Earth’s Atmospheric Shield

Earth's Atmospheric Shield Protects Against Meteoroids
In 2013 a 10,000-ton 60-foot (20 m) wide asteroid entered the Earth’s atmospheric shield and exploded over Chelyabinsk, Russia. The explosion occurred 18 miles (29 km) above the Earth emitting a shock wave equivalent to 10 Hiroshima bombs.

A team led by Dr. Jay Melosh of Purdue University has extensively studied what controls how much damage a rock from space can cause. Dr. Melosh’s research was funded by NASA’s Office of Planetary Defense, and some interesting facts have come from the research. According to the study, Hollywood disaster movies aren’t even close to being realistic. Dr. Melosh says “Realistic stuff doesn’t make a good story. Hollywood usually manages to get it wrong.”

Meteoroids are hunks of rock that come in all shapes and sizes and with different amounts of porousness. As a rock enters the atmosphere, air pressure builds up in front of it, and a vacuum develops behind it. For most porous rocks, the air will rush into the rock and blow off pieces, like an air hose blowing in a bucket of sand. The design of the Earth’s atmosphere is what causes the break-up of the meteoroids. It is only if they are too big to blow apart that they hit the Earth leaving a crater such as Meteor Crater in Arizona.

The article about Dr. Melosh’s work in the Herald Bulletin says that Earth’s atmospheric shield is better than we thought. Modern astronomy continues to find design features of the universe and the Earth that allow life to exist on this planet. This is another example of a design feature that makes it so that we don’t have to walk around looking up to dodge an incoming celestial missile.

Flat Earth Movement Still Alive

Flat Earth
A Newsweek article for November 30, 2017, reported that more Americans scoured the internet looking for proof that the Earth is flat in the past 12 months than ever before. The first “Flat Earth International Conference” in September drew 500 “believers.” I put the word believers in quotes because there is no way to tell how many of these folks view the whole thing as a joke, and how many people truly believe in a flat Earth.

Atheist and popularizer of secular humanism Neil DeGrasse Tyson got into the act by “sharing a photoshopped image of the moon on Twitter to undermine Flat-Earthers.” The image shows what a lunar eclipse would look like with a flat Earth. Tyson frequently equates belief in God with the flat Earth mentality. We may shake our heads in wonderment at this whole scenario, but it brings to mind the old proverb, “If people don’t believe in something, they will believe anything.”

While the Bible doesn’t discuss this issue directly, there are passages like Isaiah 40:22, Proverbs 8:27, and Luke 17:30-35 which infer that the Earth is round with daytime and nighttime activities taking place simultaneously. Unfortunately, we see some Christians taking positions on scientific issues that are similar to the Flat-Earthers. When the Bible is put in the same arena with flat Earth believers the Bible’s credibility suffers.

You can intelligently and logically believe that “In the beginning God created the heaven and the earth.” There is massive evidence to support that statement. The same is not true of those who believe the Earth is flat.

Dark Energy and Creation

Dark Energy and Creation
One of the great mysteries of cosmology is the fact that the cosmos is speeding up as it expands. Scientists explain this acceleration by an invisible pressure called dark energy which makes up about 70% of the energy in the cosmos.

This explanation is based on an assumption called the Friedmann-Lemaitre-Robertson-Walker metric which took Einstein’s equations and applied them to a universe they assumed to be homogeneous and isotropic. In other words, it assumes a smooth universe. Science has determined that the universe is not smooth. It is made up of great voids separating networks of dense galaxy clusters and filaments.

Emily Conover writing in Science News for November 25, 2017, (page 22) said, “If the universe were soup, it would be more of a chunky minestrone than a silky smooth tomato bisque.” When the equations are applied to a universe that is not isotropic and homogeneous, the acceleration of the cosmos seems to be explained without the need for dark energy. By the very nature of the lumpy design of the cosmos, its collapse is avoided.

It is interesting to note that the cosmos was created in such a way that its very existence contains the fingerprint of a design that allows great stability over an infinite amount of time. The more we know of the creation, the closer we get to the Creator.

Many aspects of the creation we may never understand, but as our instruments get better and data accumulates, we understand that we have, in the words of Issac Newton, “found a pebble of knowledge while an ocean of truth lays before us.”

