Science-Fiction has tools to destroy anything: atoms, molecules, DNA, cellular organisms, multicellular organisms, buildings, streets, cities, countries, continents, planets, and even stars. Some e...
The Rygyphae are a species that lives in the geothermal pockets, areas heated by volcanic activity. The rest of the planet is nothing but frozen ice and rock, but these pockets are lush jungles ful...
In my world, people have powers based on the four fundamental forces. One of my characters can generate spontaneous gravity to crush his opponents. He's also resistant to his own power (so I ignor...
In my story, set in the far(ish) future, humanity discovers a way to extract energy from black holes (perhaps via the Penrose process?), which sparks conflict as various factions attempt to take co...
Imagine a civilization developing on Planet X that is orbiting a black hole (or a similar gravitationally massive object). Given the time dilation near such a massive object, do the inhabitants of ...
Imagine a planet - henceforth Planet X - that is orbiting very close to a black hole. The space-time distortion will be very high there and according to the theory of relativity, the time there wil...
The relationship between the distance, $d$, of the event horizon from a black hole's center and the tidal acceleration, $a$, experienced by an object near a black hole allows for scenarios in which...
In my universe, humanity has learned how to open wormholes for transportation, how they are opened is irrelevant and can be hand-waved, what must be kept in mind is that when they are opened, two e...
The Background: It's the year 4000 (or whatever), and mankind has cheated FTL travel. As a result of this 'cheating' rather than solving, however, they can't easily go beyond their borders. Howe...
I wish to clarify my doubts regarding time dilation Is it possible for a planet to be habitable like Edmund's planet from interstellar, which has somewhat similar gravitational force as Earth (9....
If an FTL experiment created a black hole or keugleblitz within 100 au or less of our sun, what would it's post creation statistics have to be to consume the majority of our solar system within 10 ...
I recently watched this Kurzgesagt video exploring the question of what would happen if you had a black hole the size of a coin. To summarize the video: A black hole with the MASS of a coin wo...
To add to my previous question. Can a black hole be a wormhole or can a wormhole exist within a black hole? The result I want to get is this: You enter a black hole in one part of space and exit ...
Two days ago I asked how we can detect a (really) small black hole. The best answer (to me) was "gamma rays". Since this black hole is relatively close to our planet (a few AUs), this could be a pr...
Apparently it is theoretically possible for a planet to achieve a stable orbit around the singularity at the centre of a black hole within the event horizon. This means that life could hypothetical...
So I want a large power source to heat my new real estate on the Jovian moons. I create a micro black hole (MBH), maybe a few kg, maybe more and drop it into Jupiter. I expect the following to h...
This is set in the same universe as my Andromeda galactic war question (same tech level). In this question, I had somewhat purposely labelled the galactic core as "off-limits" (black holes and oth...
A ship powered by a black hole of a few hundred thousand tons (say, under $6 \times10^8$ kg, which would have a lifetime of several years and a power output of a few hundred petawatts) crashes (mal...
Imagine a pair of black holes in orbit around each other. I'm wondering how this would distort their mutual event horizons. In fact would it be possible to "break" the event horizons by reducing th...
Using the process of 'pair production' and using the nature of a blackhole to separate and destroy one of the particles from that pair, would surrounding blackholes with heavy metals (which increas...
I am trying to understand the physics of an interstellar race. Say two ships are racing past a black hole as if it were a corner on a race track. One of the ships takes a hard line and comes very ...
Let us assume we have a Kerr metric (rotating) black hole of 10 Sol-masses, spinning at 300 revs/s (as measured by a rest frame observer). What yield strength (assume that yield strength is limiti...
How do you cut through an unbreakable armor? With an all-powerful sword, of course. No really, if we had seemingly unbreakable matter (lets give it the original name of Unobtadamentium, or Uium for...
The most common explanation of what would happen to a space-ship that falls into a black hole ends with spaghettification. However imagine there was a space-ship built out of unobtanium, that cou...
If a race were advanced enough to colonise space and travel between galaxies, would it be possible for them to harness a black hole in some way to generate power for the massive ships needed to col...
Could a kugelblitz be stored in a container lined with metamaterials to reflect back the outpouring of hawking radiation or would it require something more exotic? Could it be pinned in the center ...
Could you power a starship by feeding matter into a black hole and collecting the plasma produced by the tidal forces ripping apart whatever you fed it, or is this impossible/impractical? I keep re...
A person is traveling in a space craft that was designed and built by sufficiently advanced aliens. This space craft left from Earth and is capable of traveling infinitely close to the speed of lig...
What would happen to to a planet 10 times the size of Jupiter, if there was a black hole the size of a golf ball in the core of the planet? Would the planet be eaten by the black hole? Or would t...
I'm writing a science fiction, although I'm not from a physics background. A part of my plot is: In a futuristic Earth threatened by huge power demand and climate change, a scientist creates a qua...
I was wondering if a small black hole would make a feasible/possible propulsion source, and if so, how. Pros Black holes release Hawking radiation, would should be easy to direct in a certain ...
Okay so we all know that one planet from the movie "Interstellar" that orbited the black hole Gargantua. How do I NOT get that? What's the minimum safe distance for a planet to be from a black hole...
My idea is to have a place that is "inescapable" by any conventional propulsion system, except it has Earth-like conditions: a breathable atmosphere, 1.0g gravity, etc. What would have to be the c...
In the story I'm writing, humanity has cracked FTL travel by compressing a chunk of matter outside the craft into a short lived, gravitationally weak black hole that leads to a higher dimension (kn...
Recently LIGO discovered gravitational waves caused by two black holes that were orbiting each other, and then collapsed into one black hole. A few months later, we find out that this actually happ...
If Earth would have been sucked into black hole. Would it be crushed by gravity pressure or not?
As I understand it, very small black holes have very small and close event horizons, and wouldn't necessarily pose a gravitational risk (I know they give off huge amounts of energy, but let's leave...
In many Science Fiction books and games, there are worlds or planet-like objects that are rings that orbit (or float around in space) (some examples being the Halo (from Halo) or the Ringworld (fro...
So your star and/or planet gets hit by the CrushSun. The huge laser looks terrifying, but then you realize that the main weapon is the microblack hole it hit you with. What does it look like when ...
The story begins in classic disaster film style. A small rogue black hole is approaching our Solar System. It isn't going to get close enough to destroy everything, but it will agitate our Sun, ca...
What immediate effects would a small, short-term black hole have if it appeared in a residential backyard? How small or short-lived would it have to be to be survivable, if it is survivable at all?...
So the premise goes: A previously-traversable wormhole evolves into a black hole because (x) happens. What's (x)? What would it take for this to occur? Either naturally (a cosmic occurrence), by ...
For my story to work, my characters have to stumble across a small wormhole that actually exists on Earth and is responsible for multiple disappearances throughout history. It connects a point on E...
An x-ray binary is a binary star system consisting of a star and a stellar remnant. As matter is ripped from the star and is then accelerated into the neutron star/black hole by its gravity, x-ray...
Note: I am aware of a previous question Physiological effects of living on a world close to a black hole As I understand it, that question refers specifically to a planet that is in a non-ideal ...
Imagine aliens dropped a small black hole (say, 1% of the moon's mass, so you wouldn't notice the difference in gravitation) into the sun (from the far side of the sun, so nobody on earth can see i...
Suppose it was possible to travel to inside the event horizon of a black hole safely. Also suppose said black hole is large enough that the curvature of the horizon of the surface of the central ma...
Let's say you were living on a planet near (but not too near) a black hole. I'm thinking of the planet Miller in the movie Interstellar. Obviously there are some strong tidal forces. But at this d...
