When Biblical Interpretation, Scientific Evidence, and Conspiracy Theories Collide
There is something remarkable happening across social media. An increasing number of people are promoting the belief that Earth is flat, enclosed beneath a solid dome called the firmament, and that everything we’ve been taught about space is an elaborate deception. Even more remarkable is that many are using the Bible to support these claims.
Recently, videos of SpaceX rocket launches have circulated showing enormous, glowing formations in the sky. These formations, sometimes called space jellyfish, are being presented as evidence that rockets are striking the firmament and exploding against an impenetrable barrier. The explanations are often delivered with extraordinary confidence. But confidence is not evidence.
And perhaps more importantly, believing something is biblical does not automatically mean our interpretation of the Bible is correct. As Christians, we should be particularly careful about that distinction.
What Does the Bible Actually Say About the Firmament?
The discussion begins in Genesis. Genesis 1:6–8 describes God creating a vault to separate the waters above from the waters below. The King James Version uses the word firmament, while the New International Version uses vault. The original Hebrew word is raqia (רָקִיעַ).
The word comes from a Hebrew root associated with spreading out, extending, or beating something into a broad surface. This is where understanding the original language and historical context becomes important. Ancient Near Eastern cultures commonly envisioned the heavens as a great vault extending above the Earth. Some understood that vault as a solid structure separating the inhabited world from celestial waters.
The Hebrew description in Genesis reflects elements of that ancient cosmological understanding. In fact, respected Hebrew lexicons recognize that raqia could refer to a solid expanse. Biblical scholars have debated whether Genesis describes a physically solid vault or whether the language should be understood more broadly as the visible heavens.
That debate deserves serious consideration. What it does not justify is the assumption that a physical dome surrounds our planet today. Understanding how ancient people described the heavens is not the same as proving that their understanding represented the physical structure of the universe.
The purpose of Genesis is to establish God as the Creator and sovereign authority over creation. It tells us that the universe is not an accident outside God’s authority. But should we expect Genesis to function as a modern textbook of astronomy, atmospheric physics, or orbital mechanics? That is a very different question.
The Danger of Reading Modern Assumptions Into Ancient Scripture
One of the most common mistakes in biblical interpretation is called eisegesis. Eisegesis occurs when we read our own assumptions, beliefs, or desired conclusions into a passage rather than drawing meaning from the text itself. Consider what happens when someone begins with the belief that Earth must be flat.
Suddenly, every reference to the Earth’s foundations becomes proof that it cannot move. Every mention of the heavens being stretched out becomes evidence of a dome. Every reference to the ends of the Earth becomes a geographical boundary. And every unusual phenomenon in the sky becomes evidence that the dome exists. But this is not careful biblical interpretation. It is selecting passages that appear to support an established conclusion.
The Bible contains historical narrative, poetry, prophecy, wisdom literature, parables, and apocalyptic imagery. These literary forms do not always communicate in the same way. When Psalm 91:4 describes God covering His people with His feathers and providing refuge beneath His wings, we do not conclude that God is literally a bird. We understand the imagery.
Likewise, when Scripture speaks of the foundations of the Earth, we must consider whether the passage is describing physical geology or communicating stability, order, and divine authority. Taking the Bible seriously requires taking its language, context, and literary form seriously. Literal interpretation is not always faithful interpretation.
Does Isaiah 40:22 Teach a Flat Earth?
One passage frequently mentioned in discussions about Earth’s shape is Isaiah 40:22. The NIV describes God as enthroned above the circle of the Earth. Some flat-Earth proponents argue that a circle is not a sphere, and therefore Isaiah supports a flat, circular world. Others argue that the passage proves the Earth is spherical. Both interpretations risk demanding more from the passage than its language establishes.
The Hebrew word chug can describe a circle or curved boundary. By itself, it does not establish whether Isaiah intended a flat disk or a three-dimensional sphere. The passage emphasizes God’s greatness over creation and the relative smallness of humanity. It is not presenting a mathematical definition of Earth’s geometry. Interestingly, Job 26:7 describes God suspending the Earth over nothing. That passage has sometimes been presented as evidence that the Bible anticipated modern astronomy. However, we should apply the same interpretive standards consistently.
