"Invisibility Cloaks" May Soon Be Real: Creating Invisibility With Superconducting Materials:

Invisibility devices may soon no longer be the stuff of science fiction. A new study published in the De Gruyter journal Nanophotonics by lead authors Huanyang Chen at Xiamen University, China, and Qiaoliang Bao, suggests the use of the material Molybdenum Trioxide (a-MoO3) to replace expensive and difficult to produce metamaterials in the emerging technology of novel optical devices.

The idea of an invisibility cloak may sound more like magic than science, but researchers are currently hard at work producing devices that can scatter and bend light in such a way that it creates the effect of invisibility.

Thus far these devices have relied on metamaterials – a material that has been specially engineered to possess novel properties not found in naturally occurring substances or in the individual particles of that material – but the study by Chen and co-authors suggests the use of a-MoO3 to create these invisibility devices.

Possessing some unique properties, this material can provide an excellent platform for controlling energy flow.

[...] As a result, the study shows that hyperbolic materials such as a-MoO3 and Vanadium pentoxide (V2O5) could serve as a new basis for transformation optics, opening the possibility of photonic devices beyond invisibility concentrators, including improved infrared imaging and detection systems.

    Let's say the US perfects this first. Number one!

    Within weeks, all of North, Central and South America go under direct US military control. In a fit of panic, some of Brazil's nukes get fired off randomly. Tens of millions dead.

    China manages to get the plans from an unsecured server. All of Asia goes under Chinese control in the following few weeks. AUKUS tries to protect their "interests" and bombs Shanghai. In response, China cloaks some nukes and drops one on NYC and one on Sydney.

    Stockmarket collapses. Global trade immediately halts. Hyperinflation becomes the norm overnight. Truce is quickly made.

    US gives tech to the UK and Isreal, China gives it to Russia and NK. "For mutual defense".

    Africa, the ME and Europe are inevitably carved up over the next few weeks in negotiations by the invisibility-owning powers. Shock troops just appear out of nowhere all over the planet, if a government or a people have any "issues" with the new arrangement.

    Police are given invisibility cloaks after they begin to voice concerns over safety. People begin to get fined/arrested everywhere for the most minuscule of infractions. Police and government claim that it is an amazing success. Now the population is totally under control - as every moment of the day some goon could be watching and listening to you. Between hidden visual observation indoors and enhanced satellite tracking outdoors, there is now no place for the uncloaked to hide. People still manage to struggle on through.

    Criminals kill a cop and get their hands on a cloak. Mafia scientists figure it out. Crime skyrockets to proportions never seen. There are battles in the street in every population center all over the world. Rapes and murders in insane numbers.

    Even the billionaire class on their islands are now helpless. Continued hyperinflation finally makes them as money-poor as the rest.

    We finally enter a world where the only way to speak without being recorded or noted is to hide and use finger touching inside the other persons' armpits, or other concealed area, or to kiss and use a tongue touching language. Although the second option falls out of favour as new Isreali tech can record the slurping sounds at a distance of 300 metres and can convert those sounds into text. The tech is enhanced and can soon translate any finger-touch communication, seen or unseen. All communication with others is now suspect. All personal safety has disappeared.

    Going to sleep now requires pills, as no one can get to sleep naturally - maybe someone is hiding in plain sight inside your very bedroom. Just waiting to murder and rape. Every little noise now produces shock, or maintains the shock, a slight puff of wind, a stick caught on your trousers, the buzz of an insect. Every room and every location must now be continually scanned. Simple concentration starts to become impossible under the stress. Almost the entire population go on stress inhibitors.

    A majority of people cross over the line into insanity and exhaustion as life becomes an unmanageable 24/7 paranoid nightmare. Millions of suicides. More drugs supplied to combat the psychological issues.

    Billions are then killed as the political and military class also finally succumb to total paranoia and psychopathy. Cloaking and killing each other in leadership spills. Stalin's work looks like a rounding-error, the Roman Empire leadership appears sane by comparison.

    It all finally settles down and Earth becomes a global Egypt / NK. Forever.

    The end.

    you have read far to much sci-fi, and not enough political hokum.

    I do not think it would be long before a significant number of blind people, armed with attack-bats and pepper spray, incapacitate the entire USA,

    Russia uses excessive force on nothing at all and incapacitates itself,

    Europe is incapacitated by inability to take any kind of decision,

    Sharks with Lasers incapacitate both North and South Korea,

    and Africa would carry on as normal - in complete shambles.
