Exoplanets and Life in the Universe

Exoplanets and Life in the Universe
Artist’s Conception of Alien Planets

“Star Wars,” “Star Trek,” and other movies and television shows featuring space travel and alien life have fascinated people for decades. Yesterday, we examined how intergalactic travel would not be anything like what the movies depict. Other galaxies are many light-years away, and the laws of physics will not allow us to travel even one percent of light speed. Nevertheless, people are still concerned about exoplanets and life in the universe.

Regardless of whether we can go to other galaxies far, far away, or even solar systems within our own galaxy, astronomers are searching for “exoplanets.” An exoplanet is any planet outside of our solar system, and scientists are trying to find one that could support life. (We have dealt before with the question of why the universe is so large.)

Scientists look for planets orbiting stars that are so far away we can’t even see the stars with our unaided eyes. How is it possible to find planets that we can’t see, even with our best telescopes? They use at least three methods. When a planet transits in front of a star, it blocks a small amount of the star’s light. Very sensitive instruments detect that change. A star may wobble slightly because of orbiting planets, causing a detectable color shift due to the Doppler effect. Finally, astronomers sometimes use gravitational lensing to detect an orbiting planet if it causes bending of the light from a distant star.

Those are some methods astronomers use, hoping to find exoplanets and life elsewhere in the universe. However, unlike in the movies, the stars and their planets are so far away that we could never go there. Even sending a radio signal to those possible planets would take thousands or even millions of years, traveling at the speed of light. Getting a message back would take an equal amount of time.

There are so many requirements for life that the chances of any of those planets supporting advanced life would be almost infinitely small. If there is some form of life on any of them, how will we ever know? God could have created life elsewhere in the universe, but we have no evidence one way or the other. The Bible doesn’t tell us, and science can only look and hope for a clue. Whether or not life exists on other planets or moons, we believe the fine-tuning of Earth for life is evidence for God’s existence.

Space-Travel Adventure Movies

Space-Travel Adventure Movies

Space-travel adventure movies and novels may be fascinating, but they are not very realistic. Traveling through space poses many hazards to humans beyond equipment failures. There is also the danger of radiation exposure when a person leaves Earth’s protective atmosphere and magnetic field. And perhaps the most significant of all is the issue of time.

Travel to the Moon will take days. Traveling to Mars will take months. A space-travel adventure to any planet outside of our solar system would take multiple lifetimes. Astronomers have toyed with the idea of traveling to a planet orbiting Proxima Centauri, which is the closest star to us. That planet, Proxima Centauri b, is 42 light-years from Earth. Unless someone could find a way to travel through a wormhole, if such a thing exists, it would take 6,300 years to make the journey with present technology.

We are considering the present technology to be the speed of the Parker Solar Probe launched in 2018, which is 430,000 miles (690,000 km) per hour, or about .064 percent of light speed. According to Astronomer Dr. Hugh Ross, the laws of physics would limit the top speed of a spaceship to about one percent of light speed, but we are far from achieving that. Also, a factor to consider would be a way to slow down on approaching the destination to avoid going right past it or crashing into it.

So, if we sent out a space-travel adventure crew to Proxima Centauri b, it would take many generations to arrive. That means people would have to reproduce many times on the way. Factors to be considered would have to include having enough crew members and genetic diversity to have a healthy crew on arrival at the destination. Using computer modeling, scientists have determined that the minimum team required would be 49 males and 49 females. Ninety-eight crew members would need a large ship. In addition, there would have to be facilities for recreation and to grow food.

The vast majority of the travelers on this spacecraft would never see Earth or the destination planet. Exposure of many generations to the radiation of outer space could cause physical or mental deformities that we can’t imagine. What if this small community just couldn’t get along together in cramped quarters? Avoiding a mutiny or rebellion would be a significant challenge. Keeping hundreds of generations focused on the same mission would be impossible. Putting the crew into a cryogenic state for thousands of years to avoid the multi-generation problem does not seem to be realistic. (Remember the movie “2001: A Space Odyssey?”) 

Producing food and recycling water would be essential for such a space-travel adventure. However, taking and preserving all equipment and materials needed for the crew to survive in a hostile environment on arrival at the alien planet would be impossible to plan or predict.

We may enjoy science fiction such as “Star Trek,” “Star Wars,” or “Lost in Space,” but none of them are even remotely realistic. God has given us a beautiful planet with everything we need to survive and thrive. What we must do is take care of it. That means using resources wisely, protecting the environment, and protecting the animals that share the planet with us. Stewardship of God’s gifts was a command from the beginning. (See Genesis 2:15.)

