| Nov 6, 2019 at 3:14 | comment | added | a4android | @StarfishPrime Ah yes! I guess I just like seeing galaxies zoom past, before they disappear from view seconds later. These days everybody's in a hurry. | |

| Nov 4, 2019 at 15:15 | comment | added | catsteevens | Wonder what the top speed (light speed?) is for the next regime, c3. A multiple of 5 x 10^26? | |

| Nov 4, 2019 at 0:40 | comment | added | catsteevens | You are right, of course. The 32 billion light years from earth to the galaxy GN-z11 in a couple nanoseconds! Thanks. | |

It's not your job to explain the physics, not even to the satisfaction of any physicists who read your story. Show the spaceship reaching a critical velocity where it can transition from below to above lightspeed. Any technical details you can glean from Calvo-Mozo's paper the better the plausibility will be. Even physicist-readers will be happy with that, for the rest just get on with the story. Even if the physics isn't right, it's enough for a plausible version of FTL travel. | |
| Nov 3, 2019 at 23:54 | comment | added | catsteevens | You’re right, I’m not a scientist, I am (claim) a writer of fiction, so all I can do is glance over the preprint article and try to decipher something out of it. The different velocity regimes is new to me, and a cool concept I think. Have some starship accelerate up to some doable speed (.94c? He mentioned that) and transition/jump to the next so-called regime. Some high tech rocket/ warp engine physically employs that tiny constant ε^2 and the ship jumps into the next regime. Using a mole of electrons that he mentioned. :) | |
