The first method of finding the absolute age of an object is by examining tree rings.If we looked at a cross-section ofa tree or log we would notice that all through it are concentric circles radiating out from the center to the bark. Each ring is also different, and the thickness of each ring is representative of the length of the growing season.The first compares the integrated broad/narrow-band photometry (e.g. The fourth and final broad category is the use of specific spectral features that are due to a unique stellar evolutionary phase with known beginning time and duration.While each technique requires accurate models of stellar evolution and spectral synthesis – of which our understanding and techniques continue to develop – the main difference is observational. This type of technique is particularly attractive, as it avoids the complexities of modelling a full stellar population, and focusses on a single stellar evolutionary phase.
We apply this technique to a photometric catalogue of YMCs in M83.
For since the fathers fell asleep, all things continue as they were from the beginning of creation.” For this they willfully forget: that by the word of God the heavens were of old, and the earth standing out of water and in the water, by which the world that then existed perished, being flooded with water.
Most scientists and many Christians believe that the radiometric dating methods prove that the earth is 4.5 billion years old.
When the meltwater reaches a lake the heaiest sediments (sand and silt) sink to the bottom quickly and eventually formed thick layers of light colored rock.
Later in the year, by wintertime, the clay has had enough time to settle to the bottom and it forms a thin layer of dark colored rock.
