Yes, creationists can certainly do research. But if they start with the infallibility of the Bible, it is not *scientific* research...possibly interesting and comforting to some, but not scientific.

And regarding alternate unseen universes, they certainly may (and probably do) exist, and may interact with the one we perceive. And we can never prove that they *don't* exist (see black swans above), but if there is a testable assertion or idea about their existence or nature, suddenly we are able to inquire about them in a scientific fashion. The testable assertion is key. "They exist" is not testable. "We know they exist because determining the spin state of a photon in Chicago should instantaneously affect the spin state of a coupled photon in Denmark" *is* (and was) testable! And the test results are a mind boggling example of quantum weirdness.
