We’re forgetting what darkness feels like

    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:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Airglow" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Airglow

      Outside of a few places like the Himalayas or Australia isn&#x27;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:&#x2F;&#x2F;www.darkskysites.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.darkskysites.com&#x2F;

      Worse satellite constilations may make it impossible to have a dark sky anywhere: <a href="https:&#x2F;&#x2F;arxiv.org&#x2F;html&#x2F;2604.09427v1" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;html&#x2F;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.

        I&#x27;ve driven across Australia a couple of times. Night on the Nullarbor is an amazing experience. So. Many. Stars.

        I was lucky enough to witness a thunderstorm over the desert, too. Too far for any noise to reach me, I just saw the clouds lighting up on the horizon. Incredibly beautiful, and not a little spooky. I totally understand why there are so many UFO sightings there.
