Yes Joe;
Just watched the 'Through the Wormhole' episode.
There's a fair bit of hype and (over) dramatisation about it all.
I'm not sure why they see the S-T Theory as an alternative to BBT/Inflation. The way I see it, its kind of an extension, which provides some theoretical framework/explanation of how BBT could be extended by introducing extra dimensions and branes.
It all sits quite nicely with me. I have no major probs with the S-T Theory.
As I said earlier, the thing which is missing, is any empirical evidence … we should remember that M Theory is an extension of String Theory .. and there's only just now appearing, the beginnings of some types of empirical tests, formulated to enquire into the sanity (or otherwise) of Strings.
The major quest is to understand the concepts defined by BBT and then move onto M-Theory. Both can co-exist, I believe.
Cheers