Life After Death – A Concept Common to Humans

Life After Death – A Concept Common to Humans

Humans from the earliest times have believed in life after death. One of the unique human properties is that we alone believe in a continued existence when our physical life has ended. Most animals simply abandon a dead member of their species. There has been some attempt to claim that elephants, whales, and apes exhibit mourning and stay with the body of a deceased member of their group. However, many researchers agree that interpreting their actions as mourning is not justified. Humans tend to view animal behavior in our image, a process known as anthropomorphism.

As science discovers more fossils of ancient humans, the pattern of preparing a deceased member of the group for another existence becomes apparent. Anthropologists are interested in a South African cave system burial site. There they have found 28 skull fragments and six teeth of what appears to be a child with human characteristics 35 feet (10.6 m) below ground. The bones do not seem to have been washed into the cave or dragged in by scavengers or predators. Researchers gave the specimen the scientific identity of Homo naledi.

Lee Berger of the University of Witwatersrand in Johannesburg reports that this fossil shows strong evidence of a “ritualized body disposal” of the specimen, which they nicknamed “Leti.” Ancient burial sites have almost always indicated that others prepared the deceased for life after death. Sometimes the body is mummified, and sometimes jewelry or weapons are left with the body. There are even cases where an animal or mate was buried with the deceased.

There is a scant reference to life after death in the Old Testament. In 2 Samuel 12:23, David expressed faith that he would see his deceased baby in the future. Job said that after his body had been destroyed, he knew he would see God (Job 19:25-27). Daniel saw a “man clothed in linen” who told him he would “rest” and then “at the end of the days” he would rise and “receive his allotted inheritance” (Daniel 12:13).

The New Testament is full of references to life after death, especially in the teachings of Jesus Christ. The war between good and evil is rooted in the understanding that death is a product of this physical world and Christ has conquered it. (See 2 Timothy 1:10; Revelation 20:14 and 21:4.)

Human spiritual nature is unique because God created us in His image. Our soul allows us to think beyond this life and anticipate an eternal, time-independent relationship with God. That concept has been present in humans from the very beginning and is still present today. Our spiritual nature allows us to express ourselves in art, music, and worship. It also gives us the hope of eternal life in an existence beyond anything this world has to offer.

The Wall Hezekiah Built Is Uncovered

The Wall Hezekiah Built Is Uncovered
A stone wall of similar construction to Hezekiah’s wall.

The winter 2021 issue of Biblical Archaeology Review contains an announcement by the Israel Antiquities Authority of what they call a “groundbreaking discovery.” Archaeologists have uncovered the wall Hezekiah built around 701 B.C. Isaiah 22:9-10 describes the wall’s construction, and 2 Kings 25:10 tells of its destruction during the Babylonian siege of Jerusalem about a century later. In addition to the wall itself, the archaeologists found various objects, including seals, along the wall’s base to confirm its date.

The archaeologists say that the wall was 10 feet (3 m) tall and more than 15 feet (4.5 m) wide. It was built along the slopes of the steep-sided Kidron Valley, making an imposing barrier on that side of Jerusalem. Researchers previously found other sections of the wall Hezekiah built, but this find connects those sections and provides more verification of the biblical account. The same issue carries a report of finding evidence of the powerful earthquake that occurred during the reign of King Uzziah and is described in Amos 1:1 and Zechariah 14:5.

Many people don’t realize that archaeological work in the Middle East is in its infancy. Hundreds of identified sites have not been excavated because of the expense involved. In addition, the field of archaeology is complicated by politics, nationalism, funding, and the prejudice of some of the people directing the digs and the museums displaying the artifacts.

To help people learn more about biblical archaeology, we have produced a video series titled “Beyond Reasonable Doubt” with John Cooper. The videos are available for free viewing on doesgodexist.tv, or you can purchase the series on DVDs. The series is an introductory presentation of positive evidence for the reliability of the Bible and is recommended for class use and individual viewing.

Drug Safe-Havens Don’t Work

Drug Safe-Havens Don't Work

On December 1, 2021, the United States joined Canada, Australia, and Europe in allowing drug safe-havens for people who wish to use heroin and other narcotics. Mayor Bill de Blasio of New York City announced that having monitored facilities where someone watches for overdoses will save lives. The first facility in New York was set to open immediately.

Federal laws ban operating a place for narcotic use, but those laws have been poorly enforced. It is interesting that there is no evidence that these facilities provide help for those who are addicted. There have been negative results in other places where governments have tried legalization. Other moral issues such as prostitution and sexual abuse become part of the scene.

