Sorry, that's not how it works. Any sample from your tree should
the same percentage of carbon-14. If it didn't, then that would be a
major blow to the reasoning behind the process.
You could still make your point using trees, if the data
premise - in some areas the tree ring record is complete and detailed
enough that an artifact made of wood can be dated by comparing the grain
in it with the ring record for the area (dendrochronology). Now, use
carbon-14 dating on the same piece. If the dates given by it are
divergent, outside the margin of error of the tests, you would be
showing that there is a flaw in the system.
Indeed, this has been done, and a correction scale exists,
adjustment for the small difference between the real age of items, and
the apparent age given by carbon-14 dating.
For more information, a couple of semi-randomly chosen websites
When visiting the latter, I especially direct you to the
Corrections, Calibration, and K-12 (pages for kids usually have very
useful and easy to follow explanations).
I haven't found a simple site explaining the problems with your
hypothesis that half-life might vary over time. The best I can point you
and suggest you check out their reference, given at the bottom
article. Incidentally, I'll note that the concept of radioactive decay
is considered a law of physics, so it's rather well accepted as
accurately describing the actual behavior of radioactive particles.
Finally, no ridicule was intended, but we're in the realm of
not some courtroom in California where you can introduce any hypothesis
you want, and expect the Prosecution to waste their time trying to
disprove it rather than make their own case. You want to argue that a
natural law isn't valid, that's fine, but don't expect others to jump
through a lot of hoops trying to debate with you.
It is our attitude toward free thought and free expression that will
determine our fate. There must be no limit on the range of temperate
discussion, no limits on thought. No subject must be taboo. No censor
must preside at our assemblies.
