Why is it the fact that they never can be joined again a solution for the problem that for two universes (where there was only one a second ago), you need twice the mass/energy total? The only possible solution I see is that simultaneous with the new universe that is created, an anti-universe (with antimatter etc.) starts to exist as well.

I have a problem with the reasoning 'we don't know what will happen, so both (or all) possibilities) are equally true'. They are equally valid as theoretical models until 'it' has happened, but only the 'real' one exists. We don't know if the cat is dead or alive, but it isn't both!

This is just a layman's view, I know that those that have proposed this model have thought a bit more about this, but I was irked a bit by your mail.
