One way to answer it is to turn to the solipsistic way—that is, there is no outside universe, but there are laws which convert one experience into the next one. I would not try to defend the point, as it has one clear weakness: it is not parsimonious, as it requires extremely complex laws to convert one experience in the next, and, more over, these laws are exactly the outside world, after some normalisation.
That is my view precisely. One way out is to assert that there is at least one mind responsible for providing the percepts available to other minds, and from its perspective nothing is unknown and it fills the function of the “outside world”.
