Kurzbeschreibung (VLB): As 'Faster-Than-Light Particles' G. Feinberg introduced tachyons in
1967. The characteristic quantity for tachyons is their momentum parameter instead of the rest
mass of particles. We point out the difference between the terms correlation and interaction.
We find tachyons as solutions of the sine-Gordon equation over a lattice structure what was
first done by G. Eilenberger 1981. We investigate collision processes with tachyons and discuss
hypothetical consequences concerning particle creation and dark energy. We demonstrate how the
Einstein-Podolsky-Rosen paradox can be explained using instantaneous zero-energy tachyons and
thus give a model for Zeilinger's teleportation of 1997.
