God Positioning System and What it Means

Homing Pigeon - God Positioning System and What it Means
Homing Pigeon

The Spring 2021 issue of God and Nature published an article by Angie Cornwell about the “God Positioning System.” During World War I, a homing pigeon saved the lives of almost 200 American men by carrying a message 25 miles despite being bombarded with gunfire. People have used homing pigeons for thousands of years to carry messages in all kinds of terrain, all kinds of weather, and in unfamiliar territory. Studies of how homing pigeons do this have concluded that they use at least five different systems. If one method doesn’t work, they use a different one. One technique is visual, using familiar landmarks. A second involves the use of environmental odors. A third system consists of using Earth’s magnetic field. A fourth system uses infrasonic (low frequency) signals, and a fifth system uses information stored in the pigeon’s brain.

Humans have a difficult time learning how to navigate in unfamiliar environments. For most of my life, I have relied on maps, but they are hard to use. You have to know where you are on the map, and folds in the map can cause misinformation. The invention of the global positioning system (GPS) has eliminated the weaknesses of maps. When in our human arrogance, we think we have a better way than the GPS has advised, causing us to get lost, the GPS will jump back in and guide us back to where we wanted to go.

Christians have a special GPS which Angie Cornwell has called the God positioning system. There are many similarities to the global position system. The God positioning system finds us wherever we are in life and directs us to where we need to go. When our arrogance causes us to choose a destructive path, we can turn back to the God positioning system to find our way.

God, in His mercy, has given us the ultimate navigational system to find our way back to Him. He has given us His Word to follow and His Holy Spirit to guide us. The global positioning system uses three satellites to triangulate our position. God the Father, Jesus Christ, His Son, and the Holy Spirit can pinpoint our spiritual condition and navigate us toward our eternal home. We never have to be desperately lost or alone. We don’t have to struggle to figure out where we are and how to get where we need to be.

Science hasn’t completely figured out all of the things that allow homing pigeons to navigate, and our human wisdom does not allow us to comprehend how the God positioning system works. The good news is that we don’t have to understand either one to take advantage of all they do for us.

Does Your GPS Work?

Does Your GPS Work?
Does Your GPS work? If so, you can give credit to Albert Einstein. In 1905 Einstein published the Theory of Special Relativity which said that nothing can travel faster than the speed of light. This presented a problem because gravity acts between objects instantly and thus it seems to be faster than the speed of light. It was a problem that needed a solution.

Ten years later, in 1915 Einstein revealed his Theory of General Relativity which resolved the problem. The explanation was that the Sun and planets cause space to curve around them and this warped shape of space influences the motion of other objects passing by them. That’s why the Moon orbits the Earth, and it’s why Earth and the other planets orbit the Sun.

This warping of space also bends light beams that pass through space. In 1919 British astrophysicist Arthur Eddington confirmed that Einstein was correct. Eddington observed the bending of light from distant stars as the light passed by the Sun during a total solar eclipse.

The understanding of how gravity bends space and light beams has given us methods of making measurements in space and detecting planets orbiting other stars. Einstein also said that time is warped by gravity causing time to move more slowly near massive bodies like the Earth. The effect of gravity on time allows Global Positioning Satellites to determine the exact position of the GPS receiver you use in your car.

Does your GPS work? If it does, it works because brilliant minds have discovered many of the amazing details of God’s creation. We have been able to apply the things we have learned, but science has only scratched the surface of understanding the work of the Creator.

Advanced Civilization Support

Advanced Civilization Support
We have often mentioned before the evidence that our planet was designed to support life. More than that, it was designed to support advanced life. It was even designed for advanced civilization support.

