There are at least 3 ways that the age of the Universe can be estimated. I will describe The age of the chemical elements. The age of the oldest star clusters. The age of the oldest white dwarf stars. The age of the Universe can also be estimated from a cosmological model based on the Hubble constant and the densities of matter and dark energy. This model-based age is currently

Since such isotopes are thought to decay at consistent rates over time, the assumption Three geologists have reported what they called the first "successful" direct dating of dinosaur bone.

Mar 05, A comparison of the age of Earth, obtained from radioactive dating, and the age of the universe, based on galactic Doppler shifts, suggest that. 1. Earth is about the same age as the universe 2. Earth is immeasurably older than the universe 3. Earth was formed after the universe began 4. two dating methods contradict one another I'd like the answer and . The age of the Universe can also be estimated from a cosmological model based on the Hubble constant and the densities of matter and dark energy. This model-based age is currently +/- Gyr. But this Web page will only deal with actual age measurements, not estimates from cosmological models. Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over naturally-occurring isotopes are known.

Will this new radioisotope dating or radiodating technique solve the problems that plagued older A trio of geologists has published what they called the first successful direct dating of dinosaur bone. They used a new laser technique to measure radioisotopes in the bone, yielding an age of millions Most estimates For a Radioactive Decay Rates Not Stable.

Where thick sequences of sedimentary rock layers have been deposited in large basins, the deepest layers at the bottoms of the sequences may subsequently have become folded by earth movements when subjected Deep inside the Inner Gorge of Grand Canyon, northern Arizona, are the crystalline basement rocks that probably date back even to the Creation Week itself.

Clearly visible in the canyon walls are the Evolutionists generally feel secure even in the face of compelling creationist arguments today because of their utter confidence in the geological time scale.

Even if they cannot provide a naturalistic Two years ago it was reported that polonium Po radiohalos were still "a very tiny mystery. Investigating Polonium Radiohalo Occurrences. Andrew Snelling has undertaken a complete review of the significance of polonium and other For more than three decades potassium-argon K-Ar and argon-argon Ar-Ar dating of rocks has been crucial in underpinning the billions of years for Earth history claimed by evolutionists.

Perhaps no concept in science is as misunderstood as "carbon dating.

Nov 27, Enjoy Dr. Andrew Snelling's "Science Confirms a Young Earth - The Radioactive Dating Methods are Flawed" presentation from the ReEngage conference in Brisbane, Australia. To order resources from. Many different and complementary scientific measurements have established with near certainty that the universe and the Earth are billions of years old. Layers in glaciers show a history much longer than 10, years, and radiometric dating places the formation of the Earth at billion years. Light from galaxies is reaching us billions of. A comparison of the age of Earth obtained from radioactive dating and the age of the universe based on galactic doppler shifts suggests that _. A. Earth is about the same age as the universe B. The solar system and Earth formed billions of years after the universe began C. The two dating methods contradict one another D.

But, carbon dating can't be used to If the light has been traveling billions of years to reach us, then the universe must be at least that old. This is completely independent of radiometric dating of the solar system, but both methods point to an age of billions of years, not thousands. Not only can astronomers measure the distance of galaxies, they can measure how galaxies are moving.

Galaxies are not holding still in space, nor are they moving randomly. Some galaxies are moving towards their neighbors, attracted by their mutual gravity. But the biggest pattern we see is that galaxies are moving apart from one another.

This motion apart is not all at the same speed; instead it follows a pattern where galaxies that are further apart are moving more quickly. This particular pattern indicates the whole universe is expanding.

are not

To see why, consider a loaf of raisin bread. The raisins are like galaxies and the dough is like the fabric of space in the universe. As the dough rises, it carries the raisins along, pulling them apart from each other.

rather valuable

Raisins that started out on opposite sides of the loaf will be a few inches farther apart after the dough rises, while raisins that started out near each other may only move half an inch. So, the speed of their motion is proportional to the separation between them.

