How long can carbon dating go back Answers to Creationist Attacks on Carbon-14 Dating

How long can carbon dating go back, the assumptions of carbon dating

If that's not true, GR doesn't work.

The ions are accelerated and passed through a stripper, which removes several electrons so that the ions emerge with a positive charge. It is doubtful that other radiometric dating techniques such as potassium-argon or rubidium-strontium will ever be of much value or interest to the young-earth creationist who desires to develop further our understanding of the past because they are only applicble on a time scale of millions or billions of years.

Outside the range of recorded history, calibration of the 14 C "clock is not possible. Physics major, but in the end, I don't think this works. Science What Is Science? Versus, of course, nowhere near the sun.

Other factors affecting carbon dating

A supernova is an explosion of a massive star—the explosion is so bright that it briefly outshines the rest of the galaxy. Animals, including humans, consume plants a lot and animals that consume plantsand thus they also tend to have the same ratio of carbon 14 to carbon 12 atoms. I suppose this is only tangentially related, but it's a question I've been thinking about for a while now, and I don't think it's worth its own thread. In order to actually do the dating, other things need to be known. K decay also forms plenty of beta radiation. Footnote 14 lists many instances.

Efforts by creationist scientists to obtain the raw data from which the oldest tree-ring chronology has been constructed to investigate this how long can carbon dating go back source of bias have so far not met with success. Contamination is of particular concern when dating very old material obtained from archaeological excavations and great care is needed in the specimen selection and preparation. Afterward the gas is stored in a tube insulated by Mercury and Lead, so as to minimize the chances of the sample being affected by radiations from the atmosphere.

However, the discrepancy has turned out to be very real. Gentry has researched radiohalos for many years, and published his results in leading scientific journals.

by Gerald A. Aardsma, Ph.D.

The level of proof demanded for such stories seems to be much less than for studies in the empirical sciences, such as physics, chemistry, molecular biology, physiology, etc. Similar questions can also arise in applying Sm-Nd [samarium-neodymium] and U-Pb [uranium-lead] isochron methods. Doubting simply so you can wag your finger and say "Nuh uh" isn't having an open mind -- it's simply being contrary. Basically, by making even a small change in any fundamental particle, the whole puzzle gets tossed out the window.

Carbon dating, rate of decay, how far can we go?

It is assumed that the ratio of 14 C to 12 C in the atmosphere has always been the same as it is today 1 to 1 trillion. Measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying 14 C atoms in a sample.

You may have misunderstood your physicist friend.

The method involves dividing both the parent and daughter concentrations by the concentration of a similar stable isotope—in this case, strontium Are half-life constants truely constant? The gas is then subjected to more purifying procedures.
