In another forum, we were discussing the subtle elements and their relationship with senses.
Sound is associated with Space
Touch with Air (gas, motion)
Sight with Fire (light, heat, color)
Taste with Water (liquid)
Smell with Earth (solid)
The speed of light however is much faster than the speed of sound, even though light is denser and more expressed than pure sound (vibration). Light has a particle and wave character whereas sound is simply wave. It’s speed is dependent on the medium of vibration.
Physical sound moves as a wave of compression/ decompression through the medium of air, a gas. The actual speed potential of sound through ether/space is quite a bit faster than the speed of light.
Something interesting to consider.
