Ben from UncharteredX has a good video on these drill samples, but does not buy into the mainstream acceptance of how they were made. In fact the granite core samples show continuous grooves and you can calculator the pressure per turn the mechanism was under, and it’s not really able to be done easily.

The core samples do not show continuous grooves, that claim has been thoroughly debunked. With visuals.

You can even see the discontinuity clearly in the linked article

[synecdoche]

A discontinuity being an exception from a great majority of surface consisting of spiralling and continuous lines is no proof, nor debunking.

A spiral form being an exception from a great majority of circular lines may be just that, an exception, and would point towards a non-spiraling cut.

The photo with the discontinuity shows one side only. Therefore there is no way of knowing if and how the lines are connected on the obscured side, and no conclusion can be made either way.

Important to distinguish a spiral cut from a spiral ream. It is entirely possible to chip/drill/chisel a hole, and then to ream it out with a spiral tool.

[synecdoche]

Right. Where may we see the debunking?

[ImPostingOnHN]

In the linked article here, for one.

[synecdoche]

Could someone point to where in the article that is? Figure 5 is not a counterexample in my opinion, for the reasons mentioned in an one of my other comments, namely a single deviation from a spiralling line (if there are such lines) is not proof that all other lines are not spiralling. It is only a counterexample with regards to those particular lines.

[ImPostingOnHN]

They don't need to prove all the lines are not spiraling, only to find counterexamples where the lines (spiraling or not) are discontinuous. One counterexample is enough to disprove a theory. Their explanation of exactly how their theory resulted in the evidence we see is easy to understand. A rebuttal would ideally include a similarly detailed explanation and similar experimentation around how fixed cutting points would have produced the same discontinuities.

Thus, in the interest of scientific advancement, I encourage you to, like here, team up with someone who has no horse in the race, and publish an equal or better rebuttal. After all, science can't advance if we just accept what someone says or limit our disagreement to an internet comment.

It's a pretty old article, maybe an unbiased team already has done this!
