International Dateline Where Days Divide

International Dateline Where Days Divide
Because the Earth is always turning on its axis, we have periods of day and night. To establish consistent times for daylight and darkness, humans have divided the Earth into 24 time zones. At one point we call the International Dateline, the days divide.

As you travel around the world east to west, the time becomes earlier. As you go west to east, it becomes later. In the United States, the time on the west coast is three hours earlier than the time on the east coast. At some point on the Earth, the time has to change by 24 hours. We call that the International Dateline (IDL) and it runs from pole to pole through the middle of the Pacific Ocean. A new day, or a new year, always arrives first on the west side of that line. Then it progresses around the Earth, hour by hour until it returns to the east side of the IDL.

The Earth always has day and night at the same time because it’s a rotating sphere. People in antiquity didn’t understand that. Also in ancient times when people did not have electric lights, they worked only during the day and slept at night. However, 2000 years ago Jesus talked about an event that will take place in an instant, but he said that it will be daytime and it will be nighttime. He also said that some people will be working (daytime activity) and others will be sleeping (nighttime activity) when the event takes place.

You can read the words of Jesus in Luke 17:30-35. How did He know that day and night take place at the same time? I think it was because he was more than a man. In fact, I believe He created day and night. (See John 1:1, 2, 14.)

Evidence from Cosmology

Evidence from Cosmology
One of the most compelling arguments for the existence of God is the basic question of creation itself. In our materials, we make an elementary and easy to understand presentation that there was a beginning, that the beginning was caused, and that the cause was a personal intelligence. We show that the cosmos was created with purpose and intelligence that can be seen by a careful study of the evidence of design that is all around us. This is evidence from cosmology.

Since our presentation is at an elementary level, many times we receive questions which express a desire for more in-depth explanations. One of the best articles that we have seen on the evidence from cosmology was published in the September 2018 issue of Perspectives on Science and Christian Faith which is the Journal of the American Scientific Affiliation (Volume 70 #3 pages 147-160). The title of the article is “The Fine-Tuning of the Universe: Evidence for the Existence of God?” It was written by Walter L. Bradley Ph.D. from Texas A & M and Baylor Universities.

The article is a technical analysis of the evidence from cosmology and concludes with: “The nature of nature, especially fine-tuning, provides clear and compelling evidence for our all-powerful, loving Creator God, who can be seen through ‘the things that have been made, so those who do not believe are without excuse’” (Romans 1:20).

Fragile Lunar Temperature

Fragile Lunar Temperature
When astronauts landed on the Moon in the 1970s, they left several instruments behind that continued to send data to the Earth. Among those instruments was a set of temperature probes bored into the surface that measured how heat travels through the lunar soil. The data from those instruments indicate a fragile lunar temperature.

Scientists had assumed that heat flows out from the Moon’s core, just as it does on Earth. The question was how fast it was flowing and was this due to residual heat in the core of the Moon or due to radioactive decay inside the Moon. They were amazed to discover that heat was flowing into the Moon instead of out of it.

Later measurements showed that the heat flow into the Moon only happened where the astronauts had been walking and where the rover drove. Scientists now agree that the footprints of the astronauts and the tracks of the rover compressed the lunar sediment which darkened the print. Sunlight was absorbed more efficiently in the darkened areas. Thus it was the absorption of sunlight which caused the elevated temperatures in the borehole and made it appear that it was a lunar feature. A detailed treatment of this research appeared in the Journal of Geophysical Research: Planets in May of 2018.

We are only beginning to understand how delicate the creation process is. The fragile lunar temperature indicates that a small variation can alter the end product of the process. God’s creation of the cosmos demanded incredible knowledge of all this and continues to sustain it today.

Our increase in knowledge further emphasizes the wonder expressed by David in Psalms 8:3-6: “When I consider your heavens, the work of your fingers, the moon and the stars, which you have ordained, what is man, that thou art mindful of him, and the son of man, that you visit him. For you have made him a little lower than the angels, and have crowned him with glory and honor. You made him to have dominion over the works of thy hands; you have put all things under his feet.”

Evolution Does Not Explain Creation

Evidence from Cosmology
The notion of God as the creator has escaped our world today. We have not understood that there was a beginning, that God caused the beginning, and that His imprint is on all we see around us. We have been told that evolution explains all these things, but in reality, evolution doesn’t address the question. Evolution does not explain creation.

