Superluminal speeds and travels to the past in a screen with time delays
On the basis of an observation made at the interactive scientific exhibition Lugar a Dudas (Centro Cultural de la Ciencia, Buenos Aires, Argentina), we discuss a class of objects that, without violating Relativity Theory, move faster than light, and that emulate travels in time toward the past.

| Sumario: | On the basis of an observation made at the interactive scientific exhibition Lugar a Dudas (Centro Cultural de la Ciencia, Buenos Aires, Argentina), we discuss a class of objects that, without violating Relativity Theory, move faster than light, and that emulate travels in time toward the past. These objects are implemented by processing a video recording, to which suitable time delays are introduced over the image. In contrast with traditional examples of superluminal motion, they can be realized using ordinary experimental and computational resources, which emphasizes their didactic value. We formulate the mathematical description of the effect of time delays in the video images, and pose a series of questions in order to motivate further analysis. |