We cannot insist that poetic language is literal scientific revelation when it supports our argument and then dismiss other poetic descriptions when they do not. The stronger approach is to recognize what the biblical authors were communicating within their historical and literary contexts.
Scripture does not need to be transformed into an astronomy textbook to retain its theological authority.
What Does Science Tell Us About Earth’s Shape?
Long before NASA, SpaceX, satellites, or modern governments existed, people had already discovered compelling evidence that Earth is spherical. Ancient Greek thinkers observed the movement of celestial bodies, the changing positions of stars, and Earth’s shadow during lunar eclipses. More than two thousand years ago, Eratosthenes used differences in the Sun’s apparent position at two locations to estimate Earth’s circumference. He accomplished this without satellites, computers, or space travel.
The principle was straightforward. If sunlight strikes two locations at different angles at the same time, those differences can help reveal the curvature of the Earth’s surface. Modern measurements have refined our understanding. Earth is not a perfect sphere. It is approximately an oblate spheroid, slightly wider around the equator than from pole to pole.
And we do not have to rely exclusively on photographs taken from space to establish this. Consider several observations.
1. Lunar eclipses
When Earth passes between the Sun and Moon, Earth’s shadow falls across the lunar surface. That shadow is consistently curved. A spherical Earth naturally explains why its shadow remains circular regardless of the orientation from which it is observed.
2. Different stars are visible at different latitudes
As someone travels north or south, the visible night sky changes. Polaris, the North Star, rises higher in the sky as an observer travels north. Eventually, when traveling sufficiently far south, Polaris disappears below the horizon. This is consistent with observers standing on different parts of a curved surface.
3. Ships disappear below the horizon
As ships travel away from an observer, their hulls disappear before their upper structures. This is not simply a matter of objects becoming too small to see. Earth’s curvature progressively obscures the lower portions of distant objects.
4. Time zones and the day-night cycle
When it is afternoon in Ohio, it is nighttime in other parts of the world. A rotating spherical Earth illuminated by the Sun explains the predictable progression of daylight and darkness across the planet.
5. Navigation and orbital technology
Modern navigation, satellite communications, geodesy, and orbital calculations operate using mathematical models that account for Earth’s shape and gravitational field. These systems produce measurable, repeatable results. The evidence for Earth’s curvature is not dependent upon trusting a single government agency. It comes from centuries of independent observation, measurement, and practical application. And that brings us to the latest controversy.
Are SpaceX Rockets Exploding Against the Firmament?
Recently, videos of SpaceX launches have generated renewed claims that rockets are colliding with an invisible dome. The footage shows a rocket ascending into the sky, followed by an enormous glowing formation resembling a jellyfish.
Some viewers interpret the expanding cloud as an explosion caused by the rocket striking a solid barrier. But the phenomenon has a well-established scientific explanation. It involves atmospheric pressure, rocket exhaust, sunlight, and the position of the observer.
As a rocket climbs, the surrounding atmospheric pressure decreases. The gases leaving its engines expand more dramatically at higher altitudes because there is less surrounding pressure restricting them. When a launch occurs shortly before sunrise or after sunset, an additional visual effect becomes possible.
The observer on the ground may be standing in darkness while the rocket and its exhaust plume are already illuminated by sunlight at high altitude. The expanding gases scatter sunlight, creating an enormous glowing formation. The result can resemble a luminous jellyfish floating across the sky.
This phenomenon is sometimes called a space jellyfish. On October 13, 2026, a SpaceX Falcon 9 launched a Dragon spacecraft carrying supplies and scientific equipment to the International Space Station. The launch produced exactly this type of glowing exhaust plume, visible across portions of the eastern United States.
NASA documented the phenomenon and explained the role of sunlight illuminating the rocket’s exhaust. NASA The rocket was not crashing into a dome. The expanding exhaust was interacting with sunlight and the surrounding environment. The appearance may be unusual, but unusual does not mean inexplicable.
