Messaging Extraterrestrial Intelligence (METI)

Messaging Extraterrestrial Intelligence
Since 1960, scientists have been using radio telescopes to search for signs of intelligent life in the universe. The program is called SETI (Search for Extraterrestrial Intelligence). So far it has been 57 years of listening without any positive results. Scientists have now entered the next phase of the search called Messaging Extraterrestrial Intelligence (METI).

On October 16-18, 2017, scientists beamed a message toward a red dwarf star known as GJ 273 in the hope that there might be someone there listening. Of course, there are always radio and TV signals of various kinds going out from transmitters all over the Earth, but this attempt is a concentrated signal beamed toward this specific system. The transmission contained mathematical and scientific information as well as music. The reason scientists chose GJ 273 is that there are two planets orbiting the star that they hope might be able to support life. And it is the closest possible potential life-supporting location.

Picking one random star to direct a communication signal toward may seem like shooting in the dark–and it is. However, a METI team member said that this is just a prototype of what they want to do “one hundred times, or one thousand times, or one million times.” In other words, this is just the beginning.

So when will the results of this experiment be in? GJ 273 is more than twelve light-years from Earth. So in about 2030, the signal will reach its destination. If there is intelligent life there listening and they respond right away, we might hear something by 2042 or 2043. Translation will be a challenge. If Messaging Extraterrestrial Intelligence continues to send out signals to other potential inhabitable planets, they will be farther away, and thus it will take longer to hear anything back.

Some scientists, such as Stephen Hawking, have criticized this effort because they are afraid it might wake up hostile extraterrestrial beings to the fact that we are here. Perhaps the aliens will not like our music style and decide that they want to put an end to it. They could send their “storm troopers” to start a Star Wars type of scenario. Of course, since they would not be able to travel at anything close to the speed of light (if Einstein is correct), they might arrive here centuries from now to find nobody left on this planet.

We have three observations on this project. First, all indications are that the chances of life existing anywhere in space are very slim. There are far too many variables needed to make life possible on any planet or moon. Secondly, the resources going into SETI and METI could better be used helping people right here on our own planet. Thirdly, as we have said before, whether or not life exists anywhere else in the universe has no bearing on whether God exists. God can create life anywhere He chooses.

When it comes to messaging extraterrestrial intelligence, we believe that there is Intelligence out there. We also believe that He would like to hear from us. We further believe that He has been to Earth to communicate with us. And we believe that if we choose to communicate with Him, we will not be limited to the speed of light. He can hear us instantaneously.

Doomsday Predictions Misguided

Doomsday Predictions
Just about every day you will see a headline in some periodical saying that the world will soon end in catastrophe. These doomsday predictions come from tabloids and church bulletins and always bring some kind of data to support them. Religious periodicals usually quote from Revelation and tabloids will take something out of context from a scientist or political figure.

The fact is that the major possible causes of global catastrophe do not come from periods of unusual natural activity. Earthquake numbers for the past ten years have been much smaller than 50 years ago. Hurricane frequency and intensity are not higher than in the past, although human mismanagement of shorelines has increased the damage even a small hurricane can produce.

The Sun is not becoming more active. The current cycle of solar activity is the lowest it has been in 100 years. In 1990 solar activity peaked at almost 300 sunspots. In the next maximum which happened in 2000, there were just over 200 sunspots. The last cycle which was in 2014, had 100 sunspots. In the December 2017 issue of Astronomy magazine, the lead article by Bruce Dorminey (page 20) is titled “Why Has the Sun Gone Quiet.” He suggests that the Sun will be relatively quiet for a long time.

In spite of the doomsday predictions, the biggest threat to our survival does not come from the natural world. God has designed a world that is remarkably stable. Earthquakes, hurricanes, and solar activity may cause problems, especially where humans have built vulnerable structures and removed natural safeguards, but our greatest danger is from each other. Our biggest problems come from humans refusing to do what Jesus told us would lead to our safety and security now and in eternally. You can read about it in the “Sermon on the Mount” recorded in Matthew chapters 5-7.

Life on Other Planets Doubtful

Life on Other Planets?
We have repeatedly pointed out that finding life on other planets has no bearing on the question of God’s creation of life on Earth. The Bible does not say that this is the only place where God created life.

Astronomers have observed over 3500 planets orbiting stars other than our Sun. Many writers have suggested that life in space is natural and likely because of the number of planets that exist. That assumption has a problem. There are an enormous number of variables that must be precisely controlled to allow life to exist.

Scientists have recently discovered that while it takes 243 days for Venus to rotate once, its atmosphere requires only four days in what is called “superrotation.” How can a planet’s atmosphere rotate 60 times faster than the planet itself? What effect does this have on the conditions at the surface of the planet where life could exist?

Another recent discovery concerns Proxima Centauri b, a planet orbiting in the habitable zone of the closest star to us other than the Sun. The star it orbits, Proxima Centauri, is continuously flaring and driving away any atmosphere that an orbiting planet might have. Astronomers working on the study of this star and the planets around it released a statement saying “any chance for life on Proxima Centauri b may be toast.”

