This process frees energy in the form of light, which can be measured.By making multiple measurements (you need at least two for a date estimate) we can find out how much radiation the item was exposed to over the years and can get dating estimates related to when the item was last heated.
Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.Another absolute dating method is thermoluminescence, which dates the last time an item was heated.It is the only method that can be used to date rocks, pottery and minerals for dates that are approximately between 300 to 10,000 years old.The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.Scandinavian mythology claims the Kraken swallowed up whales and devoured ships.
It has been described as a huge version of an octopus or squid.
The ancients were cleverer than some people today assume.
They didn’t have rockets or electricity, at least no indisputable proof has been found of such technologies, but they did come up with technology that we don’t usually associate with the ancient world.
The Coso artifact is an object claimed by its discoverers to be a spark plug found encased in a lump of hard clay or rock on February 13, 1961, by Wallace Lane, Virginia Maxey and Mike Mikesell while they were prospecting for geodes near the town of Olancha, California, and long claimed as an example of an out-of-place artifact.
If a spark plug is encased in a 500,000-year-old "geode," this finding would represent a substantial scientific and historical anomaly, as spark plugs were invented in the 19th century.
Legends have even claimed the terrifying sea creature measured one-mile long.
