X-Ray Vision and X-Ray Destruction

The fictional character Superman is supposed to have x-ray vision. That super-ability to see through objects is shown in the comics and movies as something coming out from his eyes. As everyone knows, vision doesn’t come out from our eyes. We see because of the light coming into our eyes.

X-rays are electromagnetic radiation similar to visible light, but at a higher energy level and shorter wavelength. Then why can’t we see x-rays? For one thing, our eyes use a lens to focus light on the retina. X-rays can’t be focused by the lens in our eyes, or even by glass lenses. X-rays are focused by using metal tubes to guide the rays because metal is one thing X-rays can’t penetrate.

However, x-rays can penetrate flesh and destroy the molecules by tearing them apart. Even if the lenses of our eyes could focus x-rays on the retina, the x-rays would destroy the retina. Medical and dental x-rays use low doses for short durations, so they don’t pose a health risk. Your body can easily repair the slight damage that occurs.

Another reason we can’t see x-rays is that we are not normally exposed to them, and that’s good news. On Earth, radioactive minerals and radon gas emit x-rays in small amounts. From space, the Sun, other stars, and black holes emit x-rays, but we are protected by our atmosphere. X-rays from space arrive at the upper part of our atmosphere called the ionosphere, where they are absorbed. If all of the x-rays reached Earth’s surface, they would destroy living things and eventually sterilize the planet. The ionosphere makes life on Earth possible.

We don’t think this is just another coincidence. We believe it’s part of the divine design of this planet. X-ray vision is only for comic-book characters and movies.

Self-Destruction Defense

How can an ant defend against a predator by blowing itself up? The worker ants of a species (Camponotus saundersi) that lives in Malaysia and Brunei use self-destruction defense. Let me explain.

These ants have two glands filled with toxic glue running the length of their bodies. When the ant seems to be losing its battle with a predator, it makes the ultimate sacrifice. By violently contracting its abdominal muscles, the ant ruptures its body. The explosion scatters sticky poison in all directions disabling the predator.

How can that benefit the ant? Obviously, that ant dies, but its action spares the rest of the colony from the predator. Humans sometimes sacrifice their own lives to save others. But, unlike humans, ants are not conscious of the fact that they are sacrificing themselves for their colony. How can we explain this by natural selection? Self-sacrificing ants would not reproduce to pass on that trait to their descendants. It must have been designed into the ants by the Master Designer of life.

These ants practice self-destruction defense even though they don’t understand the concept of self-sacrifice. However, I believe their Creator does. It’s expressed beautifully in the Bible. (See John 15:13 and John 3:16.)

Earth’s Atmospheric Design

One of the many things that make our planet uniquely well designed is the atmosphere. Our atmosphere has the right density to burn up the 10,000 plus meteors that speed into it every year. It’s also dense enough to scatter the cosmic rays and X-rays from space, so we are protected from this deadly radiation by our Earth’s atmospheric design.

Also very important, the atmosphere is thin enough to allow light to penetrate so plants can grow. It contains the proper mix of gasses for all living things to use. There is enough oxygen for us to breathe, but not enough to cause dangerous, uncontrolled combustion. It has the right amount of carbon dioxide to allow plants to live and give us the right amount of the “greenhouse effect.” This proper amount prevents too much heat from radiating off into space, keeping Earth at a temperature that promotes life.

The atmosphere is mostly nitrogen, which is relatively inert, but plants need it to grow. Because nitrogen is inert, it’s released to the soil by bacteria and certain plants, such as legumes or by lightning or tectonic activity. The atmosphere is topped off with a layer of ozone that absorbs ultraviolet energy from the Sun to keep us from being overexposed to the harmful effects of UV rays.

When we look at Earth’s atmospheric design and compare it to that of other planets, we realize that God has given us just what we need for life on this planet.

Blood Clotting Design

A couple of days ago, I accidentally sliced the tip of my finger with a sharp knife. It bled a lot for a while, but in a short time, the bleeding stopped. The bleeding probably helped cleanse any debris from the wound, but I didn’t want the bleeding to continue. If our blood did not clot, we could bleed to death from even a small injury. Blood clotting design, or coagulation, is a very complicated process that scientists have studied for years.

