"Radiant matter is simply a re-transmitter of energy from one state to another."

"Wave-Particle Duality helps us to understand the particle and wave nature of light.
Based on the idea that light and all other electromagnetic radiation may be considered a particle or a wave nature, in 1923 physicists Louis De Broglie suggested that the same kind of duality must apply to the matter. He proposed that any particle of matter having momentum (p) Has an associated wavelength (λ)."

"Another consequence of special relativity is that matter and energy are interchangeable via the famous equation E = mc² (in which E stands for energy, m for mass, and c² the speed of light multiplied by itself)."

"the law of vibration, posits that everything (every atom, object, and living thing) is in constant motion, vibrating at a specific frequency."

"It can be kind of hard to wrap our heads around at first, but it’s a scientific fact that everything on this planet and beyond is made up of vibrating particles of energy-. The Law of Vibration states that anything that exists in our universe, whether seen or unseen, consists of pure energy or light and exists as a vibrational frequency or pattern.
Even things that appear solid, like the chair you’re sitting on, are in fact made up of particles which are vibrating against each other, causing resistance, and making it impossible to pass through each other. Your chair is actually pulsating with energy, as is every single other ‘solid’ appearing item that you can see or touch as you look around you right now.
Even the colours you perceive are a vibration of a particular frequency. And sound is nothing more than the vibrations that your brain has translated in order to make sense of it."

"A resonant frequency is the natural vibrating frequency of an object and denoted as ‘f’ with a subscript zero (f0)."
