In the well-known EPR paper, Einstein et al. called the nonlocal correlation in quantum entanglement as ‘spooky action at a distance’. If the spooky action does exist, what is its speed? All previous experiments along this direction have locality and freedom-of-choice loopholes. Here, we strictly closed the loopholes by observing a 12-hour continuous violation of Bell inequality and concluded that the lower bound speed of ‘spooky action’ was four orders of magnitude of the speed of light if the…

Non-quantum entanglement through time and gravity
In our previous paper [1] we show a paradox that leads to the conclusion that anti- matter must have "anti-gravity". Based on this conclusion we claim that matter and anti-matter preserve two new

It is proposed that photons may entangle over large distances only if some interaction exists via fields that cannot propagate faster than the speed of light, and an experiment to settle this ‘interaction hypothesis’ is suggested.
Four Mysteries Solved: Double-Slit, Spooky Action, Tunneling, and Accelerating Universe
There are more phenomena in quantum mechanics and in cosmology that we cannot imagine how they work. The four most known phenomena are the result of the double-slit experiment, the spooky action at a
‘Spooky action at a distance’ in the Micropolar Electromagnetic Theory
Still now there are no theoretical background for explanation of physical phenomena of ‘spooky action at a distance’ as a quantum superposition of quantum particles. Several experiments shows that

The quantum entanglement, that violates the local realism and other classical physics theories, leads to various counterintuitive phenomena, is a primary feature of quantum mechanics and probably
Experimental test of the collapse time of a delocalized photon state
We investigate whether the collapse of the quantum state of a single photon split between two space-like separated places takes a nonvanishing time. We realize this by using a source of heralded
Emergent Quantum Mechanics and the Origin of Quantum Non-local Correlations
A geometric interpretation for quantum correlations and entanglement according to a particular framework of emergent quantum mechanics is developed. The mechanism described is based on two
Super theory of relativity-explanation to 'rest mass of photon', 'quantum entanglement' and 'consciousness'
Siva’s theories explained the necessity of new theory for description of the Universe, space ,time ,space-time and matter. It explained the formation of ‘space time continuum’ in terms of ‘Films of
Quantum mechanics in terms of realism
We expound an alternative to the Copenhagen interpretation of the formalism of nonrelativistic quantum mechanics. The basic difference is that the new interpretation is formulated in the language of
