In a few days, a total solar eclipse will cross the full width of the United States, and you can give credit for that to the just right moon.
We have looked at the “how” and “why” of total solar eclipses. We have considered what value total solar eclipses have. We have seen that a total eclipse helped to confirm a very important scientific principle. Also, we pointed out that solar eclipses happen only at the time of the new moon when the Moon is between the Earth and the Sun.
A new moon occurs about every 29 days, so why doesn’t an eclipse happen at each new moon? That’s because the plane of the orbit of the Moon around the Earth is about five degrees off from the orbital path of the Earth around the Sun. Because of that difference, a solar eclipse happens only when the Moon crosses the path of Earth’s orbit around the Sun (called the ecliptic). A TOTAL solar eclipse happens only when the Sun and Moon are exactly aligned.
What would happen if the orbit of the Moon were on the same plane as the ecliptic? At every new moon we would have a total solar eclipse, and at every full moon, we would have a total lunar eclipse. So the Sun would go dark in the daytime somewhere on Earth every month, and the full Moon would also go dark monthly. The influence of the Sun’s gravity on the lunar orbit might cause more serious problems.
Here is an interesting story of how a solar eclipse helped to confirm a scientific theory and demonstrated the value of a total solar eclipse.
Yesterday, we pointed out that it’s more than a “marvelous coincidence” that the Moon can exactly block our view of the much larger Sun. It’s an evidence of design. When the Moon hides the Sun’s photosphere, scientists can study the chromosphere and the corona to learn more about the Sun and how it affects life on Earth.
In 1687 Isaac Newton presented his universal law of gravitation answering many questions about gravity. One question that remained unanswered was how gravity can act through empty space.
In 1916 Albert Einstein presented his theory of general relativity in which he proposed that mass produces gravity by warping space. Planets orbit the Sun because the mass of the Sun and the planets causes space to be curved. The theory suggested that light would also follow a curved path because of this warping. Einstein calculated how much light would bend near a massive object and proposed that light from distant stars would be bent when it passes by the Sun.
Einstein’s idea seemed hard to believe, but there was no way to disprove it since the bright Sun hides any starlight passing near it. You can’t see the stars during the day.
Then in 1919, British astrophysicist Arthur Eddington made some measurements during a total solar eclipse. While the Moon blocked the Sun’s photosphere, Eddington made precise measurements of the apparent position of stars that were visible near the Sun. Comparing those measurements with the positions of the same stars at night, he confirmed that Einstein was correct. The light was bent as it passed by the Sun.
Yesterday we talked about the upcoming total solar eclipse and the fact that the Moon can completely hide the Sun from view. That seems very strange since the Sun is about 390 times larger than the Moon. By a “marvelous coincidence” the Sun is 390 times farther away than the Moon. Since the Sun is 390 times farther away, it appears to be 390 times smaller. For that reason, when we see the Moon and the Sun in the sky, they appear to be the same size.
The Moon can exactly cover the Sun’s disc which we call the photosphere. At the same time, in a total eclipse, we can see the chromosphere, which is the very bright atmosphere surrounding the Sun. We can also see what is called the corona–jets of hot gas which follow the lines of the Sun’s magnetic field. Under normal circumstances, the chromosphere and corona are invisible because of the glare from the photosphere.
Scientists have learned much about the Sun by studying what we can see only during total solar eclipses. Only during a total solar eclipse can scientists study the “solar wind” which sends out streams of particles called coronal mass ejections (CME). CMEs can travel all the way to Earth and knock out communication satellites or terrestrial power grids. Just as scientists work to predict weather on Earth to avoid catastrophes, they want to learn how to predict CMEs to prepare for something that could potentially knock out power or communication to large areas of our planet.
Scientists have also learned some interesting things about the Sun’s temperature during total eclipses. They had measured the temperature of the Sun’s surface to be 6,700 to 11,000 degrees F (3,700 to 6,200 degrees C). However, by observations made during total eclipses, they found that the temperature of the chromosphere is up to 14,000 degrees F (7,700 degrees C) and the corona is 3.5 million degrees F (2 million degrees C)! They are still trying to discover how that is possible.
