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,...

Q&A Could habitable planets form in an ultracompact galaxy?

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...

Q&A Feasibility of a black-and-white FTL drive?

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...

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 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 Iron-rich rogue planet that is 12x Earth's mass collides with the Sun; now what?

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...
