[ WP ] Write a time travel story that does n't create any paradoxes

`` So, it travels through time?'' 
 
 `` For the last time, NO!'' shouted the Professor. `` A ) Time travel is impossible along the linear concept we understand, as cause can not succeed effect, and B ) this is a cross-universe machine.'' 
 
 `` OK...'' paused Casey, the Prof's assistant. `` So, what does it do?'' 
 
 `` It opens the barriers between the infinite universes that are alongside our own. From my research on Membrane-theory, all other universes can be similar to our own, yet start at different stages.'' 
 
 `` Different... stages?'' 
 
 `` Let's call our reality'Universe-A.' Universe-A began 14.3 billion years ago with the Big Bang. Now, in Universe-B, the Big Bang was 143 billion years ago. In Universe-C, it was last Tuesday. In theory, we would be going into the past, or the future-'' 
 
 `` Without corrupting our own timeline!'' 
 
 `` Exactly! Now, I can establish an open bridge between our universe and any of the new ones we see.'' 
 
 `` So we can see what will - or did - happen to the world?'' 
 
 `` I know. Scary is n't it?'' 
 
 `` Yep. Let's go.'' 
 
 And with that, the Professor activated the Gate, took Casey's hand and jumped into the wild and chaotic unknown.
