Another Lesson from (Recent) History

The older I get, the less confidence I have that the history presented by the media is correct. I was in high school from 1951 to 1955, and the sitcoms and movies that I see of things that supposedly happened during that period are so far from what really happened that I wonder where the people who make these programs got their information.

The April 2017, issue of Astronomy magazine, contains an article by Bob Berman telling of what actually happened in the Russian Mir space station from 1986 to 2001. The media reports at that time painted a very idealistic picture of great cooperation, wonderful technological achievements, and trouble-free living in space. We know now that the Russians controlled reports by cutting the pay of anyone who complained about what was happening on Mir or told of any negative events.

This is the twentieth anniversary of the time when United States astronauts inhabited Mir. When medical doctor Jerry Linenger arrived on Mir in 1997, he found clutter and leaky pipes. Propylene glycol was leaking into the air so the astronauts had to wear breathing masks and were not allowed to exercise because they couldn’t breathe deeply. The climate-control was dysfunctional, so the temperature stayed around 90 degrees. On February 23, 1997, an oxygen-generating canister exploded creating a fire that nearly killed everyone on board. On June 25, 1997, a supply ship rammed Mir once again nearly killing everyone on board. Berman calls Mir “a bit of a death trap.”

Media portrayals of what happened in biblical times are even more difficult. The portrayal of Noah’s Ark in the “Ark Encounter” and the movie Noah as well as movies about the Passion Week, and the entire Genesis account have been embellished, westernized, and modernized by the media and entertainment industries leaving completely erroneous concepts of what really happened. The biblical narrative uses an economy of language because the focus is not on the event itself but on the meaning of the event. We can trust the biblical narrative, but we need to be careful about buying into the media presentations of biblical events. There is a difference between history as revealed in God’s Word and history as shown in modern media portrayals.

Travel in Space

Travel in Space
Popular movies portray travel in space as just being a matter of solving simple propulsion problems. The truth is that cosmic radiation is now better understood as a huge risk to space travel. In Scientific American (February 2017, page 54) Charles Limolihas wrote an excellent scientific discussion of the dangers of cosmic radiation.

Galactic cosmic rays are charged atomic nuclei flying at nearly the speed of light, probably coming from the supernova remnants of dead stars. Our Sun generates a great amount of radiation, but the cosmic rays are much more of a hazard. When these atomic nuclei hit molecules in our body, they ionize atoms, knocking electrons off the atoms and causing the atoms to become charged. These charged atoms hit other atoms, and there is a domino effect that is greatly magnified because of the extra energy involved. In human bodies, there are clusters of damage from such radiation, and just trying to duplicate the process in the laboratory has turned out to be incredibly difficult. Limolihas and his fellow researchers have shown that there is a much greater effect on brain tissue than anyone imagined.

The Earth is designed to handle this huge radiation by having two levels of shielding. The Earth’s magnetic field sweeps galactic cosmic rays away from the areas of the planet where most people live, and the atmosphere stops much of the rest. The amount of cosmic radiation we receive on the surface on Earth’s surface is relatively harmless. When you travel in space beyond Earth’s magnetic field, you, have virtually no protection, and that is going to be a huge challenge for space engineers to solve.

The lesson we would bring from this is that God’s design of Earth becomes more and more amazing as we learn of the complexities that have to be taken care of for you and me just to get up in the morning.

Global Warming Nonsense

Global Warming Thermometer
The “hot button topic” for a wide variety of people today is the issue of global warming. It is easy to understand why political figures want to use this issue to manipulate their followers, but followers of Jesus Christ seem to be getting swept up in the paranoia also. Jesus said, “Take care that no one misleads you. For many will come claiming my name and saying, ‘I am the Messiah’; and many will be misled by them. The time is coming when you will hear the noise of battle near at hand and the news of battles far away; see that you are not alarmed. Such things are bound to happen; but the end is still to come. For nation will make war upon nation, kingdom upon kingdom; there will be famines and earthquakes in many places. With all these things the birth-pangs of the new age begin” (Matthew 24:5-8 NEB). We need to be informed, but global warming is not of eternal significance. Some people try to make a religion of climate change. We can get involved scientifically or politically if we so choose, but let us not get involved religiously.

