The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.

We are told that these methods are accurate to a few percent, and that there are many different methods.

Probably India did not have a clear local name earlier because, like China , it seemed to be the principal portion of the entire world, and so simply the world itself. Sumeru or Meru , the only one inhabited with humans identical to us. The only question was how much of it was taken up by India. Indeed, India was once an island in the Mesozoic Ocean, but it moved north and collided with Asia. In Chinese, we get various ways of referring to India. The modern form, , renders the name phonetically with characters of no particular semantic significance “print, stamp, or seal” and “a rule, law, measure, degree”.

The older practice, however, was dedicated characters that might have a larger meaning. Thus, we get or , in which can be a kind of bamboo but otherwise is just used for India. Thus we get expressions like , “Sanskrit,” , “Sanskrit characters. The rule of the Sult.

What Is a Supernova?

Taylor Site, Paluxy Riverbed, , Glen Rose, TX The Taylor Site contains several trackways of largely infilled, metatarsal dinosaur footprints once considered human by many creationists, and a trail of deeper, more typical digitigrade dinosaur tracks. Click image for larger view. Photograph C , Glen J. At one time many YECs argued that such tracks supported their belief that all life forms were created only several thousand years ago, dramatically contradicting the conventional geologic time table that humans did not appear on earth until over 60 million years after non-avian dinosaurs became extinct.

Can science prove the age of the earth? No scientific method can prove the age of the earth and the universe, and that includes the ones we have listed here. Further, it has to be assumed that the clock was never disturbed. There is no independent natural clock against which those assumptions can be tested. For example, the amount of cratering on the moon, based on currently observed cratering rates, would suggest that the moon is quite old. However, to draw this conclusion we have to assume that the rate of cratering has been the same in the past as it is now.

And there are now good reasons for thinking that it might have been quite intense in the past, in which case the craters do not indicate an old age at all see below. No scientific method can prove the age of the earth or the universe, and that includes the ones we have listed here. Ages of millions of years are all calculated by assuming the rates of change of processes in the past were the same as we observe today—called the principle of uniformitarianism.

If the age calculated from such assumptions disagrees with what they think the age should be, they conclude that their assumptions did not apply in this case, and adjust them accordingly. If the calculated result gives an acceptable age, the investigators publish it. Examples of young ages listed here are also obtained by applying the same principle of uniformitarianism.

Long-age proponents will dismiss this sort of evidence for a young age of the earth by arguing that the assumptions about the past do not apply in these cases. In other words, age is not really a matter of scientific observation but an argument about our assumptions about the unobserved past.

In , Carl Otto Lampland was the first to announce that he had seen changes in the structure of the Crab Nebula. Their nature, size and distance were subject to debate. Observing changes in such objects allows astronomers to determine whether their spatial extension is “small” or “large”, in the sense that notable fluctuations to an object as vast as our Milky Way cannot be seen over a small time period, such as a few years, whereas such substantial changes are possible if the size of the object does not exceed a diameter of a few light-years.

Lampland’s comments were confirmed some weeks later by John Charles Duncan , an astronomer at the Mount Wilson Observatory. He benefited from photographic material obtained with equipment and emulsions that had not changed since ; as a result the comparison with older snapshots was easy and emphasized a general expansion of the cloud.

Edit Amar firing a photon torpedo at an unknown cloud In Klingon space, three Klingon K’t’inga-class battle cruisers are patrolling an area and encounter a huge cloud-like anomaly. On the bridge of IKS Amar , the Klingon captain orders his crew to fire torpedoes at it, but they have no effect. The captain immediately orders retreat.

Meanwhile, in Federation space, a listening post, Epsilon IX , picks up a distress signal from one of the Klingon ships. As the three ships are attempting to escape the cloud, a “bolt” of plasma energy emerges and destroys each ship one by one.

Kepler’s Supernova: We can date Kepler’s Supernova, because Johannes Kepler watched it in and said it was visible in the daytime for three weeks. It was a Type 1a supernova, the kind cosmologists use to measure the size and expansion rate of the universe.

