I have always been interested in the idea that our universe may not be the only one. Thus, I read with interest a New Scientist article called "Touching the Multiverse."

However, the article left me puzzled. To be frank, I could not really understand it all. The article suggested that recent work on mathematical modelling would lead to the opportunity to see if the multiverse is real. I can't see it.
To me, science is about empiricism. While computer models and maths models are useful tools, ultimately, the truth about various propositions must come from real world experiment or observation. Any scientific idea must lead to a prediction that can be tested in this way.
However, the multiverse idea appeals to me. It has always seemed to be the logical 'next step.' This may, of course, be totally wrong, but it would be nice to see the step taken, if possible.
Can anyone see a way to go that extra step, and test the idea?
