Problems with the Multiverse

At it's core, the multiverse theory is a bad one.

I think that the cultural sense of the multiverse is more like parallel universes such as the mirror universe on Star Trek - a universe which functions much as ours but with different people in it.

Many don't realize that its support among the scientific community comes from it being the only viable alternative explanation for the rampant order which we perceive in our universe. If there are numerous unknown universes with different physical constants, then we shouldn't be surprised to see our universe be as ordered as it is - after all, it'd have to be ordered in the first place for us to even exist to ask the questions.

I was discussing this with my friend today. It's not a scientific theory because it doesn't yet pose a potential experiment to falsify it. And it's not really a philosophical theory either since it doesn't so much build off of our logical conclusions and inferences. In reality, it is questioning a premise.

We see so much order in the universe that we have identified certain forces of order (gravity, evolution, etc.). The multiverse argument is really primarily questioning the premise that just because we see order, doesn't mean that there is order. "What if it's all really just chaos and order popped up one day in one corner of reality?" It's a fair question and of course, it's a possibility.

But it's a bad theory. If we take that premise that all of the order which we perceive is actually pure chaos at it's base, we have to throw out every idea we've ever had. Why should gravity work tomorrow? If it's all just chaos, it could stop functioning at any moment. So too with all of reality.

More so, when we allow the premise that the order which we see reflects some basic underlying order which we cannot see, we discover amazing principles and abilities - electricity, flight, etc.

I don't say that the multiverse theory is wrong per se. It is, of course, a possibility. But as an approach, it hasn't had as much success as the scientific or philosophical methods.
