Its testable just not with current tech

Then why ask philosophers? If you don't know what the other side of the moon looks like because rockets have not been invented yet, how could a philosopher possibly help?

Maybe not. It's not completely clear that, for example, string theory could ever be experimentally verified, since it operates completely at a level below all the manifestations of our observable universe. (AFAIK, I'm no physicist)

What technology can you imagine that could ever prove or disprove a hypothesis of our universe being only one facet of a multiverse? The apparatus would necessarily exist within the closed system.

does being in a multiverse influences our world in any way using current theories?

this is how you set apart a theory from speculation, a falsification test. i.e. > http://arxiv.org/abs/1210.1847

But the multiverse theory is in competition with other theories, some of which make the same predictions. If two or five or seventeen theories all make the same predictions, do you pick one? Which one? If you want to pick the simplest theory, what criteria do you use to figure out that one theory is simpler than another theory?

Can you elaborate?
