Greg pittsburgh dating
This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14. She called him and then texted him once afterwards and NEVER heard back.
Maybe everyone just felt bad for us OR maybe they wanted to win the Ju Ju Smith-Schuster signed shirt?
She met Greg online this past November and really got to know him well.
She didn’t meet him until February for the first time for their first date in the South Hills.
So, if we find the remains of a dead creature whose C-12 to C-14 ratio is half of what it's supposed to be (that is, one C-14 atom for every two trillion C-12 atoms instead of one in every trillion) we can assume the creature has been dead for about 5,730 years (since half of the radiocarbon is missing, it takes about 5,730 years for half of it to decay back into nitrogen).
If the ratio is a quarter of what it should be (one in every four trillion) we can assume the creature has been dead for 11,460 year (two half-lives).
