Hubble Constant and Gravitational Waves

For years, many scientists were reluctant to accept that the universe had a beginning. Looking through a telescope in the 1920s, Edwin Hubble observed that other galaxies were moving away from us. Going back in time, this suggests that at some point, they were much closer together. If we go far enough back, all matter and energy in the universe would have started from a single point called a singularity. For years, many scientists dismissed this idea, and Fred Hoyle mockingly named it the “big bang.” This leads us to the Hubble constant and gravitational waves, but I am getting ahead of the story.

In 1964, Arno Penzias and Robert Wilson accidentally discovered the Cosmic Microwave Background radiation (CMBR or CMB), which is leftover from the cosmic creation event (aka “big bang”). The CMB scientifically proved that the universe had a beginning. Further evidence in the 21st century made it impossible to deny that the universe had an origin. Since 1998, science has shown that the universe’s rate of expansion is accelerating. They hypothesize a mysterious force called “dark energy” to explain this acceleration, even though they have never detected this mysterious force.

To measure how fast the universe is expanding, scientists look for what they call the Hubble constant. They have two methods for measuring it: one involves using supernovae, and the other is based on physics principles within the standard model of cosmology. Explaining these methods is beyond the scope of this discussion, but the key issue is that they produce different results. This discrepancy is known as the “Hubble tension.” This leads us to a connection between the Hubble constant and gravitational waves.

In a March 2026 research paper, scientists from the University of Illinois Urbana-Champaign and the University of Chicago have proposed a third way to measure the Hubble constant using gravitational waves. Albert Einstein’s 1915 theory of general relativity predicted gravitational waves, but they remained undetected for a hundred years. Then, in 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States detected a gravitational wave for the first time. Since then, with international collaboration, more detections have followed.

Gravitational waves are produced by the collision and merging of black holes or neutron stars. The new theory suggests that by measuring the speed at which these collisions are moving away from us, it may be possible to determine the Hubble constant more precisely. Achieving this will require more sensitive gravitational wave detectors than the current ones. According to Daniel Holz at the University of Chicago, this could help us “learn more about the age and composition of the universe.”

The Hubble constant and gravitational waves give us new insights into creation. Ever since science was compelled to accept that the universe had a beginning, we have learned more about the power and wisdom of the Creator. The more we discover, the more we realize we can know there is a God through what He has made (Romans 1:20).

The Reason for a Multiverse Hypothesis

Science fiction writers love multiverses, and so do many scientists. In science fiction stories, characters step through a portal and emerge in a parallel or inverted world. In the minds of some physicists, multiple universes exist in what is known as the multiverse hypothesis. According to that hypothesis, an almost infinite number of universes exist, each with radically different physical laws and properties. There is no evidence for this, and it is impossible to prove or falsify. So, what is the reason for a multiverse hypothesis?

Agnostic scientists who theorize a multiverse do so not because of evidence but because they cannot explain the apparent fine-tuning of the universe. Why are the particle masses and force strengths in our universe perfectly fine-tuned for us to be here? Slight changes in any of those factors would make it impossible for life to exist and likely for a universe with stars and planets to form.

Speculation about “bubble universes” in a frothing multiverse is pure science fiction at present, so what about another option? Some have proposed an idea based on quantum mechanics. This theory of particle physics states that particles can exist in a “superposition” of possible states until someone measures the particle’s position, at which point it collapses into a single state. It’s difficult to see how this could explain alternate universes, since quantum theory deals with the very small, not entire universes. That brings us back to the reason for a multiverse hypothesis. But, wait! Isn’t there another possible explanation for the fine-tuning of our universe?

Yes, there is another possible explanation for the astonishingly fine-tuned parameters of our cosmos. However, it is one that many stubbornly refuse to accept, or even consider. What about the possibility that the universe was designed by an infinite Intelligence that exists outside of time and space? Isn’t that a more reasonable explanation for the precise design that makes our existence possible?

Quantum fluctuations can’t explain it. Even an infinite number of universes could not explain how we happen to be lucky enough to live in a universe with the right combination of all the exact factors needed for life. Luck and chance are not scientific explanations. Even if there were an almost infinite number of universes, there would still need to be an explanation of how they originated. The design we observe in the cosmos can best be explained by a Designer. Isn’t the only reason for a multiverse hypothesis the desire of skeptics to avoid the most obvious and logical explanation?

