story identification - Book where human thoughts are affecting the universe

Basically our thoughts are ruining everything. Like when humans are taught stars are giant balls of gas. To the rest of the universe they aren't but humans think it and destroy alien planets. I think they come to seal us off from the rest of the universe.

Quarantine by Greg Egan, which was also the answer to this old question and this one and this one and this one. Any of these covers look familiar? From the Wikipedia plot summary:

The novel is set in the near future (2034–2080), after the solar system has been surrounded by an impenetrable shield (constructed by either aliens or extra-solar humans) known as the Bubble. The Bubble permits no light to enter the solar system, and as a consequence the stars can no longer be seen. This seems to be mere background at first, but in fact it is central to the plot.
In the novel a physical process in the human brain is responsible for collapsing quantum wavefunctions representing systems into particular eigenstates. Human observations of the universe were reducing its diversity and potentiality (for instance, by rendering it uninhabitable to beings that relied on stars being something other than the enormous nuclear fusion-powered furnaces human astronomers have observed them to be). Hence it is suggested that the Bubble was constructed to prevent humanity from wreaking massive destruction on the rest of the universe through the process of mere observation.

story identification - Animation: floating island, flying pests

At least 20 years ago I watched a short animated film which stuck in my mind. The whole thing was wordless, possibly European, and I'm pretty sure I didn't imagine it... It featured a flying island which was inhabited by some creatures who (in my memory) reminded me of the Moomins. The island was frequently bothered by large winged animals who swooped around, although I don't think they did any actual damage. At the end one of the moomin creatures suddenly gets a weird feeling, feels forced to climb to the top of the island and then plunges down a shaft right through the centre - only to emerge at the bottom as one of the flyers. Answer Skywhales from 1983. The story begins with a man warning the tribe of approaching skywhales. The drummers then warn everybody of the hunt as everyone get prepared to set "sail". Except one man is found in his home sleeping as the noise wake him up. He then gets ready and is about to take his weapon as he hesitates then decides ...

harry potter - Did Dolores Umbridge Have Any Association with Voldemort (or Death Eaters) before His Return?

I noticed that Dolores Umbridge was born during the first Wizarding War, so it's very likely she wasn't a Death Eater then (but she is pretty evil -- who knows?). After that Voldemort was not around in a way that could affect many people, and most wouldn't know he was planning to rise again. During that time, and up through Voldemort's return (in Goblet of Fire ), did Umbridge have any connection with the Death Eaters or with Voldemort? Was she doing what she did on her own, or was it because of an association with Voldemort or his allies? Answer Dolores Umbridge was definitely not a good person. However, as Sirius points out, "the world isn't split into good people and Death Eaters". Remember that he also says that he doesn't believe Umbridge to be a Death Eater, but that she's evil enough (or something like that). I think there are two strong reasons to believe that: Umbridge was proud to do everything according to the law, except when she trie...

tolkiens legendarium - Did Gandalf wear his Ring of Power throughout the trilogy?

After Gandalf discovered that Sauron was back and sent Frodo on his quest to Rivendell, did he continue to wear Narya (one of the Three Rings)? It seems like a huge risk to continue to wear it after the Nazgûl (Ringwraiths) started to try and reclaim the One Ring; if they managed to get the ring to Sauron, couldn't he be corrupted by his power? Whatever powers Narya bestows upon him couldn't possibly be worth the huge risk, could it? Answer When Sauron forged the one ring and put it on his finger, the other ring bearers were immediately aware of him and his intentions and removed their own rings. There is no reason why they couldn't merely do so again. As soon as Sauron set the One Ring upon his finger they were aware of him; and they knew him, and preceived that he would be master of them, and of all they wrought. Then in anger and fear they took off their rings. "Of the Rings of Power and the Third Age," Silmarillion

star wars - Why don't rebels take Stormtroopers' armor?

Admittedly, the armor of the stormtroopers is not the best, but it's better than nothing. Why don't the rebels strip the armor from dead stormtroopers to use with their best soldiers? I'd really like to understand why they don't do this.
