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.”

Lyrid Meteor Shower Peaks

Lyrid Meteor Shower
For viewers in the Northern Hemisphere, the early morning hours of Sunday, April 22, will be the best viewing time for the 2017 presentation of the Lyrid meteor shower. From mid-April this year to about April 25 the “shooting stars” are visible with as many as a dozen or so per hour. However, on Sunday morning there will probably be up to 20 per hour.

The Lyrid meteor shower comes around every year in April. There are ten significant meteor showers each year, but the last one was the Quadrantid meteors in early January. Now, at last, with the weather a little warmer we have another chance to watch the sky.

The Lyrid meteor shower gets its name from the fact that it seems to radiate from the constellation Lyra, the harp. No, they are not “shooting stars.” The Lyrid meteors are actually fragments broken off from Comet Thatcher which passed by in 1861. That comet makes a pass through our solar system every 415 years or so.

The Comet Thatcher has been passing through and leaving bits behind for a long time because Chinese sky watchers saw the Lyrid meteor shower in 687 B.C. Apparently they were impressed because they recorded that “stars fell like rain.”

Of course, the ancient Chinese didn’t know what caused the event. We know that it’s the result of those comet pieces falling into our atmosphere, being heated by the friction of the air, and burning up. Our atmosphere does more than just give us oxygen to breathe. It also protects us in many ways. One of those protections is that it causes most objects falling from space to burn up before they reach Earth’s surface. That friction requires heat-shield protection for returning Astronauts, but those of us living on the Earth’s surface can be glad to have an atmosphere to protect us. Recently a Chinese space station the size of a bus fell into our atmosphere and disintegrated before reaching the ground. You don’t need a telescope to see the pockmarks on the Moon’s surface from asteroid impacts because the Moon has no atmosphere.

Speaking of the Moon, it will be in its first-quarter phase and will not set until about 2 A.M Sunday morning. For that reason, viewing the Lyrid meteor shower will probably be best between 2 A.M. and the first light of dawn. However, if you miss it then, you still have a few more days, but the meteors will be fewer and farther between. If you see the Lyrid meteor shower, let it be a reminder of the fact that God has designed a planet that provides for our needs and protects us while we enjoy its beauty.

Earth’s Magnetic Field

Earth's Magnetic Field
You might say that planet Earth is a very large magnet. We have mentioned before Earth’s magnetic field that is generated by the iron core. The movement of that molten iron generates a magnetic field surrounding our planet. We can see the effect of that field every time we use a compass to find directions.

What you may not realize is that there is also a magnetic field generated by the ocean. Salt water is a good conductor of electricity. Moving electric currents generate magnetic fields. Hans Christian Ørsted discovered that by accident in 1820 when he noticed that placing a compass near a wire carrying an electric current caused deflection of the compass needle.

Salt dissolved in the oceans’ water creates ions, which are electrically charged particles. The movement of ocean tides causes those charged particles to move. Electric current is electrically charged particles in motion. Since electric current generates a magnetic field, the ocean tides generate magnetic fields. Because the movement of ocean currents and tides is complex, the magnetic fields generated by the oceans are more complex than the big magnetic field of the Earth. They are also 20,000 times weaker than Earth’s main magnetic field making them harder to measure.

Today’s satellite technology allows us to map the oceans’ magnetic field. The European Space Agency used three satellites to create a network called “Swarm.” They used the data from those satellites to create a 3-D digital map of this little-known magnetic field. The research shows how the field changes over time. Although the oceans create a relatively small part of Earth’s magnetic field, they play an important role. Mapping this field also give scientists a better picture of how the oceans flow all the way down to the seabeds. That information gives us a better understanding of Earth’s climate.

Combined with the magnetic field produced by the molten core and rocks in Earth’s crust, we are protected by a “cocoon” surrounding our planet. You might say, “Protected from what?” Our Sun frequently erupts in solar storms releasing charged particles that escape into space. Many of those particles travel to the Earth. We call it “solar wind.” Without a protective magnetic shield, those particles would reach Earth’s surface disrupting power grids and aircraft navigation. More basic than that, they would damage human cells causing cancers and other health problems.

We don’t think it’s by chance that we have the protection of Earth’s magnetic field. We see this as one more evidence of the provision of God to make possible life on this planet.

Life Needs Phosphorus

Life Needs Phosphorus
The element phosphorus is used to make matches. Molecular phosphorus has two common forms. There is white phosphorus which is dangerously combustible and is used to make fireworks and weapons. The more stable red phosphorus is used on the side of any box of safety matches. When you strike the match against the red phosphorus, a small amount of it is changed to white phosphorus to ignite the match. But phosphorus has more important uses than starting fires. Life needs phosphorus. The average human body contains about 26.5 ounces (750 grams) of phosphorus. Most of it is in our bones.

