I have the feeling all of you are a good bit younger than me. Perhaps I'm wrong about that.
I'm 48 years old. I grew up in Phoenix, a very large city. We could see the stars at night, but in the desert around the Grand Canyon, or at the beach in northern Mexico, south of Phoenix, there were billions of stars.
Many have noticed there are less stars visible now, and I've read discussions about it, but a good answer is not forthcoming.
A couple years ago, I lived for a year in Guatemala in a highland area far removed from any cities, they were all little towns. There should have been billions of stars visible. There were some, but more like when I was in Phoenix from the 70s to the 90s.
I live in a large city in Mexico, nothing even remotely as huge as Mexico City, but it's big. There are only two stars visible every single night. And I can see them from the living room whether the light is on or not.
I've flown many times in my life, and as a kid, the stars were visible from the plane.
Up in the sky like that, crossing enormous expanses of desert and mountain, the sky should have been beautiful. I saw the same two stars I saw from where I live, and a couple more. Not even as many as I saw in Guatemala. Something is wrong.
I just can't buy the cabin lights theory.