“In the beginning God created the heavens and the earth” is really all we need to know. Seeing His power, wisdom and design bolsters our faith in the fact that “The Lord possessed wisdom at the beginning of his work, before his deeds of old: wisdom was appointed from eternity from the beginning. Before the world began…” Proverbs 8:22-23.

Kepler-90: Our Twin Solar System?

Is Kepler-90 a Twin to Our Solar System?
It seems that every week astronomers make an announcement that the media use to suggest that the cosmos is overflowing with life similar to planet Earth. The latest system presented as identical to our solar system–and therefore harboring life–is around a star known as Kepler-90, 2545 light-years away.

Kepler-90 is made up of a parent star and eight planets, the same as ours. The star that serves as the sun for the Kepler system is a G type star, and our Sun is a G-2 star. Some of Kepler-90’s planets are rocky planets comparable to the Earth. There are also two large planets comparable to Jupiter and Saturn. Three of Kepler-90’s planets are the size of Uranus and Neptune. Tabloids have been calling this system our twin because of these similarities. They are even suggesting that we need to make contact with the “humanoids” living there.

The reality is that no scientist, at least in print, feels that this solar system is the same as ours. First, all of Kepler-90’s planets are closer to the sun of the system than the Earth is to our Sun. They would undoubtedly be much too hot to support any kind of life based on carbon, oxygen, and hydrogen. It is also important to note that in our solar system our large planets have a function that can only happen if they are farther from the Sun than the life-bearing planet. Jupiter, Saturn, Uranus, and Neptune all serve as shields to planet Earth. The four Jovian planets will absorb any large object from outside the solar system that is on a collision course with Earth. The famous Shoemaker-Levy 9 comet in 1992 was torn apart by Jupiter and destroyed. Had Jupiter not shielded the Earth, the collision of the Earth and Shoemaker-Levy 9 would have been devastating.

A system with a star emitting the right spectra and having rocky planets does not necessarily support the existence of life. We produced a chart titled “Evidence for Design in the Universe” that lists 47 variables necessary for a planet to harbor life. You can access the chart on our doesgodexist.org website, or request it from us and we will mail you a copy.

Astronomers haven’t yet found anything close to a twin to our planet. Even if they did, and even if there were life on it, all that would prove is that God created life elsewhere. It would indicate that the Creator carefully chose the right constants and chemical constituents to allow life to exist.

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.

Continental Drift and Recycling

Continental Drift
In 1910 an Arctic explorer by the name of Alfred Wegener coined the term continental drift. Wegener saw the same fossils in South America that he had seen in western Africa, and he proposed that the two continents had been connected at one time. Wegener’s proposal was ridiculed by the scientists of that day who saw the Earth’s crust as too solid to allow any model of that kind to work.

Over the years studies of earthquake epicenters have shown that there is movement of huge slabs of rock called tectonic plates. The rock material bends more and more steeply until the slabs eventually melt into the mantle–the molten interior of the earth. These slabs and everything on them do in fact move.

In 1952 an ocean cartographer by the name of Marie Tharp began making profiles of the Atlantic Ocean floor going from west to east. Her profiles showed a ridge down the center of the Atlantic with younger material in the center and older material on both sides. She proposed that molten material was coming up from the mantle and pushing the two slabs of ocean floor material away from each other. Where the slabs hit the edges of the continent, the material is deflected downward making trenches in the floor of the ocean.

All of these discoveries flew in the face of the accepted geological theory at the time, and Tharp was ridiculed. In time scientists came to understand that the Earth is made up of plates sliding along the surface and sliding down into the mantle when a continent is reached.

There is a message in all of this that what is considered to be scientifically impossible, sometimes turns out to be true. At the same time, a pet theory can ultimately be proven incorrect. One of the beauties of science is that eventually it cleans up its own mistakes.

Another message is that sometimes God addresses a problem long before humans know there is a problem. This whole process is one of the greatest recycling systems of all time. As nutrients and minerals get eroded off the continents, they are deposited on the ocean floor. The movement of the ocean floor ultimately returns this material to the mantle to be recycled back to the Earth’s surface.

No elements are lost from the Earth’s reservoir by this system, and it assures us that there is no waste in the resources of the planet as a whole. Jeremiah 10:12 speaks of God preserving the Earth by His wisdom, and continental drift is one of tools by which He does that.

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.”

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.
