Interesting ATO article from Jeff Foust

Interesting stuff. I still have difficulty wrapping my brain around this. JP & company have been one of the most sober parts of the alt.space community for years; they simply cannot be dismissed as cranks or frauds. However, this is the most out-of-the-box concept I've ever seen, which makes it awfully difficult to accept.
Cheers,
Nathan.
