Re: Formulas and calculations
How do you know that the plane of the photo is not the fracture? By virtue that we are looking at a photo of a radiohalo, this suggests that the rock was fractured in this very plane. Or are we just taking lucky slices of random rocks???

Re: added comment, Cavediver
Seems pretty clear to me.
Yep, I'm forced to agree

Re: More complete view
Dude, you don’t understand anything!
This seems to be the extent of your rebuttal, and I for one am not impressed. Your inability to understand RAZD's use of two extreme scenarios reveals a worrying ignorance of scientific methods.
Now I am by no means an expert on this subject but I am an (ex)professional physicist and have been following this topic closely. Your criticisms are remarkably hollow and content-free. Without something of more substance from you, I think we can safely say that RAZD has more than successfully made his point regarding the "embryonic" halos and Gentry (and yourself) have been found wanting.

Re: More evidence that radioactive rates have not changed
Given that you think the Sun orbits the Earth in an oscillating helix with a rotary time period of less than 24 hrs, despite a complete lack of causative rationale, why would anyone discuss ANY kind of physics with you?

As you can clearly see here, there are mechanisms that exist that can bot increase and decrease half-lifes of radioactive materials. And for both alpha and beta decay.
Hell, Physics World???, well I'm convinced
Uh-oh, seems these guys weren't...

Tests of nuclear half-lives as a function of the host medium and temperature: Refutation of recent claims

Abstract
When radioactive isotopes that decay by α, β−, β+ and electron-capture transitions are placed in a conducting host material, it has recently been claimed that their half-lives show a significant dependence on temperatureup to a 6% difference between room temperature and 12 K. We have refuted two of these claims by measuring: (1) the β− decay of 198Au in gold, for which we find the half life to be the same within 0.04% between room temperature and 19 K; and (2) the electron-capture decay of 97Ru in ruthenium, for which we find any half-life difference to be <0.1%.
