Average Star? – No Way!

Average Star? – No Way!
In the past, astronomers thought that the Sun was just an average star. After all, there are hotter stars, and there are colder stars. There are larger stars, and there are smaller stars than the Sun. If you plot the luminosity of all visible stars, the Sun falls near the middle of the system.

However, in recent years, it has become clear that the Sun is not an average star, but an extraordinary star. Without specific properties of our “oddball” star, life on Earth would not be possible. Here are just four of the many unique features of the Sun:

1-Most of the stars in the universe are binary or trinary stars. That means they are actually two, three, or even more stars orbiting each other although they appear to be a single star. A life-supporting planet could not survive that arrangement.

2-The Sun is relatively stable while most stars have much more violent flares that send out lethal radiation.

3-The Sun produces light in the proper wavelength to sustain life. Sunlight has the right wavelengths for photosynthesis and does not have the high-energy wavelengths of other stars.

4-Our Sun also has the right temperature and size to allow a large solar habitable zone where Earth can have an elliptical orbit and still support life.

There are many more “special” features that make our Sun more than an average star. If we didn’t have an above average star, we wouldn’t be here. We see our special star as another evidence that the Sun and our solar system is the work of a Master Designer.

Moon Mass and Life on Earth

Moon Mass and Life on Earth
Our Moon is different from any other moon in our solar system. And as far as we know, it’s different from any other moon orbiting any other planet in our galaxy. The difference has to do with the Moon mass.

No other planet has a moon with a mass that is so large compared to the mass of the planet. While other planets have multiple moons, our single Moon is large enough in relation to our planet that it stabilizes Earth’s rotational tilt at 23.5 degrees in relation to our orbit around the Sun. No other planet in our solar system has such a stable rotation axis tilt. The stable axis allows us to have stable and reliable seasons.

Seasonal changes distribute the Sun’s energy over Earth’s surface allowing plants to grow and food to be produced over a large area. Without the seasons, much of the Earth would be too cold, and some areas would be too hot for advanced life. The Moon has enough mass at the right distance from Earth to make advanced life possible on this planet.

In fact, the Moon has almost too much mass. If the Moon had two percent more mass, it would destabilize the Earth’s tilt. Is there a reason for the Moon to be more massive that it needs to be to stabilize the tilt? Yes, there is. The mass of the Moon creates a pull on the Earth known as tidal friction. That force creates the ocean’s tides which refresh the coastlines.

There is another reason for the large Moon mass. It also slows the Earth’s rotation. In the early Earth, days were shorter. The Moon has put the brakes on our planet’s rotation slowing it to a 24-hour day. Slowing the rotation has affected Earth’s weather, reducing temperature extremes and distributing rainfall more evenly around the Earth.

These are some of the many reasons we need the Moon at its exact size and location. Is it merely another coincidence that the Moon has just the right mass and distance from Earth? No, we believe God planned it that way.

Are We a Hologram?

Are We a Hologram?
This ministry has been functioning for 50 years, and one of the things we have seen is that atheist and skeptic arguments are cyclical. In the 1960s there was a push by skeptics to say that the physical world doesn’t exist at all and the universe is an illusion. So are we a hologram? Some scientists today seem to think so.

In the New York Times for May 10, 2018, science columnist Dennis Overbye wrote, “The news from some physicists like the late Stephen Hawking is that the universe might be a hologram, an illusion like the three-dimensional images on a bank card. Some cosmologists have argued that it is not inconsistent – at least mathematically – to imagine that the entire universe as we know it could just be a computer simulation as in The Matrix.”

Just because something is mathematically possible does not mean that it is true. You can prove that 1 = 2 if you make the right assumptions (in that case dividing something by zero). On a more practical level, there are certain things that holograms or illusions cannot do. For example, you can’t force an illusion to be taught to think. The whole notion of free will does not fit an illusion hypothesis. Our brains are not a simulation, and the things we do at a spiritual level are not within the reach of aliens.

If your view of the creation is that we are mindless pawns who have no purpose, then the hologram hypothesis may seem reasonable. Are we are a hologram controlled by aliens? For those of us who believe that we are spiritual beings with a purpose for our existence, this is just another silly, desperate attempt to get around being responsible for what we do.

