Theoretical Basis
The hole into the other dimension is an example of a "Riemannian cut", which is a type of wormhole formed by two spaces being joined at the same set of points. The uncertainty of whether the other dimension was the fourth or fifth would point to a question of the dimensionality of the space our three dimensional universe is connected to or embedded in.

Famous quotes containing the words theoretical and/or basis:
“The hypothesis I wish to advance is that ... the language of morality is in ... grave disorder.... What we possess, if this is true, are the fragments of a conceptual scheme, parts of which now lack those contexts from which their significance derived. We possess indeed simulacra of morality, we continue to use many of the key expressions. But we have—very largely if not entirely—lost our comprehension, both theoretical and practical, of morality.”
—Alasdair Chalmers MacIntyre (b. 1929)
“The primacy of the word, basis of the human psyche, that has in our age been used for mind-bending persuasion and brain-washing pulp, disgraced by Goebbels and debased by advertising copy, remains a force for freedom that flies out between all bars.”
—Nadine Gordimer (b. 1923)