Setting up drug safe-havens, making it easier for people to use narcotics, is sanctioning people to harm themselves. Even though they may not die immediately from drug usage, the long-term result is not good. Should the government provide a way for people to become addicted? The news releases on the New York City plan do not say that drugs will be provided. If that is true, drug dealing and the problem of contaminated drugs will continue.

Licensing sin has never worked, and neither will drug safe-havens. Instead, the legalization of gambling has increased crime, prostitution, economic damage, and family breakdown. As the world turns away from God and denigrates the teachings of Jesus, we are not surprised that politicians will seek to condone the sin industries and tax them.

In 1 Thessalonians 5:21-22, Paul admonishes Christians to “Bring everything to the test and cling to that which is good and rejecting all that has a look of evil about it.” Therefore, let us oppose the movement of our nation toward embracing the sin industry as it offers an alternative to the teachings of Jesus Christ.

Some Good News about Diseases

Some Good News about Diseases

Recent data on disease brings some good news. Cancer has been a major challenge for medical science, but survival rates for cancer have been increasing. Between 1975 and 2016, the percentage of people living for five years after a cancer diagnosis has risen from 50% to 68%. In 1971. three million people in the United States had survived cancer, or 1.5% of the population. In 2019, that number was 16.9 million, 5% of the population. Human pollution and poor life choices cause many cancers, but God has given medical science the ability to combat this dreaded disease.

Also, some good news is what vaccines have done for survival. A better understanding of God’s design of the human body has allowed us to combat diseases with vaccines. Before the vaccine for smallpox, 48,164 people contracted the disease in the United States. Since the vaccine’s development, that number has dropped to zero as of 1998. Diphtheria brought severe illness and usually death to 175,885 people in the U.S. Since the vaccine, there has been one case. Polio affected 16,316 people in the U.S. before the vaccine. Since then, there have been no cases. Measles was a significant cause of birth defects and other health issues and affected 503,282 people in the U.S. After the vaccine, there have been 89 cases.

We thank God for some good news regarding these human afflictions. The more we learn about diseases, the more we understand that they are not “God caused” but often result from human actions and carelessness. It is a tragedy that some people refuse what God has given us to prevent illness and death.

Inconsistent Fetal Laws

Inconsistent Fetal Laws

Yesterday, the United States Supreme Court heard arguments on a Mississippi law prohibiting most abortions after 15 weeks. Protestors on both sides of the abortion issue were active outside of the Supreme Court building. Many abortion advocates, including politicians, have threatened violence if the court strikes Roe v. Wade. Unfortunately, there are no easy answers as people argue about women’s rights and unborn babies’ rights. While research continues to show the humanity of the unborn child, we see inconsistent fetal laws. 

More than 38 states in America have “fetal assault laws” on the books. In the past 15 years, about 1200 American women were criminally charged for taking illegal recreational drugs resulting in a miscarriage. If someone assaults a pregnant woman, killing the baby, that person is guilty of murder in most states. This was true in Old Testament times as well (See Exodus 21:22-23). 

Researchers at the University of Oxford had the rare opportunity to study gastrulation of a human embryo from an abortion16 to 19 days after fertilization. Lead researcher Shankar Srinivas, an expert in developmental biology, explained that gastrulation is a process that begins about 14 days after fertilization. At that time, different cells emerge and arrange themselves to form various organs in the human body. The new research into gastrulation has the potential to open ways to prevent congenital abnormalities. 

The research by Dr. Srinivas gives a glimpse into early human development. When fertilization occurs, we are dealing with a human, not a blob of chance cellular accumulation. The complexity of this system speaks of God’s design and is precious and unique. A news report quoted Dr. Daniel Sulmasy, the director of the Kennedy Institute of Ethics at Georgetown University, saying that this research shows “recognition of the humanness of the embryo.” 

It is within our grasp to prevent conception and avoid the destructive actions of an abortion that can also cause physical and mental harm to a woman. It starts with understanding that sex is not a meaningless physical act but a joining of two people in a deeply personal relationship. That was God’s plan from the beginning. We understand more and more about how this design works, and a consistent approach to the facts can lead us toward an end to inconsistent fetal laws.

Women Had to Wear a Head Covering

Women Had to Wear a Head Covering

We recently heard from a female skeptic who said that no woman could accept the biblical teaching that women had to wear a head covering or a veil that hid their face. She was referring to 1 Corinthians 11:5-6 where Paul writes, “Every woman that prays or prophesies with her head unveiled brings shame on her head, for that is to make herself like one of the shameless women who shave their heads. For if a woman will not veil herself, then she should cut off her hair, but since to cut her hair short, or shave it off, marks her as one of the shameless women let her be covered.”

