People smart women have hard time dating

Join Now The first time I heard about your site it was through a friend and I didn't think Sex Search or sex dating would be for me.
I'm not trying to be non-committal when I say that we don't have a hard preference one way or the other, but we truthfully don't.

Thus, we clear away the first illusion spun by creationism, namely that most of the dates are bad, that the radiometric picture is totally chaotic.

But if light were billions of times faster at the beginning, and slowed down in transit, there would be no more problem.

very rapid early on, gradually easing to stabilize at today’ value for c, just a few decades ago.

outlining this, and answering several arguments raised against the theory.

He claimed that rather than fluctuating around both sides of the present value as measurements became more accurate, they had progressively declined from a point significantly higher than today’s value.

He proposed that this decline had been exponential in nature, i.e.

The other is that the decay products of various atoms are always the same. Just looking at this list, I can see that none of these are actually assumptions used by radioactive dating methods and/or they are known issues and compensated for. Something that this particular website has none of. Basically, just like all creationists, they are making stuff up and then hoping you won’t check them on it. 1) atmosphere has always had the same amount of C-14 This is obviously in reference to carbon-14 dating of formerly living tissue.

This is also actually kind of trivial and easily determined in the lab. Let’s see what the Missing Universe Museum thinks are the assumptions of radioactive dating methods. I guess we have to start at the top and work our way down… During an organisms life, it takes in CO have the common 6 protons and 6 neutrons. However, due to some interesting nuclear chemistry (which I’ll go into if requested), there’s another version of carbon (called an isotope) that has 6 protons and 8 neutrons. Note that if the number of protons change, then the atom is no longer carbon. Amazingly (and unlike what is claimed by the creationists), scientists have known about a variety of methods that create carbon-14 and how those methods have varied over time. Well, we take a carbon sample from a material of a known age and date that. Basically, the calibration curves are off by no more than 16 years over the historical range (6,000 years or so) and no more than 163 years over the last 20,000 years.

He plots Woodmorappe's collection of anomalous radiometric results and notices something remarkable.Look at the various radiometric tables in use over the last 20 years or so and you will find, at least for the fossil-bearing strata, a remarkably tight agreement. Did the geochronologists throw darts to determine the accepted dates?(Matson, 1993, p.1) Either we have a worldwide conspiracy among geologists, which no sane person believes, or else the numerous radiometric dates were consistent enough to allow that kind of close agreement. Dalrymple, an expert in radiometric dating with lots of hands-on experience, puts the percentage of bad dates at only 5-10 percent.Keep in mind that, in order to be useful for validating an age of the universe less than 10,000 years rather than more than 10 billion years, the speed of light needs to be more than a million times faster, a difference which would be difficult to miss.We're not talking about a difference of a fraction of a percent.is a pseudoscientific creationist cosmology put forward by cdesign proponentsists.It attempts to solve the starlight problem by claiming that the speed of light in a vacuum was faster in the past and has since decayed to the value we observe it to be today.Woodmorappe (1979), with his collection of some 350 bad radiometric dates, must surely be the master of that technique.Upon being presented with claims that radiometric dating is totally erroneous, a question naturally arises: If radiometric geochronology is half as bad as Woodmorappe's list suggests, then how in the world did geologists ever arrive at a tight consensus for the official dates?Eat one of those and your tummy will curl right up!Seriously speaking, a favorite attack on radiometric dating involves dangling "horror stories" about gross errors before the reader, thus giving the impression that radiometric dating is totally unreliable.
