PARALLEL WORLDS HIDDEN INSIDE EARTH! It seems that scientists find more and more evidence to prove the existence of parallel worlds. Physicists at Stanford University managed to calculate the hypothetical number of universes that were formed as a result of the Big Bang. According to them, the Big Bang created 101016 universes. It is quite possible, though, that they may exist inside one another, including our planet. Therefore, there is probably another Earth hidden inside planet Earth.
