Probability of a Life-Supporting Exoplanet

Planet Earth and the Probability of a Life-Supporting Exoplanet

One of my favorite columnists is Bob Berman, who writes in Astronomy magazine. Mr, Berman is a science writer who doesn’t have an ax to grind and doesn’t stoop to ridicule or hostility toward Christianity or faith in general. In the September 2022 issue, he referred to recent articles hinting that astronomers have found exoplanets better suited for life than planet Earth and examines the probability of a life-supporting exoplanet.

Berman lists a few of Earth’s unusual features. He points out that a planet being at the proper distance from its star to allow liquid water to exist is not that difficult to achieve. If you get the appropriate distance from a fire, you can have just about any temperature you want. Five other cases that Berman mentions are not that easy.

They include…
1) …having a nearby moon that stabilizes the axial tilt over long periods.
2) …not having lethal surface radiation.
3) …not having overactive volcanoes.
4) …having atmospheric gases that are used and produced by living organisms.
5) …having the right temperature underground. On Earth, surface temperatures disappear at about six inches, and at 30 feet, temperatures don’t change no matter what happens at the surface.


These are only five of the unique qualities of our home planet. Each design feature appears reasonable, but the probability of a life-supporting exoplanet depends on more than a single feature. Many planets may have one or two of the required variables, but to sustain life, ALL of them must be in place. That means you would have to MULTIPLY the probability of each individual variable to find the odds for life, especially advanced life, to exist on a planet.

The bottom line is that the probability of a life-supporting exoplanet is vastly greater than the number of stars in the cosmos. This planet is unique because it was designed by God to sustain life. Wisdom’s words in Proverbs 8:22-36 eloquently describe the process that gave us this extraordinary planet. We need to thank God for what we have been given–and take care of it.

Planetary Atmospheric Pressure

Planetary Atmospheric Pressure

The media often overlook how many things have to be “right” for life to exist on a planet. Planetary atmospheric pressure is one factor.

By “life,” we mean the standard textbook definition of organisms that can move, breathe, respond to outside stimuli, and reproduce. The problem is that many conditions make other terrestrial planets (planets with hard surfaces) unlikely to harbor life. Life is even less likely on Jovian planets that are primarily gaseous. You can postulate balloon-like living organisms in Jupiter or Saturn’s atmosphere, but radiation and electrical problems make that unlikely as well.

Planetary atmospheric pressure depends on the weight of the gases above a planet’s surface. The air pressure on Earth’s surface is 14.696 pounds per square inch a sea level. That pressure allows water to exist as a liquid, and it will enable various gases to dissolve in the water. We all know what happens when you shake a bottle of carbonated beverage and then quickly remove the cap. The sudden drop in pressure causes an explosion as the dissolved carbon dioxide escapes from the liquid. For organisms to absorb oxygen dissolved in water, which fish do, the atmospheric pressure must be high enough for the oxygen to dissolve. The atmospheric pressure on the surface of Mars is .01 of the pressure on Earth. That means water on Mars would contain no oxygen or dissolved gases.

There has been discussion about finding water on the Moon or Mercury, but those atmospheric pressures are considerably lower than those on Mars. That means water would not be in a liquid state. On the other end of the pressure spectrum is Venus, where atmospheric pressure 92 times greater than on Earth. At that pressure, toxic gases would be dissolved in any water that existed on the planet.

Planetary atmospheric pressure is just one more variable that must be carefully and precisely chosen when constructing an environment that will support and sustain life. The creation is far more complicated than most of us realize. As we learn more, we must stand in awe of the God who created our planet.

What Is the Shape of Space?

What Is the Shape of Space?

A question that astronomers have been working on for years is, “What is the shape of space?” The latest technical tools have answered this question, and it has significant apologetic value for those of us who believe in God.

