I always admire those that must say that that radioactive half-lives have changed dramatically in the last few thousand years but have no problem accepting nuclear power which relies on non-changing half-lifes.
Why? Why shouldn't someone accept nuclear power just because they think that radioactive half-lives were different at one time? What matters is what the radioactive materials are doing now. One can still use them based on their current rate of decay.
The nuclear power only relies on the current half-life, not whether they were different at some time in the past.
IIRC, even scientists are now discovering that radioactive decay is not always consistent. IIRC, there was a thread on that not too long ago.
