Billion-Dollar Picture

Billion-Dollar Picture
“A picture is worth a thousand words.” How often have you heard that phrase? It may very well be true, but this picture is worth more than that. What you see could be called a billion-dollar picture. At first glance, this picture may not look like much. However, you need to take a good look at the large white dot in the center. That’s us.

In September of 2016, the National Aeronautics and Space Administration (NASA) launched a spacecraft called OSIRIS-REx. The name stands for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer. Its purpose is to study asteroids. Specifically, it was launched to study a near-Earth asteroid named 101955 Bennu. It will not only study the asteroid, but if all goes as planned, it will take a sample from Bennu and return that sample to Earth. The total cost of the project will be about one billion dollars, but it’s much more than a billion-dollar picture.

On January 17, 2018, OSIRIS-REx turned its NavCam 1 camera toward Earth and snapped this picture. The spacecraft was almost 40 million miles (63.6 million km) from Earth and traveling away at 19,000 miles per hour (8.5 km per second). The largest and brightest spot in the picture is Earth. The smaller dot close to it is our Moon. The cluster of stars in the upper left is the Pleiades. In the top right is Hamal, the brightest star in the constellation Aries. Surrounding the Earth and Moon are five stars that are the head of the whale in the constellation Cetus.

OSIRIS-REx reached the vicinity of Bennu on December 3, 2018. It will be orbiting the asteroid and scanning the surface looking for a good place to land. That process will continue until July of 2020 when it will land and gather a sample. Scientists plan for OSIRIS-REx to deliver that sample to Earth in September of 2023.

Scientists hope that by studying the asteroid sample, they will learn more about the formation of our solar system. They hope to learn more about asteroids in general and what we might do to prevent one from slamming into our planet. There is also hope for mining useful minerals from asteroids and getting a better idea of the history of Earth. The whole list of scientific objectives for this space probe is contained in that long name for which we use the acronym OSIRIS-REx.

Forgetting about the cost and ambitious objectives, we enjoy looking at this view of Earth from far, far away. It reminds us of what a big solar system and universe we live in and how amazing is the God who designed it all. It also reminds us of the challenge God gave to Job about the Pleiades in Job 38:31-33. We encourage you to read God’s entire challenge in Job 38:1 to 40:2 as you look at this billion-dollar picture.

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.

Sun Stand Still

Sun Stand Still
Many times when a skeptic attacks a biblical story, the problem is caused by misunderstanding a word. In Joshua 10 there is an account of a battle between the Amorites and the Israelites. In verses 12 and 13 of the King James translation, Joshua said, “Sun stand still” and the Sun and Moon stood still for a whole day.

There is no question that God can make the Sun stand still. He can do anything He wants to do, but the physical consequences of stopping the Earth from rotating on its axis are enormous. The inertia of the water in the oceans, the effect on the atmosphere, and even the impact on the land masses challenge the imagination. A careful study of the words used in the biblical account resolves what appears to be an impossible statement in the scriptures.

The New Testament uses the Greek word “helios” which means Sun, but there is no Hebrew word for Sun in the Old Testament. In Genesis 1:16, the word for lights is “maor,” and the Sun is identified as “gadol maor” usually translated “greater light.” In Job 31:26, the Hebrew word is the shorter version “or” and Job 30:28 it is “chammah” referring to the heat of the Sun. In Judges 8:13 and 14:18 the word used is “cheres” again referring to the Sun’s burning heat.

In Joshua 10, the Hebrew word used is “shemesh” which refers to a ministrant, a device to minister to a need. It usually refers to the Sun but could be any ministrant. The word for Moon is “yareach” which refers to a wondering object. There is another interesting point about the words in the last part of Joshua 10:12. The pronouncement of God’s provision for the battle to continue says in the King James, “Sun stand thou still upon Gibeon (El-Jib today); and thou Moon in the valley of Ajalon.” Ajalon is in Dan and Gibeon is 4 miles from Bethel. These two locations are less than 30 miles apart. That fact should suggest that these are not the celestial Sun and Moon.

The question is not whether God caused a “great light” to allow the battle to continue at Joshua’s request, but what was the method by which God did it. There are many ways God could provide a great light or series of lights as a ministrant. Verse 11 speaks of “great stones from heaven” cast down on Azekah which was a town in Judah near Gibeon. Many astronomical possibilities to provide light are worth considering such as an asteroid or meteor shower or an aurora.

If you read the rest of the chapter, the main message is that God fought for Israel. Verse 14 indicates “there was no day like it before or after.” If you are satisfied with assuming that “Sun stand still” was simply a miracle of God and no explanation should be attempted, that is your prerogative. But to the skeptic, there needs to be an answer, and the evidence gives several possible answers that enable the believer “to be ready to give an answer to anyone who asks of the hope that is within us” (1 Peter 3:15).

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.

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.

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.

Hydrogen Wall and Creation

Hydrogen Wall and New Horizons
One of the interesting hints in the Genesis account is the suggestion that two creations were involved. A new scientific discovery of a hydrogen wall may also suggest that.

Genesis 1:1 uses the Hebrew word erets (earth) in describing the creation of the cosmos. “In the beginning God created the heavens and the earth.” That would suggest the simple idea that God created everything including all of the galaxies and whatever else exists in interstellar space.

In verses 9 and 10 the same word (erets) is used in a more restricted way: “And God said, ‘Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. And God called the dry land earth…” This second creation is what the creation week describes with humans and their domesticated animals as the focus of that week.

As the New Horizons spacecraft was leaving the solar system, it encountered what appears to be a hydrogen wall at the edge of our solar neighborhood. As our Sun moves through the galaxy it produces a stream of charged particles called a solar wind. This “wind” collides with uncharged hydrogen atoms producing a wall of hydrogen. This bubble or wall is about 100 times further from the Sun than the Earth is. The wall indicates that our planet and its solar system are isolated as a unit from the rest of the cosmos.

This new data on a possible hydrogen wall reinforces the biblical picture of God’s action during the creation week as a very special action on a very special planet. God created the cosmos, but then He set Earth apart as a place for those creatures created in His image. That is the primary message of Genesis.
