Abstract
Once we have established in the previous chapter that negative PDOS is possible, one may naturally ask the question that can one transmit a signal in negative time. We answer this question affirmatively in this chapter. Once again the details of the proof depends on BC and is independent of the potential or model. The only requirement is that the system should sustain Fano resonances. We end the chapter with a small section called “reflections” which intends to imply that we are aware of the philosophical consequences but we are not willing to engage in a philosophical discussion at the moment. But we have hinted on what would be a physicists approach to such a philosophy.
