Even if it is a question of physics that doesn't mean it's an answerable one. There may be impenetrable barriers between us and any supposed higher-order multiverse. Even in this universe, it's possible to be entirely cut off from regions. What does a black hole look like inside its event horizon? We have models, but it's impossible to measure. On a larger scale, assuming the continue expansion of the universe, the furthest galaxies will eventually be receding from us faster than the speed of light, making them un-observable.
