Quantum entanglement in time (December 12, 2020)
Quantum entanglement is often mentioned as a possible explanation of precognition. But how exactly are both phenomena related. Quantum entanglement is typically described as a correlation between particles separated in space, but for this phenomenon to account for precognition, the correlation must be also through time. It turns out that entanglement in time has also been extensively researched in recent years. Here is an article discussing several related findings with links to the corresponding scientific papers.

Quantum butterfly non-effect (September 23, 2020)
Recently, I cited a paper discussing the possibility of rewinding in time the state of a quantum computer. A new paper, published in Physical Review Letters describes research performed to check if a sort of a butterfly effect exists in quantum-entangled systems. To do that, they rewound back in time the system, changed its past by measuring a qubit, and checked if that affected the future state of the computer. It turns out that the effect, which is admitted to exist on a macroscopic level, does not work on the quantum level, at least in their setup.

Is the Universe a neural network? (September 15, 2020)
Physicist Vitaly Vanchurin proposes an outline of a Theory of Everything, in which quantum mechanics, gravity, the holographic principle, and string theory are all emergent from a model based on neural network dynamics. Could a neural network be the host of the "universal consciousness"? If all our universe's information is encoded in every point of space-time (as concluded by Star Gate researchers) perhaps that idea is not so crazy.

Dark matter imprints in Hubble telescope images (September 13, 2020)
Here is one more evidence that dark matter is… dark. Gravitational lensing produced by its mass is detected but the radiation emitted does not correspond to that mass. The article cites a theory suggesting that dark matter is invisible since it is in a parallel universe. Supposedly, the gravitational field of its mass is still in our universe.

Schrödinger’s cat unaffected by gravity (September 13, 2020)
Roger Penrose’s theory that the collapse of a wave function upon observation is due to the effect of space-time warping produced by macroscopic objects’ gravity has been put to the test. The results suggest that the theory is wrong, although its inventor considers there are still possible workarounds.

Schrödinger and the Upanishads (September 7, 2020)
Apparently, Schrödinger one of the founders of quantum mechanics was fascinated by the ancient Sanskrit philosophy of the Upanishads and found a profound source of inspiration in it. According to that philosophy, the inner self or soul called Atman is part of a universal consciousness identical to the Universe itself, called Brahman. Quantum physics in its modern form requires the observer to be considered as a part of any quantum system under study and shows unambiguously that the act of observation affects the experiment.
