This could allow instantaneous communication with astronauts across the solar system, or even, the universe, if a sufficiently large repository of such entangled photons were stored onboard the spacecraft. A computer could change the spins of the stored photons as though they were binary digits in a communication channel (likely permanently destroying their future usability), with the remote repository instantly displaying the information, or even, communicating the voice data used.

No longer would we be bound by the speed of light in our communications.

In fact, this could be a wonderfully useful item in reducing the time it takes for solar flare information to arrive on Earth from a remote satellite or in even just with communicating information from halfway around the world without delay.

When the researchers measured several properties of each photon at its destination, they found that the particles could instantly sense the other´s behavior without any known communication. Although this correlation obeys the laws of quantum mechanics, it seems to defy the nature of space and time, at least from humans´ everyday perspectives.

Did your series of experiments arrive at the same conclusion?

Because it’s the same photon (electron)!

Thanks ConservativeMind. Also pinged you to a different topic, a one time "thank you" type thing. :')

Physicists sent two photons down optical fibers toward different destinations, and found that the photons could instantly sense each other's behavior.

This is an odd phenomena, and perhaps “odd” is the biggest understatement of all time.

Now Einstein and his followers were convinced that it was not possible, because at the time, there was no way to measure it. So he and his group speculated about “hidden variables”, in other words things like maybe an electron has more states that just it’s mass and charge and momentum.

Now Bell comes along. He proves:

Either Einsteins theory of locality was true, or quantum logic was true. There was no middle ground.

He also proves:

There is no “hidden variable” theory that could be added to classical or relativistic mechanics that would match the predictions of quantum logic.

So...

Bell, in an odd way, proved the multiverse theory. The universe is not a single thing sitting there, not a single set of rules.
There are rules that apply to things that are entirely consistent. There are other sets of rules that apply to the same time/place that are also entirely consistent.
Nothing in the first rule set invalidates anything in the second set, or vice versa.

The universe is pink.
The universe is blue.
Depends on where you are.
Also depends on who you are.
Also depends on where you are going and how fast.

Thanks for the post. Fascinating.

BTW, there is somewhat of a negative to the whole faster than light thingie.

Faster than light means we are not bound by space, but neither are we bound by time.

So if you get up in the morning and go out the front door and there’s a pterodactyl waiting there who rips your right arm off and flies away... well chit happens and it would be consistent with all the stuff Bell proved!
Faster than light means ALL space might be connected, and ALL TIME as well.

There is no instant communication at a distance faster than light. This will not lead to sending signals instantly throughout the universe. The scientists are seeing a phenomenon that they can’t explain, and are trying to explain it by saying stupid things.

My view is at the core of all things, be it matter, energy, photons, quarks, or something even smaller, exists “something” that pre-exists the Big Bang (cannot be created or destroyed). These things are “half-in and half-out” our universe. To me, this explains the phenomena of why linked photons appear to communicate faster than light - their communication link bypasses the universe’s 3-dimensional space (i.e., they communicate outside the universe, probably within the interstices between universes). Since “time” is within the universe, and “notime” is outside it, communication between any two points within the universe becomes instantaneous from our point of view.

This explains God’s omniscience - how he’s able to know anything, anywhere in the universe, as it happens. This also partially explains the bizarre biblical description that God commands inanimate objects (i.e., instead of doing an active action on an object, he commands it, expecting the “inanimate” object to both comprehend him and do what he commands).

Of course, Joseph Smith back in the 1830s came up with the idea of the “uncreated intelligence” that all things are built around, including our spirits, that is co-eternal with God and cannot be created or destroyed, not even by him, so it’s hardly original with me.

I haven't read it in detail but it looks like Wikipedia has a pretty good article on the subject of "spooky action at a distance".

Bell's Theorem

If you willing to read the discussion of the corellations and put a little energy into understanding it you will see that quantum mechanical theory correctly predicts the results of the experiment described in the article. That result, while counter-intuitive, is not surprising to anyone who understands quantum mechanics. But of course nobody actually understands quantum mechanical theory - they just know how to predict it's consequences.

One theory that takes some getting used to is that space and time are essentially the same thing. This means if you function like we do, time seems to be linear, and space has distance.

However, if *either* space or time are different for you, or don’t even affect you, then time and space will be very different, at least from your point of view, as it were.

It has been theorized that all matter and energy is just a single field, that is “out of time”. Therefore it can exist in a multitude of places and in different states simultaneously, at least from our point of view. When it clusters together, it appears to form increasingly immense super-clusters with radically different compositions.

Everything in the universe is just endless iterations of a single field, from our point of view. From its point of view, it is just one.

A vast number of iterations of this single field would be needed to even create a subatomic particle. On a grand scale, there are mathematically optimal stable configurations that form the organizational patterns of our universe, for example. Beyond a certain size, patterns are dependent on these configurations for stability. For example, the triangle and the sphere. They “last” longer, whereas other configurations are less stable and break up.

So, this being said, look at our “matched pair” of photons. In truth, all photons are “matched” to each other in complex stable configuration, but these two are identical twins. Mirror images, and importantly, they may be the same photon. From their “point of view” they occupy the same space and time, even if they are a billion miles apart, from our “point of view”.

This is how they achieve “spooky action at a distance”. Because they are the same photon, just with a different space and time from ours. If “they” are in reality “it”, than when we change “it”, “they” both appear to change at the same time. They don’t have to communicate with each other, because they are the same thing.

Importantly, this also implies that photons have some degree of individuality. Otherwise, when a single photon was changed, every other photon in the universe would also change, and not just its matched pair.

Who knows? Perhaps when we change the spin of a photon, it also changes the spin of a quadrillion quadrillion other photons in the universe. But we only see the change in the photon twin we are watching.
