La proporción áurea en el ADN, las galaxias y la arquitectura
Golden Ratio in DNA, Galaxies, and Architecture is a captivating, persistent idea. It suggests a universal blueprint for beauty and life.

This number, $\phi$ ($1.618…$), seems to appear everywhere. We see it in art, nature, and the deep cosmos.
Or do we? This column explores the thin, fascinating line between mathematical truth and human mythology.
We must investigate the claims of this “divine proportion.” We must also separate verifiable science from human pareidolia. Is this ratio a true cosmic code? Or is it just a beautiful, compelling coincidence?
What Exactly is the Golden Ratio?
This famous number, known as $\phi$ (phi), is mathematically unique.

It is an irrational number, approximately $1.6180339…$ Ancient Greeks, including Euclid, first defined its geometric properties. You find it by dividing a line into two unequal parts.
The entire line (A+B) divided by the longer part (A) must equal the longer part (A) divided by the shorter part (B).
This creates the equation (A+B)/A = A/B = $\phi$. This ratio is also intrinsically linked to the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13…). As you divide successive numbers (e.g., $13/8$), the result approaches $\phi$.
This profound mathematical elegance has inspired mystics for centuries. It feels like a fundamental building block of reality.
Why Does This Number Fascinate Us So Deeply?
Humans are hardwired to find meaningful patterns in chaos. The golden ratio appears to offer a universal, objective standard for beauty and harmony. We are psychologically drawn to balance and coherent proportion.
An 1876 study by German psychologist Gustav Fechner suggested this preference. He found that people tended to prefer rectangles closest to the “golden” shape.
This idea of an ‘ideal’ form is aesthetically powerful. It provides a bridge between abstract math and tangible beauty.

Is This Preference Real or Imagined?
Does this preference actually hold up to modern scrutiny in 2025? Recent studies, like those from UC Berkeley’s Haas School, are far less conclusive. They found that preferences vary widely based on cultural context.
The fascination with the Golden Ratio in DNA, Galaxies, and Architecture may say more about us than it does about the universe.
It is a form of mathematical confirmation bias. We seek the pattern, so we find it everywhere, even when it isn’t a precise fit.

The Analogy of the Clouds
This human tendency to see patterns is called pareidolia. It is the same psychological impulse that makes us see a face in the clouds or a man in the moon. We are programmed to find faces, so we see them.
We are fascinated by $\phi$, so we seek it out. If you draw enough lines on any complex object a building, a face, a galaxy you will eventually find ratios that approximate $1.618$.
This does not imply a divine blueprint; it only proves that complex systems contain complex mathematics.

How Does the Golden Ratio in DNA, Galaxies, and Architecture Hold Up to Scrutiny?
This is where the grand, romantic theory meets the hard, measurable reality of science. The claims are broad and sweeping, but the verifiable evidence is often thin or nonexistent.
We must apply rigorous, journalistic skepticism to these popular ideas. Let’s break down the three most famous examples one by one.
Does the Golden Ratio Appear in Ancient Architecture?
This is the most famous claim, citing the Parthenon in Athens. It is alleged that the temple’s façade fits perfectly within a golden rectangle. This is the “classic” example proponents use to prove ancient wisdom.
However, verifiable measurements do not support this claim. A detailed 2015 analysis by $\phi$ researcher George Meisner confirms the Parthenon’s dimensions do not closely align with $\phi$.
Many lines must be drawn arbitrarily on photographs to “force” the fit. There is zero historical evidence the Greeks (like Phidias) even knew of, let alone used, $\phi$.
What About Modern Architects Like Le Corbusier?
Here, the evidence is undeniable, as it was intentional. The 20th-century architect Le Corbusier explicitly used the golden ratio. He developed a detailed system called “Le Modulor” in the 1940s.
His Unité d’Habitation in Marseille, France, is a clear case. Its facade, panels, and internal layouts all use Modulor proportions.
Le Corbusier believed this created “harmonious” human-centric spaces. So, $\phi$ exists in architecture, but usually only when deliberately put there by the designer.
Is the Golden Ratio Found in Spiral Galaxies?
This claim centers on the stunning beauty of spiral galaxies. Many, like M51 (the Whirlpool Galaxy), appear to be perfect golden spirals. A golden spiral has a specific, constant pitch angle of $\approx 17.03$ degrees.
The problem is that real galaxies do not conform to this. Spiral galaxies are indeed logarithmic spirals, a broader category.
But their specific pitch angles vary widely, from 10 to 40 degrees. Very few, if any, precisely match the golden spiral.
The claim that the Golden Ratio in DNA, Galaxies, and Architecture applies to the cosmos is a classic case of aesthetic approximation, not astrophysics.
Is the Golden Ratio Truly in Our DNA?
This is perhaps the most compelling and scientifically debated claim. The argument focuses on the DNA double helix structure.
When viewed from the top, the helix cross-section (a decagon) is intrinsically based on $\phi$ geometry.
Furthermore, the dimensions of the helix are cited as proof. One full cycle of the helix measures 34 angstroms long.
The width of the helix is approximately 21 angstroms. These two numbers (21, 34) are sequential in the Fibonacci sequence. Their ratio ($34/21 \approx 1.619$) is a remarkably close approximation of $\phi$.
This numerical link is startling and scientifically noted. Researchers like Jean-Claude Perez have published papers on this very topic.
They argue this $\phi$-based structure provides maximum efficiency and stability for DNA. The Golden Ratio in DNA, Galaxies, and Architecture finds its strongest, most plausible footing right here.
But is it fundamental physics or a profound coincidence? Many mainstream biologists remain skeptical, labeling it numerology.
They correctly argue the angstrom values are averages, not rigid constants. This remains a truly “uncommon discovery,” existing on the fringe of scientific consensus. It is a tantalizing clue that is not yet fully proven.
What is the Real Science vs. the Myth? (The Great Decoupling)
We must decouple real mathematics from its mystical application.
La idea de la Golden Ratio in DNA, Galaxies, and Architecture is an idea that is often more romantic than it is universally true. It is a seductive story that we want to be real.
The universe is beautiful without needing one “magic number” to govern it all. The real science of biology, cosmology, and physics is far more complex and subtle.
It is not governed by a single aesthetic ratio, but by a symphony of interlocking laws.
| Claimed Domain | The Popular Claim | The Scientific Consensus (2025) |
| Ancient Architecture | The Parthenon and Pyramids were built using $\phi$. | Debunked. Measurements do not align. A myth started in the 1800s. |
| Modern Architecture | Le Corbusier used $\phi$ in his designs. | Fact. He explicitly used it in his Modulor sistema. |
| Spiral Galaxies | Galaxy spirals match the Golden Spiral. | Mostly False. Galaxies are logarithmic spirals, but with varying angles. |
| Human DNA | The double helix ($34\r{A} \times 21\r{A}$) matches $\phi$. | Debated. The ratio is remarkably close, but causality is unproven. |