So what are the facts?
#1. Climate change is happening. Anyone can look at climate data worldwide and see the changes on a global scale. This is global–not local. We just had the warmest winter here in Michigan that I can remember, and I have lived here almost 60 years, but that is not directly due to global warming.

#2. This is not the first time. The Earth’s rocks show periods of warming and cooling. Natural processes cause changes in the Sun which affect the Earth. Geologic events such as volcanic eruptions can affect climate for long periods of time.

#3. Humans have altered the planet. This isn’t even worth commenting on, and what we have done has effects that are still unknown. God told us to “take care of the garden” (Genesis 2:15), and as custodians of the planet, we need to take care of it. Releasing greenhouse gasses indiscriminately would seem to be failing to do that.

#4. There are consequences to what we do and what we don’t do. As an example, cancer is mostly caused by human actions. The list of diseases human actions have caused or catalyzed is enormous. Not managing Earth’s resources well has cost us dearly in the past, and it will do so in the future.

Jesus said not to let these things disturb our minds. As Christians, we need to keep our eye on the cross and on our journey to an eternal home free of global warming, war, and all the other things that concern people about the physical world in which we live. The physical is important, but the spiritual is far more significant.

Bioethics and Playing God

DNA Molecules

Over the past several months, the media has published dozens of articles about a new genetic technique of modifying DNA called CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats). This method can be used to edit the embryonic or reproductive cells of human beings, passing on genetic changes to future generations. It makes altering our DNA faster and easier. The media has emphasized the possible positive impact of this technique. The Week magazine (March 14, 2016) called it “genetic research nearing a breakthrough that could transform the world.” We know that many diseases are genetic in nature, including sickle-cell anemia, Huntington’s disease, muscular dystrophy, and some forms of cancer. The problem is that with some 20,000 genes involved and the fact that genes interact, the possible negative consequences of making permanent changes to human DNA are very high. This technique could potentially be used to alter the genomes of a child to suit parental preferences. The question is whether CRISPR will be used for therapy or enhancement or both. This bioethical question cannot be answered by science alone.

For almost 50 years, this ministry has tried to demonstrate how science enhances faith. At the same time, faith can answer questions that science cannot answer. The question of shaping the human body to suit our desires is an issue of science and faith because we are more than just a body. We were created in God’s image, but we are not God. Whether humans use CRISPR in a constructive way or in a potentially destructive way will be answered by the moral and religious belief systems of those who decide how this new technique will be used. An interesting article on this subject is in the March 2017, issue of Christianity Today, pages 49-51.

Music of the Spheres

Around 500 B.C. there lived a famous Greek philosopher by the name of Pythagoras. He gained a sect of followers in a place called Crotone in southern Italy. The Pythagoreans taught that the planets (including an Anti-Earth on the other side of the Sun), the Moon, and the Sun were fastened to great spheres of crystal, rotating around a central fire. They believed that the motion of these spheres created an exquisite harmony which ordinary people cannot hear. Pythagoras and his followers believed they could tune instruments by mathematical calculations so the instruments would resonate with the spheres. Dancing to the music of the spheres was an activity that occupied much of the time of the ancient Pythagoreans.

Although the ideas of the Pythagoreans were not accurate in many ways, from a scientific standpoint, we can see the harmony of the spheres of stars and planets today. You could say that the music to which the spheres dance is loud and clear. Our solar system moves with definite rhythms, following a “musical score” written with incredible precision and purpose. As our knowledge and understanding has improved, the incredible complexity of the musical score has become obvious. Isaac Newton gave us the original score, and Albert Einstein fine-tuned it. Both gained their understandings by looking at the grand design. We have learned that the Moon helps to hold Earth at the proper tilt. We have seen that the large Jovian planets (Jupiter, Saturn, Uranus, and Neptune) help to shield Earth from intruding comets. We know that the very substances of which we are made had their origin in the stars.

Dean Overman in his book A Case Against Accident and Self-Organization showed the fallacy of trying to explain everything we see in the cosmos by chance. It has been suggested that a large number of monkeys typing on a large number of typewriters would eventually produce the complete works of William Shakespeare. Overman shows that the chance of monkeys typing a section from Macbeth containing only 379 letters would have a probability of 10 to the 536th power. When you consider that there are only 10 to the 80th power atoms in the known universe, you can see that the chances are very small. Mathematicians consider anything with a probability of 10 to the 50th power as a mathematical impossibility.

