I am trying to remember an old steampunk novel set in perhaps Victorian times. I only remember a few parts of the novel, but a specific part that stands out to me is that the police/detectives/maybe the upper class have mechanical dogs that they are somehow connected to, like companions but they ...

It seems that planetary or galaxy-scale destruction is a common trope in science-fiction. I'm thinking of things like the halos in Halo or the Dakara weapon in Stargate, able to wipe out all lifeforms in the Galaxy in mere moments. Are there any prior works showing similar technology? I'm mainly ...

Looking for the name of a story about a time traveler who goes back to WW2 England to prevent the development of a cure for cancer. The traveler is a well known cancer patient, who appears at a clinic where a doctor has made a breakthrough discovery that will lead to a cure for cancer. The doctor...

Best estimate was 1978-1980 (just when I was starting school. The male protagonist (teen?) would jump off of a cliff, punch his fists together, and spin forward (spin in a tight curl). To my anglicized ears, it sounded like he said "punchu cheezu" at this point and he transformed into a robot hea...

This was a pair of short stories (published in Analog, maybe late '80s?) set in a near future where man has spread out over the solar system. As for characters, there was a shuttle pilot (female?), and the prototypical absent-minded scientist (male, Scots name). It opens with a discussion of why...

Spacefaring humans meet a race that is almost identical physically. But the aliens have vast mental powers of telekinesis and teleportation, etc. The normal humans are judged deficient and a galactic war ensues. I thought it might be a Philip High story but apparently not. Asimov? Brunner? Rackam...

There was a book I read in middle school about a boy who moves to Europe and moves in with his elders. While there, he finds a stone building in the back; after climbing the wall with one of his friends, he finds dragon eggs. Also, the boy's friend turns out to be a troll who wanted to get the dr...

The movie credits list Paul Dubov as Radek who if you watch the movie is the early-stage mutant who they allow they stay in the house despite strong sentiment that he should be killed. There is also a character played by Jonathan Haze (I believe the last surviving actor from this 65-year-old film...

I'm trying to identify a Young Adult novel I read when I was, well, a young adult, so it must have been around 1970 (though of course it could have been written much earlier). Two friends visit a carnival where one of the sideshows boasts a live dinosaur. It turns out to be the real thing, brough...

From the Development of Spock article on Wikipedia (emphasis by me): However, he was still apprehensive as he wanted to have a serious acting career and did not want to be made to look foolish by playing an alien with pointy ears and other as-then undetermined makeup. When the character was incl...

I'm trying to figure out the name an old anime movie I watched as a child, most likely late 80s - early 90s. It featured a giant robot, which consisted of separate parts with a pilot in each, and they combined to form the complete robot. It sounds kinda like Voltron but I'm pretty sure it wasn't,...

Sadly, as we know, he died, but now the MCU needs a black panther, I have a very good question... Who is going to take the throne now!?

In either the books or the show, are Belters considered legally to be citizens of the UN or the MCRN? They later become their own nation, but it seems unlikely the UN or the MCRN wouldn't try to claim the Belters as citizens, if only because they claim the stations themselves. They also make cons...

What phonemes (or even words in Black Speech) could one distinguish in the below video from 1:26 to 1:29, where Sauron allegedly asked Pippin of who he was?

I read this short story in the 1960s (probably in a magazine), although it might have been a reprint. American or British author. Probably takes place on the Moon, although it might have been an asteroid; almost the entire story is set inside a small airtight tent used by two miners. The MC is an...

Short story probably dates from the 1960s. American or British author. Two men, strangers, are talking in an office; one carries a cane. There is a large, bustling city outside the window. The man with the cane asks the other if he is a human being. The other replies of course he is. Man with the...

I very distinctly recall reading a scifi story as a child, possibly a series of stories. Humans land in a solar system and meet a race of aliens that, if I recall correctly, evolve very quickly, and have a cast based racial split; there are technicians, warriors and so on. The race for some reaso...
