Re: Summary
Such would be the case with Dr. Humphreys' cosmology.
Unfortunately for you Humphreys' "cosmology", while perhaps seeming reasonable to the uneducated and prejudiced audience he's aiming at, is incompatible with the observations and General Relativity. IOW, Humphreys is a psuedoscientific crank who knows not whereof he speaks.

Re: Summary
Jeez, I swear I submitted a reply, but it isn't here .. so here it is again.
Unfortunately for you Humphreys' "cosmology", while perhaps seeming reasonable to the uneducated and prejudiced audience he's aiming at, is incompatible with the observations and General Relativity.
Again with the assertions. Care toi give any specifics?
Sure. Note that the forum guidleines specifically state that it's acceptable to wait until requested to provide support ... but your practice of ignoring requests for support is not acceptable.
Hymphreys proposes that we once were inside a deep gravitational well, and that we are at the center of the Universe. There is absolutely no evidence for this claim. We obviously are not inside a deep gravitational well now, so how did the well go away? Magic. What caused it to form originally? Magic. Why don't we see the effect of that well on the light that was in transit while it existed? Magic. We do not observe any of the effects required for Humphreys' "cosmology" to be true (e.g. light blue-shifted to gamma rays).
As for General Relativity, this is a horrible medium for discussing such (because of the difficulty of writing equations), and I suspect you don't have the background to discuss it. However, there's lots of information available (including some rather feeble hand-waving rebuttals from Humphreys) at http://www.trueorigin.org/ca_rh_03.asp. I find it interesting that they omitted the obvious link to Page not found - Reasons to Believe.
IOW, Humphreys is a psuedoscientific crank who knows not whereof he speaks.
And who are you? I would love to see you debate Dr. Humphreys about his cosmology.
Well, I have a BSME and MSME from MIT, which required me to take several courses in physics (including relativity and basic QM), at which I did rather well. We used the Red Books as textbooks in some courses (of course, you must be familiar with the Red Books).
Debate? Most amusing. Science isn't done by debate. An exchange of written materials, preferably peer-reviewed, with plenty of time for research and reflection, is appropriate. Oh, wait, that's been done already. No need for me to spend the time doing it.

Re: Summary
e creos MUST relent to an old earth/universe. The scientific evidence is irrefuteable.
For YEC to maintain that God created it to look and be immensely old, but in fact it is not immensely old, is a position that does not deserve respect. This is a position of pure dogma.
There are eons and eons of time between Gen.1:1 and 1:2 according to the best theological scholarship. This doesn't mean 4-6 billion years necessarily.
I agree with you, God is guilty of fraud IF the YEC's are right - but they are not.
Well said. I have gained some respect for you with that post.
I don't agree with you about the exact distribution of the time as it relates to Genesis, but I'm not going to claim (or try to persuade you) that you are wrong.

Re: Summary
I don't agree that "There are eons and eons of time between Gen.1:1 and 1:2". I agree that there are eons and enos of time, but I do not believe that there is any correspondence between Genesis and the history of the Earth.
But I'm not going to make any attempt to persuade you; I don't proselytize religion, and I don't ahve any particularly persuasive arguments.

Re: Summary
JonF. have you even read what Humphreys proposes?
Yes.
The gravity well is gone due to the fact the white hole has emptied its contents.
What Humphreys proposes is not a white hole. And the "emptying of its contents" is an ad-hoc hypothesis for which there is no evidence. Of course, the original "white hole: is not compatible with our observations, e.g. of light that was in transit wnhe the "white hole" existed.
And where did the imagined singularity of the big bang come from? Magic. Again your double standards are obvious.
No. it's quite different. We admit that we don't know where the Big Bang came from ... but we have gobs of evidence that it happened, and we're working on where it came from. Humphreys has no evidence outside of his prejudices.
Humphreys has a PhD. in physics. It wasn't just a side course on his way to another degree.
Appeal to authority fallacy. The fact that he has a PhD leads us to think that he might know what he's talking about, but then examination of his work shows us conclusively that he doesn't know what he's talking about.
As for reasons to believe Humphreys has answered them and they refuse to debate him, even via written correspondence.
Really? Please explain how he has answered them, in your own words, and present evidence that RTB has refused to discuss the matter further. And debates or proposed debates don't count, science isn't done by debate.
Which would satisfy your criteria of peer review.
Nope. You don't understand peer review.
BTW there was a recent peer reviewed paper that supports some of Humphreys premises.
ROTFLMAO! You'll fall for anything, won't you! Of course, that paper (Shock-wave cosmology inside a black hole doesn't support Humphreys' lunacy at all. One of the authors was questioned about this and replied (as quoted at Re: Can anyone help me with this?, and with emphasis added by me):
quote:
Dear Adam:
Thanks for the e-mail and the interest in our paper. I do not think that the idea that some sort of time dialation reducing the age of the universe to 6000 years has anything whatsoever to do with our paper. In our paper, we explore the possibility that the explosion of the Big Bang that caused the outward motion of the galaxies, was an explosion of finite total mass, instead of the infinite mass explosion as touted by the standard model based on the Friedmann universe since the 1930'3. In our model, the explosion of the Big Bang generated a shock wave that went out from the center of the explosion, (like the outward shock wave of a nuclear explosion), and the expanding galaxies correspond to the region inside the outgoing spherical wave. What is new here is that when the shock wave is far enough out to be consistent with observations, (beyond one Hubble length--the distance light can travel since the Big Bang explosion), the whole explosion begins inside a (time reversed) black hole----a black hole in which everything is running backwards, exploding outward instead of collapsing inward. In our model, the universe eventually emerges from the black hole, and from then on expands like a huge finite ball of matter into empty space----we are inside the explosion, but to someone far out, this would look like a giant supernova explosion. It also follows from our model that information about the shock wave propagates inward from the shock wave, into the large central region of uniform expansion----and thus to an observer (like us) on the inside of the bubble, everything would look exactly like the Friedmann universe up until the time when the shock wave came into view from the farthest field of observations. In particular, up until the shock wave comes into view, everything looks the same as in the Friedmann model, inclulding the age of the universe---so I see no connection to a new idea on the age of the universe.
We believe that there very likely is such a shock wave out there---and that a model like ours is pretty much forced on you once you assume that the Big Bang was an explosion of finite total mass. (Assuming finite mass, the only other alternative is that the spacetime is not simply connected--this was the topic of Geoffrey Weeks talk in Berkeley last monday. We think this is much less likely that the existence of a wave way out there.) Our model shows that if this shock wave were close enough, it could conceivably have already come into view---that is, could be visible in the far field in the direction nearest the wave. We expect that this would be a region in the sky of lower temperature. (Shock waves always propagate into regions of lower density and pressure, so the temperature would be lower on the far side of the shock----that radiation would reach us when the wave came into view----when the shock wave got within one Hubble length of us.) One of the questions asked of Jeffry Weeks last Monday, was the question of whether there is a center to the universe, and he answered, based on the standard model---and his non-simply connected version of it--- there is no center. In our model, it is much more mundane---there is a center---but within the bubble like region near the center before the wave has appeared, all points ``appear'' the same observationally.
As far as we know, no one has ever looked for the shock wave at the edge of the expanding galaxies. We are researchers coming from the mathematical theory of shock waves, and this work is very controversial, and not accepted by cosmologists---although we have given many international talks explaining this model, and have heard no physical observation that rules this model out. To us, the FINITE explosion part makes a whole lot more physical sense than other alternatives.
You can download my radio interview on Quirks and Quarks and NPR, and some popular articles on this from my web page: Index of /~temple/articles
Good luck with your argument!
Blake Temple
IOW, they wrote a purely theoretical paper proposing a model in which the universe is 14-ish billion years old, in which everything we see is identical to the standard model, but predicts that at some time in the future we might see something that differs from what the standard model predicts.
So, why don't you explain to us exactly how this paper supports Humphreys?
Still waiting for your reply in Distinguishing Pb from Pb???.

