I'm writing creative text and I'm curious to know, just as possibility, can a galaxy by any chance be formed out of a black hole?
Would it be possible for aliens that originated and evolved in a planetary system beyond the ring singularity of a rotating black hole to send individuals out into a normal universe to colonise it?...
Is it possible for a planetary system to form and support life similar to earth-life inside a region of 'timespace' (which is the space within a black-hole), assuming that there is enough space/tim...
For the fluff of my story one of the space-ships is equipped with what I hope is one of the biggest F-you weapons in ship-to-ship combat: a miniature black hole launcher. The launcher fires a whop...
The universe as we know it has ended. The concept of "natural" illumination ended when the last red dwarves and quasars died out. Now, only brown dwarves and blackholes dot the empty void that was ...
The universe described in the orthogonal series http://www.gregegan.net/ORTHOGONAL/00/PM.html is one, in which the minus sign in the space time interval is replaced with a plus sign. So this unive...
I'm writing a sci-fi story, and there is a giant autonomous computer planet that constantly gathers resources from around the universe using drones. It stores a super weapon at the core of the plan...
How could astrophysical jets, emitting matter from black holes be used as energy sources by a space-faring nation? How could they be able to collect and use this form of energy?
In the event of our sun suddenly becoming a black hole or wormhole of sorts. It transports the earth to another solar system similar to ours. Would it be possible for our planet to start circling...
Suppose a species has limitless resources and the ability to construct megastructures of an astronomical scale. Would it be possible, given antigravitational technology (hypothetical), to create a...
I'm trying to build a story around a supermassive black hole, which is ejected from a merger of two galaxies, that is hurtling our own way. What is the smallest realistic distance at which the blac...
In a galaxy far far away... M6760 (I made it up) is an unusually massive neutron star billions of light years away and it is surrounded by a spherical Dyson sphere painted in new improved formula v...
I'm considering a story where an exploration is devised to explore a binary system containing a black hole; the choice is Cygnus X-1, with its companion supergiant star HDE 226868. It would likely ...
I wish to create a world such that it can support the following plot point: the world experiences gravitational waves that are directly noticeable to the human population (i.e. they can feel or see...
Assume that space warfare is dominated by gamma and x-ray lasers (Wakefield-Plasma and Free Electron Lasers) capable of killing targets several light-seconds away. Stealth in space is possible due ...
Black holes are created by the gravitational collapse of massive stars. But in theory, black holes can also be created by any mass at all that is confined within a small enough volume of space, de...
This is based on: Black Hole as a Storage Device What goes into a black hole doesn't come out (except as random electrons or positrons). However, is it possible to store something within the eve...
Suppose someone dropped a black hole into our lovely Sun a few million years ago. It was big enough (far bigger than that) from the start to eat matter faster than radiating it away, and kept growi...
Essentially, my question is, can one larger black hole be split into a system of smaller black holes? I'm assuming energy requirements will be prohibitive, and that it may not be possible without ...
Strange title I know, but you'll understand why quickly. I wanted to use a black hole to create absurd amounts of power for hopefully obvious reasons (kind of useful). The problem with natural lar...
I know that currently, black hole civilizations are only theoretical. But here are my thoughts on why black hole civilizations are impossible. Black Hole Civilization Issues 1. Gravity This is...
I have a civilization that lives on a planet located inside a nebula (and orbiting a normal, sun-like star). Would this nebula somehow interfere with/ obscure the sight of a rogue neutron star/ b...
Is it possible for a planet to be heated and illuminated by a black hole due to Hawking radiation at the same intensity as by a star? What mass and size should a black hole have to produce the sam...
If your ship just got trapped inside the event horizon of an super massive black hole, could the ship "accelerate" back out with an alcubierre drive?
In my story people are traveling from somewhere beyond the opposite side of the galaxy to Earth. The distance traveled is approximately 66 million light-years. I would like the travelers to exper...
Assuming that there is a means of increasing the spin rate of an existing black hole, what would happen to the shape of the event horizon as the spin rate was increased? In extremis what would even...
