Ontological Inertia acts as a buffer against changes to the cosmic status quo: You cannot (well, not completely) undo something that already exists.
 
Writer [[Fritz Leiber]] agreed with this trope in his ''Change War'' series of stories involving time travel, and devised the "Law of Reality Conservation" as a way to show how things couldn't just [[Ret -Gone|un-happen]]. In that context, it states that you ''can'' change the past (in fact he named one of the stories in the series, "Try and Change the Past"), but Fate will force a coincidental event to ensure that history proceeds down its intended path without paradox; every time you try to prevent one historical trend or event, a similar one will take its place in history.
 
On the other hand, what can happen instead is if you do change something in history that is significant, the time line "fractures", a whole new universe is created at that point, and you and the new event are in a completely different reality with the change you caused. So either you go back to your universe where the change never happened, or you end up going forward to the equivalent time in the new universe with the change that you made propagating from that point. If you don't like the result, you can try to go back and change time again, in which case, guess what, time "fractures" again to compensate for that new incident, and the cycle starts all over again.