Irresponsible Comments About Dark Matter

We are seeing some irresponsible comments about dark matter in both religious and secular articles. The fact is that dark matter is a designed feature of the cosmos and demonstrates the Creator’s wisdom.

The story of dark matter begins nearly 100 years ago when a Swiss astronomer named Fritz Zwicky observed that the Coma Cluster of galaxies contained galaxies moving so fast that they should have flown apart. About 40 years later, American astronomer Vera Rubin noticed that stars along the edges of spiral galaxies were moving so fast that centrifugal force should have sent them flying into intergalactic space. In recent years, astronomers have observed gravitational lensing—the bending of light by gravity—in regions of space without visible matter. These facts point to the presence of unseen or dark matter.

Despite these irresponsible comments about dark matter, it is not where hell is located. It is not a product of celestial evolution and will not destroy the Earth, at least not in the next 1000 years. It is simply a designed feature that allows us to live on this planet in the solar system within this galaxy.

What would the universe look like if dark matter did not exist? Galaxies would need to be much larger to prevent them from collapsing into their centers due to gravity. If you visit NASA’s daily website apod.nasa.gov, you will see that space is full of galaxies. That would not be possible without dark matter.

Psalms 19:1 finds David looking at the sky, unobstructed by modern lights, and stating, “The heavens declare the glory of God; the skies proclaim the work of His hands. Day after day, they pour forth speech; night after night, they reveal knowledge.” That was true in the clear skies David could observe, and it remains true today as astronomers use modern telescopes to see God’s wisdom displayed in the heavens.

Milankovitch Cycles and Life on Earth

It should come as no surprise that the amount of sunlight reaching our planet influences our climate. Serbian mathematician and astronomer Milutin Milankovitch theorized that fluctuations in Earth’s climate are caused by changes in the amount of sunlight the planet receives, and that these changes follow specific cycles. Milankovitch calculated these cycles over the last 600,000 years and suggested they are responsible for ice ages and subsequent warmer interglacial periods. Geologists examining sediment layers in areas that were once ancient ocean beds confirmed the existence of Milankovitch cycles.

The amount of sunlight reaching Earth depends on three parameters that change over long time scales: the tilt of Earth’s axis, the eccentricity of its orbit, and the precession (wobble) of its axis. Because of the tilt of Earth’s axis, we experience seasons. Earth’s orbit is nearly circular but slightly elliptical, so its distance from the Sun varies. The precession of Earth’s axis is a slight wobble over time, similar to the wobbling of a spinning top.

Earth’s orbit is more circular than those of any other planet in our solar system. Because of this, the length of our seasons is approximately equal, but over long periods, these can change. The tilt of our planet’s axis is 23.4°, but it has varied in past ages from 22.1° to 24.5°. The precession of Earth’s axis also shifts over extended timescales. All three factors influence Earth’s climate because they alter the amount of sunlight reaching its surface.

The climate changes driven by these three factors are known as Milankovitch Cycles. The mathematician/astronomer calculated these cycles, and geologists have confirmed his calculations through examination of sediment layers from ancient ocean beds. The last Ice Age occurred about 20,000 years ago, when woolly mammoths roamed on ice sheets covering much of North America, Europe, and Asia. Over the past 10,000 years, the climate has remained remarkably stable, enabling the development of advanced civilizations.

As scientists study exoplanets beyond our solar system, they seek to determine their Milankovitch cycles because these cycles are another critical factor in assessing whether a planet can support advanced life. Mars has Milankovitch cycles that are far more extreme than Earth’s, which limits its potential to sustain life. Without the stabilizing influence of our relatively large Moon, Earth’s axis could oscillate up to 30°, leading to severe climate fluctuations. The more we learn about our unique planet, the more evident it becomes that God has finely tuned it to meet all our needs.

Habitable Worlds Observatory

In a quest to detect life on a planet outside of our solar system, NASA has awarded three-year contracts to seven different companies to address the engineering challenges of a new precision space telescope. Since 2022, the James Webb Space Telescope has been capturing images of the universe in infrared light. Prior to that, the Hubble Space Telescope provided us with a deeper understanding of the secrets of space in the visible-light spectrum. The Habitable Worlds Observatory (HWO) is designed to pursue a different goal.