Let us try to understand the issue. There are three possible shapes to space. It can be elliptical, hyperbolic, or flat. A mathematician would express this in geometric terms using Euclid’s fifth postulate. You have probably forgotten the postulate, but it merely said that through a point, there could only be one line drawn parallel to a given line. The other choices would be that there could be no lines drawn parallel to a given line or that there could be any number of lines drawn parallel to a given line. The fifth postulate assumes that the universe is flat. This is true for all terrestrial purposes, so no one is throwing away the high school plane geometry textbooks.

So what is the shape of space? In an elliptical universe, all parallel lines would eventually meet. If you go far enough into outer space, you would eventually curve back to where you started. In other words, if you had perfect vision and a perfectly clear sky, you could see the back of your head by looking far enough out into space. Light would curve following the shape of space. We all know that a triangle has internal angles that add up to 180 degrees, but in an elliptical universe, the angles would add up to more than 180 degrees.

In a hyperbolic universe, space would be saddle-shaped. Light going out into space would curve because of the curvature of space. But the curve would never close. It would just keep on curving. The sum of the angles of a triangle would be less than 180 degrees, and parallel lines would never meet no matter how far they go. They just curve away from each other.

New instruments can measure cosmic microwave background radiation with such accuracy that scientists can determine the shape of space. That is because the microwaves follow the shape of space. What is the shape of space? It turns out that space is flat or planar. The implications of this discovery are enormous. Since the universe is expanding, the creation is clearly not oscillating. It will not collapse back on itself and start over again as it would in an elliptical universe. In a planar or flat universe, there are no repeats. Physical reincarnation can never happen.

This also tells us that space is a created thing and not eternal. The universe was created with shape and with laws that apply in a flat universe following Euclid’s fifth postulate. Our studies in quantum mechanics are beginning to give us some indication that dimensions outside of space-time are the source for space and time as well as matter-energy. Genesis 1:1 rings more true than we ever imagined. The closer we get to understanding the creation, the closer we get to understanding the methods of the Creator.

All That Is Or Ever Was Or Ever Will Be

Cosmos - All That Is Or Ever Was Or Ever Will Be

“500 + amazing facts you need to know about galaxies, black holes, Einstein’s Relativity, the Big Bang, Dark Matter, and more!” Those are the words on the cover of Astronomy magazine’s special issue titled “Cosmos – Origin and Fate of the Universe.” The magazine has a great listing of discoveries made in the last decade, and it’s full of photographs, artwork, and a variety of charts. David Eicher, the magazine editor, opens the issue by quoting Carl Sagan’s famous line, “The cosmos is all that is or ever was or ever will be.” That is Sagan’s religious view, and Eicher plugs it by ending with, “We pack it all in here, and hope you will enjoy reading, and thinking about all that ever was, or ever will be.”

The magazine’s factual matter is impressive, but the philosophical and religious beliefs raise far more questions than they answer. The size of the cosmos has been a subject of intense study. Research shows that the number of galaxies in the cosmos is at least two-trillion –10 times greater than was previously thought. That amount of mass in the cosmos means that any explanation of how the creation happened is outside of current scientific understanding. It is becoming increasingly clear that only 4.9% of the universe is made of ordinary matter. The rest is mysterious dark matter (26.8%) and dark energy (68.3%).

The magazine presents the current scientific theory of the creation process with a “puffy giant dark star” made of weakly interacting massive particles (WIMPS). These WIMPS collided, annihilating each other and producing a halo of dark matter and black holes. This inadequate explanation makes it clear that the universe did not come into existence on its own. There was a beginning, and that beginning was caused. The cosmos is not self-existing. Those of us who believe in God would suggest that if these theories are correct, they are just God’s tools for creation. They may explain the methods He used, but it is clear that the cosmos we see is not all that is or ever was or ever will be.

This current scientific explanation of creation has implications for other scientific fields. For example, evolution depends on a religious belief called uniformitarianism, which says that no process has operated in the past that is not going on today. Much of what the magazine discusses is not going on today.