And there is an obvious question for anyone claiming these rockets are striking the firmament. If rockets cannot pass through the dome, how are satellites repeatedly placed into predictable orbits? Why do independently operated tracking systems consistently observe orbital objects? Why do launch vehicles follow trajectories that can be calculated and verified? And where is the physical evidence of these supposed collisions? A dramatic video is not enough to overturn centuries of independently reproducible observations.
When Faith Becomes a Defense of Misinformation
There is another issue here that deserves consideration. For some people, the flat-Earth debate has become more than a disagreement about geography. It has become a test of religious loyalty. They argue that accepting a spherical Earth means rejecting Scripture, trusting worldly institutions over God, or participating in a deception. But that creates a false choice.
Christians do not have to choose between believing in God and accepting observable scientific evidence.
Science investigates the physical processes of the natural world. Theology addresses questions about God, His relationship with creation, humanity’s purpose, and the meaning of existence. These disciplines can address overlapping questions, and their conclusions can sometimes create genuine interpretive challenges. But they are not automatically enemies.
Understanding atmospheric pressure does not require rejecting the Creator. Understanding gravity does not require denying divine authority. And recognizing that Earth is spherical does not diminish the significance of Genesis. Consider the words of Psalm 19:1 (NIV):
“The heavens declare the glory of God; the skies proclaim the work of his hands.”
Notice what David celebrates. The heavens themselves testify to God’s glory. He does not suggest that we must misunderstand the heavens to appreciate their Creator. If anything, discovering the extraordinary complexity of the universe should deepen our appreciation for creation.
The distances between stars, the mathematical precision of orbital mechanics, the properties of gravity, and the remarkable conditions that sustain life on Earth are extraordinary subjects worthy of exploration. For a believer, scientific discovery need not threaten faith. It can provide additional reasons to stand in awe of creation.
Question Everything, Including Your Own Conclusions
There is nothing inherently wrong with questioning established explanations. In fact, questioning is essential to learning. Scientific advancement frequently begins when someone challenges an existing assumption. But there is a difference between healthy skepticism and rejecting every piece of evidence that contradicts a preferred belief.
Healthy skepticism asks questions and evaluates the answers. Conspiratorial thinking can begin with a conclusion and then dismiss anything that challenges it as part of the conspiracy. If photographs from space demonstrate Earth’s curvature, the photographs must be fake. If satellites demonstrate orbital mechanics, the satellites must be imaginary. If thousands of independent scientists reach the same conclusions, they must all be participating in the deception. If a rocket produces an unusual exhaust plume, it must have struck the firmament.
At what point does a belief become impossible to challenge because every contrary observation is automatically dismissed? That is not an investigation. It is a conclusion protected from investigation. And Christians should be especially cautious about adopting that approach. Paul writes in 1 Thessalonians 5:21 (NIV):
“but test them all; hold on to what is good,”
Although Paul’s immediate context concerns evaluating spiritual claims, the underlying principle of careful discernment is worth remembering. We should not accept every claim simply because someone attaches a Bible verse to it. We should examine the evidence, consider the context, and remain willing to correct our understanding.
Faith does not require intellectual dishonesty, and discernment does not require abandoning reason.
When Being Right Becomes More Important Than Finding Truth
There is another psychological phenomenon worth considering in these discussions: cognitive dissonance. Cognitive dissonance occurs when a person experiences discomfort because new information conflicts with an existing belief, attitude, or behavior. Consider someone who has spent years insisting that Earth is flat and that the Bible teaches the existence of a solid dome above it.
They have watched countless videos, shared articles, argued with friends, and perhaps even questioned the faith of those who disagree. Their belief has become more than an opinion. It has become part of their identity. Now imagine presenting that person with compelling evidence that contradicts their position. Logically, we might expect them to reconsider.
But human beings are not always governed by logic. Instead of changing their conclusion, they may begin searching for ways to discredit the evidence. Photographs are fabricated. Scientists are lying. Governments are conspiring. Satellites do not exist. Rockets are striking an invisible barrier. Every contradiction becomes another reason to believe the conspiracy must be even greater than previously imagined.
This is where cognitive dissonance can interact with motivated reasoning and confirmation bias. Rather than objectively evaluating the evidence, people may selectively accept information that supports their existing beliefs while dismissing information that challenges them. And sometimes, the more deeply invested they become, the more difficult it is to acknowledge the possibility of being wrong.
