No, the many worlds interpretation has nothing to do with whether or not someone is looking at schroedinger's cat.

yes

If the many worlds interpretation of quantum mechanics is true, then when did it start? when were the first two branches of reality created? the first mili-mili-mili-mili-mili-mili-mili-mili-mili second after the burst of energy that created the first matter and anti-matter right? so then wouldnt some branches of reality have a totally different universe resulting from even the slightest change in during the big bang? even one where you could do things liek...travel to other branches of reality?
