What will be the view of the sky and the distances between stars, living on a planet or in a habitat in a super galaxy that has merged with all its nearby galaxies in its cluster, at a time in the ...
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?
This was an idea for a flashback as I pick up my story around 100 trillions years from now at the point where star formation is ceasing and the red dwarf and stellar remnant era begins. Now living ...
I was zooming around on Space Engine and came across the moon of a gas giant that was hovering well above the galactic plane. I'm admittedly not well-versed in under what conditions an Earth-like p...
The advanced civilization in my story is trying to reach as many galaxies as possible in the next few billions years before the expansion of space has sent those galaxies permanently out of reach w...
I am wondering if habitable planets could form around stars in super dense dwarf galaxies. There are some super dense galaxies such as M60-UCD1 and M85-HCC1 which can have a typical distance betwee...
Imagine an Earth-like planet orbiting a Sun-like star in the inner halo of the Milky Way. As a halo star, it will likely be somewhat metal-poor, having formed early in the life of the galaxy, but o...
My character is traveling aboard a spaceship through inter-galactic space (it has left the Milky Way). The ship is traveling at the speed of light or so and has been for the last six thousand years...
I'd like to randomly generate between 1 and 20 million stars for a spiral galaxy resembling our Milky Way. This is of course far fewer than our galaxy (estimated between 150 to 300 billion), but I'...
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...
Is it possible for a planet in our part of the galaxy to have a night without stars? I'm looking for some kind of natural phenomena that would hide the stars, but allow the sun to rise and fall as...
I would like to include a world in a story that is located on the upper plane (or bottom, doesn't matter, but call it upper for the sake of reference) of the galaxy. If you think of the galaxy as ...
Let's say there are billions of asteroids in the galaxy, varying in size from baseballs to hunks of rock almost big enough to be dwarf planets. If someone wanted to set up a habitable location on o...
In my story, reasonably far in the future, an intrepid group of explorers are on the first manned mission to the Andromeda galaxy, travelling close to the speed of light. They slumbered in suspende...
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 ...
Segue 2 is a galaxy with only about 1000 stars and is 111 light years in radius. It has a light output only 900 times that of our sun. (This is a real galaxy in our universe) However, I want my fi...
I'm trying to flesh out the history of a fictional galactic society, specifically the initial settlements and inhabited worlds. Something that I thought would be important to settlers would be an a...
