First time poster here. In a game I play called starsector, some planets use stellar mirrors to raise their sunlight access and surface temperature. AFAIK this has some theoretical basis in actual science. Other planets however have something called a “stellar shade” that does the opposite cooling down the planet by redirecting sunlight away, which I can’t find a basis for anywhere else. Would it be possible to make something like this? Where would it need to be located relative to the planet in question?

Am I hallucinating something? I remember a Jerma long edit, I think one of Cheltie’s, of the horsemen playing monster hunter wilds. I’ve found the vod, but no luck on the long edit. Was it taken down for some reason?