Re: Summary
We do not even know what causes atoms to be unstable and decay.
I'm not so sure about that. Nevertheless, we can measure the rate of decay and there is no known mechanism by which that rate can be changed so that you can turn a Ga date to a Ka date.
In some sense we don't know what causes atoms to be unstable and decay, and in some sense it appears that we never will; every layer of the atomic onion that we peel has so far revealed another layer underneath.
However, QM predicts radioactive decay, and is probably the most accurate and well-tested scientific theory ever. A change in radioactive decay rates would mean that QM is wildly wrong.
To amplify on "no known mechanism" IMHO it's worthwhile pointing out that lots of mechanisms have been tested, singly and in combination.

Re: Wasssup????????
But, GOD created ADAM as a fully grown man. The trees were already grown when He created them. Adam wasn't a baby growing up in the dark wilderness awaiting the light to get there. It was created that way. No waiting
That argument, known as "Omphalos" or "appearance of age", has been soundly rejected by essentailly all theologians, including most YEC theologians. If indeed God created Adam, there were good reasons for creating him as a full-grown-man; but the only reason for creating light in transit (and all the other indications of old life, old Earth, and old Universe) is to deceive us. Nobody seems to want to worship God the deceiver.
C-14 and K-40 dating - (not really a trick just a little tricky)The C-14 method has a half life of 5730 years and a second one of 1.3 billion years. The problem is that the system of equations for the radioactive decay is not mathematically definite.
For those two systems, yes. However, the premises (I don't like to call them assumptions because that implies that they haven't been checked) have been checked and cross-correlated with other methods. Those two methods might be wrong once in a while, but they are not wrong often.
In addition, the vast majority of radiosotope dates are carried out by other methods, such as isochron methods and concordia-discordia methods. These are mathematically definite.
I discuss this more here. If you are interested in finding out how radioisotope dating works, and exactly why Hagemann's claims are so silly, see Radiometric Dating: A Christian Perspective
#'s 1 and 2 were taken from an article written by Fritz Hagemann. He is here from Germany for NATO AWACS as a NATO Liason Officer. He used to teach the "Big Bang Theory" and is in Aeronautics and Space Engineering. It was written in "Ha Shofar" a newsletter from the Kehilat ROSH PINAH congregation.
Well, he should not write about radioisotope dating; he obviously doesn't know much of anything about it.

Re: Topic
Could everyone get back to the topic at hand.
OK.
There's an interesting new article at The Origin of Iodine-129: By Physics or Fantasies?. It reviews the arguments about the absence of short-lived isotopes and discusses an attempt by Woodmorappe/Peczkis to address the issue of one particular isotope.

Re: God created a man, not an embryo
Start with Pre-1900 Non-Religious Estimates of the Age of the Earth. SOme ages well under 4.5 By, a few over it, all reflecting the imprecision of the non-radiometric tools ... but all far greater than a YEC scenario.
Full references available in "The Age of the Earth", G. Brent Darlymple.
Anyway, to answer the original post question: What is the YEC answer to the lack of shorter lived isotopes?
My personal answer: At, during, or shortly after creation, before life was introduced to the world, the rate of radioactive decay was significantly higher than it currently is. This was not done to "fool" anyone, but to provide the perfect environment for life and Man.
Just to reinforce what's already been siad: that's not compatible wwith the observed evidence.
