places. In the past, storm surges were not a problem because the coastal areas were lined with mangroves and other plants on the barrier islands and along the mainland coast. Today, that protection has been stripped away and replaced with hotels, roads, parking lots, and beach-front homes. The result is that we are dealing with disasters.

God told humans to take care of the Earth, but greed, selfishness, and ignorance have often caused disasters. The more we learn about the creation, the more we understand that God designed it to work well, but humans have brought much pain and suffering on ourselves by misusing God’s gift. We must work together and avoid repeating past mistakes, or we will continually be dealing with disasters.

Why We Care About Entropy

As a high school physics teacher, I frequently found myself challenged to keep my students interested. Some subjects were easy, but others were challenging, and the kids became bored very quickly. An example of the latter was a unit on the laws of thermodynamics. The second law, also known as the entropy law, states that a closed system tends to become increasingly disordered over time. Entropy is a statistical measure of disorder. During that unit of study, I once had a student who said, “Who cares?” There are good reasons why we care about entropy.

My response is that entropy is a design feature of the cosmos that produces black holes, but it also allows us to breathe and have engines in our cars. As a public-school teacher, I could not bring my religious views into the classroom, but it also disproves one of the atheist arguments against the existence of God.

When we say that God has always existed and He created the cosmos, atheists ask, “Then who created God?” They suggest it is easier to believe that matter has always existed. Why we care about entropy is that it shows that matter and the cosmos have not always existed.

Every reaction in the physical world reduces the amount of energy available to do work. The total energy in the cosmos available to do work is constantly decreasing, eventually becoming zero, and entropy will be maximum. That means the cosmos could not be eternal, and it must have had a beginning. There must be a cause for that beginning, and that cause is God.

The Creation of Matter from Nothing

In high school, I enjoyed science and decided that I wanted to be a scientist of some kind. I entered Indiana University and enrolled in an astronomy course at the feet of one of the great astronomers of the day. In that course, we studied the problem of origins — the creation of matter from nothing. As we discussed this subject, we went into various theories that had been proposed.

When we got to the conclusion of the discussion, I asked the professor which of the theories was the most acceptable one that satisfactorily explains the creation of matter from nothing. He leaned over the desk, looked me straight in the eye, and said, “Young man, you need to learn to ask intelligent questions.”

I did not appreciate the professor’s response, so I said, “Well, what do you mean?” He said, “This is not a question that a scientist tries to answer. This is a question for the philosopher or theologian, but this is not something that falls into the realm of science.” In today’s discussions of black holes and parallel universes, things have not changed. The fundamental question of the creation of matter/energy from absolutely nothing is not an area that can be scientifically explored.

I had always felt that science could ultimately answer all the questions humans have. I believed there was no challenge that science could not eventually resolve. Yet this learned man, an expert in his field, said that this was an area that the scientist should not even try to answer. It was totally beyond the capacity of science to explain and explore.

That was more than 50 years ago. Today there are even more questions science can’t answer, and one of the remaining unanswered questions involves the creation of matter from nothing.

Confidence in Astronomical Observations

Some people have asked how we can know that astronomers’ statements about the evolution and demise of stars are factual. This question is usually asked by those in religious denominations that demand a young Earth, which means a young cosmos. Even though the time factors are much longer than human existence, we can have confidence in astronomical observations.

Although humanity has not been around long enough to observe the complete life of a star, we have seen intermediate steps in star evolution. Astronomers plot the luminosity (brightness) of stars against their surface temperature (or color/spectral type) with graphs called the Hertzsprung-Russell (H-R) diagram. It’s a powerful tool for classifying stars, studying their evolution, and understanding their properties. An example is the Crab Nebula.

In 1054, astronomers saw a star explode. The debris pattern of the explosion resembles a crab, so astronomers call it the Crab Nebula. Almost a millennium later, measurements show that the nebula is roughly 10 light years in diameter and is expanding at 1,500 kilometers per second. Observations of the Crab Nebula by the Hubble telescope in 2005 and the Webb telescope in 2023 show steps in the life of a star. Observations of other stars provide more information about a star’s lifetime, giving us confidence in astronomical observations.

Even though I didn’t see the launch, if I see a rocket climbing higher in the sky with every passing second, I know it was launched. I can even compute the launch time. When a car comes to a stop, leaving tire tracks, I know the car was going fast when someone applied the brakes. Every day, we understand evidence of a process without seeing it from start to finish. Astronomers come to understand the life history of stars in the same way.

As we have pointed out before, the Bible does not tell us the age of the cosmos or Earth. We can have confidence in astronomical observations. Young-earth theology is not only in opposition to the evidence but is also inconsistent with the biblical account.

The Mantis Shrimp’s Design

Naturalistic evolution cannot explain many things in nature. For example, why do various birds display colors that offer no purpose and may make them vulnerable to predators? We see one of the most interesting examples that doesn’t fit blind mechanistic chance in the mantis shrimp’s design feature that can exert a blow 1000 times its body weight.

The mantis shrimp uses a club-like feature to strike its prey with a force so extreme that it creates imploding bubbles that increase the force. The question is how the design of the mantis shrimp’s club-like feature doesn’t harm the shrimp. Dr Horacio Espinosa at Northwestern University in Evanston, Illinois, has published a study explaining the mantis shrimp’s design.

Mantis shrimps have layers of mineral-hardened chitin arranged in bundles, with each layer rotated slightly with respect to the layers above and below. You might compare it to a stack of papers that have been twisted, creating a helix-like corkscrewing shape. This arrangement dissipates the strike’s energy and prevents shear waves from damaging the soft tissue of the shrimp.

