More Young Earth Evidence.

[Ark Guy]

When uranium decays to lead, a by-product of this process is the formation of helium, a very light, inert gas which readily escapes from rock

 

[Ark Guy]

Certain crystals called zircons, obtained from drilling into very deep granites, contain uranium which has partly decayed into lead.

 

[Ark Guy]

By measuring the amount of uranium and ‘radiogenic lead’ in these crystals, one can calculate that, if the decay rate has been constant, about 1.5 billion years must have passed. *(This is consistent with the geologic ‘age’ assigned to the granites in which these zircons are found.)

 

[Ark Guy]

There is a significant amount of helium from that ‘1.5 billion years of decay’ still inside the zircons.* This is at first glance surprising for long-agers, because of the ease with which one would expect helium (with its tiny, light, unreactive atoms) to escape from the spaces within the crystal structure.* There should surely be hardly any left, because with such a slow buildup, it should be seeping out continually and not accumul

 

[Ark Guy]

Drawing any conclusions from the above depends, of course, on actually measuring the rate at which helium leaks out of zircons.* This is what one of the RATE papers reports on.* The samples were sent (without any hint that it was a creationist project) to a world-class expert to measure these rates.* The consistent answer: the helium does indeed seep out quickly over a wide range of temperatures.* In fact, the results show that because of all the helium still in the zircons, these crystals (and since this is Precambrian basement granite, by implication the whole earth) could not be older than between 4,000 and 14,000 years.* In other words, in only a few thousand years, 1.5 billion years’ worth (at today’s rates) of radioactive decay has taken place.** Interestingly, the data have since been refined and updated to give a date of 5680 (+/- 2000) years.

1. The measurements cannot account for how much helium diffuses into the zircons.

2. Producing a billion years of radioactive decay in only 10,000 years or so would have produced a billion years worth of heat from radioactive decay as well. This would pretty much vaporize the earth.

Perhaps, it would be wise to check out the talk origins archive to check to see if an arugment as been refuted before you post here. It only took me a minute to check it out. That is far less than the time that will be wasted by those who will read this thread.

Since Ark Guy I am sure still has me on ignore, but I shall say it anyway.

He posts repeatedly the same material that has been oft refuted. I am on ignore because I challenged him on his education in these matters. As he clearly has little to no scientific knowledge. He is the posting equivalent of a 'back slapper'. He just posts anything YEC no matter how ludicrous because it states what he so wishes to be true. And his lack of scientific knowledge doesn't allow him to separate the ridiculous from the germane.

You're welcome, Chi.

Still waiting for a refute.

So far it seems like the earth is young after all...just like the bible tells us.

Score another for God and the bible and His young earth.

Do you have everyone on ignore?

Even if this research was valid (which it is not) consider the following.

YEC's account for this with an event of 'accelerated decay' to account for the materials being present.

The existence of the helium could just as easily be accounted for in an old earth model with an event of 'decellerated diffusion'.

So this research, if submitted to the same type of radical changes in observable mechanisms such as radioactive decay or helium diffusion, means nothing because an ad-hoc explaination can be used (which is the heart of the YEC's conclusions - accelerated decay).

This is a good example of why science only accepts looking at the way things happen today as how they happened in the past, unless there is good reason or evidence to point to a different conclusion. There is currently no evidence or reason (in fact there are several reasons not to) to consider an accelerated decay in the past.

This evidence fits nicely into an old earth scenario following an episode of 'decellerated diffusion' of helium from zircons.

What about post 6 - Fragmentsofdreams' reply? Seems like a good refuatation to me, and if you think it is not then please explain why.
There is also now notto's post to deal with.

If Ark Guy responded to evidence we would have been done with him months ago.

Good Luck Ark Guy!

Try not to get knuckle burns on the way out.
