Summary of the Key Points
This article begins with the concept of “the cosmic origins of human elements” to reveal an underlying principle that spans both life and technology: whether it’s the human body, which has evolved over 3.8 billion years, or chips, which have developed in the past 70 years, both must continuously integrate elements from the periodic table to build systems of sufficient complexity. This is an inevitable choice dictated by the laws of physics. By examining the cosmic origins of the 60 elements that make up the human body, the crucial role of trace elements, and the similarities between the evolution of chips and the human body, the article illustrates that our bodies are a “concentrated version” of the 13.8 billion years of material evolution in the universe, and that technological development is following the same path as life’s evolution.
I. The Cosmic “Delivery List” of Human Elements: From the Big Bang to Neutron Star Collisions
Every element in your body is a “package” from different stages of the universe:
- The first batch (13.8 billion years ago): Hydrogen and helium from the Big Bang
Hydrogen accounts for 65% of human atoms, and each hydrogen atom is older than the solar system itself (13.8 billion years). Helium, though less abundant, is also a product of the early universe.
- The second batch (billion years ago): Carbon, oxygen, and nitrogen from the ashes of dead stars
These essential elements for life come from the cores of dying stars. Stars fuse hydrogen to form helium, which then transforms into carbon and oxygen. When these stars explode, their debris is scattered throughout space, becoming components such as calcium in your skeleton and phosphorus in your blood.
- The third batch (from supernova explosions): The violent birth of iron, zinc, and copper
Stars stop fusing at the element iron; heavier elements like iron, zinc, and copper are created through supernova explosions. When massive stars collapse and rebound, the high temperatures convert iron into these elements, which are later incorporated into your body through the food chain.
- The fourth batch (from neutron star collisions): The limited supply of iodine
The 20 milligrams of iodine in your thyroid gland come from the collision of two neutron stars at nearly the speed of light. This type of collision was first observed by humans in 2017; the resulting iodine traveled 130 million light-years before entering your body to regulate metabolism.
II. Trace Elements: Small in Quantity, but Critical for Life
Trace elements like zinc, cobalt, and selenium may seem insignificant, but their absence can be fatal:
- Zinc (2 grams): The “repairman” of DNA
Just half a fingernail’s weight of zinc is necessary to support more than 70 enzymes, including those involved in DNA replication and repair. Without it, the genetic information processing system would fail.
- Cobalt (1 milligram): The “king” of vitamin B12
Almost all cobalt is found in the core of vitamin B12. A deficiency can lead to irreversible nerve damage as the protective layers around nerve fibers are destroyed.
- Selenium (15 milligrams): The “firefighter” of cells
Only 55 micrograms per day are needed, but excess can be toxic. Selenium helps remove harmful waste products from cellular metabolism; without it, cells would be damaged by their own waste.
- Molybdenum (0.3 milligrams): The “detoxifier” of sulfites
A lifetime’s supply is just 0.3 milligrams, and it converts sulfites in food into harmless substances. Without it, newborns would die within weeks. This amount of molybdenum comes from three cosmic events: the death of low-mass stars, supernovae, and neutron star collisions.
III. The Hidden Abilities of Common Elements: More Than Just “Boosting Blood and Bones”
Elements like iron, calcium, sodium, and potassium have more roles than you might think:
- Iron: Not only does it transport oxygen, but it also acts as a “power station worker.”
Iron in hemoglobin not only binds oxygen but can also switch between charged states, allowing it to pick up and release oxygen in the lungs and muscles. It also participates in energy production and antioxidant processes.
- Calcium: Only 1% of calcium is free and active; the remaining 99% is in bones as a building material. The remaining 1% regulates muscle contractions and nerve signals. Every blink and finger movement depends on calcium’s regulation of these processes.
- Sodium and potassium: They maintain the electrical potential difference across cell membranes, acting like “small batteries.” When neurons are activated, they rapidly charge and discharge, which is the physical basis of thinking and blinking (20%-40% of the brain’s energy is used for this).
- Magnesium: It is essential for the production of ATP, the cellular energy currency. Without magnesium, all energy transactions in the body would be impossible. Magnesium is also a core component of chlorophyll in plants; eating leafy greens provides this essential nutrient.
IV. Why Can’t Life Simplify Its Composition? Physical Laws Dictate Otherwise
The creator didn’t cut corners; physical laws prevent simplification:
- Early life emerged from “metallic soups”
3.8 billion years ago, minerals like iron, nickel, and zinc concentrated in deep-sea hot springs, which were used by early forms of life as tools. The reaction centers in modern cells are essentially the same as those found in these hot springs.
- The irreplaceability of metal ions
Chemical reactions involving carbon and hydrogen are too slow and imprecise, while metal ions can easily switch between charged states, catalyzing reactions with very low energy requirements (lab temperatures of several hundred degrees are needed, but the human body functions at 37 degrees Celsius). This was a critical factor in the evolutionary arms race.
- Evolution has “fixed” the composition
Once life incorporated metal elements into its systems, it couldn’t change them. For example, the iron-sulfur clusters in mitochondria still use the same mineral compositions as those from 3.8 billion years ago. Simplifying these systems would be fatal.
V. The Similar Path of Element Integration in Humans and Chips
The evolutionary processes in humans and chips follow similar patterns:
- Chips evolving from a single element (silicon) to using most of the periodic table
Early chips used only silicon or germanium, but modern advanced processes involve dozens of elements such as silicon, hafnium, cobalt, and ruthenium. To improve performance, scientists choose the most suitable elements from the periodic table.
- A necessary pursuit of limits
No single element is perfect; to enhance performance, we must use the most suitable combinations. Life has integrated 60 elements over 3.8 billion years, and chips are approaching this level in just 70 years. This is not a coincidence but the inevitable path for developing “precision systems.”
Conclusion: You Are a Concentrated Version of 13.8 Billion Years of Cosmic Evolution
Your body contains traces of events from the distant past: iodine from neutron star collisions, calcium and sodium/potassium from ancient hot springs, and zinc from supernovae that repair DNA. The universe spent 13.8 billion years gathering all the best “tools” to create you—a complex system capable of drinking coffee, sending messages via WhatsApp, and worrying about hairline thinning. This is not a coincidence but the result of physical laws governing complexity. Whether it’s carbon-based life or silicon-based chips, we must accept these constraints imposed by the laws of physics.
