They’ve published their
groundbreaking research in this week’s edition of the journal
This is the first time that scientists have succeeded in masking an event, though research teams have in recent years made remarkable strides in cloaking objects.
Researchers at the University of Texas,
Dallas, last year harnessed the
mirage effect to make objects
vanish. And in 2010, physicists at the University of St. Andrews
made leaps towards using metamaterials to trick human eyes into not
seeing what was right in front of them.
If the light doesn’t actually hit an
object, then that object won’t be visible to the human eye.
Researchers passed a beam of green light
down the cable, and had it move through a lens that split the light
into two frequencies, one moving slowly and the other faster. As
that was happening, they shot a red laser through the beams. Since
the laser “shooting” occurred during a teeny, tiny time gap, it was
For one, masking super-quick events,
like those that occur with data transmission, could help conceal
covert computer operations.
But it could be decades before military personnel will basically be able to zap history, as it happens:
