Did the Universe BEGIN to Exist?

Look at the syllogism in the picture above. Is it logical? Does it make sense? Yesterday, we examined premise 1 and concluded that it is true. However, looking at the second premise could be more challenging. Did the universe BEGIN to exist?

You could assume that the universe has always existed. If it didn’t BEGIN to exist, it doesn’t need a cause! That was the approach of many “thinkers” from Aristotle to Einstein. When Einstein formulated the theory of special relativity in 1905, he was concerned that his formulas indicated that the universe was not in a steady state. It was either expanding or contracting, meaning it could not have always existed. To correct that “problem,” Einstein added a “cosmological constant” that made it appear that the universe is unchanging. He just made up a number so that his equations would show that the universe was eternal. Other scientists realized that Einstein was cheating, and he later admitted it was the biggest mistake of his life.

Scientific experiments from the 1920s to the 21st century have confirmed the universe is expanding and even accelerating in its expansion. Since the universe is expanding, we can trace that expansion back to a point where the universe began as a “singularity.” So, did the universe begin to exist? The answer is yes, it had a beginning! That was something that many scientists did not want to accept because of its religious implications.

British astronomer and atheist Fred Hoyle coined the derisive term “big bang” because his faith would not allow the concept of an ultimate Causer, or God. He used that term to make fun of the idea of a beginning. However, it has now become the popular term for the beginning.

So, if premise 1 and premise 2 are both true, the conclusion must be true. The universe has a cause, and science can’t determine what it is. The scientific consensus is that the big bang was the beginning of time and space as well as matter and energy. So, what does that tell us about the Cause? It tells us that the Cause has to be non-material and outside of time and space. What fits that description? We will examine that next time.

Why Does the Universe Exist?

Yesterday we questioned, “Why does the universe exist?” So, why is there anything now if nothing existed before the cosmic creation event or big bang?

We can say that everything exists because God exists. God chose to create this fine-tuned universe of space, time, matter, and energy. We can summarize this with a simple logical statement known as a syllogism. If the first and second premises are correct, then the conclusion must be true.

Premise 1- Everything that begins to exist must have a cause.
Premise 2- The universe began to exist.
Conclusion- The universe has a cause.

Premise 1 seems to be obvious. If something did not exist and then came into existence, it must have a cause for its existence. For example, suppose you are driving down the street and notice an empty lot. Each time you drive by, there is nothing but grass growing there. You take a different route for a few months, but one day you drive down that same street, and there is a house on the lot. You would not conclude that the house appeared there without a cause.

You would logically conclude that some builders constructed that house for a reason–probably because someone wanted to live there. You could investigate to learn the identity of the occupants. You could even explore building methods to see how the house was constructed. However, you would surely not conclude that the house appeared out of nothing with no cause.

Why does the universe exist? Did it BEGIN to exist? I think that a reasonable person would be willing to accept premise 1. Tomorrow, we will examine premise 2.

Something from Nothing Does Not Make Sense

How can you get something from nothing? Most scientists today agree that the universe had a beginning. They disagree on how it began, but they largely accept the idea that it began to exist. However, another question many ask is, “Why does anything exist?” If there was nothing before the universe began, why are we here? If nothing existed before the universe began, it is difficult to explain why there is anything at all.

Some have tried redefining “nothing” to make it “something.” Sometimes they suggest that something is gravity. So, if gravity existed before there was anything, where did the gravity come from? What they are doing is to substitute gravity for God, but how can there be gravity without mass?

Isaac Newton described gravity as the attraction between objects that have mass. The more mass, the more gravity pulls them together. That was the accepted theory until Einstein devised a new idea. His theory defined gravity as a curvature in space-time, which is the accepted concept today. But, according to scientists, the cosmic creation event (usually referred to as the big bang) was also the beginning of space and time. So, where does gravity come from if there is no space-time or matter-energy? That still does not answer the question, “Why does anything exist?” You can’t get something from nothing.

Of course, if science says that gravity existed before anything else, atheists argue that it is no different from saying that God existed before anything else. Who or what made God? Everything that begins to exist must indeed have a cause. However, God is eternal. He did not begin to exist. God is the first cause, the unmade Maker, the necessarily existing uncaused Being. If God created time and space, He is outside of time and space.

God existed before time, but even using the term “before” shows that we are limited to thinking in time terms. There is no before or after with God. He knows the future because He can see the entire timeline of the cosmos, viewing it from the outside.

So back to our original question, “Why does anything exist?” We will look at that tomorrow.

Why Does Anything Exist?

Why is there something rather than nothing? Most scientists today agree that the universe had a beginning. They disagree on how it began, but they largely accept the idea that it began to exist. However, another question many ask is, “Why does anything exist?” If there was nothing before the universe began, why are we here?

If nothing existed before the universe began, it is difficult to explain why there is anything at all. Some scientists have tried redefining “nothing” to make it “something.” Sometimes they suggest that something is gravity.

So back to our original question, “Why does anything exist?” We can say that everything exists because God exists. God chose to create this fine-tuned universe of space, time, matter, and energy. Since God is outside of time, He can hear the prayers of millions of people all over the world at the same time. There I go using that “time” word again. We can’t think outside of time because we can’t live outside of time. If we could, for just a moment (another time word), step outside of history’s timeline and see it from God’s perspective, we could understand why God allows things to happen. We could understand the things that make us ask, “Why doesn’t God stop that from happening?” We could see the conclusion of all things. We would know that because of God’s wisdom, justice, and love, the conclusion is good.

The Unique Design of Our Solar System

We have pointed out that recent reports from NASA reveal that astronomers have found more than 5000 planets orbiting stars other than our Sun. These extra-solar planets show that our solar system is a rarity in space. The unique design of our solar system strongly supports the idea that it is a product of intelligent creation, not a cosmic accident.

One might suggest that having a life-bearing planet is like trying to shoot something. If you shoot enough times, you will eventually hit the target. So likewise, if we find enough planets outside of our solar system, we will ultimately find one like Earth that can support life and even beings like ourselves. However, recent discoveries show that our solar system is so unique that it cannot be a chance production.

One discovery from the observation of exoplanets is the uniqueness of having a rocky planet orbiting this far from a star. In a study of 169 detected and confirmed rocky planets orbiting nuclear burning stars, more than 90% of them orbit their stars ten times more closely than Earth orbits the Sun. Being closer to their stars would mean that the lighter elements in those planets would be burned away, so those planets should be denser than our rocky planets. However, the data shows the exoplanets have a density of 4.472 grams/cc, while Mercury, Venus, and Earth are 5.395 grams/cc. What does this fact suggest?

The starting point for interpreting this data is the Sun. It has a very unusual lack of refractory elements (those elements which boil easily). That is especially true of lithium which is 170 times lower in abundance in the Sun than in the rest of the solar system. Scientists have advanced various theories about why that is, but it means that the Sun’s flaring activity is at a very low level compared with similar stars. Thus the Sun has an exceptionally low level of harmful ultraviolet and X-ray radiation.

As we look at rocky extra-solar planets orbiting other stars, we see they are very close to their stars. Since the stars would burn off the light elements with low boiling temperatures, we would expect to see rocky material left behind. The fact that our Sun has rocky planets that are farther away is because of the Sun’s unusually low levels of refractory elements and low levels of ultraviolet and X-ray radiation.

Other factors about exoplanet systems demonstrate the unique design of our solar system. For example, Earth’s chemical composition is unique. The extra-solar planets scientists have studied do not have the chemicals needed in the amounts required for advanced life forms to exist. Also, our Moon plays an essential role in the system that allows Earth to retain its atmosphere and hydrosphere.

With more data from astronomers studying extra-solar planets, it becomes increasingly clear that our Sun and our solar system are not typical products of accidental chances in space. The number of parameters that our unique solar system possesses speak of design. The unique design of our solar system shows that God’s creative hand has done much more than we imagined. This shows the truth of the old cliche that “the more we know of the creation, the more we appreciate the role of the Creator.”

Known Exoplanets Number 5009

As new space telescopes look out into the cosmos, astronomers discover more planets orbiting stars other than our Sun. NASA reports that known exoplanets number 5009. The process God used to create “heaven and earth” resulted in a lot of extra material in various forms throughout the cosmos. In 1999, astronomers discovered the first exoplanet, and since then, the number has kept growing.

