Phir, maine uski shamiz ke upar se hi uske mamme dabane chalu kar diye or use kamare me le gaya or bistar par patak diya. Kam se kam 5 minute tak, main uske hotho ka chumban karta raha or phir uske ek mamme ko chusne laga. Ek haath se, main uske dusre mamme ko daba raha tha. Phir maine kuch der ke baad, maine uski salwaar bhi utaar di.

The method compares the amount of a naturally occurring radioactive isotope and its decay products, in samples. It is the main way to learn the age of rocks and other geological features, including the age of the Earth itself.It may be used to date a wide range of natural and man-made materials.The object's approximate age can then be figured out using the known rate of decay of the isotope.For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms.Carbon, uranium and potassium are just a few examples of elements used in radioactive dating.Each element is made up of atoms, and within each atom is a central particle called a nucleus. It’s important that we allow God’s written record of history, the Bible, to guide our thinking about the past—this includes our understanding of the age of the Earth/universe How many times have you heard something like, “This animal lived 50,000 years ago”, or “This person died 20,000 years ago’?Have you ever wondered how the scientists knew the age of the bone?

For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products (in this case strontium).If one knows how much of this radioactive material was present initially in the object (by determining how much of the material has decayed), and one knows the half-life of the material, one can deduce the age of the object.Radiometric dating (often called radioactive dating) is a way to find out how old something is.Radioactive dating uses the ratios of isotopes and their specific decay products to determine the ages of rocks, fossils and other substances.Elements occur naturally in the earth, and they can tell us a lot about our Earth's past.Those who don’t accept the Biblical account of history look for other ways to discover the age of things.
