We are using a Morris-Throne Wormhole Metric. Let's presume the throat of this wormhole (in internal hyperspace) is short, let's say 1km. Now, as you are travelling through the entrance wormhole,...
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...
I have an idea for a faster-than-light spacecraft that I would like to run by the expert minds in this community for a plausibility check. Basically the interstellar ship itself is of unspecified d...
One way of creating artificial gravity is acceleration- gravity by inertial mass. So in theory, if we would find a way to travel interstellar space by accelerating, reaching near light speed, woul...
In my world, interstellar vessels use a drive whose design mankind learned from an extinct elder civilization. While construction of the drives is possible, the physical principles making them work...
I have seen a similar-ish question on here, but it doesn't quite match my inquiry. Suppose you have an interstellar civilization (the means of travel between stars being stable two-way wormholes o...
What would be the most efficient text communication method for a spacecraft operating on a super low bit rate (I'm talking something like 5 bits an hour, excluding error handling)? As you want bo...
I´m building a hard-sifi setting and want to use Stellasers (abbreviation for stellar laser) to provide thrust and power to interstellar vessels. This part one is only concerned with the construct...
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 v...
It is the mid 22nd century A.D. Twenty men and women signed on a ten year space exploration trip to the nearest star system. There are robots to do ship maintenance and a powerful A.I. to monitor t...
2 informational references for Alcubierre fields can be found at the end of this question. Warp-lanes aren't a novelty in science-fiction. Space ships can use a specific route to go through a Gala...
Hypothetical: Hundreds of years into the future. Humanity needs to travel to exoplanets quickly. I'm aiming for hard sci-fi. What kind of propulsion can travel people at 0.1 - 0.9 lightspeed? Is i...
So one of the ideas I've come up with for system to system travel, in the early colony stage of my world, is using fuel boosters to start the journey and then to reach the required speed for the co...
There are many hypothetical systems for bringing spacecraft of the near-future up to speed, some of which may attain some relativity-bending velocities. However, these systems, to achieve such high...
Let's not debate whether is there any friction while traveling inside vacuum space and assume all ships can brave a perfect storm brewing inside the giant molecular cloud. OK let's get down to busi...
I have been recently thinking and writing about a hard sci-fi universe with the exception of FTL. Within the system of Alchiba (or Alpha Corvi) lies a planet under the name of Mannhardt and is an E...
In the near future, say about 50 years, the most powerful governments are starting to compete for control of interstellar resources. The first step is to send a probe or probes to a neighbouring st...
A planet orbiting an Red m-dwarf is tidally locked to its sun. Can it have a satellite which is not tidally locked to the sun? Also can the satellite be tidally locked to the planet ?
So this planet enters our solar system from the 'south' pole at 30 kilometers per second. A bit faster than the first Interstellar asteroid ever discovered. Of course, it plunges into the Sun's ph...
Asked a similar question before but didn't think it through and mangled it. Anyway would it be possible to build a structure between two star systems? Basic scenario is that you have two stars su...
[![enter image description here][5]][5] Model Lightcraft under laser power While sadly the funding for this research has not been forthcoming, there have been proof of principle flights and ope...
Voidcrawler (Mycocelium Nocturnis) is a voracious invasive species, most similar to a fungus but much hardier and with some singularly unique properties: Firstly it absorbs not only light, but als...
I'm working on a science fiction story involving starships travelling about 95% of the speed of light. I wanted to have a reason for the starships to need to shield themselves against time dilation...
Thanks to enhanced space telescopy Earth has found some great candidate star systems for colonisation. But they are not yet ready to try sending people. There's no new physics. However, the cost...
I plan to write a story about a large number of space probes that are equipped with artificial intelligence and told to explore star systems and travel between them. These probes are not equipped w...
A short time ago I read that life might be possible on interstellar planets (i.e. planet-like objects which aren't bound to a star by gravity.) They may be insanely cold on the surface but inside t...
