Becoming New Creatures

Becoming New Creatures
The National Geographic Channel has been airing a very interesting new series of programs titled “One Strange Rock.” The series hosted by actor/comedian Will Smith tells about the many “strange” and “lucky” features of planet Earth that make it possible for us to live here. In the most recent episode, eight astronauts explain why they think that humans should colonize space. They and some other prominent individuals have recently suggested that colonizing other planets or living in space may be the only hope for the human race to survive. In the process we might find ourselves becoming new creatures.

This episode brings out the many ways that space life will affect our bodies. Based on present experience with the International Space Station we know that bones and muscles weaken when they do not have to overcome the effects of gravity. Body fluids shift upwards causing other physical changes. There are changes to a person’s eyesight which can be permanent. Outside of Earth’s atmospheric protection, astronauts face greater amounts of cosmic radiation that can trigger “light flashes” in their eyes. Long exposure to the higher levels of radiation may lead to cancer or brain damage. At the same time, bacteria grow faster and can become more deadly in a zero-gravity environment. The environment of space, even with the best protective gear science can devise, may at best be toxic and at worst fatal to humans.

Even with those considerations, the astronauts are saying that we must colonize space. Part of their reasoning is that humans have evolved to handle the challenges of life on this planet, and we will perhaps evolve becoming new creatures to handle the new hazards of space. They say it will just be a matter of adapting to a new environment. Will Smith said in this episode, “Even if we survive the journey and make the place feel like home, we still might not save our species. Just by being there we might turn into something else.”

I think that the real answer to human survival IS for us to turn into something else. Human survival depends on people turning away from their sinful passions and hatred. It involves becoming what God created us to be and living out the teaching and example of Jesus. Going to another planet and taking along our sinful nature with all of its baggage will not save us. The real hope for the survival of the human race does not involve leaving the planet God created for us. It does not require leaving Earth with all of its “strange” and “lucky” features that make life possible. It is not necessary for us to go to a much more hostile environment and evolve into new creatures. The answer to our survival is becoming new creatures here and now as described in 2 Corinthians 5:17.

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.”

Astronomy Picture of the Day: APOD

Astronomy Picture of the Day
One of my favorite free websites is NASA’s Astronomy Picture of the Day (APOD). Every morning I begin my day by looking at what new image is on that site. Since there is an explanation of the image, this is also an opportunity to learn about objects in space and how those objects might fit into our understanding of the universe. The picture from April 17, 2018, is called “M57: The Ring Nebula.”

M57 is known as a “planetary nebula,” but the glowing material does not come from planets. Scientists believe it is the outer layers expelled by a star very similar to our Sun. It went through a process that we see happening in space where stars explode and seed space with heavy elements produced by the explosion. What is left of the star is the tiny dot at the center of the nebula. That dot is a very dense remnant of the core of the star that is spinning very rapidly obeying the laws of physics as it does so.

This is not creation. The material this explosion produced is not coming from nothing. It is the product of previous materials that were produced at the moment of creation by a process that we cannot duplicate or even adequately describe in scientific terms. The process of fusing hydrogen to heavier elements, seeding space with all of the material produced, and reforming the material to make terrestrial life possible is outside of our capacity to observe. To some extent, it can be described with mathematical equations. The astronomy picture of the day on the NASA site continues to detail the process that produced our world and all we see around us.

God is not limited by time or space or our capacity to understand. In Job 38:4 God challenges Job to deal with “the foundations of the Earth.” In Proverbs 8:22-27 wisdom speaks about the planning and design God made before the Earth came to be (verse 23). Wisdom speaks about the preparation of the heavens (verse 27).

When we look at the astronomy picture of the day on the NASA website, we are not seeing the present. We are looking into the past. M57 went through the process of seeding its neighborhood with heavy elements 2,000 years ago, and we witness that event today. Virtually everything on the NASA website, and in astronomy, is in the past. Seeing these things allows us to wonder at the power, wisdom, and majesty of God. It reinforces David’s statement in Psalms 8:3-4: “When I consider your heavens, the work of your fingers, the moon and stars which you have ordained, what is man that you are mindful of him and the son of man that you visit him?”

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.

The Day and the Hour

The Day and the Hour-False Prophets
In 2000 Francis X. Gumerlock wrote a book titled The Day and the Hour. The subtitle was “Christianity’s Perennial Fascination with Predicting the End of the World.” The book tells about people who attempted to set a date for the coming of Christ and the end of the world (or end of the age) going all the way back to the first century. In more than 350 pages it lists numerous predictions by self-proclaimed prophets, charlatans, and even sincere people who tried to set a date. If that book had been published in 2018, it might contain perhaps twice as many pages.

