The concept of time traveling is a common one in fiction, giving rise and prominence to the concept of the butterfly effect. But is the butterfly effect accurate? And how much of a place must it hold in the case of writing time travel? Steins;Gate has entered the chat to put a lid on the matter with its clever time mechanic called "The once percent barrier" which limits the degree of the butterfly effect's reach. Join us as we talk about the interact of the one percent barrier and what we can draw from it conceptually to enrich the way we execute time travel in our work.