The dance of the spheres and the music to which it moves is nothing like what Pythagoras thought. It is much more complex. It is also very real, and it speaks to us in beautiful ways about our own design and purpose.

Mind as a Miraculous Healer

Mind as Healer
It is difficult to have discussions about the validity of Christianity without the question of miracles coming up. Some skeptics would flat-out deny that miracles happen today or that they have ever happened.

When you get into a discussion about biblical miracles, there is no physical way to verify what happened. You either accept that it happened by faith or you reject it the same way. Miracles that happen today are a different matter. The kind of miracles Jesus did don’t happen today. No one has verified that a person was raised from the dead. By the same token, there are numerous claims of healings by people that seem to be verified by family and/or friends.

A very useful article appeared in National Geographic (December 2016) titled “Mind over Matter.” The basic thrust of the article is that the brain can have chemical stimulation that is natural or artificial which can make a healing take place. Belief, even if it is false, can be a cause of healing. A Parkinson’s victim in a trial at Stanford was given what he believed was a surgery to alleviate Parkinson’s symptoms. The surgeons did nothing to him, but he believed they did and was “significantly improved.” His comment is “Whether it was placebo or some kind of a drug doesn’t matter to me.”

I have learned in my many years of talking to people about miracles they believe they were given, that it doesn’t do any good to try to discredit the miracle. The important questions are: “What was the cause of the miracle?” and “What we are going to do with the new life that has been given?” Healing can happen in many ways. Mental and spiritual parameters can make things happen that we might assume are of a supernatural nature, when they may be a product of the awesome way our minds, souls, and bodies were created by God.

Earth’s Oldest Fossils?

Stromatolites in Banff National Park, Canada
Stromatolites in Banff National Park, Canada

It’s always interesting to see how the media distorts scientific material to make it more sensational. The front page of USA Today for March 2, 2017, carried a headline saying: “3.8 Billion-year-old Bacteria May Be Earth’s Oldest Fossils.” The article goes on to state as fact: “The bacteria lived near hydrothermal vents…” There are so many issues here that it would take several pages to point them all out, but the interesting thing is the actual discovery. Stromatolites are layered structures that may be produced by algae or bacteria, and some are ancient deposits, although others are still being produced today. I have seen these formations in the Gunflint Chert in Minnesota near a cabin owned by my brother. Those formations are circular and contain a mineral called hematite, an iron mineral that may have been a part of the biology of microorganisms.

This new find is an iron carbonate rosette that is circular and contains hematite. There is some evidence that it was formed near an undersea thermal vent. Since we see life around sea-vents today, it might be assumed the formation is of biological origin. There are chemical, non-biological processes that can produce similar structures. The problem with this kind of media headline is that it gives a false impression of how science works and what has actually been found. It may be that these structures were biologically formed, and they may be 3.8 billion years old. The Bible doesn’t date or describe bacteria and how God formed the ecosystem that would support humans on planet Earth. This same process may even be going on elsewhere in the universe, but it will take exhaustive research to verify or deny whether this is ancient life.

Real science does not announce possibilities as fact. The exaggeration of scientific discoveries does a disservice to science and makes modern-day readers believe things as proven that are simply speculations. Stay tuned for what future study of these structures reveals as truth.

Tool Use and Animals

Baboon with Primitive Tool
Baboon with Primitive Tool

There was a time when human beings were defined as those individuals who fashion and use tools. When researchers showed that chimps could fashion sticks to pull ants out of their anthills, paleontologist and anthropologist Louis Leakey was quoted as saying, “We are either going to have to change our definition of ‘human’ or invite the chimps to send a representative to the United Nations.”

Recently it has been shown that Orangutans, after watching humans use canoes, borrowed the canoes to forage for aquatic plants using the same techniques the humans had used. Octopuses have been seen carrying coconut shells around with them and then using the shells as a shelter. Crows have been seen fashioning sticks to use as levers to pry the lids off of bottles. Several kinds of monkeys have been seen to use conchoidally shaped chert or flint as a cutting tool. I have a raccoon that pulls my bird feeder up hand over hand, hooks it on a nail that is sticking out of the support my feeder hangs on and proceeds to empty the feeder.

