How the Elements Were Crafted

One of the great mysteries of science has been the question of how the heavier elements came into existence. Physicists have produced a few heavy elements in particle accelerators, and they have observed them being made in stars. Understanding how the elements were crafted is a solid apologetic for God’s creative power and wisdom. Being able to duplicate in a laboratory what God has done in the vast outreaches of space increases our amazement at what God has done.

As we said yesterday, the ability to produce nuclear fusion may solve our energy needs, but the fact that God did it “in the beginning” has led to a greater appreciation of God’s power and His methods. We know that the nuclear fusion of hydrogen can produce helium. We can duplicate that process in the laboratory on a small scale and see it in operation in the Sun.

Hydrogen (1) was produced first, but forging elements, including carbon (6), nitrogen (7), and oxygen (8), required enormously high pressures and temperatures in the interior of stars. These elements are the four starting points for life—still heavier elements require even greater pressures and temperatures.

In 1987, astronomers watched a star explode, becoming supernova 1987a. After the explosion, astronomers detected neon (10) in the star, which was not there before. Direct and indirect observations of the nuclei of exploding stars has shown how the elements were crafted as God produced the following 28 elements in the periodic table. This group includes copper and phosphorus, which are present in our bodies and are essential to life.

As our cosmic tools have become capable of detecting gravitational waves, we have seen even heavier elements produced when neutron stars collide. For example, computer models have shown that those collisions can produce the elements gallium (31) through bismuth (83). In addition, the merger of two black holes can produce very heavy elements such as thorium (90) and uranium (92). The bottom line is that we can see how the elements were crafted by God. He made the universe and our bodies from elements produced in the core of ancient stars.

Obviously, the Bible doesn’t explain how the elements were crafted. However, it does tell us that God acted “in the beginning” to set the process in motion. As we observe the universe through new tools such as the Webb Telescope with the help of computers, we can see a vivid display of God’s power and wisdom in creating all that we see and are. For most of us, “In the beginning, God created” is all we need to know, but as science learns what it takes to create the building blocks of creation, we have a whole new appreciation of “the heavens declare the glory of God and the expanse proclaims the work of his hands” (Psalms 19:1 CSB).

Anniversary of a Star Explosion – SN 1987A

Today is the thirty-fourth anniversary of a significant astronomical event. It’s the anniversary of a star explosion. On February 23, 1987, astronomers and other observers on Earth witnessed the explosion of a star with a mass about twenty times that of our Sun. They called it supernova SN 1987A.

The explosion was bright enough to see with the naked eye. While Earth observers saw it in 1987, the explosion happened long before that. Since the star was located in the Large Magellanic Cloud, a galaxy 160,000 light-years from Earth, we witnessed an event that occurred 160,000 years in the past.

There have been other supernovas, but SN 1987A was the brightest supernova observed since the telescope’s invention. It was also the brightest since Chinese astronomers observed a star exploding in A.D. 1054. For the past thirty-four years, astronomers have studied the ring of fire as it expands outward from that explosion. The picture showing the remnant of the explosion is a composite image from 2014. It combines visible light from the NASA/ESA Hubble Space Telescope and x-rays from NASA’s Chandra X-ray Observatory.

What do we learn from our study of the stars, supernovas, nebulae, and everything else we can see in the universe? We learn the processes God used to create the universe, our galaxy, and our planet. As we examine supernovas, we understand that God used them to forge the heavier elements that make up our planet and our bodies.

Studying the creation process also shows us the incredible precision required to make the universe possible and create life on this planet. On this thirty-fourth anniversary of a star explosion, we are reminded of the words of an ancient psalm, “The heavens declare the glory of God” (Psalms 19:1).

Supernova 1987A Celebrates 30th Birthday

On February 23, 1987, a historic explosion was witnessed by astronomers on Earth. A massive star known as Sanduleak -60 degrees 202 exploded. What was previously classified as a supergiant star became a supernova. For the first time since A.D.1054, there was a supernova close enough to the Earth for scientists to observe first-hand what was happening.

Students in high school physics and earth science classes study a diagram known as the Hertzsprung-Russell diagram. It is simply a scattergram of the temperature of stars plotted against their luminosity. Stars begin as very hot blue giant stars. As they cool, they turn white-hot, then red, then brown. Then they may become a cinder. In the case of larger stars, the internal processes change, and they become giant stars which in some cases explode. Because these processes require a very long time, we don’t live long enough to see a single star go through all of these phases. But we can see stars in all of these stages. Seeing a star explode is a very rare event (about once a century), and Sanduleak -60 degrees 202 was thus a fantastic opportunity to see in detail what happens when a star explodes.

There is much to learn from Supernova 1987A. Exploding stars seed space with the heavier elements. We are learning how the elements that make up our world were formed. For those of us who believe God is the engineer of all of this, we can see how God made iron, copper, gold and the materials of the Earth’s crust. The incredible energy and power of the process testify to God’s power and creative wisdom. As we compare this supernova with the one that happened in A.D. 1054, which produced what is now called the Crab Nebula, we see it is different in many ways. In 1 Corinthians 15:41 the Bible tells us that “one star differs from another” and we now know that is true even of exploding stars. This supernova also gives us another tool to measure the size and age of the universe. We have several methods of measuring how far away this supernova is, but they all give us the same answer. The explosion took place 160,000 light years away from us, or 160,000 years ago. We are safe from the incredible radiation because of the huge distance.

We now have 30 years of measurements of this historic explosion. This birthday will be celebrated by scientists, but it is also significant to those who enjoy looking into space and seeing the handiwork of God.
