[extropy-chat] "Hyperdrive Engine Could Let Us Reach Mars in3Hours"

[scerir]

There are many papers on Heim 'hyperdrive' here
http://www.hpcc-space.com/publications/index.html
and perhaps also here http://www.heim-theory.com

As far as I remember R. Chiao is working, since
long time, on e.m. <-> gravity transducers. That 
it to say a 'medium' (like a quantum Hall fluid,
or any other medium with a collective Berry phase, 
or the like) which may transform e.m. radiation in 
gravitational radiation and viceversa (btw, such a device 
would reveal the supposed gravitational cosmic background
radiation due to the Big Bang). This is, of course, 
different from a _direct_ interaction between 
photons and gravitons.
