By random I just mean that it truly could have gone a different way if you hypothetically went back in time. I just asked this question to help my understanding of the whole "other dimensions" thing. In my opinion it doesn't seem to be possible. With all the compiled laws and even the ones we haven't thought of only a set thing should happen, thus events in another dimension would have to be identical. For a different outcome to emerge the beginning would have to be different. I was just wondering if my hypothesis is logical. All of this is pretty much a guess for I do not have a degree in anything really, if I'm wrong I just want to know.