Evolution assumes that time has been created. Evolution assumes that space has been created and that matter/energy has been created within space/time. Evolution assumes that forces we are just beginning to understand shaped the matter/energy in space/ time so that stable physical matter came into existence. It assumes that the properties of matter/energy caused it to become organized into galaxies, and stars, and solar systems.

Evolution further assumes that within one of those solar systems a planet was created within the Goldilocks zone where water could exist as a liquid. On that planet, carbon and oxygen and heavy metals were produced to allow tangible matter to exist for long periods of time. Then evolution assumes that within a limited time these materials came into existence in an environment and with a catalyst that could produce life.

Once all those assumptions have been made, evolution attempts to explain how that first life changed to eventually become us. In other words, evolution tries to explain how once the creation happened, things got to be as they are today. Evolution does not explain creation.

Why So Much Stuff in Space?

Why So Much Stuff in Space?
One of the questions people ask about God’s creation is why so much stuff in space? If humans are the focus of God’s creation, why did He create so many planets, galaxies, and stars? If God’s purpose was to have the human race as the battlefield for the struggle between good and evil, surely He didn’t need to create 100 billion other stars in our galaxy and billions of other galaxies.

There are so many assumptions involved in this question that it would take many more pages to explore them all. First, this question assumes that God’s creation of life only happened here. It assumes that there are no other planets anywhere in the creation that have sentient beings living on them. You can argue that forever, but the Bible doesn’t give an answer. The Bible only describes Earth because it presents a message for our planet and its people.

The question also assumes that God only intended for us to live on the surface of this planet. I get letters regularly from people who suggest that we have no business going into outer space because God intends for us to live here and nowhere else. That is a massive assumption, and one that I suggest is misguided. One recent discovery has given another possible answer to why so much stuff in space. Humans are rapidly exploiting the mineral wealth of planet Earth. We know that the Earth contains a finite amount of iron, nickel, cobalt. If we should survive on Earth for much longer than the 21st century, we are going to run out of resources.

Japan’s robotic spacecraft Hayabusa 2 visited asteroid 162173 Ryugu (pictured) in June of 2018. Data from the spacecraft indicates that this asteroid is composed almost entirely of nickel and iron. The spacecraft was returning a sample to Earth for analysis. This asteroid is one kilometer wide, and at the current market value, the iron and nickel in the asteroid are worth over 80 billion dollars. God’s plan for us may be far greater and longer than we realize. Space contains a wealth of mineral resources. God has provided for us in many ways, and we always seem to have just enough of a resource to get us to the next source. We had just enough wood to get us to hydrocarbons, and just enough hydrocarbons to bring us to nuclear and solar power.

Our problem is not resources. Our problem is being able to get along with each other well enough to avoid destroying ourselves. Jesus Christ has the answer to that major issue, but the size of the cosmos merely reflects God’s power and wisdom. As we wonder why so much stuff in space, we have to think of the words of the psalmist, “What is man, that you are mindful of him? And the son of man, that you visit him? For you have made him a little lower than the angels, and have crowned him with glory and honor. You made him to have dominion over the works of your hands; you put all things under his feet” (Psalms 8:4-6).

Growing Interest in Astrology

Growing Interest in Astrology
While more and more Americans are denying faith in God, belief in astrology, witchcraft, and sorcery is growing. Astrology academies and internet users of natal charts have produced thousands of podcasts, Facebook pages, YouTube channels, mobile apps, newsletters, and streaming videos. Data crunchers tell us that there are more than two million websites on astrology, and entrepreneurs are using astrological signs as a means of attracting business. There are sun-sign PJs, hotels with a zodiac theme, and offers for foods like a “cuppa zodiac coffee.” There is indeed a growing interest in astrology.

Richard Smoot speaking for the International Society for Astrological Research said, “So much is going on in people’s lives these days, so much pressure to act or react, and they simply want to sort things out.” Astrologers claim that people in crisis are drawn to astrology because they want guidance in matters of love, finance, and career. The astrology site Co-Star says “This generation is wrapping itself in the blanket of the zodiac to try and make sense of a world that seems to be coming apart at the seams.” The most highly rated astrological site in recent months has been “How to find the perfect dog based on your zodiac sign.” There is a growing interest in astrology among millennials who make up seventy-three percent of those visiting that site.

In the ancient world, astrologers and magicians were a major factor in helping people make decisions. In Exodus 7:11 Pharaoh used secret arts to duplicate what Moses did. God condemned the use of astrology, magic, and sorcery from the beginning. In Leviticus 20:6 we read, “If a person turns to mediums and necromancers, whoring after them, I will set my face against that person and will cut him off from among his people.” Fortune telling was condemned in Micah 5:12 and in the New Testament every confrontation between the apostles and a sorcerer or magician reveals a rejection of those practices. (See Acts 8 and Acts 13:6.)