The process begins when a puncture to your skin injures a blood vessel exposing blood platelets to the collagen beyond the blood vessel’s lining. The platelets immediately bind to the collagen and each other, forming a temporary plug. This starts a whole series of complex chemical reactions involving proteins and enzymes called clotting factors.

A cascading series of a dozen steps must take place for coagulation to complete. The result is the creation of fibrin strands which strengthen the platelet plug and stop the bleeding. If any single factor of the clotting process is missing, the clot does not form, and the bleeding continues.

Hemophilia is a genetic defect that omits a clotting factor. It disrupts the process of blood clotting design such that people with hemophilia may bleed uncontrollably from even a small wound. This is an extremely simplified summary of the coagulation process involving a dozen factors requiring specific proteins and enzymes that must happen in a particular order. For more details, click HERE.

Without blood clotting, humans and other mammals could not have survived. All of the clotting factors had to be present at the beginning of mammal and human life, meaning that the coagulation process could not develop gradually by chance. The fact that our blood clots when we are injured is another evidence of design by an intelligent Creator.

Advantages of Cold Blood

Ectotherms are animals that are often described as “cold-blooded.” This group includes amphibians (such as frogs) and reptiles (such as snakes). These animals absorb heat from their surrounding environment instead of generating it internally from the food they eat. For that reason, they don’t need as much food to survive as a “warm-blooded” (endotherm) mammal or bird needs. That is one of the advantages of cold blood.

The food required for one mammal could feed 20 reptiles of the same size. So when food is in short supply, reptiles can survive when mammals may not be able to. Another advantage for ectotherms is that when the weather is cold, and food is scarce, they become inactive and don’t need to eat. This design allows for the efficient use of natural resources.

Also, ectotherms generally lay eggs and allow their young to hatch and survive on their own. The young can get their own food and even defend themselves. When temperatures are lower, frogs produce a larger number of females, and when it’s warmer, there are more males. This design considers the fact that cold weather makes the survival of the young less likely, so the larger number of females to lay eggs keeps the population steady. When survival is more likely because of warmer weather, not as many females are needed.

Without this system and the advantages of cold blood, the populations would vary widely. Cold-blooded animals are well designed to conserve resources and maintain the balance in nature. Design suggests a Designer.

Fermi Paradox – Where Is Everybody?

There are billions of stars in the galaxy, so there must be billions of planets in the galaxy. For many years people have speculated that there must be intelligent life out there and even civilizations that have developed space travel. In a casual conversation among scientists in 1950, physicist Enrico Fermi asked, “If these civilizations do exist, where is everybody?” That question came to be known as the Fermi Paradox, and it led to the picture, which we will explain.

The Fermi Paradox points out the lack of any evidence for what many see as a high probability of intelligent life elsewhere in the galaxy. Since no space aliens have landed on Earth and announced their arrival, some scientists decided to search for them by electromagnetic radiation. In 1960 astronomer Frank Drake began a coordinated project which became known as the Search for Extraterrestrial Intelligence (SETI). Ever since then, millions (or billions) of dollars and millions of hours have been spent listening for any transmission of any intelligent beings on other planets. The results have been zero. Where is everybody?

In 1995 the SETI Institute established Project Phoenix, which concentrated only on the 800 closest stars and their planets. Working from 1995 until 2004, the project concluded that there is no species as technologically advanced as humans in the universe within 200 light-years of Earth.

Because of the laws of physics and the dangers of space, any space traveler would be limited to no more than one percent of the speed of light. (Exceeding, or even approaching the speed of light is only possible in the movies.) So traveling at maximum speed from the nearest possible location, a space alien would need 20,000 years to reach the Earth. You could add to that another 5,000 years to dodge space objects (including stars, planets, and asteroids) on the trip. So for a space alien to reach Earth would take at least 25,000 years, and probably much longer.