Two things are certain from this issue of Astronomy. We know little about the creation, and we deal poorly with what we do know. It’s evident that the cosmos is not all that is or ever was or ever will be. We suggest that a periodical like this one shouts again, “The heavens declare the glory of God; and the firmament shows His handiwork.” (Psalms 19:1).

Drake Equation and Planet Civilizations

Drake Equation author Frank Drake

In the long history of looking for life elsewhere in the cosmos, one of the exciting discoveries has been learning the things a planet needs to support life. In 1961, American astronomer Frank Drake proposed what is called the Drake Equation. He was looking for a way to calculate the number of inhabited planets in our galaxy with which communication might be possible. Drake’s equation lists seven parameters that would determine the answer to that question. They are:

1) The rate of formation of stars in our galaxy.

2) The fraction of those stars with planetary systems.

3) The number of planets per solar system with an environment suitable for life.

4) The fraction of suitable planets on which life actually appears.

5) The fraction of life-bearing planets on which intelligent life emerges.

6) The fraction of civilizations that develop a technology that releases detectable signs of their existence into space.

7) The length of time such civilizations release detectable signals into space.

If you knew each of these probabilities, you could calculate how many planets in our galaxy might be inhabited by intelligent beings with whom we could communicate. Drake gave each of these parameters a number or probability, but they were wild guesses. Once you have the numbers, all you need to do is multiply each of these variables by each other.

Let me explain. What are the odds of drawing the ace of spaces from a card deck twice in a row back to back? The odds of drawing one ace of spades out of a full deck is 1 out of 52 since there are 52 cards in a deck. To calculate the odds of doing that twice in a row would be 1 out of 52 times one out of 52. You multiply the individual probabilities, so the total probability would be one out of 2704. If you knew the likelihood of each parameter in the Drake equation, multiplying them together would give you the theoretical odds that we could receive radio communication from intelligent life on another planet in our galaxy.

Going back to the card analogy, if you drew one time out of a deck of 52 cards, the odds would be one out of 52. If you drew the ace of spades 52 times in a row, the number would be astronomical since you would multiply the result 52 times! The problem with the Drake equation is that the parameters are unknown and are probably unknowable.

There are also variables that the Drake equation didn’t include, such as the type of star. For example, a supermassive star will have a very short life expectancy. Researchers at Rice University reported in January of 2020 that many stars have extended magnetic fields which overlap the Goldilocks zones of most exoplanets. (As we have explained before, we say that a planet is in the Goldilocks zone when it can contain water in the liquid state). These strong magnetic fields will strip away any atmosphere the planet might have. Our Sun has a magnetic field, but it is not strong enough to strip electrons from atoms and molecules in the Goldilocks zone where Earth is located.

More variables regularly show up, and they tell us that our solar system and Sun have been carefully designed and formatted so that we can exist. Psalms 1:19 continues to take on new meaning with every discovery we make in space. “The heavens (do) declare the glory of God, and the firmament (does) show His handiwork.”

Frank Drake was involved in the founding of the Search for Extraterrestrial Intelligence (SETI), which we have discussed previously HERE and HERE and HERE.

Why Am I Here?

Why Am I Here? The editor of the October 2019 issue of Astronomy magazine begins the issue by reviewing the elements that make up our physical bodies and the current theory of how those elements are created in stars. He then asks the question, “Why am I here?” That is a question Astronomy magazine cannot answer and which the discipline of astronomy does not try to deal with.

What the science of astronomy does is give us a factual basis to know how the elements in our bodies were formulated. The editor points out that we have seven-octillion atoms in our body. (That is 10 to the 27th power or 7 billion billion billion atoms.) He reminds us that there are 60 different chemical elements in our body and he then says that that Big Bang nucleosynthesis produced those elements. So what is his answer to “Why am I here?” His answer is, “You’re here because atoms created in the Big Bang and in the bellies of stars have recombined in a way to make you billions of years after their creation – with a big thank you to your parents as well.”

