Uranium/lead dating provides most accurate date yet for Earth’s largest extinction

This belief in long ages for the earth and the existence of life is derived largely from radiometric dating. These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio. This age is computed under the assumption that the parent substance say, uranium gradually decays to the daughter substance say, lead , so the higher the ratio of lead to uranium, the older the rock must be. Of course, there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, as well as daughter product being present at the beginning. Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating. Radiometric dating is largely done on rock that has formed from solidified lava. Lava properly called magma before it erupts fills large underground chambers called magma chambers. Most people are not aware of the many processes that take place in lava before it erupts and as it solidifies, processes that can have a tremendous influence on daughter to parent ratios. Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger.

Updated 8 January c Introduction In a related article on geologic ages Ages , we presented a chart with the various geologic eras and their ages. In a separate article Radiometric dating , we sketched in some technical detail how these dates are calculated using radiometric dating techniques. As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.

Uranium–uranium dating is a radiometric dating technique which compares two isotopes of uranium (U) in a sample: uranium ( U) and uranium ( U). It is one of several radiometric dating techniques exploiting the uranium radioactive decay series, in which U undergoes 14 alpha and beta decay events on the way to the stable.

His calculations did not account for heat produced via radioactive decay a process then unknown to science or, more significantly, convection inside the Earth, which allows more heat to escape from the interior to warm rocks near the surface. For biologists, even million years seemed much too short to be plausible. In Darwin’s theory of evolution , the process of random heritable variation with cumulative selection requires great durations of time. According to modern biology, the total evolutionary history from the beginning of life to today has taken place since 3.

Huxley , attacked Thomson’s calculations, suggesting they appeared precise in themselves but were based on faulty assumptions. The physicist Hermann von Helmholtz in and astronomer Simon Newcomb in contributed their own calculations of 22 and 18 million years respectively to the debate: However, they assumed that the Sun was only glowing from the heat of its gravitational contraction. The process of solar nuclear fusion was not yet known to science. In John Perry challenged Kelvin’s figure on the basis of his assumptions on conductivity, and Oliver Heaviside entered the dialogue, considering it “a vehicle to display the ability of his operator method to solve problems of astonishing complexity.

Charles Darwin ‘s son, the astronomer George H. Darwin , proposed that Earth and Moon had broken apart in their early days when they were both molten. He calculated the amount of time it would have taken for tidal friction to give Earth its current hour day. His value of 56 million years added additional evidence that Thomson was on the right track. Radiometric dating Overview By their chemical nature, rock minerals contain certain elements and not others; but in rocks containing radioactive isotopes, the process of radioactive decay generates exotic elements over time.

See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C dating usually want to know about the radiometric [1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days?

Christians , by definition, take the statements of Jesus Christ seriously. This only makes sense with a time-line beginning with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. We will deal with carbon dating first and then with the other dating methods. How the carbon clock works Carbon has unique properties that are essential for life on Earth.

Uranium, on the other hand, is so well studied that its decay constant is much better known, making the U/Pb dating technique more accurate, Mundil noted. U/Pb dating relies upon the decay of naturally occurring uranium and different isotopes of lead.

Share by Mail The question of the meaning and proper interpretation of the early chapters of Genesis is one of the most heated subjects in Christendom today. Few other topics have evoked such polarised opinion and division. The diversity of views on Genesis, even among the most learned of exegetes and scholars, is staggering. While one extreme insists that the days of Genesis must strictly be interpreted as seven consecutive hour periods thus rendering the earth very young indeed — in the order of thousands, and not millions or billions, of years old , at the other extreme lies the notion that the early chapters of Genesis are devoid of any historical content at all.

There is a plethora of competing views which reside in the middle of those polar extremes: In this article, I attempt to show that, while it is possible to interpret the book of Genesis in light of a young earth, there is no Biblical mandate for this conclusion: That is to say, Genesis could be interpreted in that manner, but it does not have to be. And, as a scientist, the arguments for an ancient earth seem to be very compelling needless to say, when it comes to Darwinian evolution, it is a very different story.

Having shown that Genesis does not require that one read it as conveying a young earth, I hope that readers will be convinced that we can thus read and understand the science on its own terms as well. It seems to me that there are three major subtopics which an article of this nature must address. The proper interpretation of Genesis One. The question of the fall of man, human sin and its consequences.

The report said members of the committee, including Clinton, should have known about the investigation and it questioned why they would have approved it. The segment infuriated Fox News viewers who demanded Smith be fired In his segment, Smith then stated what the allegations against Clinton were. A committee of nine evaluated the sale, the president approved the sale, the Nuclear Regulatory Commission and others had to offer permits, and none of the uranium was exported for use by the US to Russia.

Attorney General Jeff Sessions left said Monday that prosecutors were looking into whether a special counsel should be appointed to investigate Republican concerns including an investigation of the Clinton Foundation dealings ‘I feel like [Fox News is] actually CNN fake news when Shepard Smith is on,’ tweeted another viewer. The clamor on the right for an investigation against Clinton is putting pressure on the attorney general, Jeff Sessions.

Sessions said Monday that prosecutors were looking into whether a special counsel should be appointed to investigate Republican concerns. In a letter to the House Judiciary Committee, which is holding an oversight hearing Tuesday, the Justice Department said Sessions had directed senior federal prosecutors to ‘evaluate certain issues’ recently raised by Republican lawmakers.

If prosecutors do appoint a special counsel, speculation could arise with regards to the independence of federal investigations under President Trump. The list of matters he wants to look into vary but include the FBI’s handling of the investigation into Hillary Clinton’s use of a private email server while she was secretary of state.

May 17, Michael Rogalski For 60 years, American drivers unknowingly poisoned themselves by pumping leaded gasoline into their tanks. Here is the lifelong saga of Clair Patterson—a scientist who helped build the atomic bomb and discovered the true age of the Earth—and how he took on a billion-dollar industry to save humanity from itself. He was queasy, not out of his mind. But on a mild October night in , shortly after Dymock groggily tucked himself into bed, something within him snapped. Like a man possessed, Dymock rose, fumbled through the dark, opened his window, and leapt into his garden.

Hours later, a passerby discovered him lying in the dirt, still breathing. He was hurried to a hospital. Many of his coworkers were acting erratically too. One night that same week, he had arrived home feeling ill. By sunrise, he was thrashing at phantoms. His family rang the police for help—it would take four men to wrap him in a straitjacket. A few miles away, Herbert Fuson was also losing his grip on reality.

He’d be restrained in a straitjacket, too. The most troubling case, however, belonged to Ernest Oelgert.

Some of the test and monitoring equipment for the military was the best that could be produced at the time and no expense was spared in its construction. At the budget-built end, there were the countless test-gadgets intended for radio repairmen or radio hobbyists that might seem to barely be able to perform the intended task but clever designs sometimes resulted in very useful test instruments.

Biddle of Philadelphia imported these instruments and each box has his tag attached. Biddle was also a very early major builder and supplier of wireless equipment with Reginald Fessenden being one of his prominent customers over a long period of time. At the turn of the last century, many precision measurements had to be calculated because the measurement couldn’t be made directly since many of the instruments we take for granted today hadn’t been developed.

A known precision resistance allowed one part of the equation to be selected and the remainder was then calculated. These types of boxes were used in DC Resistance bridge circuits for precise measurements of an unknown resistance Wheatstone Bridge circuits or in other circuits for calculating current flow, low voltage levels or comparison evaluations. Many experiments were carried out at Mt. Wilson and the facility there had has a lot of very early test gear.