Engineers are trying to copy this design to increase the toughness of airplane wings and wind turbine blades. They are sure to find more uses in future high-performance materials. We have previously highlighted the mantis shrimp’s design features, including its club, eyes, and visual system. The shrimp’s protective layer is one more example of a design scientists discovered in the natural world that can aid the design of objects beneficial to humans. God thought of these features first, and they are the product of intelligence – not mechanistic, opportunistic chance.

Soil Moisture and Water Shortages

Living on a river that feeds Lake Michigan, we tend to ignore messages of water shortages. There is some irrigation in our area, but nothing like what we see in other regions of the world. Recent studies of global soil moisture show a very different picture.

Drought events at various global locations have caused the loss of 1.614 gigatons of water between 2000 and 2002. (One gigaton is one billion tons.) In the United States, irrigation has been highly contested as rivers in Nebraska and Colorado cannot supply the water needed to grow wheat and other grain crops. Drawing from the water table has caused it to drop over 10 feet in recent years.

Studies at the University of Texas and Seoul National University show that the problem of water shortages will cause more hunger and human suffering if we don’t do something to stop the soil moisture loss. The solution to water shortages is available.

There was no way to recover water lost to the oceans in the Old Testament days, but now there is. We can use nuclear energy and various processes to desalinate seawater. Removing the salt from seawater provides the salt humans need while producing fresh water for irrigation and replacing soil moisture.

God has provided humans with the water we need. In ancient times, humans lived by bodies of fresh water. With the expanding human population, not everyone could live on the shores of lakes or along rivers, so water had to be moved from places of plenty to places of drought. The Romans did this with aqueducts stretching for miles. In the western United States, we can allow rainfall and mountain ice melt to replace soil moisture while supplementing the need for water in cities by the ocean, like Los Angeles, using desalination.

The teachings of Jesus were ones of peace and concern for others. Water shortages have fueled greed and rivalry in areas of our planet. We need to use the nuclear energy God has given us to desalinate water rather than as a tool of war.

Martian Surface Is Inhospitable for Life

As we have reported on this website, the Martian surface is inhospitable for life. New discoveries show that no life exists there now, and the chemistry of material reached by drilling into Mars’ surface does not show that life has ever existed on that planet.

The media suggest that life on Earth is not exceptional while the scientific data shows that our planet is the only place in the solar system where life can exist. Skeptics would like to find life beyond Earth because they feel it would show that God did not create and design Earth for the existence of humans. Unfortunately, the media often cherry-picks previous data while ignoring more recent findings.

In a USA Today article, Erik Lagatta reported that the Curiosity rover detected some strange spheres in the past. At that time the media claimed that biological processes could have produced these spheres. Further tests showed they were mineral deposits that had nothing to do with life. They were probably formed by groundwater circulating through rock pores.

NASA is interested in the rocks on Mars because they can tell us much about the planet’s geological history. Taking a fresh look at a previously collected sample, NASA scientists found fragments of fatty acids, the largest organic molecules so far discovered on Mars. However, fatty acids do not necessarily indicate life because they can be generated by chemical reactions related to geological processes.

The Martian surface is inhospitable for life, but as we have pointed out before, whether life exists elsewhere in the cosmos is not an issue for the biblical account of life on Earth. If there is life elsewhere, God created it. However, we will probably never know because the distances to other galaxies are so vast that we can never travel there to find out.

First Peter 3:15 tells us to be ready to “give an answer to anyone who asks about the hope that we have.” There is vast evidence for the existence of God, and it is essential to know why we believe what we believe so we can answer our children’s questions.

Hadley Cells and God’s Design

One of planet Earth’s many unique design features is the atmosphere’s circulation pattern, allowing advanced life to exist on our planet. This pattern was first noticed in 1735 when George Hadley was working with the motions of wind recorded by scientists. Realizing that wind currents were not just accidental, he originated the idea of what we call Hadley cells. We know today that the circulation of the atmosphere is much more critical and complex than anyone understood in Hadley’s day.

A feature designed into Earth’s weather pattern is how the insolation moves daily. Insolation is the amount of solar radiation that reaches the surface of a planet. Of the other planets in our solar system, only Mars has a tilt, which spreads the insolation from one latitude to the next, but Mars does not have enough atmosphere for this to be a significant factor. The other planets don’t change their tilt, so the Sun’s radiation is constantly over one latitude. The temperatures at that latitude climb very high, and everywhere else is unbelievably cold.

On Earth, the Sun’s energy gradually changes daily, moving to 20 degrees north or south latitude and striking at the Earth’s equator only two times a year. The Sun is over the equator at the equinoxes on about March 20 and September 22, and the day and night length is the same. Around June 21, the Sun is as far north as it gets, and around December 22, it reaches its southernmost point.

In the Hadley cells, air rises in tropical zones, where it drops its moisture as it cools. At 30 degrees latitude, the cooler air sinks and has very little moisture. Virtually all of Earth’s major deserts are around 30 degrees latitude north and south. In the western United States, we find the Mohave Desert, but the eastern U.S. does not have a desert even though it is at 30 degrees. Hurricanes and the Atlantic Ocean bring a large amount of water to states located at 30 degrees latitude in the eastern U.S. So many things make advanced life possible on this planet that trying to attribute all of them to chance requires far more faith than believing that God designed and created the weather on Earth so you and I can exist.
