Yes; but — how on the basis of the scientific method would science actually be able to tell whether the effects in question were caused by an intelligent designer or a multiverse?

Science can say nothing about God unless you define God. Gravity outside of our universe suggests matter outside of our universe which suggests a parrallel universe. This supports multiverse theory.

Assumption of gravity outside the universe, *suggests*, *suggests*, *supports*

Speculation, not science.

Science can say nothing about God unless you define God.

Then science will have to hold its silence; for God cannot be "reduced" to human categories of thought....

You wrote that effects of gravity emanating from outside the universe suggest matter (mass) outside the universe; which further suggests a universe parallel to our own, which "supports multiverse theory." Well, fine. I'd just like to mention that gravity itself has not yet been fully explained, that it is the only one of the four fundamental forces of nature that so far has resisted unification with the other three. To look for theoretical support in a principle that is not yet fully understood seems rash to me.
