Are topics like Multiverses outside of Science?

As far as I understand , science requires evidence and or experiments before you move on. If one comes across topics like a multiverse which have no evidence or scientific way of looking at the subject is there enough distinction made between such topic and maybe something like black holes which may have various theories but at least there are hung on something with some data and maybe more data will come in as technology improves?

are there any other topic that fall into this category? Wormholes (just guessing here) for instance? Time travel into ones past etc. any others?

Cosmology is the study of the universe as a whole: its structure, its origins and its fate. Fundamental physics is the study of reality's bedrock entities and their interactions. With these job descriptions it's no surprise that cosmology and fundamental physics share a lot of territory. You can't understand how the universe evolves after the Big Bang (a cosmology question) without understanding how matter, energy, space and time interact (a fundamental physics question). Recently, however, something remarkable has been happening in both these fields that's raising hackles with some scientists. As physicists George Ellis and Joseph Silk recently put it in "Nature":

"This year, debates in physics circles took a worrying turn. Faced with difficulties in applying fundamental theories to the observed Universe, some researchers called for a change in how theoretical physics is done. They began to argue — explicitly — that if a theory is sufficiently elegant and explanatory, it need not be tested experimentally, breaking with centuries of philosophical tradition of defining scientific knowledge as empirical."