Phosphate is a compound of phosphorus and oxygen. It combines with sugars in living tissue to form the backbone of DNA, which is the blueprint for life found in every living cell. Phosphate is also part of a complex organic chemical called adenosine triphosphate (ATP) found in every living organism. ATP releases energy so that cells can function. Life needs phosphorus and could not exist without it in an abundant supply.

Recent research presented at the European Week of Astronomy and Space Science on April 5, 2018, indicates that phosphorus may not be widely available in the Milky Way. The research indicates that it is more random than scientists had previously thought. That means even if one of the recently discovered exoplanets had all of the conditions required to support life, it still might be lifeless without phosphorus.

We have often referred to the many conditions required to make a habitable planet. Here is one more to add to the list. Life needs phosphorus, and apparently phosphorus is less widely distributed than we thought. Phil Cigan, one of the astronomers involved in the study, said, “It’s not a guaranteed thing to have phosphorus abundant everywhere, ripe for the picking. It seems to look like luck plays a bigger role in this.”

Is it just one more chance coincidence that planet Earth has the phosphorus needed for life? We don’t think it is a matter of luck. We think this is another evidence of God’s design for life.

Tectonic Plates, Earthquakes, and Volcanos

Tectonic Plates Map
Tectonic Plates Map

Yesterday (April 5, 2018) there was a magnitude 5.3 earthquake off the coast of California near Los Angeles. No serious damage resulted, but scientists say there is a one-in-twenty chance that quake could be the foreshock of a larger quake. This brings up the question of why we have earthquakes. Did God do a poor job of designing the Earth?

The answer to that question is, “No.” Earthquakes result from factors that are essential for life on Earth. Earth’s crust consists of tectonic plates floating on the mantle, which is a region of molten rock. Under the continents, the Earth’s crust averages 18 miles (30 km) thick. Under the oceans, the crust is only about 3 miles (5 km) thick. The mass of the crust puts great pressure on the molten rock in the mantle causing it to be very viscous. If a crack opens in the crust, the molten rock will move upward, become more liquid as it is under less pressure. Then it may burst from the surface creating a volcano.

Volcanoes create mountains, and so does the movement of the tectonic plates. The tectonic plates moving against each other also produce earthquakes. Sometimes the plates will move against each other horizontally. We call that a slip-strike earthquake and that is what happens in the San Andreas fault in California. The quake that just occurred was a thrust quake where one side of a fault thrusts over the top of the one next to it. The Rocky Mountains and the Himalayas were pushed up by movement of the tectonic plates.

By the creation of mountains, the Earth has been continuously renewed. On the surface of the continents, erosion, and weathering break up solid rock to produce sand, clay, and ultimately topsoil. Erosion cuts down the mountains and deposits sediment in the lower elevations. Further erosion carries the sediment out into the oceans. In the deepest parts of the ocean, there are trenches. Huge amounts of sediment settle into those trenches, but they never get full. That’s because the sediment sliding into the trenches is finding its way down into the mantle.

The movement of sediment replenishes the mantle with new material which then resupplies the continents with new rock. Volcanoes erupt bringing recycled minerals and nutrients to the surface. Volcanic soils are the richest soils on Earth. This system has also brought the iron and other essential minerals into the Earth’s crust.

This is a greatly oversimplified explanation of the comprehensive recycling system that God designed into the planet on which we live. Earthquakes and volcanoes are destructive when humans build homes and cities close to the fault lines and active volcano sites. But if the Earth’s recycling system didn’t exist, erosion would eventually reduce the land masses to sea level, and Earth would be a water world.

One Strange Rock

One Strange Rock
The March 2018 issue of National Geographic features an article with the title One Strange Rock. A NatGeo TV presentation by the same name premiers today. The subtitle of the magazine article says: “13 things that make life on Earth possible.”

