In the final episode of the second season of Cloak and Dagger, Tandy and Tyrone confront Andre in his world (the Dark Dimension, perhaps). They manage to catch him by surprise, and Tandy stabs him through the chest with a sword of light. They then touch him together and enter his mind, forcing hi...
Cartoon with a scene of a hero and villain, which I remember as a screaming, spinning-faces statue thing... I think it was white colored? And a boy, running through a crumbling castle. Would have been early '90s or earlier... not sure about length, but it played on US TV.
It was a vampire movie that I started watching with my dad in the late nineties on HBO; he turned it off because it was too intense for me. I remember it was about vampires being bad and embracing being a vampire. I remember a shoe store scene where they kill everyone. I think the main charact...
The Dark Dimension shows up in Doctor Strange, Runaways, and Cloak and Dagger. Now, when Nico uses the staff, her eyes and the area around them develop a pattern very similar to that of Caecilius and the others who drew power from the Dark Dimension, suggesting that it is the same one. On the oth...
I haven't read the story, but I heard about it multiple times from different sources. The only problem is, I forgot the name of the story and the name of the author, but I think it was Philip K Dick.
So the story goes something like this: in a post-apocalyptic, dystopic world, an artist goes on a...
I recently got this meme:

Since, I keep wondering if Harry Potter is really the only wizard student with glasses or if there are others? Specially since, according to this answer, wizards cannot fix bad eyesight. I've started to watch some clips on YouTube to try find stu...
The recent movie Tenet is based around the idea of "inverting an object's entropy", to make it move backwards in time instead of forwards. A similar thing also happens in Greg Egan's Orthogonal trilogy, set in a fictional universe where
I'm wondering if there are earlier appearances of this idea...
A post apocalyptic horror movie made in the mid to late 2000’s. It’s really really hot outside. It takes place on Earth. It was on Netflix. I remember a car scene so I know they can go outside sometimes.
I am looking for a manga where the main hero is a boy and has two swords at the beginning where one of them at present turns into a woman and via dual cultivation the sword upgrades/gets stronger.

I ran across a short story somewhere around 2005-ish, and now I can't seem to find it again.
The main character is a very wealthy person who firmly believes that God does not exist, and is out to prove it by process of elimination: by demonstrating conclusively that God is not located in any plac...
So I went for a ride this morning. The wind was strong enough (>40km/h) that it was raising a 10+cm chop across just a couple hundred metres of open water; it had also broken up the thin surface ice and pushed it all to the bank I was riding along. And with the waves stirring it, it was clinking and chiming; it made me think of "The Bells of Acheron."
Ares is a greek god and both the comic book giants Marvel and DC have their own versions of Ares. I would like to know that what are the differences between the characters portrayed in both the universes?
I was recently looking at a comic reprinting of Retro Sci Fi Tales # 9, and the synopsis on the site spoke about a story of the "Exposition Universelle", where at a fictitious worlds fair in Paris in 1878, they unveil a "grand inter-galactic telescope so powerful that it can view the surfaces of ...
I recall in high school reading a fantasy novel published in the late '70s/early '80s. It featured a kingdom or citadel on one side of a rift, and on the other side burial sites haunted by demons that sometimes formed armies to attack the humans, especially if the humans ventured across the rift...
The WandaVision TV series takes place in some unknown reality (to me at least having not seen any material outside the show). At the end of the first episode we see that an unknown individual is watching the two through an old CRT screen alongside some more modern devices. A circular symbol with ...
In The Rise Of Skywalker, we see an door opens automatically in front of Rey in order to get the room where Emperor Palpatine presumably hid the wayfinder. Any idea how that door mechanism is still operational and what is powering it even after 31 in-universe years since the station was destroyed...
A space opera novel with a planet whose inhabitants are a group of 'monks' with a quasi-religious monopoly on functional immortality. There's a parasitic/symbiotic plant organism (I don't remember if it was microbial algae or a multicellular parasite or if it was sentient or not) native to said...
@DavidW From the topic guidelines: Questions about artificial satellites whose purpose is not directly related to astronomy. You may ask about their orbit, but not their purpose, usage and safety features. Questions about satellites with an astronomical purpose should be focused on astronomical usage and not broader questions such as the construction of the non-optical components.
So I guess if you want to ask about the physics of how an observation is made, you're golden. Otherwise, probably space exploration.
Ultimately, mods are just arbiters of the rules created by the community. I think most of my reservations are about how difficult it would be to answer it, but then I'm neither an astronomer nor a physicist.
If you just want a theoretical answer, it's possible to compute the required angular resolution (depending how large the target is, how many pixels you want it to cover, and its distance - that's just trig) and from that the required baseline.
A civilization that can build a ringworld or Dyson sphere wouldn't have any trouble just building the telescope straight up. Or if they have gravitics, then who knows what they could do.
