Question Going slower in worlds where fuel is free or insignificantly cheap
Established rules for the universe: FTL travel exists with special drives, special artificial generated wormhole like tunnels where space ships can break the laws of physics. Engines runs hot, burning at max (top 10%, depending on tech) for too long will make the engines overheat. Engines requires ...

Question Mapping the far side of the galaxy
Humans got a one time ticket to the other side of the galaxy, traveling $2r$ in just a few days (where $r$ is the distance from earth to the super massive black hole: 28,000 lightyears) The stars we see are roughly 56,000 years old; now, that's not really that old compared to the grand scheme of thi...

Question Would it be possible to make an inescapable planet?
To start with, i know You measure the Kardashev scale from stellar success, but lets say we have a civilization that are vastly advanced compared to us, so they are equivalent to a type 2 civilization. The question is, could it theoretically be possible to lock an advanced race to a planet beyond te...

Question Generation ship design - Accommodations
What would be required for a generation space ship to give residents the best possible living situation while still using the least amount of space, given the possibilities to have access to common areas. How little space can a person live on for life, and still be sane. Can people use common areas...

Question The effect of a 6 megatonne space ship crashing in to a planet
Follow up question to: How long time would it take for a space hulk to lose orbit? Let's assume that the spaceship crashes into the planet, I used the Impact Calculator to get some result of the crash. Your Inputs: Distance from Impact: 200.00 km ( = 124.00 miles ) Projectile diameter:...

Question How long time would it take for a space hulk to lose orbit?
In the Warhammer 40k universe, there are planets where the population hasn't developed so far and are left in the feudal stage, (or the technology has degenerated so much it is back to the point). Around one of those feudal planets is a Tempest Class Frigate where some mystical (non essential for th...

Question Is it possible for a planet oddly similar to the ones we have orbiting our sun to make a shield to protect an interstellar space ship?
The situation is bad, human kind have waited to the last minute (literally) with building the huge ship that is supposed to save man kind. The sun goes nova, nothing can stop that but the ship has to survive the shock wave. So the idea is the following: if something blows up you hide in the bathtub,...

Question Would it be possible to excavate a planet and mine it without indigenous citizens' knowledge?
There is a more strict version of Prime Directive on a subspace traveling Empire. This empire (without the morale codex of the star trek crew, maybe more like Avatar) would like to get the resources on this planet The resource is sufficient unique and valuable to be worth a lot of trouble. The crew...

Question Is a planet with only vaporized water atmosphere livable?
Is it possible to have a planet where the atmosphere is mostly water vapor instead of mostly N + O2 with solid ground, so not a gas giant? In the sense - how close to the center star(s) should it be for water not to exist in greater bodies of liquid water or in any solid state as a result of water f...

Question Would Hawkings Stellar Drive be possible and would it be effective?
Hawking's radiation emits particles from a black-hole. Lets play with the idea of harnessing a mini black hole in the center of a star-ship. Let alone harnessing the gravity pull to the front and move the emitting particles out the back, (creating a Push-Pull effect). Would the small black-hole be ...

Question Can a planet with 2/3 Orbital eccentricity sustain life?
On a planet where it is Earth-like, the orbit around the sun is a bit longer than 1 Earth year, and the orbit is on 2/3 eccentricity, but where only the "2" part is inside the Goldilocks zone. In winter everything freezes over, at about -200ºC surface temperature. Could animal and plant life susta...