For many years we have presented these variables in our videos and audios, books and articles. While new data has expanded these concepts, the fundamental design features of the cosmos remain an excellent argument for the existence of God and His role in the creation. Here are the 13 variables that National Geographic presented to support the idea that Earth is one strange rock:

“#1. OUR PLANET RECYCLES LIFE-FRIENDLY CARBON OVER TIME.
#2. WE HAVE AN OZONE LAYER TO BLOCK HARMFUL RAYS.
#3. WE HAVE A BIG MOON TO STABILIZE OUR AXIAL WOBBLE.
#4. EARTH’S VARIED SURFACES SUPPORT MANY LIFE FORMS.
#5. OUR MAGNETIC FIELD DEFLECTS SOLAR TEMPESTS.
#6 WE’RE AT JUST THE RIGHT DISTANCE FROM THE SUN.
#7. WE’RE SITUATED SAFELY AWAY FROM GAS GIANTS.
#8 THE SUN IS A STABLE, LONG-LASTING STAR.
#9. WE HAVE THE RIGHT STUFF TO HOST A DYNAMIC CORE.
#10. WE HAVE GIANT PLANETS THAT PROTECT US FROM AFAR.
#11. OUR SUN OFFERS PROTECTION FROM GALACTIC DEBRIS.
#12. OUR GALACTIC PATH STEERS US CLEAR OF HAZARDS.
#13. OUR LOCATION IS FAR FROM STELLAR CROWDS.”

We encourage you to view our video series which begins by looking at these variables and showing the probability factors for these and other variables. The point of our discussion is that when you calculate the odds of these things happening by chance, you end up with a probability that is statistically unacceptable.

The conclusion of National Geographic in the article is:

“Earth is well equipped as a planet and ideally placed in our solar system and galaxy to support life as we know it. The product of some 4.6 billion years of cosmic construction, our planet is flush with life thanks to a fortuitous set of conditions, from the optimal chemical makeup of our planetary core to our safe distance from the hidden black hole at the heart of our galaxy.”

Construction suggests an intelligence doing things in a logical order. Blind chance is not a method, and chance produces as much chaos as order. These 13 variables are just astronomical parameters. There are also design features seen in the creation of physical laws and the laws of quantum mechanics that allow stable atoms to exist. Planet Earth is far more than one strange rock.

The more we know of the creation, the more we know of the Creator. Our knowledge is increasing daily which means the evidence for God’s existence also grows daily.

Searching for Other Worlds

Searching for Other Worlds
In 1999 astronomers detected the first exoplanet–a planet in another solar system. The number of planets detected orbiting around stars other than our Sun has grown to more than 3,500 today. There are billions of stars in our Milky Way Galaxy so searching for other worlds is just getting started.

NASA’s main tool for finding exoplanets has been the Kepler space telescope. The method of detecting those planets is watching for occlusions. If there is a planet orbiting a star, it will sometimes pass in front of that star from our viewpoint causing an occlusion or mini-eclipse. The planets are too small for us to see, but we can see a small dip in the light coming from the star. If the dip comes on a regular interval that means it might be an orbiting planet. The amount of the dip in light level indicates the size of the planet in relation to its star. Using this method of detection, astronomers have compiled a catalog of detected planets.

As I said, until now the Kepler telescope has been the method for finding most of these planets, but it will soon end its life. However, 2018 will be the beginning of new opportunities to look for exoplanets because of two new satellite-based observatories. Very soon NASA will launch TESS. That stands for Transiting Exoplanet Survey Satellite. By the end of the year, the European Space Agency (ESA) will launch CHEOPS or Characterising Exoplanet Satellite. (Aren’t you glad we have acronyms.)

The Kepler telescope was very good at searching for other worlds, but only in a small area of the sky. TESS will take a much wider view with the hope of finding many more. For obvious reasons, so far most of the planets detected are giant planets. TESS will be targeting bright stars in the hope of finding smaller planets that more closely resemble Earth. Astronomers will be able to target TESS more precisely toward selected stars.

It will be interesting to see what new discoveries will come from the investment of time and more than a quarter of a billion dollars. So far there have been no more than a dozen planets that even come close to being possible outposts for life. As we have said before there are many parameters required to sustain any kind of life and even more to support advanced life. We have also said many times before that whether there is life anywhere else in the cosmos has nothing to say about whether God exists. A God who is great enough to create the cosmos can create life anywhere He chooses. We are just glad He chose planet Earth so scientists can continue searching for other worlds.

Tree Rights: Do Trees Have Feelings?

Tree Rights
A German forester and author named Peter Wohileben has written a book titled The Hidden Life of Trees: What They Feel, How They Communicate. The book has sold more than 800,000 copies in Germany and has hit the best-seller list in 11 other countries including the U.S. and Canada. He was quoted in the March issue of Smithsonian magazine as saying, “We must at least talk about the rights of trees.” Since we are concerned about human rights should we also be thinking of tree rights?

According to the article in Smithsonian, scientific evidence indicates “that trees of the same species are communal, and will often form alliances with trees of other species.” Wohileben says that trees in every forest “are connected to each other through underground fungal networks. Trees share water and nutrients through the networks, and also use them to communicate.” What Wohileben is talking about is a symbiotic relationship between trees and fungi underground. The hair-like root tips of trees join together through fungal filaments to form a mycorrhizal network. The fungi consume sugar from the tree roots as they pull nitrogen, phosphorus, and other minerals from the soil which are absorbed by the roots for use by the trees.