Because admitting a mistake requires humility, while defending a mistake can feel like protecting one’s identity.
But this behavior is hardly limited to flat-Earth believers. We see it in politics, religion, personal relationships, professional decisions, and even our understanding of ourselves. People remain committed to failing decisions because they have already invested too much time or money. They defend unhealthy relationships because acknowledging the truth would require confronting years of misplaced trust. They refuse to apologize because admitting wrongdoing would damage the image they have constructed of themselves. And sometimes, they would rather continue defending something demonstrably false than endure the temporary discomfort of admitting they were mistaken.
Yet there is a profound irony in this behavior. The desire to appear right can become the very thing that prevents us from discovering what is right. Scripture repeatedly addresses the importance of humility and correction. Proverbs 12:15 (NIV) tells us:
“The way of fools seems right to them, but the wise listen to advice.”
And Proverbs 18:2 (NIV) states:
“Fools find no pleasure in understanding but delight in airing their own opinions.”
These passages are not invitations to ridicule people with whom we disagree. They are warnings that apply to every one of us. Including the person writing these words. The moment we become convinced that our understanding cannot possibly be mistaken is the moment we should become particularly careful about our assumptions.
Because intellectual humility does not require abandoning our convictions. It requires recognizing that our convictions should remain accountable to truth. There is nothing shameful about discovering that something we believed was incorrect. We learn. We grow. We adjust our understanding. That is how wisdom develops.
The greater danger is allowing pride to transform a correctable misunderstanding into a permanent commitment to error. Being wrong is part of being human. Refusing to consider that we might be wrong is what prevents us from growing.
And perhaps that is the most important lesson in the entire flat-Earth debate. The question is not simply whether we believe the Earth is flat or spherical. The deeper question is this: When confronted with evidence that challenges something we believe, are we more interested in discovering the truth or defending ourselves?
Because the answer reveals far more about our character than our understanding of astronomy.
God Does Not Need Us to Defend a Flat Earth
Perhaps the greatest concern I have with these arguments is the unnecessary conflict they create between Christianity and observable reality. When Christians insist that the Bible requires belief in a flat Earth enclosed beneath a physical dome, they create a theological obstacle that Scripture itself does not require us to create. They effectively tell people that accepting well-established scientific evidence means rejecting God. Why?
The Christian faith rests upon far more significant claims than the geometry of our planet. It concerns the existence and nature of God, humanity’s relationship with Him, the person and work of Jesus Christ, and the hope of redemption. None of those foundational teachings requires Earth to be flat. None requires rockets to crash into a solid barrier above the atmosphere. And none requires Christians to reject centuries of astronomical observation.
There is also an important matter of humility. Throughout history, Christians have disagreed about the interpretation of certain biblical passages. Recognizing that possibility does not mean Scripture is unreliable. It means human interpretation is not infallible. We should be willing to distinguish between what God has revealed and what we believe He meant. Those are not always identical.
The Greater Question
The flat-Earth and firmament debates reveal something about human nature that extends well beyond theology or astronomy. We have an extraordinary ability to find confirmation for things we already believe. Once we become emotionally invested in a conclusion, contradictory evidence can begin to feel threatening.
We stop asking whether our interpretation is correct and begin searching for reasons it cannot possibly be wrong. This happens in religion, politics, relationships, and virtually every other area of life. It is one of the reasons intellectual humility is so important.
Being willing to say I may have misunderstood something is not weakness. It is an essential part of learning. The universe is vast, complex, and filled with extraordinary phenomena. We have barely begun to understand everything about it. But acknowledging the limits of human knowledge does not mean abandoning the knowledge we have already established.
The Earth is not flat. There is no credible scientific evidence of a solid dome enclosing our planet. And glowing SpaceX exhaust plumes are not evidence of rockets crashing into the firmament. Christians can recognize these realities without surrendering their faith. In fact, we should be particularly committed to pursuing truth, even when that truth challenges our assumptions.
Because ultimately, if God is the author of creation, discovering how His creation actually works should never be something we fear.
The heavens declare the glory of God. We do not need to invent a dome to appreciate them.