Cooling in space is a well known difficulty. There are many unpleasant consequences like no stealth in space, difficult space battles which turn into a short wars of attrition (because you have to ...
If it is even possible, what would the Goldilocks zone be like - in fact is such a system even possible of holding life - around a binary black hole? Could it have planets orbiting it? EDIT 1: Oh ...
When traveling at fast speeds through the galaxy, would it be possible to identify where all the black holes were on your path? I know most black holes are identified by their affect on other nearb...
Suppose we detect a stellar black hole passing near the Solar system, and we have technology and time to send a manned mission to study it. Are there any experiments or observations that would hel...
I have been trying to figure out a way of explaining how an advanced society some time in the past built an artificial planet with a black hole at its core and the effects that would have on the pe...
To be very-very simple: The very main setting of my world is a very special and very small galaxy, the galactic core of which is a quasar - with the "iconic" light beam in the middle, serving a sp...
Basic idea: Primordial black hole (2.5% of Sun's mass) directly approaches Sun at fairly rapid pace (300 km/s). Consequently, six days after passing Earth's orbit, it will collide with the Sun; ac...
I wanted two characters unaffected by the heat and gravity to be close to a super massive black hole within the accretion disk, at times moving in orbit and at times completely still. Stars and p...
Following the Schwarzschild metric, we could consider that a white hole=black hole with no angular momentum (no spin?) or electric charge. Would be enough to slow down a black hole and somehow remo...
I wanted to create a scene where two god-like characters are talking or fighting on a planet or fragment of planet to which they've teleported that's about to be obliterated by a black hole. The c...
In the movie Interstellar, Miller's planet is an ocean planet orbiting extremely close to a black hole. The ridiculous tidal effects caused by the black hole cause the planet's water to concentrate...
A black hole is supposed to suck in everything by nature. Micro black holes are theorized to "fizz out", so for example if one was on Earth it would not grow until Earth was consumed. It would seem...
Say you were using a black hole as a propulsion drive á la Crane and Westmoreland http://arxiv.org/pdf/0908.1803.pdf- so your black hole has a radius of around .9 attometers - super tiny - around ...
Assuming we are unable to see the black hole via any way such as gravitational lensing, accretion disc or whatever. This is hand wave approach just to make my setting work, due to this answer whic...
Is it possible for there to be a "solar system" of sorts with a black hole and a few suns orbiting around it? Could that system be stable and (if so) would it be possible for some civilization(s) ...
Assuming that the only fancy available technology is FTL drives (to get there) plus anything needed to protect and sustain a crew during the journey from Earth to Sagittarius A (whether it takes a ...
Okay, so our society has starting harnessing significant amounts of energy from its sun, and has started mass producing micro-black holes (although there have been experiments with gathering energy...
Context: So assume there are an unknown number of near-omnipotent/omniscient beings who have been confirmed to live inside of an area of space called the Active Galactic Nucleus (AGN). To provide ...
Say you have a galaxy, possibly ours, with a central black hole. In an instant the black hole falls through a plot hole and vanishes. What happens to the rest of the galaxy? Does everything keep ...
Consider the facts that a blackhole: Eats everything that passes through its event horizon. In layman's terms, it is defined as the shell of "points of no return", i.e., the boundary at which...
Within the Star Wars Extended Universe, there is a science base on a small object within a near impenetrable sphere of Black Holes. Is this possible? The place referenced is called the Maw Install...
Useless Backstory "Why are you waking me up Sergeant? And why did we enter near-light speed?" "We received a distress call, and there wasn't enough time to notify you, sir." "What kind of distress...
Humans developed a new weapon: Black hole launcher. How it works: A mobile particle acelerator acelerates two particles to huge speeds and collide both. A mini black hole is created. The mini b...
A civilization creates a supermassive black hole with an electric charge such that the radius of its inner horizon is 3/4 the radius of its outer horizon. In nature, a black hole with this much el...
