The concept of the following statements together cannot possibly be possible because it has logical errors.
1. There are an infinite number of universe in which each and every possible possibility has occured.
2. We can reach those other universes.
If every possibiltiy has occurred, than the possibility of someone or something destroying all the other universes from their own has occured, and thus we cannot possibly exist.
Therefore, you cannot communicate with these other universes, or they don't exist.
