The Speed of Light is an illusion.
Light has no speed.
Light is the Motion of Energy.
The motion of energy is constant.
It is the wavelength, frequency and vibration of energy that is variable.
The motion of matter relative to energy (Space) is always constant, consistent and continuous.
It is the momentum of matter relative to matter that is variable.
Energy is expansive and in continuous motion.
It is infinite, eternal and continuous.
Because Energy is Absolute and relative to nothing, it has no speed.
It has stillness & depth.
It is not light that is speeding through space but space & time that are in motion relative to our Self.
That motion is always constant.
It is our Self relative to that motion that creates the illusion of the Speed of Light.