The HWO will be NASA’s most powerful space telescope, aiming to find signs of life in the universe. It will analyze light passing through the atmospheres of distant planets orbiting stars hundreds or even thousands of light-years away. Doing this will require a coronagraph thousands of times more powerful than any built before. A coronagraph is an instrument that blocks out the light from the Sun or other stars to reveal the faint atmospheres of exoplanets. It must also be repairable in space if any stray micrometeoroids impact its surface. The optical system must be stable within the width of a single atom. The precision required for the Habitable Worlds Observatory telescope surpasses any current technology.

This telescope must be far more advanced than the Webb Space Telescope, and you may recall the challenges and costs associated with that project. The goal is to have the Habitable Worlds Observatory ready for launch by the late 2030s or early 2040s. Jared Isaacman, the NASA administrator, stated that this is “exactly the kind of bold, forward-leaning science that only NASA can undertake.”

If the project succeeds in demonstrating that life could potentially exist on a planet outside our solar system, what then? If the planet is thousands of light-years away, we would be observing what it was like thousands of years ago. It will also take that long for us to beam a message to it, and if there are intelligent beings there, it will take an equal amount of time for them to respond. Traveling to such a planet would take humans many times longer, since it’s impossible to travel faster than a small fraction of light speed. Furthermore, even if we see signs that life could exist on a distant planet, we still won’t know for sure if life actually does.

One thing we can be certain of is that the project will take a lot of time and cost a lot of money. However, Isaacman says, “We intend to move with urgency.” In other words, there is an “urgent” desire to find out if there is life or any sentient beings beyond our planet. The truth is, there is a Being out there who has communicated with us, and He has even come to our planet to show us how to live and to redeem us from our sins. Perhaps the greatest urgency is for us to communicate with and come into a right relationship with Him.

Controlling the Sun

The Sun has been very active lately, with sunspots and solar flares, causing auroras to be visible farther south in the Northern Hemisphere. People have enjoyed seeing the colors of the Aurora Borealis, but engineers and scientists are worried about potential effects on satellites and power grids. As we approach the peak of the 11-year solar activity cycle, some are concerned about controlling the Sun.

The truth is that our Sun’s radiation bursts are 10 to 100 times weaker than what scientists have observed from similar stars in the Milky Way galaxy. Why is it that planets we have detected orbiting other sun-like stars might be exposed to deadly radiation that we are protected from? One study by scientists at the German laboratory Helmholtz-Zentrum Dresden-Rossendorf suggests that Venus, Earth, and Jupiter may be partially responsible for controlling the Sun.

The Sun is most active when its magnetic field is strongest, and the idea is that the gravitational pull of Venus, Earth, and Jupiter creates a tidal force that affects the Sun’s magnetic field. The Sun’s magnetic dynamo generates its magnetic field, while the subtle gravity of these three planets may produce a tidal effect. This may make the Sun’s activity “much more benign than that of other sun-like stars,” according to physicist Frank Stefani and his colleagues.

We’ve often said that many factors need to be just right for our planet to support life. This may be another factor to consider. The research team noted that every 11 years, the tidal forces of these three planets align in a way that could influence the Sun’s magnetic dynamo. They admit there are still “missing pieces in our synchronizing jigsaw,” so more research is needed before definitively claiming that these planets are a factor in controlling the Sun. Nevertheless, the fact is that our Sun’s radiation eruptions are 10 to 100 times weaker than those of similar stars. This suggests our planetary system is not accidental but intentionally designed for life.

Space Travel Brain Shifting

Space travel can change your brain in more ways than one. We have mentioned the “overview effect” that people experience when looking down on planet Earth from space. It can open a person’s mind to the realization that we are small and that we depend on the components for survival that God has provided on this planet. New research indicates that space travel and weightlessness can also affect your physical brain. You could call it space travel brain shifting.

