They used to be prettier.
Seven is ‘Completion”
After millions of years they are all harridans. So sad.
“They used to be prettier.”
Here’s the thing. The clear night sky background is black to the our eyes. And you can be standing in a quiet place and hear no sound.
But, if a very sensitive microphone and amp is brought to that quiet place, you’ll hear all sorts of noises.
Similarly, if you amplify that night-sky background sufficiently, it will pick up light you can’t see. You could call it light noise.
Personally, my night sky is black and my quiet places are quiet. Our eyes see what they need to see and our ears hear what they need to hear.
