How Old is Earth, and How Do We Know?
The same was long true of the cosmos. The ancient Greeks Eratosthenes and Aristarchus measured the size of the Earth and Moon, but could not begin to understand how old they were. With space telescopes, we can now even measure the distances to stars thousands of light-years away using parallax, the same geometric technique proposed by Aristarchus, but no new technology can overcome the fundamental mismatch between the human lifespan and the timescales of the Earth, stars, and universe itself.
Despite this, we now know the ages of the Earth and the universe to much better than 1 percent, and are beginning to date individual stars.
These methods are largely independent of each other, based on separate go back farther than the 10, years advocated by Young Earth Creationists, and the Age of the Earth and solar system from radiometric dating.
Creationist’s Blind Dates. The standard scientific estimate is that the universe is about 15 billion years old, the earth about 4. It is important to recognize from the start that there are independent procedures for obtaining each of these estimates, and that the procedures yield ranges of values that overlap. In the case of the universe, estimates can be obtained from astronomical methods or considerations of nuclear reactions.
Astrophysicists can measure the rate at which galaxies are receding and use these measurements to compute the time needed for the universe to expand to its present size. A second, independent, astronomical method is to use standard techniques to measure some parameters of stars mass, luminosity, compositor, and surface temperature , from which a well-confirmed theory of the life histories of stars enables physicists to compute their. Finally, considerations of radioactive decay make it possible to calculate the time at which certain heavy elements were formed.
These techniques are somewhat similar to the radiometric methods of dating rocks, which I shad consider in a little more detail.
Scientific Evidence for an Old Earth
A quick flash to a chart during the debate purportedly showing so, and far too much to read in a second, and then on to somethig else. Gish Gallop springs to my mischevious mind. So did Ham have a point that a piece of year old timber was found in a rock purportedly 45, years old?
Obviously scientists have determined some dates more accurately than others, but the Radiometric dating methods have long been a target of young-earth.
Carbon 14 is used for this example:, which was put out by Dr. The above is offered as a simple fact of research. Knowing how faulty creationist “facts” can be, let’s do a little research of our own. One suspects that the scientific world would not be using the carbon method if it were so obviously flawed. Could it be that the whole scientific community has missed this point, or is it another case of creationist daydreaming? This argument was popularized by Henry Morris , p.
How Science Figured Out the Age of Earth
In , the Institute of Creation Research ICR and the Creation Research Society initiated an eight-year research program to investigate the validity of radioisotope dating of rocks. Preliminary investigations carried out in the first three years were summarized in volume I of this work, published in For most interested parties, the final five pages of text, pp.
A nontechnical version of this book, authored by Donald DeYoung, and a video documentary have also been prepared.
The following material has been taken from a sheet entitled Several Faulty Assumptions Are Used in all Radiometric Dating Methods. Carbon 14 is used for this.
The age of the Earth, according to naturalists and old-Earth advocates, is 4. First, as we have shown elsewhere, the biblical narrative implies that the Universe was created with an immediate appearance of age in many ways. The trees of the Garden were bearing fruit so that Adam and Eve could eat from them, light from distant stars was viewable on Earth, and daughter elements 3 were possibly in the various rocks.
That said, while certain attributes of the Earth would appear old, the biblical model suggests that other features of the Universe would highlight its youth. Here are 21 such examples:. If the Bible is the inspired Word of God, then whatever it teaches can be known to be true—including what it teaches about the age of the Earth. Therefore, the age of the Earth is 6,, years.
Rock of Ages, Ages of Rock
While radiometric dating – find a woman. Find a woman online images of years. Rich man in the click image, geologists have rights to challenge the definitions resource on the earth.
Is there evidence to support the young-Earth creationists’ premise? Any old-Earth/evolutionary dating technique relies on the uniformitarian assumption.
You’ve got two decay products, lead and helium, and they’re giving two different ages for the zircon. For this reason, ICR research has long focused on the science behind these dating techniques. These observations give us confidence that radiometric dating is not trustworthy. Research has even identified precisely where radioisotope dating went wrong. See the articles below for more information on the pitfalls of these dating methods.
Radioactive isotopes are commonly portrayed as providing rock-solid evidence that the earth is billions of years old. Since such isotopes are thought to decay at consistent rates over time, the assumption is that simple measurements can lead to reliable ages. But new discoveries of rate fluctuations continue to challenge the reliability of radioisotope decay rates in general—and thus, the reliability of vast ages seemingly derived from radioisotope dating.
The discovery of fresh blood in a spectacular mosquito fossil strongly contradicts its own “scientific” age assignment of 46 million years. What dating method did scientists use, and did it really generate reliable results? For about a century, radioactive decay rates have been heralded as steady and stable processes that can be reliably used to help measure how old rocks are. They helped underpin belief in vast ages and had largely gone unchallenged.
Many scientists rely on the assumption that radioactive elements decay at constant, undisturbed rates and therefore can be used as reliable clocks to measure the ages of rocks and artifacts.
How are the ages of the Earth and universe calculated?
In telling of creation, the Bible writers never undertook to teach science. The Bible tells us that God made the world, and the universe, and that he sustains it continually, but it does not tell us how he did it or how long was the process. On this matter the Bible has been misunderstood. I’ve taken this passage from a sermon, which retired Berea College president William G.
The date is significant, because Frost delivered his message just five days after the conclusion of the Scopes Trial in Dayton, Tennessee. Substitute high school biology teacher John Scopes was convicted of violating the Tennessee statute that forbade the teaching of evolution in public schools.
But, much to the consternation of scientists, young-Earth creationism, the most frequently employed technique is radiometric dating, based on.
This value is derived from several different lines of evidence. Unfortunately, the age cannot be computed directly from material that is solely from the Earth. There is evidence that energy from the Earth’s accumulation caused the surface to be molten. Further, the processes of erosion and crustal recycling have apparently destroyed all of the earliest surface.
The oldest rocks which have been found so far on the Earth date to about 3. Some of these rocks are sedimentary, and include minerals which are themselves as old as 4. Rocks of this age are relatively rare, however rocks that are at least 3. While these values do not compute an age for the Earth, they do establish a lower limit the Earth must be at least as old as any formation on it. This lower limit is at least concordant with the independently derived figure of 4.
This involves measurement of three isotopes of lead Pb, Pb, and either Pb or Pb If the solar system formed from a common pool of matter, which was uniformly distributed in terms of Pb isotope ratios, then the initial plots for all objects from that pool of matter would fall on a single point. Over time, the amounts of Pb and Pb will change in some samples, as these isotopes are decay end-products of uranium decay U decays to Pb, and U decays to Pb
