-
The timelike sigma-model case is well-defined and stable when the vector norm is fixed by a constraint; however, when it is determined by minimizing a potential there is necessarily a tachyonic ghost, and therefore an instability.

To alter/change the present time, one would need “miracle” performing tachyonic “future-arrow” particles, sending a certain volume of these particles across the “now” without them coming into contact of local “now” particles, and hopefully they have a direct hit on the “target_location_area” of the past.

Bandersnatchi are usually easy personalities, jumping about with great abandon and haste tachyonic state.
-
For example, all equations in field theory with tachyonic modes are unstable because the tachyons particles with negative squared mass grow with time exponentially for reasonable initial conditions.
-
Our modified action turns on a new degree of freedom, which is a massive (tachyonic) spin-0 particle.
