“…4), a case we'll call Early Delft (ED). 10 In this case, the geometry seems to do a much better job of avoiding CL. The assumption NoRA ensures that A and B are not causes of C, at least partially removing the threat that C is a collider, and hence a source of collider bias.…”

A 2015 experiment by Hanson and Delft colleagues provided further confirmation that the quantum world violates the Bell inequalities, being the first Bell test to close two known experimental loopholes simultaneously. The experiment was also taken to provide new evidence of ‘spooky action at a distance’. Here we argue for caution about the latter claim. The Delft experiment relies on entanglement swapping, and our main claim is that this geometry introduces an additional loophole in the argument from violation of the Bell inequalities to action at a distance: the apparent action at a distance may be an artifact of ‘collider bias’. In the absence of retrocausality, the sensitivity of such experiments to this ‘Collider Loophole’ (CL) depends on the temporal relation between the entanglement swapping measurement C and the two measurements A and B between which we seek to infer a causal connection. CL looms large if the C is in the future of A and B, but not if C is in the past. The Delft experiment itself is the intermediate case, in which the separation is spacelike. We argue that this leaves it vulnerable to CL, unable to establish conclusively that it avoids it.

“…The result is spacelike causality, without direct AAD. The claimed advantage is that by keeping direct causal influences within the light cones, such models may be easier than conventional models to reconcile with special relativity; see [6][7][8][9][10] for recent discussions. In the present paper we ignore this option.…”

“…Some argue that quantum mechanics can be re-configured as a cellular automaton to eliminate annoying features, such as its inability to predict exactly where an electron is (Norsen & Price, 2021;Wetterich, 2021). This model leads to superdeterminism, which implies the absence of free will.…”

The concept of free will has challenged physicists, biologists, philosophers, and other professionals for decades. The constrained disorder principle (CDP) is a fundamental law that defines systems according to their inherent variability. It provides mechanisms for adapting to dynamic environments. This work examines the CDP's perspective of free will concerning various free will theories. Per the CDP, systems lack intentions, and the "freedom" to select and act is built into their design. The "freedom" is embedded within the response range determined by the boundaries of the systems' variability. This built-in and self-generating mechanism enables systems to cope with perturbations. According to the CDP, neither dualism nor an unknown metaphysical apparatus dictates choices. Brain variability facilitates cognitive adaptation to complex, unpredictable situations across various environments. Human behaviors and decisions reflect an underlying physical variability in the brain and other organs for dealing with unpredictable noises. Choices are not predetermined but reflect the ongoing adaptation processes to dynamic prssu½res. Malfunctions and disease states are characterized by inappropriate variability, reflecting an inability to respond adequately to perturbations. Incorporating CDP-based interventions can overcome malfunctions and disease states and improve decision processes. CDP-based second-generation artificial intelligence platforms improve interventions and are being evaluated to augment personal development, wellness, and health.

“…Furthermore, for two or more particles the coincidence probability density is connected to the total probability that appears in Bell type theorems which is a clear indication that the advanced term needs to be included in order to violate the classical correlations. This is obviously not a mathematical argument and the matter needs further consideration but it is plausible to assume that the effect of advanced terms in a many-particle context would definitely affect correlations and violate the usual assumed conditions for Bell-type theorems [14]. Obviously in the context of a classical electromagnetic or acoustic field there is no possibility of violating that family of inequalities but this is cerainly not the case for a quantum coincidence probability.…”

A nonlinear wave mechanical equation is proposed by inserting an imaginary quantum potential into the Schrödinger equation. An explicit expression for its solution is given under certain assumptions and it is shown that it entails attenuation related effects as non-unitary evolution, non-exponential quantum decay and entropy production. In the quantum hydrodynamical formulation the existence of circulation effects for the osmotic velocity field is established. Finally, a time-invariant equation for the probability density is derived, analogous to the tensor Lighthill equation in aeroacoustics, which admits both retarded and advanced solutions.

Lapsing Quickly into Fatalism: Bell on Backward Causation

Abstract: This is a dialogue between Huw Price and Travis Norsen, loosely inspired by a letter that Price received from J. S. Bell in 1988. The main topic of discussion is Bell’s views about retrocausal approaches to quantum theory and their relevance to contemporary issues.