Is astrology a harmless game or joke, or is there a reason to reject the mystic arts? The first point we need to make is that there is no scientific support for any of these mystic arts. Studies of astrological claims indicate no support for any connection between the stars and what happens in people’s lives on Earth.

Magic is entertaining, but honest magicians will tell you that even their most amazing acts are sleight of hand and visual tricks. It is enjoyable to watch these talented performers, but we need to realize that they are not using supernatural abilities. Sorcery and witchcraft are dangerous and destructive activities and have a long history of tragedy. The bottom line is that all mystic arts draw people away from the real solutions to their problems.

In today’s world, when people reject the Bible and its teachings they are left with no help in making critical decisions. In that void, they seek out unhealthy and destructive substitutes. There may be a growing interest in astrology as a place for people to find answers in life, but it is as harmful and misleading as ever.

‘Oumuamua: Mysterious Space Visitor

'Oumuamua: Mysterious Space Visitor
In October of 2017, astronomer Robert Weryk using a telescope in Hawaii discovered an object careening through our solar system from somewhere in interstellar space. Astronomers assumed it was an asteroid from some other stellar system in our galaxy. UFO promoters saw it as a spaceship from some other star system that was spying on our planet. The name given to it is ‘Oumuamua which is Hawaiian for “scout.”

The object was quite narrow and seem to be less irregular than most asteroids. Closer examination has shown that the surface of the object is a reddish color which is typical of some comets which have a crust covering an icy interior. Its size is approximately 800 by 100 feet (230 by 35 meters).

Studies of the trajectory of ‘Oumuamua show it is tumbling and changing directions in a way that indicates a force other than the Sun’s gravity working on it. Naturally, the UFO promoters were overjoyed saying that this proves that alien spacecraft are all around us, and we just happened to catch this one. The SETI Institute used its powerful Allen Telescope Array to examine the object but detected no radio signals indicating intelligence. The problem with the UFO idea is that the change of direction is much smaller than what rockets on a spacecraft would cause. The overall trajectory of ‘Oumuamua has not changed significantly as it heads out of the solar system. It is traveling to fast for any of our existing spacecraft to reach it, but it will still take 20,000 years to be completely clear of our solar system.

After much study, astronomers concluded that ‘Oumuamua is a comet. When comets get near the Sun, they spew gases from their interior. This jetting of gas always has some effect on the trajectory of the comet. The amount of change in ‘Oumuamua’s trajectory is consistent with the effect of a comet’s gas jets.

As we have emphasized before, the Bible doesn’t say that Earth is the only place in the universe where God chose to create life. At present, however, there is no credible evidence that there is life elsewhere, although microscopic forms may exist on Mars and some moons in our system. The idea of alien visitation is pure speculation with no evidence to support it.

The Lord tells us how to live in another existence. Read 1 Corinthians 15:35-57 to learn more about it. Waiting for an E.T. to come and whisk you away to a heaven is wishful thinking. Waiting for the Lord to come again has much more promise and much more supporting evidence.

Perseid Meteor Shower Peaks

Perseid Meteor Shower Peaks
In our post yesterday we mentioned that the Perseid meteor shower peaks tonight and tomorrow night August 11-12 and 12-13. Earth is making its annual journey through the trail of debris left by Comet Swift-Tuttle. When those pieces of rock, mostly ranging in size from a grain of sand to pea-sized, enter Earth’s atmosphere at supersonic speeds, they burn up from the heat of friction. We see the streaks as “shooting stars.”

Earth has been passing through the Swift-Tuttle debris since July 17 and will not be clear of it until August 24. So even though the Perseid meteor shower peaks this weekend, it is possible that you might see some of the meteors over the next few days. However, on these two nights, they should be visible at the rate of about one per minute. The best time to see them is after the Moon sets, and the best place is an area free of lights and with an open sky.

Every day anywhere from 100 tons to 1,000 tons of meteoritic material enters the Earth’s atmosphere. This material can come from comets or asteroids. The asteroid 3200 Phaethon produces the Geminid meteor shower in mid-December. There are other pieces of rock, dust, and debris in space that sometimes get trapped in the Earth’s gravitational field, and contribute to the hundreds of tons of material that reach Earth every day.

