See Article History Astronomy, science that encompasses the study of all extraterrestrial objects and phenomena. Until the invention of the telescope and the discovery of the laws of motion and gravity in the 17th century, astronomy was primarily concerned with noting and predicting the positions of the Sun , Moon , and planets , originally for calendrical and astrological purposes and later for navigational uses and scientific interest. The catalog of objects now studied is much broader and includes, in order of increasing distance, the solar system , the stars that make up the Milky Way Galaxy , and other, more distant galaxies. With the advent of scientific space probes, Earth also has come to be studied as one of the planets, though its more-detailed investigation remains the domain of the Earth sciences. NASA The scope of astronomy Since the late 19th century astronomy has expanded to include astrophysics , the application of physical and chemical knowledge to an understanding of the nature of celestial objects and the physical processes that control their formation, evolution, and emission of radiation. In addition, the gases and dust particles around and between the stars have become the subjects of much research. Study of the nuclear reactions that provide the energy radiated by stars has shown how the diversity of atoms found in nature can be derived from a universe that, following the first few minutes of its existence, consisted only of hydrogen , helium , and a trace of lithium.
Radiometric Dating and the Geological Time Scale
How did Libby test his method and find out if it worked correctly? Libby tested the new radiocarbon method on carbon samples from prehistoric Egypt whose age was known. A sample of acacia wood from the tomb of the pharoah Zoser was dated for example.
The Minoan eruption of Thera, also referred to as the Thera eruption, Santorini eruption, or Late Bronze Age eruption, was a major catastrophic volcanic eruption with a Volcanic Explosivity Index (VEI) of 6 or 7 and a dense-rock equivalent (DRE) of 60 km 3 (14 cu mi), Dated to the mid-second millennium BCE, the eruption was one of the largest volcanic events on Earth in recorded history.
Two to three feet tall, and perfectly formed and proportioned no midget syndrome or deformed body parts. Perfectly formed human skeletons between 14 and 16 feet tall have been dug out of the fossil beds in the BOTTOM of the Grand Canyon in geological strata that the theory of evolution can’t explain their existence in. Incidentally, the Bible also records races of giants – remember Goliath at roughly nine feet tall?
Other skeletons of these giants have been unearthed on every single continent as well. Just google “Giant Skeletons” for pics for yourself, if you don’t believe me Some are apparently hoaxes, but ALL of them??? The nuclear war skewed the radiological dating standards but no one either realizes or will admit it. But the point is this. Generally speaking, the bigger a race is, the better its chances of survival, at least according to evolution LOL.
So why are all the big guys gone, and us little people still here?
Geology Glossary – Definitions of Geologic Terms
Santorini caldera Geological evidence shows the Thera volcano erupted numerous times over several hundred thousand years before the Minoan eruption. In a repeating process, the volcano would violently erupt, then eventually collapse into a roughly circular seawater-filled caldera , with numerous small islands forming the circle. The caldera would slowly refill with magma, building a new volcano, which erupted and then collapsed in an ongoing cyclical process.
That was how I came to to a member of the rescue mission to Union Bay, B.C., (south of Courtney on the Island Highway) to prepare Baldwin #14, for shipment to Snoqualmie, Washington.
Carbon , Radiometric Dating and Index Fossils Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things.
Carbon is a radioactive isotope of carbon. The half-life of carbon is approximately 5, years. The short half-life of carbon means it cannot be used to date fossils that are allegedly extremely old, e. The question should be whether or not carbon can be used to date any artifacts at all?
One of the very foundations of evolution and popular science today is the “geologic column. Although not found in all locations and although it varies in thickness as well as the numbers of layers present, this column can be found generally over the entire globe. Many of its layers can even be found on top of great mountains – such as Mt. Everest and the American Rockies. In some places, such as the mile deep Grand Canyon, the layers of the column have been revealed in dramatic display.
Certainly the existence of the column and its layered nature is quite clear, but what does it mean?

Carbon 14 is used for this example: This nullifies the carbon method as well as demonstrating that the earth is less than 10, years old. 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. In another creationist, Robert L. Whitelaw, using a greater ratio of carbon production to decay, concluded that only years passed since carbon started forming in the atmosphere! The argument may be compared to filling a barrel which has numerous small holes in its sides. We stick the garden hose in and turn it on full blast.
How Good Are Those Young-Earth Arguments?
Karst areas consist of chemically soluble rock such as limestone and gypsum. It can be associated with diamonds or gold. The size of the fragments ranges from sand- to cobble-size. The rocks that form from molten lava are classified as extrusive.
I am standing at the edge of a volcanic crater, just a careless step away from plunging fifty metres into a lake of incandescent orange lava that boils and hisses.
It is always a head scratcher — what gift to give that rail fan in your family or friends? My late Dad was a very accomplished and recognized amateur marine historian. The challenge was, to find a recent book about marine history or compilation on a particular tug company, as a gift at Christmas. He pasted away long before the Internet, but somehow, he managed to outsmart me on more than one Christmas by saying, “Well thank you Son.
But I have that book in my collection Thomas Hillebrant’s adoration for the Palouse Empire shines through in his newly released tome, “Palouse Rails: Granger Railroads of the Inland Northwest. A “Granger” is a farmer. These images capture the railroad equipment, locations, personnel, and operations that, for generations, have connected Inland Northwest agricultural regions with each other and with the world.

Activity increased in the mid s after about 50 years of quiescence, and the current eruption, which has been ongoing since January , has included frequent ash plumes and numerous episodes of lava-dome growth and destruction within the m-wide summit caldera. Multiple emissions of steam and gas occur daily, rising generally km above the 5.
Larger, more explosive events that generate ashfall in neighboring communities often occur every week. Activity through July was typical of the ongoing eruption with near-constant emissions of water vapor, gas, and minor ash, as well as multiple explosions every week with ash-plumes and incandescent blocks sent down the flanks BGVN
Welcome to the K12 section of the Radiocarbon WEBinfo site. The aim here is to provide clear, understandable information relating to radiocarbon dating for the benefit of K12 students, as well as lay people who are not requiring detailed information about the method of radiocarbon dating itself.
The feet do not have the mobile big toe of apes; instead, they have an arch the bending of the sole of the foot typical of modern humans. The hominins seem to have moved in a leisurely stroll. Computer simulations based on information from A. S2 is represented by only 1 print, but S1 left a track of prints, the first 4 of which are shown in the composite image, along with an analysis of step and stride lengths.
Further analysis indicated that individual S1 was considerably larger than any of the three individuals from site G. Other footprints and artifacts[ edit ] Other prints show the presence of twenty different animal species besides the hominin A. Rain-prints can be seen as well. Few footprints are superimposed, which indicates that they were rapidly covered up. Most of the animals are represented by skeletal remains discovered in the area. No artifacts have been found in the vicinity, at least within the ancient Laetolil Beds that contain the trackway.
However, artifacts from the younger Olpiro and Ngaloba Beds, also preserved at Laetoli, have been found.