This is an excellent example of what any reader of ancient documents needs to understand. You must look at who wrote the document, to whom they wrote it, why they wrote it, and how the people to whom it was written would have understood it. For example, the Greek culture of that day demanded that women had to wear a head covering when out of their home. Otherwise, she was advertising that she was a prostitute.

Paul wrote the Corinthian letters to a particular group in a specific culture. Even today, when we visit a culture that attaches a particular understanding to what a person wears, Christians need to be sensitive to what their clothing conveys. In 1 Timothy 2:9, Paul also cautions Christian women to avoid “pearls or costly dresses.” He says he would not eat food that would offend someone if doing so would cause a person to be misled by his example (1 Corinthians 8:8-13).

In those same verses, he points out that Christians have the freedom to eat anything. However, being concerned about how our dress and actions affect others must have a higher priority than expressing our freedom. That is a lesson the American culture needs to learn today.

So That’s How God Did It!

Fluorine - So That’s How God Did It!

Many years ago, I heard a research scientist who was also a Christian explain his philosophical approach to research by saying, “So that’s how God did it!” For many of us working in scientific fields, that is what science is about. When researchers announce a new discovery, we view it as knowledge that helps us understand what God has done in creating the cosmos and humans.

Researchers at the University of Hertfordshire in the U.K. have just announced a solution to one of the chemical mysteries that has baffled astronomers for a very long time. Our bodies contain some common elements that were created in star explosions which scientists have observed. The origin of some trace elements in the human body, such as fluorine, was not easy to determine. Most of us know that fluorine is a critical component of bones and teeth. Toothpaste contains fluorine in the form of fluoride.

Rare stars known as Wolf-Rayets are very massive, and they survive for a relatively short time before exploding. Using the Atacama Large Millimeter/submillimeter Array (ALMA) of 66 radio telescopes in Chile, researchers detected gas clouds with large amounts of hydrogen fluoride in Wolf-Rayet stars. Scientists could not confirm fluorine production in local stars, but they solved the mystery by finding fluorine in a galaxy 12 billion light-years away. The director of the study commented to CNN that Wolf-Rayets have allowed humans to maintain good dental health.

The simple statement “In the beginning God created the heaven and the earth” (Genesis 1:1) involves a process that science strives to understand. As we gain more knowledge of what is involved in that process, we see that “the heavens declare the glory of God and the earth shows the work of His hands” (Psalms 19:1).

Theologians may simply say that God “spoke the creation into existence,” but scientists want to know how. Scientists who are Christians rejoice in a new understanding of God’s handiwork. As we come to understand how God has done wonderful things, we say, “So that’s how God did it!” Then we thank Him for designing a creation in which we can survive.

Treating Gender Dysphoria

Treating Gender Dysphoria

What response would you make to a 14-year-old girl who has decided she is really a boy and wants doctors to surgically remove her breasts and put her on a puberty blocker and hormone therapy regime? The UCLA School of Law and the American College Health Association tell us that the number of girls seeking treatment to have their sex changed has risen dramatically. In 2008, it was one in 2,000, and in 2020, it was one in 20. There are now over 50 clinics treating gender dysphoria in the United States. There was one in 2007.

Many young people have severe depression issues and are frequently suicidal due to gender dysphoria. Experts debate the cause of this phenomenon while treatments being used are causing more problems. The question is how to go about treating gender dysphoria. Many transgender cases are due to social contagion as friends influence a young person to “come out” as trans. There are online forums of trans teens with large numbers of participants.

An increasing number of transgender persons regret their decision to change their gender. Some have even sued clinics for rushing them into the decision to change without adequate counseling. Many times other mental health issues are involved. Having your testicles or breasts removed is irreversible. Also, the drug treatments are for life and have side effects that may be medically difficult to manage.

The Bible says God created male and female (Genesis 1:27). The original plan works, but surgery, drugs, and a rejection of God’s design have changed that. The tragic result sometimes leaves innocent victims who are negatively affected by what others have done.

The real complication is that treating gender dysphoria has become a political issue. For example, The Week magazine (October 29, 2021, page 11) carried an article about LGBTQ activists committing violence against scientists and doctors who have suggested applying caution regarding medical intervention in trans situations.

Christians must respond to this with love, compassion, and caring. We should do everything we can to help everyone enjoy the blessing of being a confident male or female in an age of confusion and frustration.
