    Light

    LIGHT.The main sauce of light for our planet is the Sun and yet we are unable to look at it, in other words we cannot see the light direct from the Sun. Nor can we see it indirectly because we can’t see the light from the Sun striking the surface of the Moon even though at night it must be passing by the Earth in order for the moon to shine down on us. What then is really happening? The visible spectrum of light is only visible when the invisible electromagnetic energy from the Sun interacts with the material surface electrons of an object, gas or vapour of some kind. The electrons become excited and act like a transducer, converting and transmitting their own unique characteristics, which in turn expresses a unique form or substance. The electromagnetic radiation from the Sun is invisible otherwise we would not see the object. We see the unique recognizable characteristics of a thing or substance, not because it reflects the Sun’s light but because its surface electrons are energised by the electromagnetic energy from the Sun. It is this information that the eyes and brain process. Of course there are those objects that absorb most of the energy and this we call darkness or black objects.  The characteristics of an object or substance are transmitted in many differing wavelengths and it is these wavelengths and their intensity that conveys its colours, unique form and distance.  Conclusively then light has no velocity and wavelengths of light only have a reactionary time. To say that nothing can exceed the speed of light is something of an enigma because we are visualising the reactionary affect as a velocity and it this secondary effect that enables us to see. Clearly there has to be a medium on which electromagnetic waves are formed which conveyed the signals in the form of light waves without interfering with those signals? My deductions amount to the fact that there is a universal mind/energy on which the excited state, we call light is transmitted or has a reactionary effect. This in the past was called the Aether and should still be recognised, I am convinced that the phenomena we call light, is an excited reactionary effect on this universal energy medium. In principle it is similar to the kinetic energy that can be demonstrated with a Newton's Cradle; normally the wavelength determines the colour of light, whereas in Newton's Cradle the size of the balls determines the wavelength and frequency of the reaction. The intensity of the wavelength or photon of light is however determined by the source generating the luminous electromagnetic excitement and transmitting it in the same way as an aerial mast transmits radio and TV signals.

    The reason for this is because of the intensity of the sun. A photon is considered the  elementary particle responsible for electromagnetic phenomena. It is the carrier of electromagnetic radiation of all wavelengths, including gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves. Visible light is considered to be a portion of the electromagnetic spectrum in the range of about 380 to 750 nm in air. The corresponding wavelengths in water and other media are reduced by a factor equal to the refractive index.

    The refractive index of a medium is a measure for how much the speed of light (or other waves such as sound waves) is reduced inside the medium.

    The reason why you can't see the light of the sun reflecting off the moon directly is because the sun is on the other side of the planet.
