Why Blue Sky?
The physics of why we see a blue sky is an interesting topic in its own right, but the blue sky can also be likened to our physical connection to one another as well as being a metaphor for the spiritual unity we experience through that connection. First, let’s briefly look at the physics of the blue sky: Without the atmosphere that surrounds our planet, the sky would appear to us as (just as astronauts see it in space) all black with the tiny white dots of the stars and, during the daylight hours, the light from the sun just a larger white spot in the blackness. Instead, the interaction between the light from the sun and molecules in our atmosphere gives us the big, beautiful canopy of blue sky beneath which we live our daily lives. To see how this happens, we need to back up a bit… the universe is made up of particles, many of which have a type of energy associated with them that we call electric charge. Any time a charged particle vibrates in space, it gives off electromagnetic radi
