(urth) Wolfe vindicated!

[David Duffy]

I always thought the Autarch's explanation of how flyers work an in-joke 
by Wolfe, but saw a link today to:

(from http://www.physorg.com/news/2011-11-quantum-vacuum-dark.html)

Hajdukovic concludes:

the gravitational properties of antimatter [will] be tested in CERN before 
the end of the current decade (Kellerbauer et al. 2008) and that the 
recent theoretical considerations give some support to the gravitational 
repulsion between matter and antimatter (Villata 2011).

So, was this idea already floating around in the 60-70's?

Cheers, David Duffy.