NASA Turns 60

NASA Turns 60
In 1957 when I was 19 years old and a junior at Indiana University, the Soviet Union placed Sputnik, the first artificial satellite into orbit around the Earth. The following year the United States established the National Aeronautics and Space Administration with the goal of staking America’s claim to the cosmos. NASA turns 60 this year with an incredible record of accomplishment.

There have been 166 manned missions, 116 satellites which study the Earth, 70 missions to the moon and planets, 27 telescopes/observatories placed in space, and 17 satellites studying solar wind and interplanetary science. We now have robots making incredible discoveries at every turn, and plans are in the works for the first humans to land on another planet.

As a physics major and later as a physics teacher I have been enthralled with NASA’s accomplishments. I have had students who graduated from my high school and went on to have key roles in NASA. As those students come back and share their experiences and what they have discovered, I have been encouraged. I am excited by the fact that most of them see their discoveries, as I do, as a way of learning what God has done and understanding some of the methods He has used.

What an exciting time to be alive, and what a blessing it is to learn and grow in our faith and our knowledge! The more we know of the creation, the closer we get to the Creator. As NASA turns 60, I look forward to what lies ahead.

Fake Documentaries

Fake Documentaries
One of the frustrations of politics for us common folk is not knowing what is factual and what is fake. Any fact that a politician doesn’t want to hear can be labeled and discarded as “fake news.” The same problem exists on popular television in what we would call fake documentaries.

People seem to feel that if they see something on television called a documentary that it is true and has been verified by a reputable source. Religious groups, atheist groups, and food fad groups produce fake documentaries. They are also created by promoters of ESP, people who advocate alien visitations to Earth both now and in the past, and people who just want to make money with a fake documentary.

In the November issue of Astronomy magazine (page 64), Jeff Hester tells of being asked to comment on a bogus show about UFOs. The show was called a documentary and Hester, who is an astrophysicist, was interviewed as part of the program. The claims were totally false, and Hester said so in the interview and assumed the documentary would be scrapped.

The show was eventually broadcast as a documentary and given broad exposure. Hester called the producers and pointed out that he had shown that the story they were presenting was false. The producers admitted that they knew it was false. Then they stated something which Hester quoted in his column:

“Documentaries on stuff like this aren’t meant to educate people. They’re meant to sell soap. My job is to tell the intended audience exactly what it wants to hear. If people want to see miracles and space aliens, I show them miracles and space aliens. That way they tune in, watch to the end, leave happy, and buy the sponsors’ products.”

Remember that this was a television show called a documentary which many people will quote and believe. Yet the person who produced the fake documentary freely admits it was fake. Hester concludes “..they’re just plain old-fashioned carnival hucksters, picking the pockets of gullible people they play for rubes.”

We try very hard to quote scientific research from credible sources that can be verified. We also remind our readers that there are fake documentaries. We encourage you to think, and not believe something you see on television just because it is called a “documentary.”

Alone In the Milky Way

Alone In the Milky Way
Yesterday we mentioned an article by John Gribbin in Scientific American (September 2018, page 96 or online HERE.) The title of the article was “Are Humans Alone in the Milky Way?” Although Gribbin suggests that some form of life exists elsewhere in the galaxy, he insists there could be no sentient beings like ourselves. The reasons for concluding that we are alone in the Milky Way galaxy are these “amazing” and “implausible” “coincidences.”

SPECIAL TIMING. The elements that make up a terrestrial planet like Earth are produced from hydrogen and helium by thermonuclear fusion. We see supernova explosions producing the heavy metals that make up a terrestrial planet and life itself, but it takes time for this process to create the necessary elements. Most of the exoplanets we see have minimal amounts of the heavy elements because they are early in their stellar evolution. Even the sun itself is 71% hydrogen and 27% helium with only 2% metals. The timing of putting the materials together to make a terrestrial planet is critical.

LOCATION IN THE GALAXY. The location of a solar system in the galaxy makes a difference. The galactic habitable zone is the area where there is a freedom from the concentration of supernovae. Systems near the center of the galaxy have high levels of radiation in the form of X-rays and cosmic rays. There is a massive black hole in the center of our galaxy called Sagittarius A which produces massive amounts of radiation. Gamma-ray bursts occur in certain places in the galaxy. In our area of the galaxy, sterilizing radiation bursts do not happen.

