I'm not so sure I can agree with that.
Deepening the quantum mysteries
In fact, the team has carried out several tests of the stranger predictions of quantum theory, but the most dramatic is what they call the "quantum eraser". In this variation on the Young's slit theme, the experiment is first set up in the usual way, and run to produce interference. Quantum theory says that the reason why interference can occur, even if light is a stream of photons, is that there is no way to find out, even in principle, which photon went through which slit. The "indeterminacy" allows fringes to appear.
But then Chiao and his colleagues ran the same experiment with polarising filters in front of each of the two slits. Any photon going one way would become "labelled" with left-handed circular polarization, while any photon going through the other slit is labelled with right-handed circular polarization. In this version of the experiment, it is possible in principle to tell which slit any particular photon arriving at the second screen went through. Sure enough, the interference pattern vanishes -- even though nobody ever actually looks to see which photon went through which slit.
Now comes the new trick -- the eraser. A third polarising filter is placed between the two slits and the second screen, to scramble up (or erase) the information about which photon went through which hole. Now, once again, it is impossible to tell which path any particular photon arriving at the second screen took through the experiment. And, sure enough, the interference pattern reappears!
The strange thing is that interference depends on "single photons" going through both slits "at once", but undetected. So how does a single photon arriving at the first screen know how it ought to behave in order to match the presence or absence of the erasing filter on the other side of the slits?
All of these experiments were carried out using beams of individual photons, and there is no way in which the results can be explained by using classical physics. They lay bare the mysteriousness of quantum mechanics in all its glory, and in particular demonstrate its "non local" nature -- the way in which a photon starting out on its journey behaves in a different way for each experimental setup, as if it knew in advance what kind of experiment it was about to go through.
(I love this stuff! -- This is where science ends, and spiritality/mysticism takes over!)
Science ended just a little before this. This is thoroughly in the mysticism/religion area.
At some point, science does break down. Scientific theory has never explained the "Big Bang," even though it's one of science's favorite theories. Theories can predict and describe events nano-seconds after the Big Bang event, but there's a wall that science hits, and can't get beyond, in describing events on the other side of that wall. Perhaps mysticism is as good a field of consideration as any at that point.
Well, at this point, the mysticism is Hindu.
A piece of a hologram contains only a piece of the total amount of information available in the entire hologram. When we view an object, we are seeing a portion of the entire wavefront that emanates from the object. Conventional photography, as well as your eyes, use the energy in that wavefront to create an image via chemical reactions in the imaging media; whether that be silver halide or the chemicals within the retina. A hologram works by recording the phase information of the wavefront as a whole rather than just the energy. It is then played back by using the interferogram to recreate the original wavefront. That new wavefront may then be imaged by your eyes or a camera just as the original was. But each small portion of a hologram only contains information about the part of the wavefront that impigned on that part of the hologram.
It is as though you are looking through a window that becomes suddenly smaller. The smaller window contains less information than the larger window did. The images seen through the window appear whole, but you lose the ability to move around within the window to see the object from different vantage points. As the window narrows, the object becomes more and more two dimensional. A "point hologram" is what one would get if they could "slice and dice" the larger hologram as far as they could. It looks like little more than a conventional two dimensional image.
That's been my theory all along. 'C' is only relative in terms of MPS where a second's duration on Earth is not the same as a second's duration elsewhere in the universe. So I've asked before - how can we state without error that the stars are light-years away when time (expressed as a year) is not relevant to light beyond our own earthly concept of time and Earth's position in space?

Their 10 eyes float in space
Let's look at them through a pair of my eyes
They look at me from holographic virtual space
My existence melts into their pseudo world
Am I existing?
Am I only a holographic projection of consciousness?
Or, just a dream in ukiyo, where everything are illusions in floating world
