The Fast Forward Force Field is a reaction found by Dietrich Leithner in May 1994 involving a lightweight spaceship and three gliders. In the absence of the incoming lightweight spaceship from the left, the gliders would simply annihilate one another, but as shown they give the illusion that the spaceship advances 11 spaces in the course of the next 6 generations, i.e., is "teleported". Leithner named the Fast Forward Force Field in honour of his favourite science fiction writer, the physicist Robert L. Forward.
| Three overlaid universes; blue: spaceship alone green: both red: force field without spaceship a LWSS is formed on generation 6, but is destroyed by the debris that the incoming LWSS supresses it takes 22 iterations for the perturbation from the ship to travel 19 cells to the frontend, and appears to have been shifted forwards by 8 cells (from its initial trajectory) and phase-alternated (click above to open LifeViewer) |
