(I added this video because this is a very good video on tachyons, it explains Tachyons thoroughly and clearly to people who have no idea about what Tachyon is?)
This is a video about Tachyons, physics define it as a particle held to be theoretic, capable of traveling at a speed faster than light.
At the end of the nineteenth century, Nikola Tesla discovered an energy field which he entitled under the name "cosmic energy", in that all the universe is immersed in it.
There are numerous scientists have further developed their research into this field of energy: "Feinberg's Field" or "Tachyonical", so called by the physicist Feinberg who set forth one of his theories in 1966.

Space is not empty, but immersed in a very concentrated energy field, composed of these theoretic particles which move faster than light and which constitutes a source of free energy, situated outside the electromagnetic field, independently of light and of the sun.

It is a primary energy which creates and maintains order in the chaos of matter. When the flux of this energy is shrunk, the organism does not regenerate and disturbances are born and the body deteriorates.

From this is born the need to keep ourselves open to this flux of tachyonic energy.

Tachyonic energy therefore permeates all of creation and all human beings who dwell within it, enabling biological systems to regenerate themselves through the innate ability that they possess to assimilate this vital energy.

The tachyonic field, in essence, constitutes an inexhaustible font of energy which can be used for the benefit of living beings.
