Light is weightless. It is energy, not matter.

Light is wavy space that travels at an average speed of 186,282 miles in 
a second.

Light vibrates back and forth at different rates, from slow-moving low 
frequencies to extremely fast, high-energy gamma rays, depending on the 
source that produces them.

The vibrations of light, known as photons, are the result of alternating 
degrees of resistance and conductivity of space.

The range of frequencies that light can produce represents the entire 
spectrum of electromagnetic energy.