The people who believed those false prophets were forgetting that Jesus said, “But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father” (Matthew 24:36). If we believe in Jesus, we should believe what He said.

Unfortunately, there is a new prediction for this month. A certain false prophet is saying that April 23 this year will be the rise of the antichrist and the beginning of seven years of tribulation. (He also predicted it would happen on September 23 and the October 1 of last year.) He bases his prophecy on politics, numerology, astrology, taking Revelation 12:1-2 out of context, and some completely bogus astronomical predictions. There is no giant rogue planet named Nibiru. The Sun, Moon, Jupiter, and stars will not align in the way the false prophet is saying. Anyone promoting this idea is either ignorant, trying to gain fame, or trying to make money.

What is the real problem here? These false claims that supposedly come from Christians make all Christians look foolish in the eyes of unbelievers. That makes it difficult to teach the truth of the Gospel to skeptics and seekers. Also, some Christians are duped by these false prophets into giving money that could better be used to share the true message of Christ.

Don’t listen to or support those who predict the time of Christ’s return. Don’t share their message with others on Facebook, Instagram, or elsewhere. Pray that all Christians may be doing the work Christ has given us to do as we remain ready for His return–whenever it will be. Remember that Jesus said nobody knows the day and the hour.

Our Unique Solar System

Our Unique Solar System
As astronomical equipment gets better, the details of stellar systems other than our own show patterns that highlight our unique solar system.

The January 3, 2018, issue of The Astronomical Journal published a report on a study of 909 planets in 355 systems discovered by the Kepler Telescope. The study shows two major patterns in neighboring exoplanets. The first is that those exoplanets tend to have similar masses. The second is that their orbits are regularly spaced from one planet to the next.

Our solar system has inner planets that have mismatched sizes, and they are widely spaced. All models of solar system formation fit what we see in exoplanets. The evidence suggests that exoplanetary systems have not been disturbed since their formation. Our system is different because it shows evidence that it has been disturbed. Jupiter and Saturn seem to be tools that modify the normal pattern of solar system formation.

In 1996 an extraterrestrial rock fragment was discovered in Egypt called the Hypatia stone. The mineral composition of that stone is unlike any other known object in our solar system. Scientists think that it originated outside of our system. Our solar system seems to be unique in both structure and chemical makeup. Astronomers are discovering indicators of how God created the Earth and all of the things that allow life to exist on it.

The design of our unique solar system compared to other systems helps us to understand that we are not a product of chance collisions or explosions in space. The simple statement of the Psalmist in Psalms 19:1 has a different frame of reference now than when it was written. It is truer today than when the ancient shepherd looked at his sky and wrote, “The heavens declare the glory of God and the Earth shows the work of His hands.”

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.

Expanding Universe and What It Means

Expanding Universe
We live in an expanding universe. For thousands of years, from Aristotle to Einstein, scientists thought that the universe was eternal. Einstein’s equations proposed in his general theory of relativity in 1915 seemed to indicate that the universe was not stable. Einstein thought it was a mistake and tried to correct for the “error” by creating a variable called the “cosmological constant.” The only error was the cosmological constant, and Einstein later called it “the biggest blunder of my life.”

Later in the 1920s, Edwin Hubble found strong evidence that the universe was expanding. That evidence was further confirmed in 1964 when radio astronomers accidentally discovered the cosmic microwave background. It was finally confirmed by space-based experiments in the twenty-first century.

The rate of expansion of the universe based on experiments was established and is known as the Hubble constant. On February 22, 2018, a new survey of the expansion rate was released. This scientific paper was based on the most precise measurements of the universe’s expansion rate using the Hubble Space Telescope. Scientists are surprised to discover that the expansion rate is faster than they thought. This new information may require some re-evaluation of the scientific understanding of the universe.

This is not the first time a re-evaluation was needed. Evidence of an expanding universe indicates that it had a beginning. If you trace the expansion backward through time, you can see that at one point the entire universe would have been compacted into a single point. The evidence of the expansion shows that the universe had a beginning when that expansion began. Since the expansion is accelerating, that means that the universe will never contract back and start over. Therefore, the universe is not eternal. It had a beginning, and it will have an end.

The bottom line is this: What did Moses know that Einstein and scientists before him did not know? That the universe had a beginning. “In the beginning, God created the heavens and the earth” (Genesis 1:1).

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.
