I grew up in a rural place where we could see the texture of the milky way just stepping outside at night—it’s been fun taking friends who grew up in cities on wilderness backpacking trips and sitting out to watch the stars. There’s an awe to a true night sky that I think has real psychological impact.
I did also have a cool experience, deep in the backcountry at a high elevation camp some years ago: we went to sleep in a gale, the tent flapping all around, with a cloudy sky. I thought we’d get a big storm, but I woke up hot at 3am, the air totally still. I slid out of the tent and the sky was completely crystal clear. An incredible spread of stars. I watched for a while and noticed a reddish glow on the horizon. We were so far out and it wrapped around in all directions, so I knew it couldn’t possibly have been a town, but I was puzzled. I learned about airglow when we got out of the woods: <a href="https://en.wikipedia.org/wiki/Airglow" rel="nofollow">https://en.wikipedia.org/wiki/Airglow
Outside of a few places like the Himalayas or Australia isn't not possible to see the darkness everyone lived in until street lighting.
This is the most accurate map and it still under reports light pollution under 21.5sqm <a href="https://www.darkskysites.com/" rel="nofollow">https://www.darkskysites.com/
Worse satellite constilations may make it impossible to have a dark sky anywhere: <a href="https://arxiv.org/html/2604.09427v1" rel="nofollow">https://arxiv.org/html/2604.09427v1
Led lights have caused such a massive increase in light pollution, let alone the effects on humans due to the blue spike, that they should be banned outright.
Yeah I really don't like the proliferation of blue-pumped LEDs, they're environmentally friendly from the narrow perspective of energy use but they make the lived environment much worse in other ways, particularly the horrid clinical high-K ones people who want to make a 'modern' ambiance love so much.
In my view we should simply have improved on what already existed, instead of blue-pumped LEDs we should have used monochromatic amber ones like the SOX streetlights which were once ubiquitous in the UK. Night actually looked like night back then, rather than a cheap and nasty approximation of daytime.
It's so interesting that people assume the color of sodium lamps is the color of night just because that's the color technology made it at one brief moment in time. Just goes to show that illumination is culture, just like everything else