With a total eclipse of the Sun less than a week away, let’s consider why solar eclipses happen.
A solar eclipse can occur only at the time of the new moon. The Moon appears to us in phases, and the principle phases are new moon, first quarter, full moon, and third (or last) quarter. Those phases are dependent on the relative position of the Sun, Moon, and Earth. The entire sequence of phases takes about 29.5 days, which is a synodic (or lunar) month. The new moon is the time when the Moon and the Sun are on the same side of the Earth.
Obviously, if the Moon is on the side of Earth where the Sun is, we can’t see the Moon at night. It also means we usually can’t see it during the day because the Sun’s brightness hides it except when the Moon passes in front of the Sun. When the Moon only partially blocks the Sun, we see a partial eclipse. When the Moon is precisely aligned with the Sun, we see a total eclipse.
During a total eclipse, the Moon casts a moving shadow over a portion of the Earth. Those who are outside of that shadow can still see a partial eclipse. How much of the Sun is hidden by the Moon depends on how far the viewer is from the shadow. People all over North America will see the eclipse that is coming as a partial eclipse. It will only be total for those who are in the 70-mile-wide path of the shadow that will travel from Oregon to South Carolina.
A few days ago we wrote about the Search for Extra-Terrestrial Intelligence (SETI). The newest SETI project is in the news because the Chinese government can’t find anyone to manage it. That is in spite of the fact that the chief scientist-manager will receive a $1.2 million-dollar salary plus housing. The job is to supervise the operation of the world’s largest “filled aperture” radio telescope.
This new telescope is designed to search for radio signals from intelligent life in the universe up to 1,000 light-years away as well as to monitor pulsars and detect interstellar molecules. Its name is Five hundred meter Aperture Spherical Telescope (FAST) because it is 500 meters (1600 feet) in diameter. It was constructed in a natural basin in southwest China at the cost of $180 million dollars. Since FAST can’t be turned to receive signals from different directions, it is made up of 4450 metal panels that can be rotated independently to pinpoint different areas of space. Construction has been going on since 2011, and it’s in the testing stage now.
Sixty-five people lived in a village located in the valley where FAST was built. The Chinese government evicted them. Also, to prevent interference from electronic devices in the area, more than 9,000 residents within 5 km (3.1 miles) of the site were also relocated. They were given about $1800 each for relocating. About 500 families tried to sue over the demolition of their homes without adequate compensation. In the end, the Chinese government spent about $269 million to relocate the previous residents in addition to the cost of the telescope.
Now China is searching the world to find someone to manage the operation of FAST. So far they have had no success in spite of the large salary. There are several reasons why they haven’t filled the job. For one thing, the area is very remote and doesn’t have much to offer in the way of entertainment or activities. Also, because of the failure rate of the mirror activators, any scientist who wants to spend time in research using the telescope may end up mostly dealing with technical problems. In addition to those factors, the Chinese government has placed very high requirements on potential job applicants. With the educational and experience requirements, there may be only a handful of qualified candidates in the world.
China will eventually find someone to manage FAST. Calibration of the radio telescope is projected to take three years. Then the operation will require hundreds of astronomers and the SETI project will spend years and large sums of money searching for intelligent life in the universe. We have said many times before that whether life exists anywhere else in the universe has nothing to do with whether God exists. God could choose to create life anywhere, but so far the effort to find signs of intelligent life beyond our planet has not been promising.
Evolutionary biologist Richard Dawkins is an outspoken atheist. He has made harsh statements against all religions. In his book The God Delusion, he uses the vilest terms to describe “the God of the Old Testament.” Then he goes on to say that God is not only a delusion but a “pernicious delusion.” However, in a backhanded way, Dawkins admits anti-Christian discrimination. He has admitted that Christianity is treated differently from Islam, and coincidentally that Christians are more gracious and forgiving than Muslims.