So what is the picture? It’s a digital representation of what is called the Arecibo message. In 1974, scientists sent out a radio message from the Arecibo radio telescope in Puerto Rico. They aimed it a star cluster called M13, which is 25,000 light-years away. If there is any intelligent life there able to receive and decode it, the message tells about planet Earth and humanity. (You can find the “decode” HERE.) Of course, if there are any intelligent beings in M13 wondering “where is everybody,” they should receive the message in 25,000 years.

The Fermi Paradox is still unsolved. As the leader of Project Phoenix, Peter Backus, said, “We live in a quiet neighborhood.” God, on the other hand, being unlimited by time and space (remember that He created time/space and matter/energy) is always near and ready to hear our prayers unless we are unwilling to acknowledge His existence.

Magic Potions from the Periodic Table?

Imagine that you are walking along an unfamiliar street, and you see a sign that says, “Magic Potions from the Periodic Table.” The unusual sign and the look of the store arouse your curiosity.

As you walk in, you notice that the room is dark, and you see a man who looks like the stereotype of a wizard. On shelves lining the walls, there are 92 bottles of chemicals. You see labels on some of them that say “carbon,” “oxygen,” “nitrogen,” “phosphorous,” “zinc,” and other elements. The “wizard” is pouring some chemicals from bottles into some beakers. He looks at you with a smile and says, “What can I mix for you today? I can give you a potion for morality. How about something to make you appreciate beauty? Love—the true, unconditional kind of love is right here. How about letting me mix you up some meaning and purpose in life?”

You are startled and a bit confused because you had chemistry class in school. You realize that putting together the chemical elements you see on the shelves will not give you the things this “wizard” is offering. Even carbon-based molecules cannot supply morality, appreciation of beauty, true unselfish love, or meaning and purpose in life.

Chemistry is not enough. There is something beyond the chemical formulas and covalent bonding that comes into play in humans. The “wizard” is the naturalist who says that chance evolution and chemistry explain everything about our existence. Do we accept his suggestion? Does chemistry explain it all? Can the wizard’s magic potions from the periodic table fully explain what it means to be human?

Shouldn’t we look for an explanation beyond naturalism? We think a better explanation is that there is a God who created us in His image. It seems evident that we are more than bodies made of chemicals assembled by chance.

God Cannot Exist Because…

One of the objections that we hear most often is, “God cannot exist because a good God would not allow evil and suffering in the world.” The argument is that if God is good and all-powerful, He would not allow evil, pain, and suffering. Either God is not good, or He is not powerful, or, most likely, there is no God.

Those who advance this objection are saying that their knowledge of all things proves that they know what God should do. God could not possibly have a good reason for allowing things to run their course based on circumstances and the actions of people. God should intervene to stop people from doing anything that would cause harmful consequences for themselves or others. God should cancel the natural laws at times to prevent accidents and disasters. People who make these arguments are claiming to be smarter than God.

But what if God is smarter than we are? What if God knows more than we know? Suppose that God knows the future because He is not limited by our time dimension. Is it possible that God has a reason for allowing bad things to happen that we, in our limited knowledge, cannot understand? Just because we can’t see a reason for God not to intervene, does that mean God could not have a purpose?

It’s a mistake for anyone to assume that a God beyond our limitations of knowledge and understanding could not exist. A god with our limited knowledge would not be God. George Burns played the role of “god” in the 1977 movie Oh, God! When the character played by John Denver asked him what was going to happen, Burns replied, “How should I know?” When asked for clarification, his response was, “I only know what is. Also, I’m very big on what was. Now, what isn’t yet? I haven’t got a clue.” That describes the limitation of humans—not God.

The Bible tells us that God is not only good (“God is love”) and omnipotent (all-powerful), He is also omniscient (all-knowing). It’s a mistake to say, “God cannot exist because a good God would not allow evil.” The only way you could know that God has no reason to allow evil and suffering in this world is for your knowledge and understanding to be greater than God’s. To believe that is indeed the height of arrogance.