Radioactive decay[ edit ] Example of a radioactive decay chain from lead Pb to lead Pb. The final decay product, lead Pb , is stable and can no longer undergo spontaneous radioactive decay. All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus. Additionally, elements may exist in different isotopes , with each isotope of an element differing in the number of neutrons in the nucleus.

A particular isotope of a particular element is called a nuclide. Some nuclides are inherently unstable. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide. This transformation may be accomplished in a number of different ways, including alpha decay emission of alpha particles and beta decay electron emission, positron emission, or electron capture.

Another possibility is spontaneous fission into two or more nuclides. While the moment in time at which a particular nucleus decays is unpredictable, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life , usually given in units of years when discussing dating techniques. After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a “daughter” nuclide or decay product. In many cases, the daughter nuclide itself is radioactive, resulting in a decay chain , eventually ending with the formation of a stable nonradioactive daughter nuclide; each step in such a chain is characterized by a distinct half-life.

In these cases, usually the half-life of interest in radiometric dating is the longest one in the chain, which is the rate-limiting factor in the ultimate transformation of the radioactive nuclide into its stable daughter. Isotopic systems that have been exploited for radiometric dating have half-lives ranging from only about 10 years e.

Age of the earth

As it happens, not very well. The number of Supernova Remnants SNRs observable in the Galaxy is consistent with the number expected to be formed in a Universe that is 7, years old. However, using Davies’ own methodology, the actual number of observable SNRs in our Galaxy from Green gives a value of 11, years, not 7, years. The 11, is the lowest possible value for the age of the Universe as derived from his methodology. Yet a strict reading of the lineages in Genesis gives the date of creation as being BC, about 6, years ago as famously calculated by Archbishop Ussher of Armagh in the 17th century.

His calculations are repeated here, using his values for convenience, any fractions are rounded to the nearest whole number – it makes very little difference to the results:

They watched a star in a far-off galaxy first grow so huge it was bigger than our entire solar system – that’s from the sun all the way out to far-off Pluto – and then collapse and explode. And it kept exploding, over and over again, for almost two years.

Some are so bright they are visible with the naked eye. When a smaller star like our sun runs out of fuel, it fizzles out with a whimper. But the bigger they get, the more that gravity pulls on them. They eventually get too big, and gravity forces them to collapse in on themselves. But it’s only supposed to explode once. But as the team observed iPTF14hls, they saw it was much more spectacular. And the supernova wasn’t fading — it appeared to still be exploding.

Six hundred days is already a record, but remarkably the star’s explosive death may have even stretched over decades. When the research team submitted their discovery to Nature, they originally included some theories on what might be going on.

The strange phenomenon was possible because light from the exploding star bent through a galaxy before reaching Earth. The intervening galaxy, which sits 2 billion light years from Earth, magnified the explosion’s brightness 50 times to give astronomers an unprecedented view of the Type 1a supernova, which the team have called ‘iPTF16geu’.

Scroll down for video This image shows the gravitationally lensed type 1a supernova iPTF16geu as seen with different telescopes. Optical light observation of iPTF16geu and its surroundings. Galaxies bend light through an effect called ‘gravitational lensing’ that helps astronomers peer deeper into the cosmos. One of the foundations of Einstein’s theory of general relativity is that mass curves the surrounding space-time.

This curve can create a ‘lens,’ deflecting the path of passing light and magnifying any objects on the other side. This created an ‘image’ of the supernova at four different points on Earth’s surface. For astronomers to benefit from this phenomenon, a sufficiently massive foreground object must align precisely with the background target they wish to study.

Type 1a supernovae are important to study because they can tell astronomers more about the rate that the universe is expanding and how matter is scattered around the galaxy. They are often referred to as ‘standard candles’ because of their well-known intrinsic brightness. Finding a magnified, or ‘gravitationally lensed’, Type 1a supernova is like discovering a brighter candle with which to view the universe.

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.

That’s it. Literally, a supernova is an exploding star. The star explodes in a massive explosion, resulting in an extremely bright and short-lived object that emits .
