Rutgers scientists: Asteroids did kill the dinosaurs

(PhysOrg.com) -- Sometimes, you just cant trust the iridium. A silvery-white natural metal thats a member of the platinum family, iridium is a key ingredient in the manufacture of spark plugs. Iridium is also an important piece of evidence in a mystery that scientists have debated for decades why did dinosaurs disappear from the face of the earth?
The prevailing scientific consensus is that at least one asteroid possibly more hit the earth about 65 million years ago, showering the planet with dust and debris, blocking sunlight, causing firestorms, and marking the end of the Cretaceous Period and the beginning of the Paleogene Period. Most scientists believe the impact was directly responsible for the mass extinction of many species of plants and animals most famously, the dinosaurs.
The impact also left a clue a chemical signature in the earths crust called the iridium anomaly. Iridium is rare in the earths crust but far more abundant in asteroids. Thats why, all over the world, scientists find unusually high concentrations of iridium in sediment layers at the boundary between the Cretaceous and Paleogene periods called the K-Pg Boundary by geologists.
All over the world, that is, except in Freehold, New Jersey 25 miles down the highway from Rutgers Universitys New Brunswick Campus.
In several cores drilled at sites around New Jersey much of which was covered by the ocean when dinosaurs roamed the earth fossilized sea creatures are found below the K-Pg Boundary, buried by debris that contains iridium. This evidence supports the iridium anomaly and the consensus that asteroids killed the dinosaurs..
But not in Freehold. In 2007, scientists Neil H. Landman, of the American Museum of Natural History, and Ralph O. Johnson found fossils above the iridium-laden boundary in Freeholds Tigh Park. Johnston is a self-educated paleontologist from West Long Branch, N.J.
Some scientists argue that the work of Landman and Johnson casts doubt on the asteroid consensus. These scientists say the Freehold evidence suggests dinosaur extinction was caused by catastrophic volcanic eruptions.
Enter Rutgers geologist Ken Miller, a professor of earth and planetary science in the School of Arts and Sciences. According to a paper authored by Miller, Rob Sherrell, Paul Field. and their colleagues in the journal Geology, the real explanation for the Freehold findings is far more simple: The iridium moved.
And how do they know that? Sherrell and Field, of the Institute of Marine and Coastal Sciences in the School of Environmental and Biological Sciences, went through a highly specialized, painstaking process of geochemical analysis to pinpoint the location of the K-Pg barrier at another Freehold site near the one excavated by Landman and Johnson..
Sherrell and Field analyzed sediment samples from the layers near and within the K-Pg boundary, using a method called nickel-sulfide fire assay to do the job. They melted the sediment at a high temperature, forming a bead of nickel sulfide. The iridium migrated to the bead, and the bead itself was in a crucible of sediment glass formed by the melting. They broke that glass to get to the bead, and then dissolved the bead in acid. The nickel dissolved and the iridium was left behind as very fine particles in the acid. They filtered the solution, and then dissolved those tiny particles in a second acid solution. This process produced a purified iridium solution that Field and Sherrell analyzed in their mass spectrometer.
We infer that, at the Freehold site, the iridium has migrated, Sherrell said. Just what caused the iridium to migrate below the layer of fossils isnt clear.
Miller, the geologist, speculates that the sediment is sandier at the site in Freehold than at other sites in New Jersey, and this may have allowed what he calls percolation to occur. But the bottom line is clear: The iridium moved.

The theories of science are more useful models for developing technology than religious doctrine is. However, scientific theories have gaping holes that require as much faith as religious doctrine to rationalize.
The gaping hole is that the observations we are making now can be reliably wound backward all the way to some event for which no evidence can be obtained at this time. While observations clearly demonstrate systems that have evolved over time, there is no way to prove at this time that they weren't created in a state of complexity and evolved from there.
Occam's razor may conclude that the extrapolation all the way to the singularity may be the simplest explanation, but the universe is not bound by Occam's razor. In addition, extrapolation is a mathematical no-no.
My point is that you cannot claim the moral high ground based your belief that scientific theories are correct any more than a religious zealot can.

Moral Highground may have been a poor choice of words, but I was character limited. I meant to convey the issue in terms of correct/incorrect where one person believes their view to be correct and other views are incorrect. Nobody is in a position to claim they are correct and, in my view, nobody ever will be.
I do believe in God and I do believe the unverse was created. However, I don't see the Bible as literal truth or some kind of sequence of events. I see it as a moral guide that lists the rules by which I am required to live.
I will use the theoretical model that works the best on whatever the task at hand is. If I am doing my job as an engineer, then the laws of physics are the best model to use for that work and the Bible is useless. If I have a moral problem to solve, then the Bible is the best model for me to use for that work and the laws of physics are useless.

Even if models reach the point that they can accurately describe the condition of the universe if it were compressed down to a single point, that does not constitute proof that the initial condition of the universe was a single point. It merely demonstrates what could happen if we were able to create that condition.
I do not know the initial conditions. I belive they are fundamentally unknowable because our evidence can never be more than circumstantial. Science is claiming the singularity as the initial condition, so the burden of proof is on science, not me. The proof being offered in terms of CMBR is consistent with BB, but it is also consistent with M-Theory. The evidence is circumstantial, not conclusive.

