Antarctic radioactive dating of meteorites

There are records of several persons being hit by meteorites.

Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.Scientists say they have developed a means of accurately dating Earth's oldest and densest polar ice by analyzing the composition of krypton gas trapped within ancient air bubbles.In a study published Monday in the journal PNAS, researchers used the new dating method, called Atom Trap Trace Analysis, or ATTA, to study ice recovered from the Mc Murdo Dry Valleys in Antarctica."The oldest ice found in drilled cores is around 800,000 years old, and with this new technique we think we can look in other regions and successfully date polar ice back as far as 1.5 million years," lead study author Christo Buizert, an Oregon State University paleoclimatologist, said in a statement."That is very exciting because a lot of interesting things happened with the Earth's climate prior to 80,000 years ago that we currently cannot study in the ice core record," Buizert said.Nevertheless, there is substantial evidence that the Earth and the other bodies of the Solar System are 4.5-4.6 billion years old, and that the Milky Way Galaxy and the Universe are older still.The principal evidence for the antiquity of Earth and its cosmic surroundings is: Spontaneous breakdown or decay of atomic nuclei, termed radioactive decay, is the basis for all radiometric dating methods.Radioactivity was discovered in 1896 by French physicist Henri Becquerel.

By 1907 study of the decay products of uranium (lead and intermediate radioactive elements that decay to lead) demonstrated to B. Boltwood that the lead/uranium ratio in uranium minerals increased with geologic age and might provide a geological dating tool. Meteoroids which is what the rock is called when it is still in space are cold.During their passage through the atmosphere they heat and melt on the outside but the time is so short that they are burning the insides of the stones remains cold.He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.While is it possible that they may hit something upon landing and that could create a fire it is not because the meteorite itself landed hot.
