Q&A Would would occur if a person travelled from a wormhole in flat empty space, to one on Earth?

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,...

Rigorous Science Solving the biggest problem of relativistic interstellar spacecrafts

In FTL-free universes, interstellar travel is often done by vessels capable of continuous acceleration (the drives themselves are often magitech), which can use the effects of relativistic time dil...

Q&A Would there be artificial gravity on a spaceship that undergoes constant acceleration?

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...

Q&A How would a physicist explain this starship engine?

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...

Q&A Stellaser Part I: Trial by stellar Fire or The best design out of three for a solar powered 5 Petawatt laser?

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...

Q&A 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 v...

Q&A How do I explain that an interstellar spaceship still requires risky spacewalks?

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...