Dawkins was scheduled to speak in August at an event in Berkeley, California, sponsored by a public radio station. Dawkins was supposed to be speaking concerning his newest book coming out this month–Science in the Soul: Selected Writings of a Passionate Rationalist. Residents in the San Francisco Bay area reported to the radio station some comments concerning Islam in The God Delusion. They also pointed out a tweet from Dawkins in which he said, “”Islam is the greatest force for evil in the world today.” When the powers at KPFA radio heard that, they promptly canceled Dawkins’ speech. They sent a letter to those who had purchased tickets telling them, “We had booked this event based entirely on his excellent new book on science, when we didn’t know he had offended and hurt–in his tweets and other comments on Islam, so many people.”
A response letter from the Dawkins Foundation referred to him as “one of the greatest intellects of our time” and called the accusation that he had used “abusive speech” toward Muslims “baseless.” Dawkins himself stated, “The idea that I have engaged in abusive speech against Islam is preposterous…I have indeed strongly condemned the misogyny, homophobia, and violence of Islamism.”
In a letter written to the radio station by Dawkins, he stated, “I am known as a frequent critic of Christianity and have never been de-platformed for that. Why do you give Islam a free pass?” In other words, Dawkins can feel free to criticize and mock Christianity, but not Islam. Could that be because Christians are more gracious and forgiving? Could it be that he can insult Jesus and his followers and not fear for his life? Would he be able to do the same against Mohammad and his followers? I don’t think so. His words are a backhanded compliment to the faith he has frequently criticized.
There is another aspect of the decision by the radio station. The public radio station canceled the speech stating “KPFA does not endorse hurtful speech” and “we do not support abusive speech.” Would they have canceled because of Dawkins’ “hurtful speech” or “abusive speech” toward Christians? His vile words about the God of the Bible in his book The God Delusion would certainly qualify as “hurtful” and “abusive” toward the faith of Christians and Jews. I am confident that the radio station would not have canceled because of those words. Even Richard Dawkins admits anti-Christian discrimination exists in the media and academia.
Chinese scientists have conducted at least three experiments to create genetically modified human embryos. Now, MIT Technology Review reports that a team of scientists in the United States has edited the DNA of human embryos. The experiment was performed at Oregon Health and Science University, a public university in Portland, under the leadership of Shoukhrat Mitalipov. It is apparently the first time this has been done in the United States, and it involved a greater number of embryos than the Chinese experiments.
Mitalipov, who was born in the former Soviet Union and received his Ph.D. in Moscow, came to the U.S. because there was a lack of funding for genetic experimentation in his home country. Since coming to the U.S. he has cloned monkeys and human embryos. This is the first time for editing the DNA of a human embryo.
The scientists used a gene-editing tool called CRISPR, which we have reported on before. The goal of the experiment is supposed to be to find a way to correct genetic defects in humans. The sperm used to fertilize the embryos came from a man with a genetic defect. The embryos were destroyed after a few days because in the United States it is illegal to allow genetically modified human embryos to develop into full-term babies.
In February the U.S. National Academy of Sciences gave support for creating gene-edited babies if the purpose is the elimination of serious genetic diseases. Genetically modified human embryos can develop into gene-modified humans who will pass on the genetic changes to their offspring. This may offer hope for eliminating genetic defects. However, it also has implications for the nightmare scenarios of a science-fiction movie. When humans start to play God by manipulating the DNA of our children, what if they make a disastrous mistake? The United States Intelligence Agency listed CRISPR as a potential “weapon of mass destruction.”
Beyond the implications of Frankenstein-like creatures, there is the aspect of “designer children.” DNA could potentially be edited to select the sex, physical features, and even intelligence of an unborn child. So far that is illegal in the United States, but not in other countries. One of the problems the Chinese experimenters encountered is called “mosaicism,” in which the change to the DNA is not taken on by all of the cells. The implications of a person with multiple DNA codes in different cells is not fully understood. Other CRISPR errors referred to as “off target” effects could result in serious genetic defects. Mitalipov’s team claims to have those problems under control.