Why We Must Remain Skeptical
As a journalist, I must prioritize verifiable evidence over aesthetic preference. The idea of a secret code woven into reality is compelling, but it can lead us away from rigorous science and toward simple mysticism.
El Golden Ratio in DNA, Galaxies, and Architecture is a seductive story.
But often, it is just that: a story. We must be careful not to impose our human sense of beauty onto the fundamental, and often non-intuitive, laws of the cosmos.
Fascinating Example
The human hand. It is often claimed that the phalanges (bone segments) in our fingers are proportioned according to the golden ratio. This claim is easily testable. Just measure your own hand.
You will find the ratios vary dramatically from person to person. They rarely, if ever, precisely average to $1.618$.
This is the perfect metaphor for the entire myth: it looks plausible from a distance, but it fails under close, critical inspection. It is an ideal imposed upon a varied, imperfect reality.
Conclusion: The Universe’s Complex Symphony
The search for the Golden Ratio in DNA, Galaxies, and Architecture is ultimately a deeply human one.
It reflects our profound desire for universal order and a connection between our consciousness and the cosmos. We want the universe to share our sense of beauty.
The evidence, however, reveals a more complex and nuanced truth. The ratio is present in architecture when designers intentionally place it there.
Its presence in galaxies is a beautiful case of mistaken identity. Its appearance in DNA remains the most compelling, yet debated, clue.
The golden ratio is a mathematical marvel, but it is not the single, universal blueprint for all reality. The universe operates on a symphony of laws, not just a single, perfect note.

Preguntas frecuentes
What is the difference between the Golden Ratio and the Rule of Thirds?
The Rule of Thirds is a compositional guideline in photography. It divides a frame into nine equal squares, suggesting placing subjects at the intersections.
It is a simplified approximation of the golden ratio, but it is not mathematically the same.
Did ancient artists like Leonardo da Vinci use the Golden Ratio?
This is heavily debated, much like the Parthenon. Da Vinci deeply studied human proportion (see Vitruvian Man).
However, there is no direct proof that he consciously applied $\phi$ to the Mona Lisa. These claims were mostly applied retroactively, centuries after his death.
Is the Golden Ratio related to the Fibonacci Sequence?
Yes, they are intrinsically linked. As you divide successive numbers in the Fibonacci sequence (e.g., 5/3, 8/5, 13/8, 21/13…), the resulting number gets closer and closer to $1.618…$ ($\phi$).
Why do some scientists still investigate the Golden Ratio in DNA, Galaxies, and Architecture?
Because the link between mathematics and the physical world is real and profound. While many claims are false, the DNA connection remains tantalizing.
Science must investigate anomalies, even if they seem mystical. The goal is to find true physical principles, not just coincidence.