What is interesting about this is that the editor doesn’t even try to answer the question he has posed. What he does is to give the current theory about HOW the materials that make up your body might have been formed. He does not answer the question, “WHY am I here?” The tragedy of modern thinking is that we have bought into substituting HOW for WHY. We see this in the media, in high school and college textbooks, and in magazines like Astronomy. The result is that humans are reduced to a product of physical change, and not a very attractive product at that. My atheist father wanted his physical remains to be returned to the earth from which it came “as quickly as possible.” His only hope for his life being significant was that his academic achievements would be remembered.

A good percentage of the Bible is dedicated to telling us why we are here. Numerous passages talk about Christians being “the light of the world.” The struggle between good and evil, between light and darkness, and between destructive forces and constructive forces is spelled out over and over again. (See Ephesians 3:10-11, 5:8-14 and 6:12-13; 1 Thessalonians 5:5-11; John 3:19-21 for examples.)

The result of finding the real answer to “Why am I here?” makes our lives full of purpose and value. It also causes us to regard every human being as having intrinsic, inherent worth. Knowing why I am here shapes my worldview and gives me purpose and meaning for existing. It’s a question worth finding the answer to.

Real Creation and Science

Real Creation and the Big Bang
In virtually all areas of science, one thing is always true. That is when we answer one question, we find many others. No area demonstrates this better than the subject of real creation.

By real creation, we mean an understanding of how the cosmos came into being out of nothing. What we are not talking about is the processes of biological change which is known as evolution. Darwinian evolution is not an alternative to creation because it is an entirely different subject. Darwinian evolution studies changes in biological systems which have already been created. It has nothing to do with the processes involved in creating the physical universe including time, space, and matter/energy.

There is massive evidence that the cosmos began in a singularity–a point of incredible temperature and density. We call that the “big bang” understanding, but science has no idea what banged or who banged it. We can describe with mathematics what happened between 10^-35 and 10^-32 seconds after that event. But quantum mechanics agrees with the biblical account that it was not a physical process which can be explained by classical physics. We can use classical physics to describe what continued the formation of the cosmos as we see it today. However, that is still not real creation because it only deals with changes in what was already created.

Astronomy magazine published an excellent article by William Jones in their February 2019 issue, page 68. Dr. Jones, a professor at Princeton University, gave a summary of how cosmologists approach the question of real creation:

“The answer is the combination of a big extrapolation and even bigger assumption based on a solid hunch and the surety of our ignorance regarding what is really going on. The truth is, everything about the early universe is speculative, and that is precisely why we study it.”

Dr. Jones then goes on to explain what our current guesses are and what we base them on. For those of us with a scientific interest and background, this kind of study helps us comprehend the nature and power of God. We hope to learn more about the processes involved in preparing a place for us creatures created in God’s image to exist as we transition to the dimension where it all started.

In addition to helping us comprehend God’s nature, these studies help us see the wisdom of God and His planning. Proverbs 8:22-32 brings us to understand wisdom’s role in real creation. Tomorrow we will take a look at the intricacies of making a star and placing it so that life can exist.

Our Unique Solar System

Our Unique Solar System
As astronomical equipment gets better, the details of stellar systems other than our own show patterns that highlight our unique solar system.

The January 3, 2018, issue of The Astronomical Journal published a report on a study of 909 planets in 355 systems discovered by the Kepler Telescope. The study shows two major patterns in neighboring exoplanets. The first is that those exoplanets tend to have similar masses. The second is that their orbits are regularly spaced from one planet to the next.

Our solar system has inner planets that have mismatched sizes, and they are widely spaced. All models of solar system formation fit what we see in exoplanets. The evidence suggests that exoplanetary systems have not been disturbed since their formation. Our system is different because it shows evidence that it has been disturbed. Jupiter and Saturn seem to be tools that modify the normal pattern of solar system formation.