The report from this U.S. experiment should be published soon, and it will certainly be in the news. Christians should be concerned about where this is leading. Do humans have the right to play God with our DNA? What could be the result of “off target” mistakes? What about the ethics of creating human embryos for experimentation and then destroying them? Do the possible breakthroughs in the elimination of genetic diseases outweigh the dangers? What about the moral cost to our society as we go down this road?
One thing you can be sure of is that humans will continue to create genetically modified human embryos. If it doesn’t happen in the United States, it will happen in other countries. You can also be sure that there will be some scientists who will do so with less than pure motives. In Mary Shelley’s classic book telling about a scientist’s desire to create a new species, Victor Frankenstein said, “A new species would bless me as its creator and source; many happy and excellent natures would owe their being to me. No father could claim the gratitude of his child so completely as I should deserve theirs.” The power to become a god creating new species of humans can overpower pure motives as it did with Victor Frankenstein. The outcome could be even more tragic than in the novel.
Government and Christianity have not always been in harmony. Christianity began under the rule of the Roman government, which abused human rights and promoted immorality. Although persecuted, the Christian faith grew strong and brought many people to the realization that our real hope lies not in government, but in God. In spite of the oppression by the Roman government, the Apostle Paul instructed Christians to honor those in authority (Romans 13:1-6) and to pray for them (1 Timothy 2:1,2).
We have always pointed out that Christianity is not an American institution. When we argue for the validity of Christianity and attempt to provide scientific support for the existence of God, we do not bring American politics into the discussion. In spite of that, the Christian faith has played a vital role since the founding of this country and even before that.
God blessed the United States with a standard of living higher than the world had ever seen. We argue for the truth of Proverbs 14:34 which tells us, “Righteousness exalts a nation: but sin is a reproach to any people.” We sing “God Bless America” as a hymn to ask God’s continued blessing on our nation. We place “In God We Trust” on our money. But today America seems determined to reject God and His teachings.
Righteousness in our government seems to be eroding and several groups have been formed to fight against that trend. One of those groups is Judicial Watch (www.JudicialWatch.org). This organization seeks to expose corruption in the American government and in organizations that have government connections. It is bipartisan in its efforts exposing both Republican and Democrat corruptions.
Judicial Watch publishes a magazine, and in their July issue, they have a report of abuses in the Veteran’s Administration. Those who are interested or active in American politics may find this a useful resource. Paul wrote that “the one in authority is God’s servant for your good” (Romans 13:4). Christians can serve to remind those in authority of their sacred duty. Government and Christianity can work together to benefit all Americans as well as those in other countries.

In each issue of our printed publication, we have a feature called Scientists and God, in which we quote from a leading scientist who is also a believer in God. Today I would like to do something a little different. I want to quote the words of a leading scientist who was not a believer.
J. B. S. Haldane (1892–1964) was a British geneticist and evolutionary biologist. He was also an outspoken atheist and a Marxist. Because of the political controversy caused by his Marxist ideology, he left England in 1956 and spent the remainder of his life in India.
Haldane was a brilliant man who made contributions in the areas of genetics, evolutionary biology, and mathematics. In many ways, he was ahead of his time. He proposed the central ideas of in vitro fertilization. He was the first to suggest human cloning. In fact, he coined the use of the term “clone” for that purpose. He also helped to create the science of population genetics.
Haldane proposed correctly that sickle-cell disease gives immunity to malaria. He prepared gene maps for color-blindness and hemophilia. Nobel Prize winning biologist Peter Medawar called Haldane “the cleverest man I ever knew.”
In 1929, Haldane introduced the “Primordial Soup Theory,” which said that life began on the early Earth in a chemical soup where the elements of life came together. That theory became the leading concept of abiogenesis–the idea of life coming from non-living matter by a natural process. Haldane’s theory led to the famous Miller-Urey experiment in 1952. In that experiment, Stanley Miller created a sealed container with the chemicals thought to have been part of the early atmosphere of Earth. He subjected the chemicals to an electric spark and collected some amino acids which are the building blocks of proteins. The news media went wild over “creating life in the laboratory,” but that was an example of media exaggeration–or as it would be called today “fake news.”
