Different observations of the same reality (in photons) may both be correct

Since the Greeks, all western religions have ultimately had to be tested against reality.  Reality has had two components. The first is called the scientific method .. truth has to be reproducible.  The second is logic, 1 plus 1 must equal two and nothing can be both true and not true at the same time.

What is these laws of reality are not real.  What if two versions of reality exist at the same time?

Martin Ringbauer, a postdoctoral researcher at the University of Innsbrück in Austria, is a coauthor of a report in the physics  journal arXiv. Martin and a colleague set up an experiment where they both could look at the same photo at the same time.  One saw the photon spin horizontally, the other saw the amse photon, at the same moment, spin vertically.  Martin remarked “”You can verify both of them.”  The two conflicting realities were both true.

So, at least at this level the Greeks were wrong. 1 plus 1 may not equal two if each 1 may be a zero

Physicists call this idea of simultaneous reality “superposition.”  Elemental particles can exist simultaneously in two different states. Worse, this truth is not just a vagary of observation.   If the guy on the right above measures the photon and it is rotating vertically, thge particle will now have that property for the guy on the left. the property of this photon is fixed.  The reality of the two observers diverges but both are correct.

To ake this even more diffiult for ordinary humans, the Austrian physicists tested this theory using  two pairs of entangled photons, meaning that their fates were linked.  Entangled Knowing the state of one entangled photon automatically tells you the state of the other.

“It seems that, in contrast to classical physics, measurement results cannot be considered absolute truth but must be understood relative to the observer who performed the measurement,” Ringbauer said.
