Well its theoretical physics that predicts that physical space has 10 or 11 dimensions, but this doesn't prove the existence of parallel universes. To date, no physical experiments have confirmed the reality of any additional dimensions.
Another obstacle is how we each perceive space and time, with regards to the laws of thermodynamics, we have concepts of time that may well be incorrect, a four-dimensional manifold maybe manifesting right in front of us this very second, but until its confirmed then there's no reason to assume it is even there.
