Title: Things ain't what they seemed

"There are now emerging a whole class of experiments, and theories to back them up, that involve the creation of materials that support electromagnetic wave propagation in ways that are not observed in nature," van der Weide says. "In other words, it's turning nature on its head. Some might ask, 'If you can only do this in artificial material, what good is it?' The answer is that we might be able to create materials that could support this type of effect for light or other electromagnetic waves.

The larger point is that physicists are starting to challenge what were thought to be the basic laws of nature."

In 1968, Russian theorist V.G. Veselago predicted that materials could be engineered to interact with their environment in the opposite of how natural materials react. In 2000, researchers at the University of California-San Diego (UCSD) confirmed this, creating what's known as the first "left-handed" material.

In nature, all materials appear to obey the "right-hand rule." If the fingers of the right hand represent the waves' electric field, and if the fingers curl around to the base of the hand, representing the magnetic field, then the outstretched thumb indicates the direction of the flow of power. But the UCSD team created material that caused fields to move to the left even though the electromagnetic energy moved to the right. Light waves produced by such material should also produce an inverted Doppler effect. Van der Weide's group, in collaboration with researchers at MIT and the University of Delaware, is also exploring left-handed media.

"This is kind of the tip of the iceberg in terms of discovering things that we've held to be inviolable. We're finding they can, in fact, be violated under certain conditions," van der Weide says. "Can we build structures that would support that kind of thing? The answer appears to be yes."

It seems reasonable that these materials could in fact render normal electronic surveillance and monitoring useless.  You wouldn't be able to detect the spy in a physical world.  Or, a mirror of what is rendered normally may prove to be unimpeded by bypassing 'natural' laws.  What do you think?

Hi Ken,

I think the more we learn, the more we learn how little we really know.

Shucks Ken, 

You know what I think.


I think you've been spying on me......


Here in 'Crossworld'.


meesa really tink Ken been spying....on z'meesa

engeneering new materials,over element 131 ? why not,when it would be usefull.
the designing of new or mass production of existent  elements in 100% concentration
is not more a problem with apparatus like the Chambrin-Transmuter or Browngas-Chamber.
for example ruthenium(graetzel-solar-cell).

Yeah, Tech, the NSA has been around here too and I feel them everytime I go out of the country.

NO comment.


Other than to say that one huge, gaping, unknown unknown has been blinking at them for over 23yrs.....

If a generator was wound so the windings have alternating directional fields
would that strip counter electro-magnetic forces, or to say remove resistence
and the required power required to mechanically turn the said generator?
