The Gravitational Constant and Earth’s Mass

“How much does planet Earth weigh?” We can’t put the planet on a scale, and the correct question is, “What is Earth’s Mass?” The scientific literature tells us Earth’s mass is six ronnagrams. That is six followed by 27 zeros (6,000,000,000,000,000,000,000,000,000 g). Newton’s law of gravitation is expressed in the equation F=G(mm’/x²). The m and m’ are the masses of two objects, x is how far they are from each other, and G is the gravitational constant which makes the equation work. The value of G is 6.67430 x 10^-11, that is .0000000000667430.

Any two objects with mass will attract each other. For example, you and the Earth are attracting each other, and you are attracted to the person sitting next to you, such as your spouse or significant other. So why don’t you feel that attraction to each other? (Gravitationally, that is.) If you put your mass and the other person’s mass into that equation, you will find that the force is extremely small. However, if you were in outer space and floating isolated from any other mass, you and that person would be drawn together.

So what is the point? This design of the gravitational constant is an amazing display of God’s wisdom and intelligence. Earth’s mass is so large that you can feel its attraction for you. That prevents you from flying off into space while allowing all of life to have mobility on the planet’s surface. The attraction of gravity on all objects in space pulls them together, with the force depending on the mass of the objects. The matter clumps into meteoroids, asteroids, and comets if the mass is relatively small. Greater mass results in stars and planets, with gravity pulling them into spherical shapes. Gravity also keeps solar systems and galaxies from flying apart. The gravitational constant acting on mass allows the cleansing of debris from space and the continuing production of new astronomical bodies.

The value of the gravitational constant (G) allows the creation of the universe, the Milky Way galaxy, our solar system, and planet Earth. It is just one of many mathematical constants that must be just right to allow matter and life to exist. How did such numbers get chosen? Is this some cosmological accident, or is it the product of intelligence?

Atheists respond by suggesting there are an infinite number of universes with different constants. We just happen to be in the one that got everything right. Unfortunately, there is no way to test this multiverse theory scientifically. It is more like a religious idea that has no purpose except to avoid believing in the existence of an intelligent Creator.

The gravitational constant is only one of many constants that must be fine-tuned for the existence of life in any universe. We have no reason to believe there are other universes, but if there are, they would also have to be created. We believe God created our universe for a purpose. The Bible gives a purpose for human life and states clearly that the creation described in Genesis 1:1 was by a God who created with Wisdom, as we read in Proverbs 8:1, 22 -31.

The Most Mysterious Number in Physics

Many physical constants determine the structure of the universe. All of them have units or dimensions, such as the speed of light (c) or the gravity constant (G). That is, all of them except one. That one is the fine-structure constant represented by the Greek letter alpha (α). The fine-structure constant seems to be a random number with no units or dimensions, but it keeps showing up in physics calculations. It has been described as the most mysterious number in physics. American theoretical physicist Richard Feynman called it “a magic number that comes to us with no understanding by humans.”

Recognition of the fine-structure constant originated with German theoretical physicist Arnold Sommerfeld in 1916. Chemists can identify different elements in the lab by the spectral lines they emit or absorb when their electrons change energy levels. Astronomers analyze the spectral lines of stars to determine what elements they contain. Some spectral lines are split, showing a fine structure. To explain this, Sommerfeld introduced a new constant into his equations and called it the fine-structure constant. It has no units like the speed of light or other constants. It is just a number – a ratio.

The fine-structure constant shows the strength of the interaction between electrons and photons. It also shows up in many other ratios in physics. The value is approximately 0.007,297,352,569 or 1/137. Physicists consider it mysterious because they don’t know where it came from or why it has that value. They can’t explain why it exists at all. But if you are not a physicist, why should you care about the most mysterious number in physics?

If the fine-structure constant had any other value, life as we know it would not be possible. If you changed that number, you would change the universe. A different value for the fine-structure constant would change the size of atoms and alter chemistry and nuclear reactions. No stable matter, no life, and no intelligent beings would exist. We wouldn’t be here.

Richard Feynman wrote that “all good theoretical physicists put this number up on their wall and worry about it.” Apparently, they worry about where it came from and why it is what it is. Feynman further wrote, “You might say the ‘hand of God’ wrote that number, and ‘we don’t know how He pushed His pencil.”

Feynman was joking about the most mysterious number in physics, but we think it was written by the “hand of God.” We also believe “He pushed His pencil” so that He could create humans for a purpose. More on that tomorrow.

The Uniqueness of Planet Earth

One of the positive things about science is that its methodology allows change. When new data become available, theories are either supported or discarded, resulting in the constant evolution of what scientists believe to be true. This applies to our understanding of the uniqueness of planet Earth.

