I watched a video somewhere about the chronovisor and that it is possible to capture something from the past or the future but that the big problem is that no one has yet being able to capture sequence of events either as a sequence of images or like a video but only single reflexes ( I mean single images showing something ) that contain no information of neither the year nor the date. So that means for example if you see a captured image of something future ( let's say a catastrophe such as a plane crash ) you won't be able to prevent it because you have no information or idea of the events prior to that nor after that. And neither do you have info about when.
