Geologists often need to know the age of material that they find.
Each isotope is identified with what is called a ‘mass number’.
When ‘parent’ uranium-238 decays, for example, it produces subatomic particles, energy and ‘daughter’ lead-206.
Most directly measure the amount of isotopes in rocks, using a mass spectrometer.
All radiometric dating methods measure isotopes in some way.The late Francis Crick, the co-discoverer of DNA’s structure (along with James Watson and Maurice Wilkins), came to believe that aliens, and not God, were responsible for life on earth.‘There are some, again, who, though they do not suppose that this world is eternal, are of opinion either that this is not the only world, but that there are numberless worlds or that indeed it is the only one, but that it dies, and is born again at fixed intervals, and this times without number.’There is nothing new under the sun.