This is akin to me saying Greek mythology had a correct statement of abiogenesis because man was created through lightning striking a mud puddle.
I wouldn't say that, because it's utter horseshit without some serious mental gymnastics.
Secondly, Genesis states that the star were created after the earth (wrong order and impossible) and that man and beasts existed before there was a sun and moon(also impossible).

Neither conclusive NOR circumstantial. It is solid evidence that the Universe was, at the very least, much smaller and just hot gas a little over 13GY ago.
I feel the need to ask this question. Do you believe in the Flood? If so where is the evidence? If not why believe the rest of the supernatural stuff?This reminds of pair of lines in The Princess Bride. I also think you have an odd idea of physics if you think anything is conclusively proved. Maybe Newton thought that way but its rare these days.

I never said that renormalization was extrapolation, I used it as an example of physicists skirting mathematical rules when they are inconvenient. I also said that I had no issue with it as a practical tool, I object to its use as part of the mathematical framework of a theory. Both Dirac and Feynman objected to renormalization. Dirac objected on mathematical grounds, Feynman objected to the lack of consistency.
As an engineer, of course I use extrapolations and approximations in my work. I just don't claim that they represent some fundamental truth.

It is not a matter for debate as there is no absolute best moral guide. My basic point was that all models have limited applicability so you choose the model you believe to be the best fit for a problem. My examples were intended to illustrate that point. If you think that is wrong, then that is your opinion.

I doubt that they are merely fortuitous. It is likely they evolved since they seem to have survival value. Emotional reward for successful behavior reinforces such behavior. Emotional punishment for being a putz tends to discourage such behavior. Which really should enhance survival. Since humans, me included, sometimes engage in petty revenge it is counter to survival to go around pissing off your neighbors.
Unless you are annoying your neighbors in a Socratic sort way in an attempt to improve their chances of survival. Which means that people should have evolved a tendency to occasionally intentionally piss off their neighbors.

Tribal members interacted with each other and with competing tribes. The individuals that prevailed were able to communicate and cooperate most effectively in a tribal environment. This gave their tribes a decided advantage in competition with other tribes.
Society has since found ways of expanding this intertribal behavior over larger socially-connected groups.

It is pretty much something that cannot not happen. There are mutations. Probably all of us have one or more recent mutations. There is an environment that is pretty merciless about killing off anything that doesn't fit well enough. It is clear that any change(mutation) that would enhance survival or rate of reproduction would something that the environment kills of less slowly than those without those mutations. This is the cause of evolution and unless you or someone can show that there is no environmental or no mutations then I have to consider quite well proved.

A scientist using the proper instruments and apparatus is already interpreting his observations. He is anticipating objective relationships between subjective perceptions. Instrumentation and apparatus are merely means for guiding subjective observation, so that a measurement can be obtained by comparing different observations. All measurement is only a comparison between at least two observations. Measurement itself requires a community of observations, which implies a community of observers.

"Pylyshyn (1999) has argued that while these properties tend to occur with modules, one stands out as being the real signature of a module; that is the encapsulation of the processes inside the module from both cognitive influence and from cognitive access. This is referred to as the "cognitive impenetrability" of the module."
"Other perspectives on modularity come from evolutionary psychology, particularly from the work of Leda Cosmides and John Tooby. This perspective suggests that modules are units of mental processing that evolved in response to selection pressures. On this view, much modern human psychological activity is rooted in adaptations that occurred earlier in human evolution, when natural selection was forming the modern human species."

3) Axioms of logic are not dependent on any state of the universe. These three statements are inconsistent with one another. Since 2 and 3 are obviously true, 1 must be false. QED

"Some proponents of emergentist or generative philosophy, cognitive sciences and evolutionary psychology, argue that free will does not exist. They suggest instead that an illusion of free will is experienced due to the generation of infinite behaviour from the interaction of finite-deterministic set of rules and parameters. Thus the unpredictability of the emerging behaviour from deterministic processes leads to a perception of free will, even though free will as an ontological entity does not exist. Certain experiments looking at the Neuroscience of free will can be said to support this possibility."

C is only true if B is not.
If the Universe is in the state of Timelike Infinity then logic of any kind will be impossible. Which makes logic dependent on the state of the Universe. Timelike Infinity is when the expansion of the Universe has all the particles so far apart that they no longer interact.
A is falsified by experiment in any case.
Whether you like my idea or not B and C can only both be true if I am right and you are wrong. Your way has logic running on the Universe thus making it dependent on the Universe.

Proposition B states that the Axioms of Logic are part of the Universe. What does this mean? Simply that the laws of logic make a difference in the evolution of the universe from time t0 to time t1. I am a part of the universe in the same way, if we were to pluck me out of existence, it would change what happens next.
I'm not sure what you're point is with your argument about the universe at the end of time. Doing logic is impossible in such a state, but the laws of logic are still true in that universe. Nobody has to do logic for it to be valid. Logic does depend on the existence of the universe because every axiom of logic begins with the supposition of existence (given any x, there exists some y, etc.). However, logic doesn't depend on any state of the universe.