We continue to find that the conditions needed for life on other planets are numerous. Having water is important, but many other factors must be carefully controlled for a planet to support even the most simple forms of life.

God’s creation of the Earth and the conditions that allow life to exist here becomes more and more amazing as we learn more about the cosmos.

Stretched Out Gravity Waves and the Nobel Prize

Stretched Out Gravity Waves
One of the interesting words in the Old Testament dealing with space and its creation is the Hebrew word natah–usually translated stretched out.

This word describes God’s act of creating space/time. Natah suggests that the cosmos is a like fabric that can be stretched. It could also mean stretching out as when we pull the cord of a lawnmower or outboard motor. (For uses of the word natah, see: Psalms 104:2; Isaiah 40:22; 44:24; 45:12; 51:13; Jeremiah 51:15; Zechariah 12:1)

Three United States scientists won the Nobel physics prize in October of 2017 by detecting ripples of gravitational waves traveling through the universe. In September of 2015, these scientists and others detected gravitational waves for the first time confirming a part of Einstein’s predictions.

The bottom line is that space is not empty, and objects in space are not isolated. The creation is like a garment that can have ripples in it. Stretched out gravitational waves fill the universe.

The next step for scientists will be to learn how to use gravity waves to study cosmic phenomena that they can’t observe by light or other electromagnetic radiation. Gravity waves will help us to learn more about God’s creation, and they are another verification of the biblical description of the nature of the cosmos.

NASA’s Creation Account

NASAs Creation Account
Each day NASA posts an interesting astronomy picture of the day at www.apod.nasa.gov. The picture for October 24, 2017, shows the periodic table of the elements. NASA captioned the picture with a summary of the current scientific theories about the formation of the elements of the periodic chart were formed. We call it NASA’s creation account.

It may be that some will want to simply say God did it by “speaking it into existence.” Of course, NASA does not mention God, but their summary does not in any way denigrate God or the way He works. This brief summary demonstrates the majesty and power required to form the creation. The fact that the process has no scientific explanation of an ultimate cause lends support to the statement, “The heavens declare the glory of God and the cosmos declares the work of His hands. Day after day they pour forth speech: night after night they display knowledge” (Psalms 19:1-2).

Here is the summary which you can read on NASA’s website:

“The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts or gravitational wave events. Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.”

We don’t see a conflict between NASA’s creation account and the one found in Genesis 1. The more we learn about the creation, the more we can say, “So that’s how God did it.”

Orionid Meteor Shower

Orionid Meteor Shower
The Orionid meteor shower has just passed its peak for 2017. The “shooting stars” that are visible in this annual event are not stars, but they are comet debris.

Halley’s comet (1P/Halley) passes within sight of Earth about every 75 to 76 years. Like all comets, it leaves behind a trail of small rocks that have fallen away. Every year at this time Earth’s rotation around the Sun causes us to pass through that trail of debris. Comet pieces are pulled in by Earth’s gravity, and they burn up because of friction with our atmosphere. We see the streaks across the sky, and since they seem to come from the direction of the Orion constellation, we call it the Orionid meteor shower.

Two years ago I was able to “catch a falling star” on camera. You can see the one I caught streaking downward from Orion’s left foot. In case you have trouble seeing Orion, the hunter, I have added labels to the second picture.

I think Orion is interesting because God talks about it in Job 38:31. God finally speaks in answer to Job and his friends, and God asks Job a bunch of questions that Job can’t answer. Among those questions, “Can you loose the cords of Orion? Can you bring forth the constellations in their season?” In other words, “Can you untie the belt of Orion?” Of course, Job could not. Nor could he do any of the other things in the questions God asked of him in chapters 38 and 39. Only God can.

The point God was trying to get across to Job is that God is in control and we need to trust Him, even when we can’t understand why things don’t go the way we think they should. Job finally understood that and said, “Surely I spoke of things I did not understand, things too wonderful for me to know” (Job 42:3).

There are events in the world and in my life that make me wonder why God allows those things to happen. Orion reminds me that I am not in control, but God is. Like Job, I have to realize that there are things I just don’t understand. The Orionid meteor shower is a yearly reminder of that.

Martian Global Aurora

Martian Global Aurora
On October 6 NASA’s daily space news website apod.nasa.gov contained pictures of a Martian global aurora. Because Mars has virtually no magnetic field, the radiation level goes sky high during solar storms. In the latest storm, radiation levels doubled–which would have been dangerous to life on Mars.

Earth’s magnetic field is very strong, and deflects radiation coming from the Sun. The radiation is deflected toward the poles, which is why we see the auroras near the poles. By deflecting the radiation, the magnetic field protects life on the Earth from dangerous levels. The more we learn about the cosmos, the more we see factors that make life possible on Earth. Our magnetic field is one more example of the design of our planet.

Looking for life in space is not just about whether there is water on a planet. There are a huge number of other factors that must be present. A strong magnetic field to shield from radiation is just one of those factors. Of course, an atmosphere suitable for life is also a requirement. NASA has a space probe called MAVEN (Mars Atmosphere and Volatile EvolutioN) orbiting Mars. The purpose is to find out if Mars lost its atmosphere due to not having a strong magnetic field.

