I'm back
The scans are useless since what you're suggesting has no correlation . You just said the golden spin is dedicated to making things spin forever, yet fail to provide any instance where a character has actually said that.
Even after explaining the golden spiral's relation to energy and infinity, you ignore it and simply refute with what I can only describe as brick wall ignorance.
The Zepelli family has always strived to achieve the idea of infinity for the purpose of medicine and executio. What is this
idea of infinity they are striving for? Let's look at context.
The way to achieve this "infinity" is through the golden rectangle / golden spiral /
infinite scale (as it is referred to once while showing a diagram of the golden spin/rectangles below it). By spinning bullets in the golden ratio, it creates the golden spin. The golden spin is directly described as an endless rotation, twice. First in
this scan, calling the golden spin a "spiral that continues forever"and second in
this scan where it is stated that within the golden rectangles is a rotation that continues infinitely, clearly referring to that same golden spi . Note, this is a clear use of the word "infinite" to describe something that goes on forever.
Gyro outright tells Johnny that
he needs to spin his nails in the golden spi (a spiral that continues forever) and
that the only way to achieve the golden rotation is to use the golden rectangles (and obviously the endless spiral they create).
Johnny later afirms that the only way to create infinite rotation is with the golden rectangle and the spiral pattern within it.
From this, it is a reasonable assumption that if you spin something in the pattern of a spiral that continues endlessly, then whatever you are spinning is also going to continue endlessly. Which all matches up with what we see of the infinite rotation's effects.
Valentine freaks out about how long it's lasting and
fears he's going to be buried alive by the spinning effect for eternity.
These scans are essentially every explanation we get on the infinite rotation and the golden spin. Is there anything in there about being able to hit things with force equivalent to infinite joules? No. Because that is not the purpose of the spin.
There is exactly one scan that states the bullets hold infinite energy.
This description of Tusk 4. States there is "infinite rotational energy", and that the "damage is likely endless". However, Shiro gave the direct translation of the original japanese a while back, and it is:
The spin created from horse and Johnny created infinite amount of rotational energy. It manipulates gravity, breaking dimensional barriers in the process (capable of lasting indefinitely)
Nothing about endless damage, so let's throw that away if we hadn't already. Second, "infinite amount of rotational energy". Given the previous scans I've provided however, we can use context to show what "infinity" is actually defined as in Part 7. "Infinite rotation" is always directly linked to the golden spin. The power of infinity that the Zeppelis strive for is achievable only through spinning their steel balls in the the pattern of the golden spin, a spiral that continues forever. The spin within the golden rectangles that Johnny and Gyro use is directly referred to as "a rotation that continues
infinitely", clearly using the word to describe something that continues forever. From this, it is clear that Part 7 defines "infinity" as "something that lasts forever" rather than "something within infinite power". And despite what PL would have you believe, this does not make the explanation redundant, it makes it a clarification and further supporting evidence on what it actually means to be "infinite" in Part 7.