Magnetotactic Bacteria Finding Their Way

Before GPS, people found their way with a compass. Many still do. Did you know that finding your way is possible, even if you don’t have any eyes or ears, or even a brain, as long as you have a compass? Magnetotactic bacteria (MTB) use the magnetic field of planet Earth to know which way to go. To do that, they have to build a compass. Realize that these are single-cell organisms that live in marine or freshwater habitats.

Inside the cells of all living things, there are subunits called organelles that perform various functions. MTB have organelles called magnetosomes that contain magnetic crystals. They build the magnetosomes by digesting iron and combining the iron with sulfur to form iron sulfide or with oxygen to form iron oxide. The iron oxide is also known as magnetite, and it’s a powerful magnet.

The bacteria form chains of these magnetic crystals inside their cells. The magnetosome chain acts as a compass needle aligning the MTB to Earth’s magnetic field. In this way, the magnetotactic bacteria can “know” the direction to move. Why do these bacteria need to know directions? They are anaerobic bacteria, meaning that they survive without oxygen. Oxygen can be deadly to them, so they need to find an area away from it. Rather than blindly going around in circles looking for a safe place, they move in a straight line to their anaerobic safe zone.

In 1963, an Italian scientist first noticed certain bacteria aligning and moving in the direction of the north pole. It wasn’t until 2007 that scientists paid much attention to that observation. Without eyes, ears, or a brain, magnetotactic bacteria can find where they need to go. But without a brain, how can they know to do this? And how can a single-cell bacterium build the magnetosome organelles? These magnetic crystals are difficult for humans to create in a laboratory. In fact, scientists have found that the magnetite produced by bacteria is better for some applications than what the scientists can produce in the laboratory. For that reason, they are looking to find a way to mass-produce MTB to obtain their magnetosomes.

Who taught the magnetotactic bacteria this fantastic skill? Did one of them figure it out and then pass that knowledge on to future generations? We don’t think so. A better explanation is that the Master Designer programmed the skill into them.

You can read a scientific paper on MTB at THIS LINK. Leading evolutionary biologist J.B.S. Haldane (1892-1964) once said that if you could find a magnetic mechanism as part of a living organism, it would disprove evolution. You can read more about Haldane and his statement at THIS LINK.

Creating Life in the Laboratory

A graduate student named Stanley Miller at the University of Chicago conducted an experiment in 1952, and it became news headlines in 1953. The news reports suggested that scientists were creating life in the laboratory. That was a bit of an exaggeration, or what might be called “fake news.”

The Miller-Urey Experiment, as it came to be known, was intended to show that life could arise spontaneously from non-living chemicals. In a sealed system, Miller attempted to duplicate what was then thought to be the composition of the early Earth’s atmosphere. An electric spark discharge inside the system resulted in the formation of some amino acids. Amino acids link together to form proteins, which are the building blocks of life.

Scientists thought they had made a breakthrough to show how life began, but amino acids are a long way from living cells. Since then, science has found many problems with the Miller-Urey Experiment. One of them is that the gases inside the device were nothing like the early Earth’s atmosphere. Probably the biggest roadblock to life creating itself (abiogenesis) is that amino acids have two geometric configurations, known as right-handed and left-handed. To combine into proteins, all of the amino acids must be left-handed. Amino acids in nature are a mixture, and there is no natural source for all left-handed amino acids. Besides that, all DNA and RNA molecules are connected by sugars that must all be right-handed. Natural sugars exist in mixtures of right- and left-handedness.

Since the 1952 experiment, scientists have continued working hard to solve the question of how life could emerge spontaneously. The solution has only gotten more complicated as they have learned more about the amazing design in every living cell. In 2007, an Associated Press news release said, “Scientists Believe Artificial Life Will Be Possible in 3 to 10 Years.” Sensational headlines sell, but the news reporters don’t know what the scientists know.

It has been 68 years since the Miller-Urey experiment, and the goal of creating life in the laboratory is still a dream. Perhaps, someday scientists will achieve that goal. What will they have proved? They will NOT have shown that life can emerge from non-life on its own. They will have demonstrated that great intelligence with the proper resources can create life. That is what the Bible has been telling us for thousands of years.
