Hi Invincible,
they do differ from tachyon....frequency-based vs. non-frequency....
I think of the other pendants as "giving" you a certain frequency....whereas tachyon is just pure potential, an antenna if you will, for YOU(Higher Self) to determine what to convert for yourself from the raw potential. Your body's own wisdom decides what frequency it needs, rather than being supplied by a specific frequency-based tool.
Here's a blurb from the tachyon website...
Tachyon Energy is the source of all "energetic" manifestation. Technically, according to physics, Tachyons are a pre-energy, neither positive, negative, or neutral; energy being the ability to "force" matter through space, according to the dictionary.
Tachyons exist only above light-speed and do not exhibit a gravitational force. They do not impose influence on anything, but only offer the potential to be translated into any frequency, or energetic requirements.
They are the first condensation from the Zero Point Field of all potential. Their only purpose is to assist and maintain all manifest form in it's relation to it's potential source.
There are many, many frequency based energies accessible, with phenomenal variables, at so many levels, for example, the "Tesla inspired" Purple Plates are likely one of them. They are based out of aluminum, and we already know that aluminum is not a very substantial antenna for the Tachyon Field after the proprietary 14-day process of sub-molecular restructuring known as TachyonizationTM. [along with most other metals] Tachyons do not exhibit a vibration, and the highlite of the Purple Plate experience is it's positive vibration, or so it seems.
There are so many people calling so many things "Universal Life Force Energy" out there these days. In one sense everything does have a universal connection to the same potential source, but there is not one frequency or vibration that has the capacity to enhance all others.
This is where "resonance" comes in. Each and every vibratory influence may or may not exhibit compatible resonance with other such manifestations. There is also the possibility of incompatible "dissonance" between each and every vibration etc.,
Certain frequencies have very large capacities or ranges of possible resonance, but will still fall short after certain ranges, which means they may act favorably on many things but still may act unfavorably on other things. Another limitation of frequencies is that they may seem good at first but neutralize or become adverse over time, which brings us to the term "coherency". True coherency is interactive & ongoing in it's meaning. In other words energies that help us partially, or temporarily are not truly coherent.
The culmination of all of the cutting edge Quantum physics research of today has for it's focus, the "Unified Field theories. At present there is not one theory of "each and every thing connected to all things" that is verifiable.
The Physics of Tachyons are verifiable at a base level and hold the promise of a possible key for the empirisists of the day in completing such theories.
We are answering this particular question in depth in this way to let everyone know that ATTI and the International Tachyon Institute are representing the actual Tachyon Field as it has been theorized for decades and now preliminarily understood in physics.
The Tesla Purple Plates have an apparently wonderful vibration, but have no verifiable direct relationship with the promotion of true coherency throughout the whole range of frequency manifestation. TachyonizedTM materials have consistently been shown to support the coherency of whatever frequency variables independent laboratories have chosen, and have not been verified to exhibit a measurable frequency themselves, other than the host material.
