What part of the physical universe is not governed by quantum physics?
Radiometric aging works just fine.
Radiometric dating is no substitute for direct observation, but entails, among other things, the unsubstantiated assumption the decay rate has always been the same. Am I to believe you yourself have applied radiometric dating? I doubt it. And even if/when you did, what was it you were dating? The age of the material, or the age of its form?
Maybe you'd like to settle for radiometric dating and remain satisfied with its answer. Fortunately real science is neither as lazy or dogmatic as you.
One of the dumbest things ever said on these threads -- and that is saying something. ALL OF SCIENCE is based on theories that tie together information, MOST OF WHICH IS INFERRED. We can't directly see neutrons, gravitons, or a lot of things that science tells us about. Do you think string theory or even the red shift were formulated based on DIRECT OBSERVATION? Even the existence of the planet PLUTO was a result of inference.
If you rely on direct observation, you immediately take yourself out of any scientific discussion. As you have this one.

No it doesn't. Please, stop. You are really, really embarrassing yourself with your complete lack of knowledge of the topics at hand. If you want to start a sophomore philosophy thread, go ahead. I am sure the other sophomores and a few of the freshmen will get together and talk about the importance of the phonetics of "Jinandtonix." But it is time for you to quit pestering the grown-ups.