Recent studies of the galactic habitable zone tell us that it extends from 23,000 to 30,000 light-years from the center or only about 7% of the galactic radius. This zone contains only about 5% of the stars, because stars tend to concentrate toward the core of the galaxy. Our Sun is close to the center of the galactic habitable zone providing rare long-term stability.

TYPE OF PLANET. So far astronomers have discovered about 50 “earth-like planets.” What that means is that they have found rocky planets in the habitable zone that are about the same size as Earth. Venus would qualify as an “Earth-like planet,” but it is an excellent example of how misleading that statement is. Venus has a thick crust with no sign of plate tectonics, no magnetic field, no way to recycle materials, and no stabilizing moon. Our Moon keeps the tilt of Earth’s axis at 23 ½ degrees providing a stable climate.

Realize that all of these factors are just to have a ball of rock in the right place at the right time with the right materials with which to make life. Now we would need to calculate the odds of getting the right chemicals together at the right time in the right place with the right catalyst to make the first living thing. Books have been written about how improbable those steps are. The writers are not religious fanatics, but scientists who are doing the research.

The Scientific American article, concludes that we are alone in the Milky Way:

“As we put everything together, what can we say? Is life likely to exist elsewhere in the galaxy? Almost certainly yes, given the speed with which it appeared on Earth. Is another technological civilization likely to exist today? Almost certainly no, given the chain of circumstances that led to our existence. These considerations suggest we are unique not just on our planet but in the whole Milky Way. And if our planet is so special, it becomes all the more important to preserve this unique world for ourselves, our descendants and the many creatures that call Earth home.”

We must make one additional point. If an intelligent Creator was involved in this process, the probability of a habitable Earth with life on it is 100%. Perhaps we are not really alone in the Milky Way because there is a God who cares about us. For those who might want to consider this option, we encourage you to watch program #6 of the video series available free on doesgodexist.tv.

Implausible Coincidences

Implausible Coincidences in the Milky Way
Our ministry has been in existence for 50 years this month. During that time we have presented a large number of evidences that the creation of Earth and life on Earth cannot be a product of chance. Our arguments have been statistical, starting with the basic rule that when you have many parameters, you can estimate the total probability by multiplying the odds of all the factors involved. That approach has not changed, but the number of parameters and the odds grows with new data and information. Implausible coincidences continue to compound.

In the past several years, astronomers have found thousands of planets orbiting other stars in the Milky Way. Skeptics point out that the probability of one of those planets harboring sentient beings like ourselves gets better with each new discovery. Scientific American (September 2018, page 96) published a good review of some of the factors that are involved. The article plainly states this:

“Optimism about the possibilities of intelligent extraterrestrial life ignores what we know about how humans came to exist. We are here because of a long chain of implausible coincidences – many, many, many things had to go right to result on the situation in which we find ourselves. This chain is so implausible, in fact, that there is good reason to conclude that humans most likely are the only technological civilization in the galaxy.”

That is an interesting conclusion. The article goes on to list the variables that point to that conclusion:

SPECIAL TIMING
LOCATION IN THE GALAXY
TYPE OF PLANET

Tomorrow, we will examine those “coincidences.” The article concludes by describing the improbable nature of advanced human life. However, it credits evolution for the creation of that life while showing how “implausible” and “amazing” it is. We believe a supernatural Intelligence was involved which we call God.

Does God Exist?

Does God Exist
Perhaps the most important question you will ever ask is, “Does God exist?” The answer you give to that question determines your purpose and outlook on life.

When we look at our universe, our galaxy, and our planet rich with life, we are looking at things that were designed for a purpose. Design gives evidence of a Designer. Purpose gives evidence of a reason for our existence. To believe that everything in the universe came into existence and achieved its present state by chance requires more faith than believing in an intelligent Creator God.

Fifty years ago this month a former atheist, John N. Clayton began the DOES GOD EXIST? project. John is a professional science teacher who came to believe in God as a result of his study in science. The project has continued for half-a-century through lectureships, seminars, publications; and, most recently, websites.