The Martian global aurora is just one more reminder of the blessing of life on planet Earth. It also indicates that life on this planet is no accident.

Natural Elements of the Periodic Table

Natural Elements of the Periodic Table
One of the things high-school chemistry students have to learn is how to use a periodic table of the elements. As we worked with the chart, I almost always had a student ask me how the natural elements of the periodic table came into existence. Our textbook simply said that the elements were produced by “the event that produced the universe.”

Dr. Timothy C. Beers is the chair of astrophysics in the College of Science at the University of Notre Dame. The Notre Dame Magazine for Autumn 2017 contains an interesting article about his efforts to understand the processes that formed the natural elements of the periodic table. Dr. Beers calls it “Galactic Archaeology.”

Beers was the first scientist to identify “carbon-enhanced metal-poor stars.” These stars appear to have formed very early in the creation of the universe, and thus they give a window into the past. When the universe was created, only hydrogen and helium were present. Beers and his fellow researchers are working to understand what is called a rapid neutron-capture process. When neutrons bombard the lighter elements, some of those neutrons latch on and create heavier elements. As we watch that process taking place, we see that producing the elements heavier than hydrogen and helium requires a more complex process than anyone could imagine.

The Bible simply says, “In the beginning, God created the heavens (outer space) and the earth (elements that make up our planet).” God doesn’t tell us how He did it, but Genesis 2:3 tells us that God created (did a miraculous event that humans cannot do) and made (did an event that we can do and understand). The team that Dr. Beers leads is trying to understand how God did it.

Understanding how God created the stuff that makes up our bodies is a part of seeing the handiwork of God. Dr. Beers says, “I think human beings want to know the story,” and he says that his work will surely produce a religious response. The design of the natural elements of the periodic table is amazing. Learning how God formed them is a rich source of data about God’s design and creative wisdom.

In Proverbs 8:22-23 wisdom speaks of the creation, “The Lord possessed me in the beginning of His way, before His works of old. I was set up from everlasting, from the beginning, or ever the Earth was.” Knowing how God did the marvelous creation we see around us includes the very large such as the Grand Canyon and the very small such as quarks. Understanding how He made the elements is one of the most astounding evidences of design we can see in the cosmos.

More Viewers than the Super Bowl

More Viewers than the Super Bowl
The “Great American Eclipse” of 2017 had more viewers than the Super Bowl. According to Nielson ratings, the 2017 Super Bowl had 111 million viewers on TV. About 215 million adults, or 88 percent of the United States adult population, watched the eclipse. That total includes those who watched it live, plus TV and internet viewers. Of course, many children watched it too.

The University of Michigan and NASA compiled the viewing statistics with a joint survey. Sixty-one million adults in the United States watched the eclipse on TV, computers, tablets, or phones. Unlike the Super Bowl the vast majority, about 154 million, watched it directly with the aid of viewing glasses or pinhole cameras. About 20 million traveled to locations where they could see the totality. I can testify that the roads in southern Illinois were crowded with travelers. After the eclipse, it took 3 hours to drive 40 miles. You can watch a speeded-up view of the eclipse on this video. Be sure to turn the sound up so that you can hear the reaction of the people around me during the eclipse.

In addition to a large viewership, the satisfaction rate was high. Seven out of ten said they were not disappointed. (Probably about half of the Super Bowl crowd was disappointed because their team lost.) If you listen to the video that I edited, you can tell that the crowd on the bluff overlooking the Ohio River was not disappointed.

We are pleased that there was this much interest in a science-related event. God’s creation can draw more viewers than the Super Bowl.

Extraterrestrial Intelligence and God

Extraterrestrial Intelligence and God
Why do people want to believe in extraterrestrial intelligence (ETI), space aliens, and UFOs? It has been my experience that proponents of these things are people who reject Christianity and belief in the God of the Bible. Now there is scientific data which supports what my experience has indicated about extraterrestrial intelligence and God.

The scientific journal Motivation and Emotion published a study by North Dakota State University researchers showing that the more people believe in extraterrestrials, the less they believe in God. The researchers wrote, “ETI beliefs serve an existential function: the promotion of perceived meaning in life. In this way, we view belief in ETI as serving a function similar to religion without relying on the traditional religious doctrines that some people have deliberately rejected.” In other words, people believe in extraterrestrial intelligent beings to take the place of belief in God.

The research seems to indicate that believing in ETI provides a way to develop a view that gives meaning to life. The researchers say that belief in ETI “could make humans feel like they are part of a larger and more meaningful cosmic drama.” Even some scientists such as Nobel prize winner Francis Crick have advanced the idea that extraterrestrials planted life on Earth. It just goes to show that when you don’t believe in God, you will believe in anything. Atheist Michael Shermer who is the publisher of Skeptic magazine says “any sufficiently advanced extraterrestrial intelligence is indistinguishable from God” (Scientific American, January 2002).

All of this confusion about extraterrestrial intelligence and God is the result of an unfortunate, mistaken concept of what God is. It also results from not looking at all of the evidence for the existence of God. It does explain, however, why many people desperately try to find a way to believe that aliens are our creators.
