It is described in more details and called "causality attack" here : panoptesv.com/RPGs/Settings/VergeWorlds/… | |

Bonus points regarding the exotic matter: It's also used in some methods of near FTL travel, such as Runaway Motion allowing infinite acceleration in the direction of the negative center of mass, which while never hitting light speed would still get very, very fast. The negative mass in the drive could even be used at the destination for more stabilization of the wormhole. | |
| Nov 22, 2016 at 22:01 | comment | added | JDługosz | I read the PDF you noted. I recall something that was clearly (only) the wormhole empire idea through to merging empires. Google shows the term Empire Time is well understood now, with some uses in 2005 citing this work or Orion’s Arm. So I guess this portion of this thesis became a successful meme, even if few know the origin? | |
| Nov 22, 2016 at 19:58 | comment | added | JDługosz | I thought it was in a magazine, like Analog. But I can't recall clearly. | |
| Nov 21, 2016 at 22:43 | comment | added | Hypnosifl | @JDługosz - I added a link to the revised article Price wrote that appeared in Extropy, is it possible that's what you saw, or was it a similar presentation by a different author? | |