In 1996 an extraterrestrial rock fragment was discovered in Egypt called the Hypatia stone. The mineral composition of that stone is unlike any other known object in our solar system. Scientists think that it originated outside of our system. Our solar system seems to be unique in both structure and chemical makeup. Astronomers are discovering indicators of how God created the Earth and all of the things that allow life to exist on it.

The design of our unique solar system compared to other systems helps us to understand that we are not a product of chance collisions or explosions in space. The simple statement of the Psalmist in Psalms 19:1 has a different frame of reference now than when it was written. It is truer today than when the ancient shepherd looked at his sky and wrote, “The heavens declare the glory of God and the Earth shows the work of His hands.”

Listening for E.T. Continues

Listening for E.T.
The media seems to be obsessed with the quest to find life in outer space. They are especially interested in a “Mr. Spock” type of life–human in appearance but with super powers. SETI (Search for Extra-Terrestrial Intelligence) has been going on now for almost 60 years. Billionaire Yuri Milner has committed $10 million dollars per year until 2025 to keep the SETI project listening for E.T.

We have pointed out many times that finding life in space would not invalidate Christianity or the Bible in any way. Humans seem to be dedicated to finding an alternative to God’s way as revealed in His Word. Many seem to believe that finding an advanced alien civilization would be such an alternative.

The September 2017, issue of Astronomy magazine, has an interesting article by associate editor John Wenz. The article on pages 34 and 35 is cleverly illustrated with cartoons by Theo Cobb. It shows 16 different “alien” cases that all turned out not to be messages from E.T. Wenz traces the misguided attempts to find alien signals from outer space that would indicate intelligent life out there wanting to interact with Earthlings. He goes back to 1960 when SETI’s first project called OZMA claimed to have received a signal from Epsilon Aurigae, a star about 2,000 light-years from Earth. The team, including Frank Drake who founded SETI, thought that they were receiving a signal from space, but it turned out to be terrestrial in origin.

Again, this is not an apologetic issue, but it does show the desire of humans to find a better existence. We would suggest the better existence comes from reading and understanding God’s Word, not from seeking alien help in straightening out the mess we have made. Those listening for E.T. may be waiting for another 60 years–or perhaps thousands.

Alien Claims and the Media

No Aliens Are Near
Every time some unusual signal from space is discovered, we see headlines in newspapers about aliens being the source of the signal. In August of 2016, reports came out of a radio telescope in Russia known as the RATAN-600 that had picked up a strong signal in the 11 gigahertz band. This was coming from a star known as HD 164595 and was first detected in 2013. Since that time the RATAN telescope and SETI have listened for repeat signals, but none have been detected. Headlines in the media have been things like “Baffling Alien Signal Detected.” Dr. Eric Korpela who works with SETI says, “There’s always the problem that scientific vocabulary is different from the public vocabulary. Detection, to me, means something was detected. To the public, it may translate as ‘We found aliens.’” It turns out that the signals have several possible natural explanations, none of which involve aliens.

The question remains as to why the public is so obsessed with the theme of aliens. We have pointed out repeatedly that finding life in space doesn’t have anything to do with the existence of God. If God chose to create life in other places for reasons we don’t fully understand, that is no issue. The Bible deals with humans and our existence on Earth. It is becoming obvious that there are no higher forms of life anywhere close to us, so the question is moot. This is not a question that has implications for the existence of God or the credibility of the Bible.

I have had atheists respond to me by saying that if life exists elsewhere, it proves that life can come about by chance. That assumes that God exists only on our planet, which is a misunderstanding of what God is. The fact remains that having a story about aliens sells, and video games and sci-fi movies will continue to propagate the idea. I have often told the story of doing a radio debate with an atheist on the Larry King talk show in Washington D.C. before he became famous. A listener called in and asked the atheist what he would 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?” My atheist friend responded “punt,” and maybe that’s what we should all do on this issue until we have more facts.
