Swedish scientists have created for the first time
in the lab a perceptual illusion of having an
invisible body among humans. The experiment involved 125 participants
standing up and wearing a set of head-mounted
displays.
The participants were then asked to look down
at their bodies but instead of their real bodies,
they saw empty space. To evoke the feeling of having an invisible body,
scientists touched participants' body in various
locations with a large paintbrush while, with
another paintbrush held in the other hand,
exactly imitating the movements in mid-air in full
view of the participants. "Within less than a minute, the majority of the
participants started to transfer the sensation of
touch to the portion of empty space where they
saw the paintbrush move and experienced an
invisible body in that position," explained Arvid Guterstam, lead author from the Karolinska
Institutet in Sweden. In a previous study, the same team showed that
the same illusion can be created for a single hand.
"The present study demonstrates that the
'invisible hand illusion' can, surprisingly, be
extended to an entire invisible body," he noted. To demonstrate that the illusion actually worked,
the researchers would make a stabbing motion
with a knife toward the empty space that
represented the belly of the invisible body. The participants' sweat response to seeing the
knife was elevated while experiencing the
illusion but absent when the illusion was broken. "It suggests that the brain interprets the threat in
empty space as a threat directed toward one's
own body," the authors noted. In another experiment, the team examined
whether the feeling of invisibility affects social
anxiety by placing the participants in front of an
audience of strangers. "We found that their heart rate and self-reported
stress level during the 'performance' was lower
when they experienced the invisible body
illusion," Guterstam noted. The results are interesting because they show
that the perceived physical quality of the body
can change the way our brain processes social
cues. The results suggest that the feeling of invisibility
changes our physical stress response in
challenging social situations. The power of invisibility has long fascinated man
and inspired the works of many great authors
and philosophers such as renowned science
fiction writer H.G. Wells who wrote "The Invisible
Man".
Recent advances in materials science have shown that invisibility cloaking of large-scale
objects such as a human body might be possible
in the not-so-distant future.

The difference between the West and Africa is that they document these advances so it could be learnt, improved, and scaled. Africans will hide the knowledge, use it to exploit, and finally die with it without proper documentation of the theories. This always causes mystery and doubt.