Dr. Robert Shumaker of the Indianapolis Zoo has an interesting article about tool use by animals in the “Explore” section of National Geographic for March 2017. He gives 22 different animal groups all of which use tools in one way or another. Some animals, like the chimps, can imitate tool use. We all know that dogs can learn. At least some animals can think, but some clearly others cannot learn or think. Archerfish, capture insects by shooting streams of water from their mouths to knock insects off of plants near the water. They compensate for refraction, and they do this even if they have never been around another archerfish. It is clearly built into their DNA and is not learned or thought out.

What defines humans is our spiritual nature, not our ability to think or reason or make tools. We are created in the image of God, and that is what makes us human.

Talking with the Dead

Man Meets Robot
Man Meets Robot

Researchers at the University of Minnesota say that they will soon be making voice simulations of someone so close to the actual person that they will “be able to accurately imitate those who have died.” The claim is that “we will be able to continue to interact with them as if they continued to live.” There is a test called the Turing Test which allows researchers to tell whether a response is from a human or a machine. Some of the simulations have passed the Turing test. In other words, you could be talking to a simulation of your father who died ten years ago, and you would not be able to tell that you were talking to a computer. Family history, mannerisms, voice inflections, patterns of choices can all be built into the computer simulation.

In an article by Muhammad Ahmad from the Minnesota department of computer science in Saturday Evening Post (March/April 2017 page 10), a shocking question was asked. The question was, “Would such a system have a soul?” Ahmad responded that his work would allow experiences OF a deceased person, not experiences WITH the deceased. Ahmad says that “in the future, you would still be able to spend time laughing and reminiscing with a simulation so similar to your loved one that it would be difficult to tell the two apart.

The things that make us truly human will never be possible in a simulation. A simulation can revisit a memory from the past. Past events, mannerisms, and patterns of choice can be built into the simulation. However, there will not be creative expression in art and music, spontaneous acts of worship, feelings of guilt and sympathy, and an agape type of love. I have spent hours watching videos of my wife of 49 years and my children as babies and toddlers and teenagers. It has been a rich experience. I have recordings of my deceased mother and of my kids’ school events. Those are good memories, but even better is having the comfort of knowing that God is now caring for my loved ones and that in the future there is the hope of something far better than the best memories I have of the past.

How Close Are We to a Nuclear Holocaust?

Nuclear Explosion
One thing that seems to never go away is the incredible stupidity of human beings. Every day we see people do things that not only don’t make sense but in many cases are clearly wrong. Scientific American (March 2017, page 10) has some data that shows just how close the world has come to annihilation due to the failures of humans to manage nuclear resources wisely.

The article states that both the United States and Russia have about 900 nukes ready to launch. In 1983 the Russian detection system said the U.S. missiles were on their way. A Russian military officer had a gut feeling that it was a false alarm, and didn’t push the button that would have plunged the world into a nuclear war. It turned out he was right. In 1979 a similar situation developed in the United States which activated ballistic missiles and nuclear bomber crews. Satellites could not verify the alert, so the retaliation was not ordered. It turned out that training software which had a simulation built in had found its way into the alert system. In 1974 during his impeachment proceedings, President Nixon said to reporters: “I can go into my office and pick up the telephone, and in 25 minutes 70 million people will be dead.” There were those who were worried that he would do just that.

The point of all this is that humans continue to allow materialism, nationalism, and personal power struggles to dominate the future of the planet. Albert Einstein is reported to have said, “If world war three is fought with nuclear weapons, world war four will be fought with clubs.” Given this, the importance of getting people to see the wisdom of Christ and His teachings of peace cannot be over-emphasized, In Matthew 24 Jesus predicted that future generations would do stupid things, “You will learn of wars and rumors of wars … famines, bogus religions” etc. Rather than be panicked by all this and what is happening to the world, we need to be encouraged to look to the time when God will put an end to all of the stupidity, and all of God’s children will be at peace with one another and with God. Matthew 24 describes that in some detail, and it is worth reading again in our age of foolish talk.
