But how do we know that uranium has a half-life of 4.5B years? It is not like we can sit around and wait to see how long it takes for half of it to disappear. Even with a large amount, and waiting for something like 100 years, would it even be noticable?

Nice video, thanks. But how do we know that the half-live of C14 is 5730 years? Radioactivity was discovered on the 19th century, right?

True, but the decay of any radioisotope follows an exponential decay curve as shown at 8:42. So, even if we’ve observed a sample for less than one full half-life, we can measure how much of the parent remains after that time. Then we can extrapolate the rest of the decay curve and determine the radioisotope’s half-life.

Why half life is 5730? Why not something else? Cz the atmosphere around the globe is not the same!

Wouldn't this apply that all carbon atoms should decay into nitrogen
