Q&A What phenomenon (gravitational?) in space would allow the transfer of humans rapidly between two planets or system-wide?

So what I'm looking for is some plausible idea of two human planets, orbiting each other closely, that despite having regressed to a medieval homage, were capable in this old era of powering solar ...

Q&A Potential system to system travel?

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...

Q&A Would this design be useful for surviving relativistic impacts?

Let's say that I've developed a new engine that can accelerate at 1G continuously. Within about a year, I'm nearing the speed of light. Naturally, I recognize the danger of collisions with gas and ...

Q&A Could solar sails and solar wind plausibly decelerate a ship traveling at 0.05c?

In my story interstellar travel is common, but nothing's perfect, and a mining ship returning from a deep-space run (you'd be surprised what's out there) just discovered that something is very, ver...

Q&A Can a Lagrange point move relative to other forces acting on it

In this recently asked question on a large, sun blocking object it is pointed out in the comments that there would be ~10e7 N of thrust from the sun due to solar wind. My question is does there ex...
