What if the worlds of alll those novels, manga,s, comics, video games, anime, cartoons, animated movies, live-action TV shows and live action movies you have read, played and/or seen shared the same universe? Well, it's obvious that they all cannot exist on the same earth at the same time, so one may happen in the past, some in the present and others in the future. Today, we will only be seeing if this timeline is possible. But before we get to that, I would like to introduce you to one man, now deceased, who unknowingly contributed in a major way to this project. His name was William James
A American philospher, William James, on the October of 1895, while writing a book titled "Is Life Worth Living?" coined the term, Multiverse, saying, and I quote, "Visible nature is all plasticity and indifference, a multiverse, as one might call it, and not a universe." So, as you can see, he was the first to use the word, just not with the same meaning. A Multiverse is, simply put, a infinite number of universes.
Our own Milky Way galaxy may be part of a Multiverse. Whew, you think this is complex? Get ready, we still have one last bit to power through. Pretty darn recently, a theory has been created that states that whenever a human comes to a decision in their life and makes one of two choices, a universe identical to this one is created where the other choice is made. Now, if you think that is a lot of worlds for just one guy, imagine it for 6 billion people, essentially everyone on the freaking planet.
So, with that being said, is the timeline possible? Ehhhh..... Maybe. Just maybe. But, here is the thing, because of the theory, there is NOT just going to be one timeline, instead, probably several. So this just got a whole lot more complicated. Then factor in technology levels, our entire goddamn history, and other shtuff, and WHEW. We have got a lot of stuff to tackle. But if you are willing to come along on this journey through the unknown, with me Malcolm Degrass Ty-I mean Malcolm Streitfeld, then we will accomplish so, so much...