Experts from NASA’s Goddard Space Flight Centre have announced that a widespread assumption about life on other planets is not valid. Science has assumed that other stars similar to our Sun in size and type also have similar stability. The Sun has not changed significantly in brightness and temperature in the hundreds of years that scientists have been observing and measuring it. Recent measurements of similar stars show that three-quarters of them go through changes in both brightness and temperature.

Dr. Noah Tuchow of NASA says that the number of alien worlds that could contain life has been “vastly overestimated.” The planetary zone where water could exist as a liquid is known as the “Goldilocks Zone.” A planet would have to be orbiting a star with relatively constant heat output to be in such a zone. Planets that formed too close to be in the star’s habitable zone would have their water boiled away. Those that began beyond the habitable zone would have frozen water that would take a long time to melt. Either way, they would have a relatively short time to support life. This shows the uniqueness of planet Earth.

NASA has created a new label for planets that enter the habitable zone after their formation due to orbiting a changing star. They call it the “Belatedly Habitable Zone” (BHZ). Dr. Tuchow says, “A planet’s history dictates its current potential to host habitable conditions and life.”

Our point is the uniqueness of planet Earth, not whether it is the only place where life exists. However, if life exists elsewhere, God created it. Every discovery scientists make shows that Earth is an extraordinary place and our Sun is an exceptional star. Considering what we have learned about the cosmos, the statement of Psalms 19:1 is more meaningful today than when it was written thousands of years ago: “The heavens declare the glory of God, and the sky shows His handiwork. Day to day they utter speech, and night to night they show knowledge.”

Please go to our doesgodexist.org website to see a chart titled “Evidence for Design in the Universe,” listing 47 of the vast number of variables required for a life-sustaining planet. The constancy of the parent’s star adds one more limiting variable to what it takes to have a world able to support life.

Asking a Computer if God Exists

Years ago, I heard a joke that went something like this. Scientists developed a massively powerful computer that could answer any question. The researchers asked the computer, “How did the universe begin?” The computer whirred, lights flashed, and out popped this answer: “See Genesis 1:1.” That joke originated when computers filled a large room, had spinning reels of tape and flashing lights, and used punch cards. Now, computers are small, use keyboards and monitors, have voice recognition, and speak in many languages. Soon we may have quantum computers with capabilities only dreamed of today. Have you ever tried asking a computer if God exists?

A topic that has received much publicity in recent months is artificial intelligence (AI). As computers become more humanlike with their ability to speak and answer questions, we are coming to depend on them more and more. Knowledgeable people suggest that the growth of AI will dramatically affect business, medicine, and entertainment. Other areas expected to face major changes because of AI are work, war, and education.

Recently, I have seen articles concerning a new AI development that worries educators. It’s called ChatGPT. This app can do more than answer questions. It can write essays. A student with an assignment to write a 500-word essay on a subject can input the topic and let ChatGPT write the paper. I decided this would be a good opportunity for asking a computer if God exists.

Going back to that old story, I asked the computer, “How did the universe begin?” ChatGPT responded with a 237-word essay on the Big Bang that agreed with current scientific theories. It was nicely worded, grammatically correct, and would probably satisfy a school teacher. However, it didn’t fully answer the question, just as the Big Bang theory does not.

Then I asked ChatGPT to write an essay about proving the existence of God. The result was 430 words that read in part:

“One of the most commonly cited arguments for the existence of God is the cosmological argument. This argument states that the universe had a beginning, and that everything that begins to exist must have a cause. Therefore, it is reasoned that the universe must have been caused by something that exists outside of the universe, and that this cause is God. This argument is based on the principle of causality, which states that for every effect, there must be a cause.
Another argument for the existence of God is the teleological argument. This argument states that the universe is complex and ordered, with many intricate systems and processes that work together in harmony. This complexity and order is argued to be the result of an intelligent designer, which is God. The design argument is based on the idea that the universe is too complex and ordered to be the result of chance, and that it must have been created by an intelligent being.
A third argument that is often used to prove the existence of God is the moral argument. This argument states that humans have a moral sense, and that this moral sense must come from a higher being, which is God. The moral argument is based on the idea that moral laws and values cannot be explained by natural causes, but must be the result of an intelligent and moral being.
Some people argue that the existence of God can be known through personal experience, through faith. They believe that God can reveal himself in personal experiences, such as through prayer, meditation, or other spiritual practices. They argue that the existence of God is something that can be known through a personal relationship with God, and not something that can be proven through reason or science.”