Incidentally, science has since shown that the Miller-Urey experiment did not emulate the conditions or chemicals of the early Earth and therefore is not a valid demonstration of the first step in abiogenesis. However, it is still shown to students in school textbooks because science has not produced anything better, and it is easy to understand. Today’s attempts at abiogenesis are far more complex, proving that it takes great intelligence and carefully controlled lab conditions to produce even the basic building blocks of life. In other words, it takes intelligence to create life, which has been our message for many years.
Haldane wrote numerous books presenting his ideas and defending Darwinism. In 1949 he debated British ornithologist Douglas Dewar on the topic “Is Evolution a Myth?” In that debate, Haldane said that evolution would not be capable of producing “various mechanisms, such as the wheel and magnet, which would be useless till fairly perfect.” In other words, if those mechanisms could be found in living organisms it would be an indication that evolution did not create those organisms.
Since that debate, we have found magnets in anaerobic bacteria which are considered to be the most “primitive” forms of life. The sightless, single-celled magnetotactic bacteria consume iron and produce magnets which they use to guide them to anaerobic areas that are safe for them to live. The magnets they produce are better for some scientific purposes than what humans can produce in the laboratory. Turtles, birds, and other more advanced animals also use magnets for navigation. Wheels can also be found in living organisms. As Janine M. Benyus (another Darwinist) wrote in her book titled Biomimicry, “Even the wheel, which we always took to be a uniquely human creation, has been found in the tiny rotary motor that propels the flagellum of the world’s most ancient bacteria.”
About 2300 years ago in ancient Greece there lived a man named Epicurus. He spent his time thinking about things and taught others about the things he was thinking. One of the things Epicurus thought about was death. That’s not unusual. There has never been a living human being who has not thought about death at one time or another. But Epicurus was a professional thinker (also known as a philosopher), so his thoughts were influential. What do we hear from Epicurus on death and fear? In his thinking, he concluded that death was the end of body and soul. When we die, we just cease to exist and therefore, he said, death should not be feared.
Epicurus died in 270 B.C. at the age of 72 in great pain because of kidney stones. However, he wrote a letter in which he said it was, “a happy day to me, which is also the last day of my life.” Since Epicurean philosophy says that death is nothing to be feared, why do people still fear death? Perhaps it’s because most people think that Epicurus was wrong.
What is the source of the greatest joy and fulfillment in life? Isn’t it love? The relationships we have with others bring us happiness and give us purpose as well as joy. Loving and being loved by family and friends is the greatest of human experiences. God never intended for us to be alone. (See Genesis 2:18.) Being rejected by those we love is the source of the greatest pain. Interestingly, Epicurus believed that a happy life is one in which friends surround us. We know that nothing makes us as sad as the loss of those we love. Death is the most permanent form of separation and loss. Death steals away those we love one-by-one if we manage to live long enough. Death gives us much to fear, and then finally death comes to take us.
If Epicurus is right, then death is the end of love. If there is no existence beyond the grave, there is no love. If you believe that death is the end of existence, seeing a loved one dying is the most fearful and terrible experience in life. But what if death is not the end? What if love goes on? Genesis tells us that death was not part of God’s original plan for humans. Death is a consequence of human sin. Jesus wept at the tomb of his friend Lazarus out of sympathy for Mary and Martha. He must also have been weeping over what sin had done to the human race. Grief and anger over the mess brought on by human disobedience touched the emotions of the human Jesus.
But Jesus was more than human. He is also God. He had the power to bring Lazarus back from the grave and restore him to the sisters who loved him. But that resurrection was only temporary. Lazarus, as well as his sisters, died at some later time. Soon after raising Lazarus, Jesus conquered the power of death once and for all. His death brought both fear and grief to those who loved him. But as Timothy Keller wrote in Making Sense of God, “…the darkness of death swallowed Jesus, he entered it, but then he blew a hole out of the back of it.” The pain of those who wept was turned to joy as Jesus was alive again. When Jesus conquered death, he brought not only joy but also hope. Death is not the end of love and relationships. Love goes on.
