I am not sure where this would be put, as it the whole topic is built from various subject but here it is. Time itself is a set of rational and specific events that take place on the time line. In each sequence of events, you make decisions. With each choice comes a different outcome. As an example, if you act a certain way, someone will perceive differently. Well, with that, their are multiple outcomes that can come. By making a certain choice, it alters the time line. So who is too say that their are multiple timelines branched off a main timeline. Thus, making nearly a infinite number of timelines. By making a incision in the space time continuum, you could jump through the time lines to a specific time and place.
Here is where space travel comes in. A light-year or light year is a unit of measurement of length, specifically the distance that light travels in a vacuum in one year. Well, what if a light year is not a measurement of length, but a measurement of time needed to travel. Using a telescope in space, we receive images from distant galaxies millions of light years away. Well, using a rip within the time vortex, we could travel to previous and distant universes that eroded in time. Thus, we could use light years to jump through different timelines to get through a specific destination in the past, in space. Like Light speed, only we travel in the past to view past constellations.