At first glance, one might feel that since there are so many planets, some of them must be inhabited by sentient beings like ourselves. However, we find that is not the case when we examine the breakdown of the types of planets that astronomers have discovered. Even though known exoplanets number 5009, only 200 are worlds like Earth, made up of solid rock. The rest are gas planets like the Jovian planets Jupiter or Neptune, or they are huge solid planets with massive gravitational forces that would crush living beings. We should remind you that a world suitable for sentient life requires at least 47 other variables that we have listed in a chart you can see at THIS LINK.

When God “created the heavens and the earth” (Genesis 1:1), His methods involved forging massive amounts of gases and very few solid materials. Known exoplanets number 5009 now, but the number is sure to increase. Studies continue to show that our solar system and planet are unique. God’s wisdom in creating Earth the way He did becomes more evident as we explore space and realize how many resources we have available on this planet.

The “heavens declare the glory of God and the sky shows His handiwork” (Palms 19:1). We see more of His power and wisdom as our technology produces better images of the cosmos and how it was created in the beginning.

Medical Challenges of Space Travel

Space exploration presents many challenges, but the medical challenges of space travel may dwarf the technical challenges. Spending lengthy sojourns on the International Space Station (ISS) has already shown some of the problems that future space travelers will face.

One problem astronauts face is space anemia caused by a lack of red blood cells. On Earth, the human body makes two million red blood cells every second to replace the ones that are lost. In space, the astronauts’ bodies lose three million red blood cells each second, and they must replace those cells. Anemia results from a shortage of the red blood cells needed to carry oxygen to all parts of the body. It causes fatigue, dizziness, and weakness.

Space anemia was well-known, but scientists thought the body would adapt and correct the problem after an extended time in space. Unfortunately, a recent study of 13 astronauts has shown that it is not corrected after six months on the ISS. Furthermore, it took three to four months to restore a near-normal red blood count after the astronauts returned to Earth. There was still a thirty percent greater loss of red blood cells even after that.

A new study on cosmonauts in the ISS shows another area of concern. Scientists studied the brains of twelve cosmonauts just before and after their space flights and again seven months after they returned to Earth. They used computer reconstruction of data from magnetic resonance imaging (MRI) to study the structure (gray matter) and connectivity (white matter) in the brain. The research showed shape changes in the brain, especially in the corpus callosum, a large bundle of nerve fibers that connect the brain’s two hemispheres. In addition, researchers detected “changes in the neural connections between several motor areas of the brain.” But, perhaps, the most concerning is that in the brain scans taken seven months after the cosmonauts returned to Earth, the changes to the brain were still present.

A journey to Mars and back will take more than twenty months. During that space flight, astronauts will need protection from radiation, food for proper nourishment, and to replenish red blood cells while they experience “rewiring” of their brains. The many medical challenges of space travel remind us how blessed we are that God has given us the perfect planet to call home.

Methane and Life on Other Planets

Astronomers are constantly looking for signs of life on other planets or moons. One of the potential clues they seek is methane, a hydrocarbon gas consisting of one carbon atom and four hydrogen atoms. It is classified as a “greenhouse gas” because it can trap heat on Earth’s surface resulting in “global warming.” It’s a more effective greenhouse gas than the much-discussed carbon dioxide. Methane is produced by organic decomposition and in the digestion process of ruminants such as cows and other animals. Scientists seek to learn more about a possible connection between methane and life on other planets.

Since living things create methane, scientists regard it as a potential “biosignature” indicating life on an astronomical body. For that reason, astronomers are searching for methane on planetary bodies. News reports have sometimes gone overboard with stories about methane and life on other planets. However, not all methane is created biologically. Volcanic eruptions can release methane gas, and even asteroid impacts can add methane to a planet’s atmosphere. So how can scientists tell if the methane is a sign of life on a body far out in space?

