Einstein's theories of relativity suggest that gravity can cause time to slow down. Now scientists have demonstrated a way to stop time altogether—or at least, to give the appearance of time stopping by bending light to create a hole in time.
The new research builds on recent demonstrations of "invisibility cloaks" that can make objects seem to disappear by bending waves of visible light.
The idea is that, if light moves around an object instead of striking it, that light doesn't get scattered and reflected back to an observer, making the object essentially invisible.
Now Cornell University scientists have used a similar concept to create a hole in time, albeit a very short one: The effect lasts around 40 trillionths of a second.
pete spotts ('christian science monitor') picks it up:
At this point, the time gap that the scientists created is so brief – about 50 trillionths of a second – that practical implications are barely a gleam in anyone's eye. But the researchers are interested in trying to lengthen the amount of time a beam's gap remains open, says Alexander Gaeta, who led the team reporting the results in the Jan. 5 issue of the journal Nature.
In essence, the team briefly turned off a laser beam in a way that instruments receiving the beam could not detect. An observer would have no clue that the beam had blinked, and so would have no evidence of anything that happened to the beam in that 50 trillionths of a second.that's very interesting. and seemed good news. until i read nature.
'nature' tells you what the others step lightly around. these cornell researchers? government support. darpa. pentagon.
so the government's hoping to use this in warfare.
i'm so sick of these war pigs.
let's close with c.i.'s 'Iraq snapshot:'