Brain MRI scans of 26 astronauts and 24 non-astronauts, conducted by Rachel Seidler and others at the Massachusetts Institute of Technology (MIT), revealed how microgravity affects human brain anatomy. Their research showed that the astronauts’ brains shifted backward and upward while also rotating upward. The effects could still be detected months after returning to Earth. They analyzed MRIs from 15 astronauts before and after spaceflight, and from 11 others after returning. Twenty-four other volunteers participated in a long-duration head-down tilt bed experiment.

There was a measurable change in how the astronauts’ brains fit inside their skulls depending on how long they spent in space. The maximum displacement was 2.52 millimeters. The bed rest control group did not show marked changes. The question is how the space travel brain shifting affects performance after returning to Earth. The astronauts did experience balance issues, apparently due to effects on the inner ear and sensory regions of the brain.

The bottom line is that the study showed that physical shifts in the astronauts’ brains lasted up to six months. The study is concerned about “the long-lasting effects of spaceflight on neuroanatomy.” Again, we are reminded of how much we depend on the components for survival that God has provided on this planet.

Water Stewardship in America

What is the most vital compound for human survival on Earth? The answer is water. We see water shortages in underdeveloped countries, and we know that water was a major concern for every nation in ancient times. The Roman government built massive aqueducts to transport water to its people, and ancient Israel’s kings survived by constructing tunnels and digging wells. How is our water stewardship in America?

How much water does it take to run an average home in America? The answer is 109,500 gallons per year, according to the U.S. Environmental Protection Agency. The University of Montana reports it takes between 109,000 and 136,000 gallons of water to produce a ton of alfalfa hay for cattle feed. One gallon of milk requires 1000 gallons of water, but most of that goes toward growing the cattle feed. Producing a quarter-pound hamburger patty consumes 450 gallons of water, most of which is used to feed and water the cattle.

A significant portion of the water used in agriculture comes from wells in the Midwest, known as the “grain belt.” The Cambrian-Ordovician deep sandstone aquifer underlies this region. According to Wikipedia, “The water from the aquifer is being pumped up and drained by agriculture, commercial, and residential use that is unsustainable.” Many wells are drying up, and additional wells are being drilled deeper to meet the demands.

God told Adam, “Take care of the garden, dress it and keep it” (Genesis 2:15). Recently, humans have not been following that command. In some areas, injection wells are used to dispose of waste, often injecting it into the same aquifers that supply our drinking water. Can we become more efficient in our water use? There’s no doubt that we need to.

The teachings of Christ urge us to serve and care for others. Providing food and water to those in need is part of that. Christianity isn’t about church buildings or political activism. Taking care of the garden involves responsible water stewardship. God has given us the resources and wisdom to address this issue. We must live out Christian principles of love and service to others, and humanity’s future survival depends on teaching these principles to our youth.

Planet Earth is a Very Special Place

People often dream of leaving Earth and exploring or establishing residency elsewhere in the universe. Whether it is Star Wars, Star Trek, or The Martian Chronicles, entertainment media suggest that soon, humans won’t be limited to the planet on which we were born. What these people may not realize is that planet Earth is a very special place, carefully designed to support and protect life from deadly forces.

The Sun provides the heat, light, and energy essential for life on Earth, but its nuclear processes also release energy that can be harmful. Stars in other parts of our galaxy emit radiation capable of ionizing atoms in living cells, destroying them. Some of these radiation forms can be easily blocked—beta and alpha particles can be stopped by plastic, glass, or aluminum. But higher-energy radiation, like gamma rays, X-rays, and high-energy particles such as protons, neutrons, and HZEs (high-energy ions), requires heavy shielding like lead, concrete, or thick layers of water. Of course, building shields of such materials around a spaceship isn’t practical.

Scientists are exploring ways to use magnetism or exotic energy sources to solve this problem—and they may succeed someday. The point is that planet Earth is a very special place, beyond what most people understand. The author of the Genesis account had to describe creation in a way ancient shepherds could understand, yet one that scientists in 2026 couldn’t dismiss as just an old myth.

Genesis 1:1 in Hebrew reads, “reshith elohim bara shamayim erets.” The ancient shepherd would read “In the beginning God created the heavens and the Earth.” A scientist reading these words in 2026 would understand that the author was describing a beginning to time, caused by an intelligence outside of space and time, that created a planet with water so carbon-based life could live on it.” Planet Earth is a very special place.
