Lol, garbage, because it degrades your extremist-like faith in evolution.
Evolution not only doesn't need faith, knowledge of it only grows via skepticism, which is encouraged.
All of them, not just carbon.
Well, you certainly cannot prove that radioactive isotopes decay at the same rates over time. You cannot say with any certainty that Uranium isotopes decay at the same rate today as they did 2 billion years ago. You just can't do it. It is impossible for you to know that. It is impossible for anyone to know it. You can't even say they decay today at the same rate they did 10 thousand years ago.
Gamma ray measurements from the supernova SN 1987A demonstrate that the half-life of radionuclides did not differ significantly at the time of the supernova from what they are today:Well, you certainly cannot prove that radioactive isotopes decay at the same rates over time.

Constraints on stellar yields and SNe from gamma-ray line observations said:The explosion of SN 1987A in the Large Magellanic Cloud was a great opportunity for gamma-ray line astronomy. For the first time, a supernova explosion occurred close enough to be in reach of available gamma-ray telescopes. During core collapse, substantial amounts of 56Ni and 57Ni are produced which subsequently decay under gamma-ray lines emission to 56,57Co and finally to 56,57Fe (cf. Table 1). The production of these isotopes in supernova explosions has been indirectly inferred from lightcurve characteristics, reflecting the respective decay times. The direct observation of gamma-ray lines from 56Co [23] and 57Co [19] in SN 1987A was a brilliant confirmation of this interpretation.

Great, so you agree with me. How brave of you.
Your disillusionments are not my concern.
All of this is barefaced lies.
I am constantly amazed by the destructive effect of religion on human morality.

Haha, are you sure you took chemistry?
It's impossible to know anything was absolute certainty. That doesn't mean you've presented any plausible or useful suggestion as to how or why anything in the universe is occurring, while scientists do a pretty damn good job utilizing half-lives of objects for all sorts of purposes.
Considering you don't even consider universally accepted principles about atoms, I can't really see how a discussion about how the Sun came before the Earth could ever even move forward.
I guess the whole world will have to keep looking at all these lies perpetuated by public universities across our country, like:
Radioactive decay - Wikipedia, the free encyclopedia
Ionizing radiation - Wikipedia, the free encyclopedia
Have a good one.
I don't even need to comment here. I'll just embolden the problems with what you have just said.
That just isn't true. I have no faith in the evidence. I have trust in the people who explain it. I can see the evidence for myself.For most people, it takes a great deal of faith to believe that evidence. I know it's hard to understand, but until you do, just have faith that it's true.
All of the radioactive elements decay. They decay at know set rates that can be used to cross calibrate each other and that agree with outside data-sets, such as tree ring data and magnetic pole reversal data when it is available. If you CHOOSE to IGNORE these facts, knock yourself out, but please stop pretending that there is a rational reason like, " You can't even say they decay today at the same rate they did 10 thousand years ago." I sure as hell can say that and it has been demonstrate using both outside data-sets and other elements, so get over it and find another hobby horse.
Gamma ray measurements from the supernova SN 1987A demonstrate that the half-life of radionuclides did not differ significantly at the time of the supernova from what they are today:
Given that SN 1987A occurred 168,000 light-years away, we know that the rate of radioactive decay has been fairly constant for about 168,000 years (the metric expansion of the Universe is not a significant factor for an object that close to us, so the 1 light-year away = 1 year ago standard is pretty accurate here).
I've read that the same has been confirmed of a supernova detected ~60 million light-years away, but I am not well-versed enough in the literature to confirm it at this point in time.
If you can't confirm it, and I can't confirm it, how can we conclude that it is true?