The trees communicate through their “wood-wide-web” by “sending chemical, hormonal and slow-pulsing electrical signals.” The large trees with deep roots draw up water which benefits the shallow-rooted trees. The article says that trees also share nutrients with each other, even between species. In addition to the underground network trees also communicate with each other through the release of chemicals into the air, and they release large amounts of moisture into the air feeding rain systems.

Wohileben presents his story of the trees as if they have intelligence. He says that we must “allow some trees to grow old with dignity, and die a natural death.” Multiple scientists refute Wohileben saying that trees are not “sentient beings” and call Wohileben’s ideas anthropomorphism.

We believe that God has given us the duty to protect the environment. That includes trees. (Genesis 2:9, 15) However, we see great danger in talking about tree rights. Plants and animals are here to serve humans, and we are here to serve God.

OSIRIS-REx Photograph

OSIRIS-REx
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 an asteroid named 101955 Bennu, to take a sample from it, and return that sample to Earth. Scientists hope that studying that asteroid sample will help us learn more about the formation of our solar system. The project will cost about one billion dollars.

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 upper 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.

The spacecraft is expected to reach Bennu this summer and will orbit the asteroid until July of 2020 when it will land and gather a sample. In September of 2023 is it scheduled to deliver that sample to the scientists on Earth. The purpose is to learn more about this near-Earth asteroid. The hope is that will help us 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.

Driving to Mars in a Red Convertible

Driving to Mars
On February 6 SpaceX launched a red Tesla roadster convertible owned by billionaire CEO Elon Musk in a trajectory toward Mars. The photo from an onboard camera shows the dummy driver leaving Earth and driving to Mars.

Will the car ever get there? Astronomers say that it will go into orbit around the Sun and eventually come to the vicinity of Mars. However, it will probably not come very close to the planet depending on the timing of orbits. It has no onboard thrusters to adjust its direction for driving to Mars. At any rate, it will take several months to arrive anywhere near Mars. The closest Mars ever comes to Earth is 33 million miles (54.6 million kilometers). It takes a long time to “drive” that far.

Musk has been promoting the idea of colonizing Mars. His company has developed the world’s most powerful space rocket, the Falcon Heavy Rocket, which they used to launch Musk’s car. However, Mr. Musk doesn’t seem to be doing much to solve the problems of interplanetary space travel. For humans to survive on long space flights away from the protection of Earth’s atmosphere and magnetic field, will require much more effort than launching them into space.

Earth has been designed to shield us from the deadly effects of space. Of course, the vacuum of space would be deadly to anyone not in a pressurized suit or cabin. That problem has been solved to allow astronauts to live in the International Space Station and make spacewalks. If the tires on the car were pressurized, I suspect they would have blown out by now. Another problem is food, medicine, and other supplies. Resupply launches provide for the needs of people on the ISS, but that would not be practical for people traveling to or colonizing Mars.

Perhaps the biggest challenge is cosmic radiation and debris coming from outer space. Earth’s atmosphere is designed to protect us from those things. The space station in low Earth orbit is still somewhat within the magnetic field of Earth. In outer space, the only protection is what you can take with you. Apparently, from what Elon Musk posted on Twitter, his car was headed on a dangerous trip into the asteroid belt beyond Mars.

Musk said in a news conference that the car was “just going to be out there in space for maybe millions or billions of years.” That may be doubtful. Musk admitted that SpaceX had not tested the materials of the red convertible for space endurance. The mannequin space traveler is wearing an authentic space suit, but the car is made of the usual materials. Even if the car avoids major collisions with asteroids, it will become riddled with pockmarks from micrometeorites. Leather, fabrics, plastics, and even the carbon-fiber frame will break down from exposure to unfiltered sunlight and cosmic radiation. The carbon-carbon and carbon-hydrogen bonds in those materials will break down, and the car will fall apart. At least one scientist, William Carroll, a chemist at Indiana University and an expert on plastics and organic molecules, said, it won’t last a year in space.

One more thing to note is that the radio in the car was playing David Bowie’s song “Space Oddity.” However, sound can’t travel through a vacuum, and since there is no atmosphere in space, the radio is playing the sound of silence. The battery will run down in a short time anyway. Driving to Mars is going to be a challenge, even in a well-designed spaceship. The need for power, food, protection from the elements and many other things, make us very happy to live on planet Earth. It almost seems as if Someone designed this place for us to call “home.”