That summarized the arguments for God’s existence. Then, however, I decided to make the question more direct by asking a computer if God exists. So I asked ChatGPT, “Does God exist?” The answer came back in 195 words that concluded with:

“Ultimately, the question of whether or not God exists is a matter of personal belief and faith. It is important for individuals to form their own opinions on the matter based on their own experiences, beliefs and personal understanding of the world.”

Since ChatGPT never referred me to Genesis 1:1, I decided to ask, “What do we learn from Genesis 1:1?” I received this response:

“It teaches that God is the creator of all things, including the heavens and the earth. Additionally, it implies that God’s creation of the universe was a purposeful and deliberate act, rather than the result of chance or natural processes.”

I certainly can’t argue with that. I conclude that asking a computer if God exists will never result in a definitive answer to the question. Each of us must reach our own conclusion based on examining the evidence with an open mind.

The Theory of Everything

Perhaps the most sought-after quest in physics today is what scientists call the unified theory of everything. Physics researchers are pushing to discover a uniting concept that would combine all the forces in the universe into one equation and one understanding.

For most of us, this goal seems useless, but every new understanding of the forces in the natural world has led to good things for humanity. For example, Newton’s laws of gravity and mechanics led to the industrial revolution, which raised the standard of living for everyone on the planet. Maxwell and Faraday discovered the laws of electricity and magnetism, which gave us all the conveniences electricity provides. Heisenberg and Schrodinger discovered the quantum laws which led to lasers, transistors, computers, and the internet.

As modern researchers explore the details of all these theories looking for the theory of everything, it becomes increasingly apparent that they all come from the same source. There is a single relationship that connects all of the forces in the creation. Understanding the design of each of those forces brings us new applications to improve our lives in the future.

Dr. Michio Kaku has been a leader in this quest to find the theory of everything, and his latest book is titled, The God Equation. It is striking that these new understandings are very compatible with the biblical concept of God. The Bible portrays God as outside of time and space. His properties include being in a different dimension from the creation and the single source of all things. While the media popularizes string theory and time travel, they are the products of a vivid imagination. The real application of the unified theory of everything is the fact that there is a single source to all we see and experience, and that single source is God.

Science and faith always agree and support each other. It is human limitations that stop us from advancing scientifically and spiritually. How one comes to faith in God varies from person to person, but the teachings of Jesus Christ are easily understood and lead us to faith in the one Source of everything now and for eternity – God.

Potential Life-Supporting Planets are Hard to Find

Astronomers have discovered over 5,000 exoplanets in the last 30 years, and 2022 was a banner year. Exoplanets are planets orbiting stars other than our Sun. Astronomers are looking for potential life-supporting planets similar to Earth but orbiting another star like our Sun.

If you are going to find life in space, it would have to be on a planet with surface water and an atmosphere that provides oxidation and protects the surface from radiation and meteorite bombardment. Unfortunately, potential life-supporting planets are hard to find. Here is the breakdown of exoplanet characteristics so far:

*30% of all exoplanets are gas giants like Jupiter or Saturn.
*35% are like Neptune or Uranus, with densities so low that no life form could exist and no surface features that could sustain life.
*31% of all exoplanets are called super-earths which may have rocky surfaces but are too massive to support the chemicals needed for life. They lie somewhere between the mass of Earth and the mass of Neptune.
*Only 4% of all exoplanets are considered to be terrestrial, like Earth. However, many of them orbit the wrong kind of star, have no magnetic field, or have other properties that would be hostile to any life form.

The bottom line is that the study of exoplanets has shown the exceptional qualities of our planet and solar system. We must take care of planet Earth because we have no other potential life-supporting planets to migrate to if we make this planet hostile to life. God designed not only the life on our planet but also the conditions that allow that life to exist.

There are many possible explanations for why exoplanets exist. For example, they may be debris from the construction of our universe or the preparation for other life forms in the distant future. The message of exoplanets is that our planet is unique. The statement “The heavens declare the glory of God; and the skies show the work of His hands” takes on a special meaning in the light of what we see in space.

The Appearance of Design

Look around, and you will see amazing things in the natural world that give the appearance of design. Atheist evolutionary biologist Richard Dawkins has said that biology is the study of things that give the appearance of having been designed. But, of course, he does not believe they were designed because he does not believe in a designer. Is he correct, or is there a better explanation for the appearance of design? Here are some links to past articles in which we have dealt with that topic:

The Problem of Beauty

Is Design in Nature an Illusion?

Designing a Planet to Support Life

Marvels of Engineering in Nature

Designed with Purpose and Beauty

What Design Looks Like

Does Intelligent Design Destroy Science?

Those are just a few of the past articles on design that show evidence for a Designer. We believe that God has given us two revelations of Himself. One is His creation, and the other is His written word. The authority of the Bible is another subject we have dealt with often. Tomorrow, we will share some links from past articles on that topic.