For one thing, gasses from a volcano would contain not only methane but also carbon monoxide. The biological creation of methane would consume carbon monoxide. When examining the gasses in a planet’s atmosphere, a large amount of BOTH methane and carbon monoxide would probably indicate that the methane was not a biosignature. Methane alone would be a more likely indicator of the possibility of life.

However, an abundance of methane without carbon monoxide would not prove the existence of life on a planet. As we have said before, many factors are required to make a planet suitable for any kind of life, especially advanced life. NASA’s James Webb telescope, launched in December, is still working to reach full functionality. When it does, a significant part of its purpose will be to look for methane in the atmosphere of exoplanets.

When results indicate that the Webb telescope has detected methane on a planet, news reporters may sensationalize the facts to suggest more than they deserve. Reputable scientists are more cautious in their predictions about methane and life on other planets. Nevertheless, we are excited about the possibility of learning more about the universe with the new Webb space telescope.

As we have said before, the Bible doesn’t tell us if there is life on any other object in space. If there is, we believe that God put it there. We are not afraid of scientific investigation because the more we learn about the creation, the more we stand in awe of the Creator.

Return of the Lyrid Meteor Shower

In late April each year, we see the return of the Lyrid meteor shower. It may not be the most spectacular meteor shower of the year, but I find it easier to observe. That’s because, in our part of the world, it comes at a time when the weather is mild enough to sit outside and watch (unlike the Geminids in December) and before mosquitoes become a problem (as with the August Perseids shown in the picture).

This year, the return of the Lyrid meteor shower is from April 14-30, with the peak on the night of April 22. Typically, the Lyrids display five to 20 meteors per hour at the peak, although, in some years, the number has been higher. Written records of the Lyrid meteor shower go back 2700 years when Chinese astronomers made note of it in 687 B.C. A Korean account from A.D.1136 says that “many stars flew from the northeast.”

If you see the Lyrid meteor shower, you will not be looking at falling stars, although you may get that impression. Instead, you will see tiny fragments of Comet Thatcher (officially C/1861 G1), discovered in 1861 by amateur astronomer A.E. Thatcher. That year was the last time the comet flew by our planet at 31.1 million miles (50.1 million km). Its next return to our vicinity will be sometime around the year 2280. Meanwhile, Earth’s orbit around the Sun causes us to pass through debris the comet left behind. So we see those fragments as they burn up from the effect of atmospheric friction.

We live in an orderly universe on a planet positioned to allow observation and study of the cosmos. Our planet is designed with an atmosphere and magnetic field to protect us from comet debris, meteorites, cosmic rays, and solar wind. If you have the opportunity to observe the return of the Lyrid meteor shower, use it as a time to thank the Creator for allowing us to live in the just-right time on a just-right planet in a just-right location in the universe.

The Size of the Cosmos

We have often mentioned NASA’s Astronomy Picture of the Day (APOD). Their March 16, 2022, post showed the above diagram of the OBSERVABLE universe. The emphasis on the word observable is because astronomers have realized that what we can see is only part of the creation. Our technology allows us to appreciate the size of the cosmos. When you look into space with today’s most powerful telescopes, you can see far beyond our Milky Way galaxy.

We can observe that there are billions of galaxies with different shapes, and each contains billions of stars. However, visible light is limited. Just as the light from a lightbulb appears less bright as you move further away from it, visible radiation from distant objects becomes dimmer the farther away they are. As a result, science has developed new instruments to see radiation other than visible light, such as Xrays and microwaves. In addition, we now have devices that can detect neutrinos and gravitational waves from objects still farther away.

Everything we can detect operates by the same physical laws that govern our own tiny part of space. So any suggestion that there could be universes with different physical laws and physical constants is pure speculation.

The more we learn about the size of the cosmos as we use improved instruments, the more obvious it becomes that the creation is too vast for us to comprehend. The cosmos speaks of design, power, and creative expression beyond what our technology can perceive.

The NASA website reveals higher dimensions, and the size of the cosmos speaks to us of a God beyond our comprehension. In the words of Psalms 19:1, “The heavens declare the glory of God and the skies show his handiwork.”

On Wikimedia, you can see the above logarithmic illustration with annotations identifying the objects. In addition, you can find some of our previous APOD references HERE, HERE, HERE, and HERE.
