Question	—	Is it possible to break the sound barrier in space with a really fast spacecraft I was doing some research online about slower-than-light interstellar spacecraft, and it got me thinking about a couple things. Although it may seem empty, the space between stars isn't a perfect vacuum. There's still dust, stellar wind, gas clouds, and many other particles floating around that make ...

Question	—	How would a planetary ring react to a magnetic field? So for the story I'm writing, I'm designing is a gas dwarf with a very strong magnetic field and a planetary ring with a slightly inclined orbit. However, the rocks within the ring are very sensitive to magnetic fields. How would this affect the shape of the ring, if it is able to form at all? They ... (more)	—	about 7 years ago
Question	—	What conditions would an A-type star need to have a blue color? So I'm working on a world that orbits a blue star that's not much bigger (or even smaller) than the sun. I was thinking that an A-type star would be a good choice for it, but it's still is closer to white than blue. Is there any way for the conditions of an A-type star to be just right to give it a b...

Question	—	How far can space time be warped, twisted, and pulled? In the story I'm writing, an ancient civilization once roamed the local group, traveling from galaxy to galaxy with ease. Thousands of millennia after their disappearance, humanity stumbles across the last remaining ruin of their "network across the stars": an inter-dimensional mega structure known s...

Question	—	How big of a tidal wave could 2 binary planets create So I'm working on a story based on a binary system involving two Earth sized, Earth like worlds with very eccentric orbits. In the story, one of the major coastal cities is protected by a massive retractable seawall to protect it from a titanic tidal wave (known as the Leviathan) which occurs as the ...

Question	—	Could this complex star system work in real life? So, I'm working on a story which involves a triple star system that is full of planets. The first two stars, a G type (which is orbited by an asteroid belt and two small rocky worlds) and a B type (with a small rocky world and a super-earth), orbit around a common barycentre. There are also three gas... (more)	—	almost 8 years ago
Question	—	Could a man-made black hole deorbit the moon? 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 (known simply as a rift). Although they're usually stable enough for a ship to travel through, there is one... (more)	—	almost 8 years ago
Question	—	Can this unique planet be colonized? In the story I'm writing, a gas dwarf (named Eden) is discovered in a triple star system. Its atmosphere is mainly oxygen and water based, and its gravity is slightly higher than Earth's. Unlike our gas giants, however, Eden has 2 "surfaces". The upper layer is made up of millions of floating island... (more)	—	almost 8 years ago
Question	—	Could an impact crater make a world habitable? For most of us, meteors are by far the ultimate planet killers. All it takes is one direct hit to suddenly wipe all life from the face of a world. But, rather than taking life away from a planet, what if a meteor impact is the reason that the world is habitable in the first place? In the story I'm w... (more)	—	almost 8 years ago