The Age of the Earth

Yesterday, we looked back at what we have said about dinosaurs. Of course, that topic always leads to questions about the age of the Earth. Some insist that the Bible tells us that the planet is 6,000 years old, or at least not more than 10,000 years. Does it really say that? Here are some links to where we have discussed this before:

When considering the age of the Earth, we invite you to go to DoesGodExist.tv and scroll down to video #28, “The Age of Things.”

A helpful booklet on this topic is “GOD’S REVELATION IN HIS ROCKS AND HIS WORD.” It is available to read on DoesGodExist.org.

Those are some of the materials we have produced dealing with the age of our planet and God’s creative process to make Earth the perfect home for advanced human civilization and for working out His plan to defeat evil. Tomorrow, we will consider evolution.

Alien Minerals and Alien Life

Andrew Locock at the University of Alberta discovered two new minerals in a fragment of the El Ali meteorite that landed in Somalia. These minerals had never been found naturally on Earth, although scientists had synthesized them in a lab. Chris Herd, an Earth and Atmospheric Sciences professor and curator of the University of Alberta’s meteorite collection, named the two alien minerals “Elaliite” and “Elkinstantonite.”

The tabloids try to use this find to suggest that alien worlds exist that are radically different from Earth. The fact is that these minerals contain the common elements iron, potassium, and oxygen. Like many other “alien minerals” such as Brianite, Xifengite, and Heamanite, scientists have synthesized them. Inorganic materials can form new chemical configurations when they are subjected to temperatures and pressures not seen on Earth’s surface. All of these minerals with unfamiliar names are the product of conditions not present on the surface of our planet.

There are chemical restraints on what elements can sustain life. Biologists tell us that life is “that form that can move, breathe. respond to outside stimuli, and reproduce.” The elements that make those functions possible are carbon, hydrogen, oxygen, and nitrogen. For example, living things made of iron are not chemically possible, yet iron is the dominant element in meteorites. Oxygen is the one oxidizing element that allows respiration without adverse chemical reactions that would prevent life from surviving. For that reason, life forms breathing chlorine or bromine are not possible.

At the same time, alien minerals in meteorites do not mean that alien life is impossible. On the contrary, if there is life in space, it will be made of the same elements that we are. It may not look like us or live as we do, but we will not have any trouble identifying it as life.

Every time this issue comes up, it reminds me of my experience on a radio show. I was in Washington, D.C., doing a call-in talk show with Larry King (before he became famous) and a local atheist. We had a lively discussion about science and faith with some references to alien life. A caller said to the atheist, “What would you do if a spaceship landed on the White House Lawn and a little green man jumped out with a Bible in his hand and said, ‘Has Jesus been here yet?’” Before I could point out some problems with that proposal, my atheist opponent looked at me, smiled, and said, “Punt.” Larry King responded by going to a commercial.

How Fast Are You Moving?

If I asked, “How fast are you moving?” you might reply that you are sitting still. However, don’t forget that you are sitting on a planet that is spinning on its axis. A fixed observer in space would say that you are moving with the planet’s rotation at up to 1000 miles per hour if you are close to the equator. At the same time, Earth is revolving around the Sun at roughly 66,000 miles per hour. The Sun is one of 100 billion stars rotating around a black hole at the core of the Milky Way galaxy at approximately 400,000 miles per hour. Meanwhile, the galaxy is moving through space at around 2,200,000 miles per hour. So, how fast are you moving when viewed from a fixed point in space?

The amazing thing about the creation is that each of these numbers is critical for our survival. The spin of the Earth on its axis distributes heat in a way that we are not frozen or burned up. The revolution around the Sun keeps us from being drawn into the Sun or slung into outer space and frozen. The movement of the Sun around the galactic core prevents the black hole at the center of our galaxy from sucking in the entire solar system and destroying it. The galaxy’s movement through space prevents it from being absorbed by another galaxy. The speeds are critically fine-tuned because there is no tolerance for error.

As astronomers look at other solar systems and galaxies, they see the speeds that allow us to exist are not that common in space. The simple statement of Psalms 19 that “the heavens declare the glory of God, and the sky above shows His handiwork” reminds us that we are not the product of an accident. The more we learn about the cosmos, the more obvious it becomes that our existence is a product of intelligent design.

The psalmist also reminds us of the astonishing fact that the Creator cares about us. “When I consider your heavens, the work of your fingers, the moon and stars which you have ordained, what is man, that you are mindful of him …” (Psalms 8:3-4). So how fast are you moving right now? Fast enough to exist and to know that there is a reason for that existence. Read Job 1 and 2 and Ephesians 3:9-11 and 6:12 to learn more about that reason.
