QUANTUM ENTANGLEMENT AND SPEED OF LIGHT:

A friend wanted to know if instantaneous information by quantum entangled particles violates the condition that light has the ultimate speed. The problem lies in the definition of future. It is not like past or present. Everything "happens" at here-now. The light travels at here-now, though the "here" and "now" are extended. Whatever you are observing (स्वव्यापारारुढ) is covered in the term present. Of the rest - whatever you are not observing - the part that you can remember from its effects (अनुभुतिव्यञ्जक) is past. The part that you cannot remember, but can predict based on the available data that is likely to cause something (भवितव्यव्यञ्जक) is called future. Thus, these are digitized segments of analog time (त्र्यध्वाकाल).
Time is the ordered sequence of events. In a sequence (सातत्यगमने also भक्षणे), there can be only one direction. Otherwise there will be no sequence. Everything happens in time. Time does not do anything. Or times takes everything into its womb. It does not physically interact with others. There is nothing like a quantum entanglement. It is entanglement - micro or macro. Two ends of a rubber band are entangled. You can stretch it to a breaking point. It snaps, but the two ends of the new segments now become entangled. The earlier entanglement lasted only for some distance. Two poles of a magnet are entangled. Two ends of a quark are entangled. You stretch it sufficiently. It snaps to form two other quarks like the rubber band or the magnet, which again are entangled. There can be other entanglements like a pair of socks or proton-neutron combination inside of an atom. If by mistake you take only one sock, till you observe, both pairs of sock does not go into a hypothetical superposition of all possible states, but remain as they were. When we observe them, they suddenly do not acquire a fixed state, but whenever we observe, we will find the same state every time. Thus, superposition (अध्यास) is our insufficient knowledge or inability to know like seeing a dead tree in the darkness and imagining it as a thief or a ghost standing there. I had this experience in the childhood. After keen observation, I could differentiate between the immobile dead tree from a mobile person.
No entanglement lasts infinitely like a big rubber band. It snaps after some distance - may be a few kilometers. It has nothing to do with speed of light. It is like grandfather paradox. Alternatively, imagine a hundred meter triple chase. Everyone is running in one direction from the starting line to the finishing line. Some go faster than others. We see all at the same time in different places. Can we take an average and say some has run into future while some has gone into past, because we see them differently? We cannot "see" light (स्वयंज्योति). We "see" only the reflected light (रूपज्योति). That is how we perceive color. Sunlight contains radiation in all wavelengths. Only a few of it are reflected back by the object and this reflected light meets our eye. Then only we say this is red or blue etc. Even when we observe one entangled quantum particle, we use light pulses that are reflected back from the particles. This reflected light moves at the same speed. Until it reaches our receiver, it reaches at the same speed. Only then we can have information about it. Suppose you have taken one of a pair of socks - say the right one. After travelling to Moon or Mars, you see it and know that you have left the other one. Is it instantaneous information of some known state? No. You could have got the same information anywhere anytime. It is a wrong description of facts. It is sensationalization or fiction. It is not science. Hence light speed is not violated”.
