Many Worlds Interpretation

Many Worlds Interpretation commonly abbreviated as MWI within the scientific community. Scientist, physicist, philosophers and every other person who practice ontology have been interested in the evolution of human and the very start of being. Some of the commonly known physicists and scientists such as Albert Einstein, Stephan Hawkings have proposed several theories about start of the universe and their theories about various topics. Among such topics are some long debated questions; are we alone in this universe, or are their any other universe. The fight for the right answer goes well beyond my scope of present knowledge. But a group of physicists are arguing about a Multiverse, in layman language, a universe existing parallel to ours. Some questions arise in the minds of scholars that even if they exist there is no way to prove the theory, even though mathematically there is a probability of  their existence. In a recent article i read there was one such debate ongoing whether the theory was right or wrong or even if the discussion for the same topic is worth or not. The major debatable topic among them was how to validate this scientific argument or rather a very specific judgement: Even if this is right there is no way to prove it. As much as i like to make a judgement for the decision but my knowledge for the history of the topic is limited. The author Sean Corell seemed too aggravated that the mere possibility of its validation was waved off because of the limitation of our technology and scope of knowledge. His basic proofs provided some mathematical explanations which seemed decent enough to be taken into consideration. Not to jump to conclusions here but i for one would like to take this topic more practically than theoretically. Not going with the explanation of the author lets not hastefully jump into conclusion. I would like the probability of its veracity to be taken into account along with other theories and lets take our chances on the most probable ones. I have no doubts that the scientist would have taken a lot of possibilities into account but no theories should be taken on faith.
