In the News (from JSpace): “Physicists have long known that quantum particles can influence each other regardless of how much distance is between them in a phenomenon Einstein mockingly called ‘spooky action at a distance.’ Now, scientists at Hebrew University’s Racah Institute of Physics have proven that this rule holds true for quantum particles that do not even exist at the same time.
“Einstein’s observation, called entanglement, describes the uncertainty principle in quantum mechanics. Quantum particles of light, called photons, exist in a haze of uncertainty, and can be polarized horizontally, vertically, or, bafflingly, in both directions. However, the moment a particle is tested for polarization, the uncertainty collapses and the photon is polarized in only one direction.
“Entanglement occurs when there are two photons. Each can be polarized in one of the three directions, but entanglement links the polarization of these particles even when they are each undetermined. So when the first photon is measured as having collapsed into a vertical polarization, the second has simultaneously collapsed horizontally, no matter how far away it is.
“According to findings published in Physical Review Letters, Israeli scientists have entangled photons that don’t even exist at the same time. Eli Megidish, Hagai Eisenberg, and colleagues from Hebrew University used a scheme called entanglement swapping to prove that two photons that don’t even exist in the same moment can be entangled. The key was to use two pairs of entangled photons, and then to force a photon from each pair to become entangled with the other.
“This advance expands the reach of quantum theory’s implications. Additionally, the experiment could improve long-distance cryptography by allowing long-distance users to be linked by a quantum network.”
My Comment: We are getting closer to the border with the upper world that exists beyond time and space, but science will have to stop at its boundary because further a different mind will be required that the human being will be able to obtain only by changing his properties from egoism to altruism. In this case, he will be able to understand the actions of the upper world described in the wisdom of Kabbalah.