You can see evidence for advanced civilization support in the minerals of Earth’s crust—minerals that are essential for machinery and electronics that enable technology. One thing which perhaps you have not considered is how the size of our planet also supports advanced civilization. Among the achievements of science is space flight. The ability to use rockets to leave Earth’s surface makes it possible for us to place satellites in orbit. Those satellites include:

*Communication satellites which make possible nationwide and international television, news, sports, telephone, and video conversations.
*Global positioning satellites giving us GPS which we use for many purposes including airplane, ship, and personal navigation plus farming and safety uses.
*Weather satellites giving us advance warning of storms and helping to keep us safe.
*Observational satellites that allow us to study and learn more about our planet.
*Telescopic satellites which enable us to study our solar system and the universe.

We often fail to realize how important those satellites are for our advanced civilization. Also, the ability to use rockets to leave Earth’s surface allows us to send out space probes to explore our solar system and universe.

What does the design of our planet have to do with our ability to leave the surface? The answer relates to gravity. Astronomers have been looking for habitable planets orbiting other stars. They believe that they have found many of those exoplanets. However, the planets that are more likely to be located in habitable zones (where liquid water can exist) are much larger than Earth. A much-larger rocky planet would have much more mass and therefore much more gravity. Launching a rocket into space from such a planet would be much more difficult, if not impossible. Even airplane flight and the flight of birds could be affected by increased gravity.

A planet with a diameter 70 percent greater than Earth’s diameter would have ten times the mass. The advantage of having much more gravity would be that a planet like that could hold a thicker atmosphere which could give more protection from harmful cosmic rays and incoming asteroids. The disadvantage of a thicker atmosphere would be that it might also block useful solar rays. However, getting a rocket off the ground and into space could be prohibitive. It would require a much larger rocket which would require more fuel. That would require an even larger rocket to carry the extra fuel. The weight of the larger rocket and fuel would require an even larger rocket requiring even more fuel. This quickly spirals out of control.

So what is the conclusion? We live on a planet that is large enough to hold an atmosphere that protects us but small enough that we can to break the bond of gravity to go into space. A smaller planet would not have the atmosphere we need. A larger planet would not allow us to explore beyond our planet or even to send up satellites that help to make advanced civilization possible. As Goldilocks might say, “God made it just right.”

The Value of a Total Solar Eclipse

Albert Einstein and the value of a total solar eclipse
Here is an interesting story of how a solar eclipse helped to confirm a scientific theory and demonstrated the value of a total solar eclipse.

Yesterday, we pointed out that it’s more than a “marvelous coincidence” that the Moon can exactly block our view of the much larger Sun. It’s an evidence of design. When the Moon hides the Sun’s photosphere, scientists can study the chromosphere and the corona to learn more about the Sun and how it affects life on Earth.

In 1687 Isaac Newton presented his universal law of gravitation answering many questions about gravity. One question that remained unanswered was how gravity can act through empty space.

In 1916 Albert Einstein presented his theory of general relativity in which he proposed that mass produces gravity by warping space. Planets orbit the Sun because the mass of the Sun and the planets causes space to be curved. The theory suggested that light would also follow a curved path because of this warping. Einstein calculated how much light would bend near a massive object and proposed that light from distant stars would be bent when it passes by the Sun.

Einstein’s idea seemed hard to believe, but there was no way to disprove it since the bright Sun hides any starlight passing near it. You can’t see the stars during the day.

Then in 1919, British astrophysicist Arthur Eddington made some measurements during a total solar eclipse. While the Moon blocked the Sun’s photosphere, Eddington made precise measurements of the apparent position of stars that were visible near the Sun. Comparing those measurements with the positions of the same stars at night, he confirmed that Einstein was correct. The light was bent as it passed by the Sun.

The eclipse of 1919 demonstrated the value of a total solar eclipse. Many eclipses since then have added to our scientific knowledge. Understanding how gravity warps space has allowed us to make accurate Global Positioning Satellites. We use GPS in our cars for driving, in our tractors for farming, and in our smartphones for hiking, and for many other things. God designed and engineered an amazing world and gave us the ability to understand it through scientific study. Science and faith are friends–not enemies.