In the same way, the space of the universe pulls galaxies further apart as the universe expands.

apologise, but

When a galaxy is carried away by the expansion of space, its light waves are stretched out, making it appear redder.

From the measurements of many galaxies, astronomers can accurately measure the expansion rate of the universe as a whole.

Radioactive dating age of the universe

In the past the galaxies must have been closer together, and in the distant past they would have been packed together in a tiny point. If we assume that the expansion rate is constant over time, the age for the universe as a whole is about 10 billion years. However, astronomers have been working over the last 20 years to determine how the expansion rate changes with time.

We now know that early in the universe the expansion was slowing down, but now it is speeding up.

Radioactive Dating

Using careful measurements of this change in expansion rate, the age of the universe is now known quite precisely to be Many different and complementary scientific measurements have established with near certainty that the universe and the Earth are billions of years old.

Layers in glaciers show a history much longer than 10, years, and radiometric dating places the formation of the Earth at 4.

apologise, but

Light from galaxies is reaching us billions of years after it left, and the expansion rate of the universe dates its age to These are just a sampling of the types of evidence for the great age of the Earth and the universe; see the resources below for more.

Is either side right? The seven-day pattern in Genesis 1 is a literary device that serves the theological purposes of the author, rather than revealing information about the chronology of natural history.

The age of the Earth is estimated to be billion years ( ? 10 9 years 1%). This age may represent the age of the Earth's accretion, or core formation, or of the material from which the Earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial . For many people, radiometric dating might be the one scientific technique that most blatantly seems to challenge the Bible's record of recent creation. For this reason, ICR research has long focused on the science behind these dating techniques. Radiometric dating, radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which .

The story of the Genesis Rock reminds us of how biblical and scientific accounts, despite their different purviews and purposes, remain inexorably linked in our understanding of origins. The movie Is Genesis History? One really powerful piece of evidence for the old age of the universe consists of the leftovers of dwarf galaxies that were consumed by our Milky Way a long time ago.

Over the past century astronomers have studied planets, stars, and galaxies and have found many strands of evidence that the universe is billions of years old. The Hawaiian Islands offer a fascinating natural laboratory to test young earth and old earth models, including the reliability of radiometric dating.

The isotope Sr is called radiogenicbecause it can be produced by radioactive decay, while Sr is non-radiogenic. The Sr is used to determine what fraction of the Sr was produced by radioactive decay. After the rock has been solid for several billion years, a fraction of the Rb will have decayed into Sr See the talk.

When applied to rocks on the surface of the Earth, the oldest rocks are about 3. When applied to meteorites, the oldest are 4. This very well determined age is the age of the Solar System.

When applied to a mixed together and evolving system like the gas in the Milky Way, no great precision is possible. One problem is that there is no chemical separation into grains of different crystals, so the absolute values of the isotope ratios have to be used instead of the slopes of a linear fit.

This requires that we know precisely how much of each isotope was originally present, so an accurate model for element production is needed. One isotope pair that has been used is rhenium and osmium: in particular Re which decays into Os with a half-life of 40 billion years. But this is just the mean formation age of the stuff in the Solar System, and no rhenium or osmium has been made for the last 4. Thus to use this age to determine the age of the Universe, a model of when the elements were made is needed.

This is not surprising since the U has a shorter half-life, and the magnitude of the difference gives an estimate for the age of the Universe. DauphasNature,combines the Solar System U: Th ratio with the ratio observed in very old, metal poor stars to solve simultaneous equations for both the production ratio and the age of the Universe, obtaining A very interesting paper by Cowan et al. Normally it is not possible to measure the abundance of radioactive isotopes in other stars because the lines are too weak.

But in CS the thorium lines can be seen because the iron lines are very weak. Thorium decays with a half-life of It is actually probably slightly older because some of the thorium that would have gone into the Solar System decayed before the Sun formed, and this correction depends on the nucleosynthesis history of the Milky Way.
