Carbon-14 Itself Argues for an Old Earth

I was reading The Cosmic Story of Carbon-14 and had a thought involving the Abundance of the Elements and isotopes. We now know how the elements formed, and have measured their relative abundances for a while and across the universe. The theory of how they form matches every measurement. Basically, Hydrogen and traces of Helium have been around for over a dozen billion years. Heavier elements form when the mass attraction of enough hydrogen squishes a star's core to fuse together helium and some lithium, a star is born. All the rest form from the extreme compression and sudden release of supernovas. All that hydrogen and helium (basically protons and neutrons as there are no attached electrons at those pressures) are squeezed to dissolve into a quark soup then expanded and quick-frozen before they can push themselves apart. What is expected from this is an asymptotic curve of element abundances with hydrogen at the high end, and slight peaks forming at iron, xenon, and lead (particularly stable elements). This is what is measured in our solar system: Don't let the zig-zag pattern confuse you. Odd numbered elements are harder to hold together than even ones; each pair of protons needs a pair of neutrons to let them stick together. But odd numbered ones have that odd pair of singles; they are just less likely to form. But how does Carbon-14 fit in? What really freezes out from the splash of quark soup is not so much elements as isotopes. Every possible isotope forms in its proportional place along the curve. Then the unstable ones follow a decay chain until either they reach a stable element, or we measure them somewhere along the way. Uranium, for example, has 3 isotopes that last long enough to have hung around the 5 billion years or so for us to measure them. Technetium, on the other hand, is only found today as a decay byproduct from other elements. So back to carbon. The three most common isotopes of carbon weigh 12, 13, and 14 atomic units (aka fermion masses: neutrons or protons). C-12 is most of it, C-13 is 1.1%, and C-14 is about 1/1,000,000,000,000 part of it. Carbon 13 is an odd-numbered isotope, and therefore intrinsically rare. Carbon-14 has a half life of 5,730 years. So if it were created in the expected normal proportion to carbon-12 billions of years ago, we would expect to not see any left. Where it all comes from is recent nuclear collisions between protons (cosmic rays) and nitrogen in the upper atmosphere. (More details here). We see the amount of carbon-14 that we'd expect for a regular continuous influx of cosmic rays that we do measure. But if all the elements had been made 10,000 years ago, we'd expect about C-14 to be about 1/4 of the total carbon, not the mere 1/1012 of it that we know is produced by cosmic ray collisions. It turns out that comparing the abundance of isotopes of any element indicates the age of the planet to be between 4,000,000,000 and 5,000,000,000 years. But what (I can predict this argument) if God created the elements with the isotope distributions intentionally skewed to just look like everything is that old? The old God-is-a-liar and created the young world old to eventually test faith of careful observers argument. I counter this with:

Given God and the Devil, which one has the power to put consistent evidence in every crevice of this and other planets and throughout the universe for every method of observation in every discipline for all interested observers of any faith, and which one might inspire a few men men to write and edit a book and spread its message eagerly that can be interpreted to contradict that massive universe of evidence?

Is your original cell still alive?

I'm in the process of watching a (Great Courses) video course titled "Understanding DNA, Genes and their Real-World Applications," taught by Professor David Sadava. In today's lecture (#5) he asked whether one's original cell still exists in each adult. Each of us came from one cell, a fertilized egg, which divided, then divided again, on and on. Sadava's question was whether our original cells might still be alive somewhere in our adult human bodies, decades later. His answer was that there is no compelling reason to assume that that original cell is not still "somewhere" inside of you, one cell among the 60 trillion cells that make up your body. Intriguing thought.

Explaining the punctuation of equilibrium

The April, 2010 edition of Discover Magazine profiles biologist Lynne Margulis, famous for her well accepted suggestion that eukaryotic bacteria did not evolve in linear fashion, solely as as a result of natural selection. Rather,

mitochondria and plastids--vital structures within animal and plant cells--evolved from bacteria hundreds of millions of years ago, after bacterial cells started to collect and interactive communities and live symbiotically with one another. The resulting mergers yielded the compound cells known as eukaryotes, which in turn gave rise to all the rest-the protoctists, fungi, plants and animals, including humans.
There was a shocking idea at the time (1967), but, as described in this article by Dick Teresi, the more recent ideas of Margulis are even more controversial. The Discover Magazine article documents her arguments that symbiosis is "the central force behind the evolution of new species." This position runs counter to the holding of modern conventional scientific wisdom, that new species arise through "gradual accumulation of random mutations, which are either favored or weeded out by natural selection." Margulis holds that random mutation and natural selection play a minor role and that the big leaps in the evolutionary record "result from mergers between different kinds of organisms, what she calls symbiogenesis." The Discover article takes the form of an interview, in which the dominant theme is that "natural selection eliminates and maybe maintains, but it doesn't create." Margulis argues that the laws of genetics "show stasis, not change." She was prompted by the fact that there is no record of major fossil change until 542 million years ago, yet all of a sudden we see the Cambrian explosion. Stephen Jay Gould coined this phrase, "punctuated equilibrium," "to describe a discontinuity in the appearance of new species." According to Margulis, her explanation of symbiogenesis explains these discontinuities and should thus be considered the primary mechanism for evolution. Margulis carefully distinguishes her approach from arguments based on "intelligent design." She holds that those who advocate for "intelligent design" have nothing meaningful to offer to the scientific conversation. [More . . . ]

Twins appear to share thoughts through thalamic bridge

Two extraordinarily unusual five-year old twins share more than conjoined skulls.  They appear to share some of their thoughts.  Susan Dominus of the New York Time covers this emotionally and scientifically rich story well from many angles.

Their brain images reveal what looks like an attenuated line stretching between the two organs, a piece of anatomy their neurosurgeon, Douglas Cochrane of British Columbia Children’s Hospital, has called a thalamic bridge, because he believes it links the thalamus of one girl to the thalamus of her sister. The thalamus is a kind of switchboard, a two-lobed organ that filters most sensory input and has long been thought to be essential in the neural loops that create consciousness. Because the thalamus functions as a relay station, the girls’ doctors believe it is entirely possible that the sensory input that one girl receives could somehow cross that bridge into the brain of the other. One girl drinks, another girl feels it.

Creating Doubt in Science

There is currently a strong suite of Discovery Institute bills running through state legislatures to allow "alternative theories" to be taught in science classes. See list here: Antievolution Legislation Scorecard. There is not a direct link back to the Discovery Institute, but it is their wording, seen before and passed in places like Texas and Louisiana and Tennessee. From a legal standpoint, the bills look harmless, closely resembling intellectual freedom policies. But the point is clearly to sow confusion about the difference between science and just making things up, especially in regard to evolution and climate science. Hemant Mehta suggests that it would only be fair to show this video in churches where the churches put their books into science classes.
