Uáháháháhá!

Que fâ de Ficção Científica, ou Engenhocas que se preze, não gosta de ver isto?




Video: Railgun Blasts an Aerodynamic Round Seven Kilometers Through A Steel Plate

By Paul Adams

This amazing video, created by Defense Tech, shows the latest test of General Atomics' high-speed railgun. Where earlier attempts have fired ungainly missiles that tumbled end-over-end through the air like "hypersonic bricks," this one uses a sabot round, which flies straight and smoothly for a distance of seven kilometers, AFTER punching through a solid steel plate. 




Voltando a falar de Ficção Científica, já se produziu a transmissão INSTANTÂNEA, como em, duma parte do Universo, para outra, de informação!
A parte mais "Uáháhá", é que a informação foi destruída num lado...
E apareceu no outro! 
Sim, é a realização na prática, da experiência teórica do gato de Schrödinger.

ISTO é a máquina onde se executou a experiência(!)

Researchers Succeed in Quantum Teleportation of Light Waves
By Rebecca Boyle

In a real-life use of Schrödinger's theoretical paradoxical cat, researchers report that they were able to quickly transfer a complex set of quantum information while preserving its integrity. The information, in the form of light, was manipulated in such a way that it existed in two states at the same time, and it was destroyed in one spot and recreated in another. The new breakthrough is a major step toward building safe, effective quantum computers.
No felines were harmed in the making of this experiment, which actually studied wave packets of light that existed in a state of quantum superposition, meaning they existed in two different phases simultaneously. This phenomenon is described in Erwin Schrodinger’s quantum mechanics thought experiment, in which a cat is simultaneously dead and alive, depending on the state of a subatomic particle.
