I have learned yet another astounding thing about light recently.
I knew some time ago that if you shine an equal amount of light from a certain distance toward two side-by-side apertures with identical photon-detectors behind, the photons tend to prefer one hole to the other, and will accumulate much more on that side. This implies that the light makes a 'decision' about which hole to go through, even though it is supposed to travel in perfectly straight, undeviating lines.
Then I heard about 'twinned' photons. Some photons are created as identical twins (don't ask me how or why) which can be separated. If you do something to/with one of them, its twin will respond in a completely identical way, even at some distance apart. The other side of the Universe, for instance.
This opens up the way for real-life teleportation.
There is a lot of work going into this phenomena (as predicted by Einstein, again) in China right now, but they are using twinned photons to create the world's first Quantum Computer.
When the computer is perfected, information will be able to be instantly sent to another computer - possibly on the other side of the Universe - without the need for even fibre-optic cables.
What will they think of next?