"I am not an atheist,"he began. "The problem involved is too vast for our limited minds. We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written those books. It does not know how. It does not understand the languages in which they are written. The child dimly suspects a mysterious order in the arrangement of the books but doesn’t know what it is. That, it seems to me, is the attitude of even the most intelligent human being toward God. We see the universe marvelously arranged and obeying certain laws but only dimly understand these laws."

One important note- when scientists use the term 'universe' it is usually referring to something within a particular theory that they have described much more succinctly using mathematics. The word is an approximate representation of an exact component of their theories which can't be described adequately with words.
Philos will try to describe the same thing using words alone, but since they usually have no appreciation of the maths then they will always fall short of an adequate or useful description, which is absolutely necessary in discovering anything more about it, or conveying information about it to others.
To scientists words are only a convenience. They know they are worth little for explaining, clarifying, or predicting. What you are trying to say can only be said with numbers, not words.

"I am not an atheist..."
Not sure why you brought this up, but.....
In 1954 Einstein also wrote: "the word 'God' is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honourable but still primitive legends which are nevertheless pretty childish."
"For me, the Jewish religion like all other religions is an incarnation of the most childish superstitions"
"the Jewish people to whom I gladly belong, and with whose mentality I have a deep affinity, have no different quality for me than all other people."
"As far as my experience goes, they are also no better than other human groups, although they are protected from the worst cancers by a lack of power. Otherwise, I cannot see anything 'chosen' about them."

I think what we're getting hung up on here is what the source of determination is. The laws of causality and the laws of nature (being a bit repetitive there), are usually what's thought to completely determine something's existence. That's the only reason I can think that you're getting so hung up on other universes, that because they have other laws, they would be determined differently.
But that's not relevant to this argument. It doesn't matter what the mechanism of determination is. The first premise just says that there's some mechanism of determination for everything. It doesn't require mechanisms to be the same in a single universe, let alone across universes.

Your 'isms' all come up short. None ever explained anything as we now know. Science has taken over the function of defining human behavior and perception, because it now has the ability to do so.

You are mistaking UNIVERSAL for UNIVERSE. One is a logical term and the other is an astronomical term. It has been that way for a long time. The laws of universe A can be different from Universe B.Only on a per universe basis.I think its your logic that is the hangup.No. That is why I am trying to be clear on there being a strong possibility that there are OTHER Universes.

The next shows why you are fighting against logic transcending universesOnly within a given UniverseWhich transcend any universe. Indeed we have already agreed that both Euclidean and Non-Euclidean logic are valid even if one is not relevant to this Universe.

Look, either logic transcends physical reality or it is dependent on physical reality. You can't have both.

At least I now know what you thought you proved. You made a hidden assumption that contradicted one of your givens.
Your given
Which makes them OUTSIDE the Universe.
Hidden assumptions are often hard to see. It took millennia for anyone to spot the hidden assumptions in Euclid's original geometry. They have been patched.

"Most philosophers consider logical positivism to be, as John Passmore expressed it, "dead, or as dead as a philosophical movement ever becomes." By the late 1970s, its ideas were so generally recognized to be seriously defective that one of its own chief proponents, A. J. Ayer, could say in a interview: "I suppose the most important [defect]...was that nearly all of it was false.""
-And yet:
"Logical positivism was immensely influential in the philosophy of language and represented the dominant philosophy of science between World War I and the Cold War."
-So apparently it had little effect on the actual course of science or on the work of scientists during a period which saw perhaps the greatest scientific developments of all time. In other words, a main philo school of thought proved to be largely irrelevant to the discipline it was supposed to be serving. Gosh.

I think that would be a VERY profound point. And somehow you think there is no point here. Bloody weird that is.Only that isn't all you were claiming even if you didn't understand that.That is meaningless IF they transcend. Then they aren't within it, the Universe is DEPENDENT on it.

We MAY have freedom of choice, if the MultiWorlds hypothesis is wrong, but only experiment not logic can prove that. This is because your logic wasn't valid logic. You made two contradictory assumptions and in logic that is supposed to be able to make ANYTHING provable thus it is not a valid arguement.You don't have it.If neurons are PRE-determined by the laws of the Universe than you don't have freedom of choice. Logic and meaning INCLUDES both the possibility of pre or non determination for the neurons. Thus you either have or do not have freedom of choice depending on WHICH laws are functional in the Universe. You were attempting, unknowingly, to prove that ALL Universes MUST be non-determined.

Which is the point I am making. You did not prove your proposition. You failed because:
Logic and meaning support BOTH determinism AND non-determinism. However no Universe can be BOTH. Only experiment NOT logic can show which is true. And of course you had a contradiction which made the argument invalid.
Oh yes PLEASE start using better formatting. Monoblock posts are needlessly difficult to parse. Hit the enter key now and then. TWICE or you don't get white space and that is needed for visual clarity. Even when the logic isn't.
