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?

Richard Dawkins and Lawrence Krauss discuss Something from Nothing

Richard Dawkins and Lawrence Krauss recently sat on the stage at the Australian National University to discuss "something from nothing." What follows are my notes from that conversation. (9) Dawkins offers two methods for illustrating the long periods of time that are critical to understanding natural selection. (13:30) The key idea is that we might be getting something from nothing. Life comes from non-life. Matter appears to come from the lack of matter. (14:47) We are dealing with the new version of "nothing." (16:00) It is plausible that everything started with no matter,and maybe no loss. It might not violate any laws for matter to come from the lack of matter. Especially in physics, scientists have learned to ignore the common sense. The total energy of the universe might be "zero." It might nonetheless be a bubbling brew of virtual particles, and this offends some people. (20) Krauss: The universe doesn't care what we like or what we understand. We need to deal with this. (21) Dawkins: Natural selection has equipped us to be bad physicists and we have to work to overcome this. (22) Space is curved, but we cannot visualize this. Our picture of natural/normal reality is myopic. [More . . . ]

The phrase that means “God faked the age of the Earth”

I've run into more than a few fundamentalist Christians who have insisted that the Earth is only 6,000 years old. "Then please explain the results of radiometric dating," I typically ask, adding that even carbon dating can accurately date materials up to 60,000 years old, far older than 6,000 years. Most modern savvy Young-Earthers won't fight me on the general usefulness or accuracy of carbon dating. Instead, they will insist that A) God has created an Earth that only looks like it is billions of years old, and B) I need to have faith. That is how they would explain everything older than 6,000 years old, including the Old Tjikko tree in Sweden, which certainly appears to be 9,550 years old. God must have transplanted it from another universe when he made this universe. The Young-Earthers thus offer an provocative argument. I don't believe it, but there's would be no way for me to disprove it.

Conservative Fantasy Role Playing

I wonder sometimes how a modern conservative maintains. Romney has won the New Hampshire primary.  All the buzz now is how he’s going to have a much tougher fight in South Carolina, primarily because of the religious and social conservatives who will see him as “not conservative enough.”  There is a consortium of social conservatives meeting this week in Texas to discuss ways to stop him, to elevate someone more to their liking to the nomination.  And right there I have to wonder at what it means anymore to be a conservative. I grew up, probably as many people my age did, thinking of conservatism as essentially penurious and a bit militaristic.  Stodgy, stuffy, proper.  But mainly pennypinching.  A tendency to not do something rather than go forward with something that might not be a sure thing. I suppose some of the social aspect was there, too, but in politics that didn’t seem important.  I came of age with an idea of fiscal conservatism as the primary trait. That doesn’t square with the recent past.  The current GOP—say since Ronny Reagan came to power—has been anything but fiscally conservative, although what they have spent money on has lent them an aura of responsible, hardnosed governance.   Mainly the military, but also subsidies for businesses.  But something has distorted them since 1981 and has turned them into bigger government spenders than the Democrats ever were.  (This is not open to dispute, at least not when broken down by administrations.  Republican presidents have overseen massive increases in the deficit as opposed to Democratic administrations that have as often overseen sizable decreases in the deficit, even to the point of balancing the federal budget.  You may interpret or spin this any way you like, but voting trends seem to support that the choices Republican presidents have made in this regard have been supported by Republican congressmen even after said presidents have left office.)

Robin Ince on the Magic of Science

I sometimes hear that science is a threat because it turns humans into "machines," and otherwise removes the magic of life.   I've sometimes had a fleeting thought of this type, for instance, while first encountering "Terror Management Theory" (I got over it). Does science ruin the magic of life? In this entertaining TED monologue, BBC radio show host Robin Ince argues more science teaches us about the astonishing behavior of the universe, the more we stand in awe. Understanding does not remove the wonder or the joy.  He offers many anecdotes and thought experiments.  For instance, one of the atoms that is now part of you was once part of Napoleon's knee;  "We are all totally recyclable."