So what are the lessons we get from all of this? For one thing, Earth is not a static planet. It is gaining new mineral wealth every day. Our planet is vibrant and alive and has changed over the eons of its existence. The design of Earth’s defensive shield is incredible. With all of this material left over from the creation processes, it is critical that we have an atmosphere that is dense enough to burn up the space junk that comes toward us.

Every time scientists get a meteor sample we learn more about our neighbors in space. We knew a lot about the makeup of asteroids before science actually landed a spacecraft on one. Our knowledge of comets was advanced before we were able to leave Earth’s gravity and examine one up close. We continue to learn about the unique nature of the Earth, the Moon, the Sun, and the material that makes up our solar system.

While you are outside, take a look at Mars which is still closer and brighter than usual and visible until about 4 AM local time. Saturn will be visible until 2 AM. Venus will set about 9:30 PM and Jupiter at 11 PM. The planets travel near the ecliptic, the path of the Sun and Moon across the sky, so here’s your chance to enjoy them all. As the Perseid meteor shower peaks, it reminds us of the words of the psalmist: “The heavens declare the glory of God; the skies proclaim the work of his hands” (Psalms 19:1).

Perseid Meteor Shower

Perseid Meteor Shower
One of the most spectacular meteor showers of the year will reach its peak on the nights of August 11-12 and 12-13. This year’s Perseids will be exceptionally brilliant because the moon will be only a small crescent and will set early. You can best see the Perseid meteor shower after 12:00 AM local time.

The Perseids are interesting because they frequently feature a brilliant fireball which can actually cast a shadow or a bolide which is a meteor that explodes. The Perseid meteor shower gets its name from the fact that the meteors appear to come from the direction of the constellation Perseus which will be in the northeast for those of us looking up from the United States. However, you will see them streaking in any area of the sky.

The Perseid meteor shower is debris from the Comet Swift-Tuttle which was discovered in 1862 and returned most recently in November of 1992. These meteors are small particles usually no larger than a pea and as small as a grain of sand. They become visible at an altitude of 55 miles (88 k) where they enter the atmosphere with an average velocity of about 133,200 miles (214,365 km) per hour. Perseid meteors usually burn up by the time they reach an altitude of 50 miles (80 km) and never contact the surface of the earth. If they did, they would be called meteorites.

So, if you can, find a place away from city lights after midnight. Lean back in a lounge chair where you can see the expanse of the sky. The best viewing is with your unaided eyes. Binoculars or a telescope will not allow you to view the whole sky. Then just enjoy the beauty of God’s creation. We will have more on the Perseid meteor shower in our post tomorrow.

Why Such a Huge Universe?

Why Such a Huge Universe?
Here are some questions that are often asked by those who are skeptical of the existence of God: Why such a huge universe? How can we believe that a Creator cares about us when we are so insignificant in this vast cosmos? Those questions are worth considering.

There is no doubt that the cosmos is fantastically large. The Hubble Space Telescope aimed at a small area of sky no larger than one-tenth of the diameter of the Moon to take this Hubble eXtreme Deep Field photograph. The few bright spots with points of light radiating are stars. All the rest are galaxies—more than 10,000 of them in this picture! Some of them are as far away as 13 billion light-years, meaning that they were among the first galaxies formed.

If there are 10,000 plus galaxies in this tiny area of sky, that means there are 200 billion galaxies in the visible universe. Each of those galaxies contains an average of 200 billion stars. So why such a huge universe?

There were two critical factors at the beginning of cosmic existence—mass and expansion rate. If the total mass of protons and neutrons had been any less during the first moments of creation, hydrogen would not have fused into any elements heavier than helium. Then the nuclear furnaces of the stars could not have generated the elements carbon, nitrogen, oxygen, phosphorus, sodium, and potassium, which are essential for life. If the mass of protons and neutrons had been any greater at the cosmic creation, all of the original hydrogen would have fused into heavier elements like iron, and life would not have been possible.

The mass also affects the expansion rate. If the cosmic mass density had been less, the expansion rate would have been too fast to form stars like the Sun and planets like Earth. If the density had been greater, the expansion rate would have slower and all stars would have been much more massive than the Sun and would give off radiation too intense for any orbiting planets to sustain life.

In other words, the universe was fine-tuned from the moment it began! Why such a huge universe? Because it had to be. It has just the right mass and expansion rate for us to be here. We don’t think that was an accident. Through the study of astronomy and astrophysics, we can see HOW God created the universe we live in, and HOW He made it possible for us to live in it. The creation of the universe is not magic. It’s a feat of astounding engineering from the very moment of creation.
