Ok, so you know how the Flash from Earth-TUD13 AKA the Flash from the DCEU movies/universe appeared in Part 4 of Crisis on Infinite Earths?. Well we were all wondering how he was still alive Because the Multiverse was destroyed and all the Doppelgängers with it. Well as you all can tell I, have a theory. My theory is that the movies, cartoons, TV shows, comics, and video games are in their own section. Imagine their are 4 circles. One circle represents the TV Multiverse, another represents the Game Multiverse, the next represents the Movie Multiverse, and finally the last one represents the Comic Multiverse from which all of these adaptations are based off of. Now judging from Part 4 of Crisis, the Barry Allen from Earth-TUD13 was surprised there was another version of him, and he was in the Speed Force along with his Earth-Prime counterpart. Just before they could get answers, Earth-TUD13 Flash fades away, but before fading away completely, he says “I told Victor this was possible” which means he was either trying to prove Victor the Multiverse was real, or it was an experiment. This Theory would make the most sense because if Earth-TUD13 Barry is from the Movie Multiverse then that means that Multiverse has its own version of the Speed Force. Since Crisis destroyed every earth across the Multiverse, that probably means the Speed Force was just floating out there

In space, all of its energy untouched and untapped. The connection was severed because the Multiverse was destroyed, along with space and time. So imagine it this way, one of the circles show red all over (because of all the Anti-Matter) and it’s spreading. The other 3 circles are right next to that circle and their borders are so close to each other. People can cross these borders because all 4 of them are a part of DC. That means in all 4 of these Multiverses they all have their own version of the Speed Force, doppelgängers, and probably the Monitor and Anti-Monitor. It’s almost like the Bubble Multiverse Theory but instead there’s a limited amount of vacuums/pots that create expanding universes. This vacuum has different types of high energy inside it. Like a pot on a stove, the energy inside of it starts to boil, then it evaporates into bubbles. Each bubble is a vacuum. Different types of energy, but lower than before. The bubbles start to expand and multiply inside the pot/vacuum instead of spreading out and the energy causes the bubbles to bump into each other. Imagine the Judeo Christian version of God in the DC verse does this 4 times and it creates 4 circles, Multiverses, or in this case Bubbles. But anyways that’s my theory. What do you guys think?.
