Six Elements and Three Interactions

Six Elements and Three Interactions

You can find six elements in the cells of all living things: carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. Without all of those elements, life, as we know it, could not exist. Living things require many other elements to perform various functions to survive, but those six elements are the building blocks of living cells. Life depends on those six elements and three interactions.

What do those elements have in common? For one thing, they are all non-metals. More important is that those six elements have stable atoms that are not radioactive. Radioactive decay of the atoms of some elements releases alpha or beta particles, which are destructive to living tissue. When those particles enter living tissue, they cause the release of high-energy particles in the cells. That destroys DNA, causing disease and mutations.

We are exposed to some radiation every day, but the amount is usually small, and our cells have a remarkable ability to repair themselves. If any of the six elements released radiation particles, life could not exist. Why are these six elements so stable? We have to consider the six elements and three interactions.

Three carefully balanced forces or interactions work within every atom to give stability. They are the strong force, the weak force, and the electromagnetic force. The strong force binds protons together in the atomic nucleus. The weak force is responsible for radioactive decay. Electromagnetic interaction between the protons in the nucleus and the electrons holds those electrons in the atomic shell while allowing chemical interactions between elements.

The key to stability is the precise balance between the three forces. A change in the value of any of the three would upset the balance, making our atoms unstable and life impossible. Was it mere luck that caused the delicate balance of those forces? Is it possible that the balance and our existence are just chance accidents? We think a better explanation is that the Creator of the universe carefully designed the six elements and three interactions.

CLEVER Planets

CLEVER Planets Include Earth
We have often mentioned many of the conditions that must exist to make a planet habitable. The number is large and growing as science learns more about Earth’s special life-supporting features. Now NASA has awarded $7,700,000 to Rice University to conduct a five-year study to see what it takes to create a “recipe for a habitable planet.” The project has been named CLEVER Planets, an acronym for Cycles of Life-Essential Volatile Elements in Rocky Planets.

The award comes from NASA’s Nexus for Exoplanet System Science (NexSS). The research team will include experts in astrophysics, atmosphere and climate science, geology, geochemistry, geophysics, and organic chemistry. The investigators are from Rice University, NASA’s Johnson Space Center, the University of California-Davis, UCLA, and the University of Colorado-Boulder. This will be the most in-depth study of what it takes to create a habitable planet.

The lead investigator of CLEVER Planets, Rajdeep Dasgupta of Rice, wrote: “A recipe for life as we know it requires essential elements like carbon, oxygen, nitrogen, hydrogen, phosphorus, and sulfur.” Of course, that is not all that is required to create a recipe for a life-supporting planet. There are also many other conditions including liquid water, the right temperature with stable conditions, a proper atmosphere, and shielding from dangerous radiation. Having an atmosphere requires a planet of the right size to have the right amount of gravity to sustain an atmosphere. To have liquid water and the right temperature requires that the planet must be the right distance from the right kind and size of star. The planet needs a magnetic field to shield from dangerous particles coming from the star. To have a magnetic field, there must be magnetic elements inside the planet. The list goes on and on.

We look forward to seeing the results of the CLEVER Planets study five years from now. The bottom line is that it is very, very difficult to get all of the right ingredients required to create the recipe for a habitable planet. Earth is an exceptional place in the universe.

It seems doubtful that we will find any other planet similar to Earth. But as we have said before, if there is any form of life anywhere else in the universe, that has nothing to do with the existence of God. We believe in a God who can do anything He chooses to do in keeping with His nature.