Three years ago, we began a Facebook page which reaches people all over the world with a daily reminder of the amazing design and purpose in the world. In January of 2017, we began daily postings on this website DoesGodExist.tody? About a year ago we started sending weekly emails to those who request to be on our email list. The emails are called “The Best of the Week from DOES GOD EXIST?” They feature links to the previous week’s most popular posts on our Facebook page and this website. This gives people who may not have time to read our posts every day a chance to see what others think are the six best posts from the previous week.

DOES GOD EXIST? is a non-profit program that never asks for money, although we gladly accept donations. This project has continued through the faithful support of many people who believe that God does exist and that Jesus Christ came as God in human flesh to open the way to a relationship with our Creator. If you like our daily Facebook postings, there is just one thing we ask–click the “share” button to share our posts with your friends. If you like our daily posts on this website, tell others about them. We also have other websites and a quarterly printed publication.

We want to continue to remind people daily that there is meaning and purpose in life because we were created by a God who loves us and put us here for a purpose.

Design In Nature

Design In Nature
When a person says that the mindless forces of evolution can easily explain everything that appears to be design in nature, you have to wonder if that person understands the principles of statistics.

From a statistical standpoint the more parameters that exist, the less likely it is that a desired final result will occur. The odds of a single coin flipped into the air and landing on heads is one in two or 1/2. What are the odds of five flipped coins landing heads up? That would be 1/2 multiplied by itself five times. The answer is one in thirty-two or 1/32. If you throw fifty coins up at the same time, the chance of all fifty showing heads is so small as to be considered impossible. (Multiply 1/2 fifty times.)

In nature, we see situations where the odds would be equivalent to throwing a million (or more) coins up and having them all land on heads. There is no way that an open-minded, thinking person can begin to entertain the idea that blind chance can explain such events.

Books and movies on nature often use a phrase like “nature planned…” or “evolution engineered…” or “genetic forces created…” some natural phenomenon. If you truly believe that the forces that created and designed the universe with our planet and everything on it are “mindless, blind, mechanistic chance,” then you can’t attach words that indicate wisdom, purpose, design, engineering, or creativity.

The design in nature is hard to miss. It has to be rooted in the mind of a Designer. Some things are just beyond what mere chance can do.

CLEVER Planets

CLEVER Planets Include Earth
We have often mentioned many of the conditions that must exist to make a planet habitable. The number is large and growing as science learns more about Earth’s special life-supporting features. Now NASA has awarded $7,700,000 to Rice University to conduct a five-year study to see what it takes to create a “recipe for a habitable planet.” The project has been named CLEVER Planets, an acronym for Cycles of Life-Essential Volatile Elements in Rocky Planets.

The award comes from NASA’s Nexus for Exoplanet System Science (NexSS). The research team will include experts in astrophysics, atmosphere and climate science, geology, geochemistry, geophysics, and organic chemistry. The investigators are from Rice University, NASA’s Johnson Space Center, the University of California-Davis, UCLA, and the University of Colorado-Boulder. This will be the most in-depth study of what it takes to create a habitable planet.

The lead investigator of CLEVER Planets, Rajdeep Dasgupta of Rice, wrote: “A recipe for life as we know it requires essential elements like carbon, oxygen, nitrogen, hydrogen, phosphorus, and sulfur.” Of course, that is not all that is required to create a recipe for a life-supporting planet. There are also many other conditions including liquid water, the right temperature with stable conditions, a proper atmosphere, and shielding from dangerous radiation. Having an atmosphere requires a planet of the right size to have the right amount of gravity to sustain an atmosphere. To have liquid water and the right temperature requires that the planet must be the right distance from the right kind and size of star. The planet needs a magnetic field to shield from dangerous particles coming from the star. To have a magnetic field, there must be magnetic elements inside the planet. The list goes on and on.

We look forward to seeing the results of the CLEVER Planets study five years from now. The bottom line is that it is very, very difficult to get all of the right ingredients required to create the recipe for a habitable planet. Earth is an exceptional place in the universe.

It seems doubtful that we will find any other planet similar to Earth. But as we have said before, if there is any form of life anywhere else in the universe, that has nothing to do with the existence of God. We believe in a God who can do anything He chooses to do in keeping with His nature.
