The argument about entanglement goes back to Einstein. The notorious EPR (Einstein/Podolsky/Rosen) thought experiment of 1935 demonstrated that if quantum mechanics was correct then the determination of the state of one quantum particle could instantaneously and over any distance determine the state of another particle. This was afterwards referred to as entanglement or quantum entanglement.

The book, ‘The Science of Consciousness’ (published in June 2015) is authored by Eva Deli, and proposes a new hypothesis, which is rooted in string theory. The author considers the universe being divided by an information-blocking horizon into macrodimensions, called space, and microdimensions, called time.
ON SPECIAL RELATIVITY Based on material from Roger Penrose and David Bohm While quantum theory and still more its implications have been censored out of much of popular thought and education, relativity may have had the opposite fate of being popularised as a wow! factor, with possibly a lack of balance as to what is really important about the theory. Mass-energy equivalence It could be argued that mass-energy equivalence is of greater significance than more crowd-stopping ideas such as Read more […]
An understanding of the beginning of the universe requires an integration of general relativity and quantum theory or in other words a theory of quantum gravity. String theory has been the best known attempt at this with quanta described as the vibrations of one dimensional strings. However, alternative theories have emerged in recent years.
Molecule discovery suggests life could have started in space Focus: Science and Technology, Issue 275, December 2014 sciencefocus.com/ Summary and review of the above article An isopropyl cyanide molecule, the largest and most complex molecule to date found in interstellar space, has been discovered by the Atacama array in Chile. The discovery was located in a star-forming gas cloud. Dust in the cloud becomes heated, and chemical reactions on dust particles can give rise to complex molecules. Read more […]
Our Mathematical Universe Max Tegmark (2014) Summary and review of the above book The first part of this book is a readable guide to understanding physics and cosmology. Where it goes wrong is that the author gets out of his depth in trying to extend to non-consensual areas such as time, reality and consciousness. The discussion here starts well in identifying that the brain constructs a model of reality, which is consciousness, helped by the integrative brain hub scheme developed by neuroscientists Read more […]

Moreover, the mathematical primacy of complex and imaginary numbers suggests the primacy of complex and imaginary structures in Nature, while further implying the existence of imaginary spatial dimensions preceding real dimensions. On this basis a consistent cosmological Read more […]
Author: Philip J Carter, Invited article for the Journal of Neuroquantology Submission history [v1] 2013-12-26 14:51:58 [v2] 2014-01-16 12:49:26 A higher-dimensional spacetime model is proposed, accounting for nonlocal quantum phenomena while embracing Special Relativity as a limiting case. The Aspect and Megidish experiments are explained within this spacetime framework. Time is understood as spatial motion relative to higher dimensions, offering the degrees of freedom demanded by nonlocal Read more […]
Stuart Clarke, New Scientist, 4 January 2014 Summary of above article The article discusses the possibility of interactions between matter/quanta on the one hand and spacetime on the other, and in particular deals with the work of Giovanni Amelino-Camelia at the University of Rome La Sapienza. This is in connection with a powerful burst of gamma radiation from a galaxy at a distance of 500 million light years detected in 2005, and another much more distant burst of radiation observed in 2013. The Read more […]
The recent detection of gravitational waves, as predicted by relativity theory, also tends to confirm that a period of rapid inflation of the volume of space occurred in the very early universe. The observation by a telescope at the South Pole indicates a spiral twisting of primordial light waves, as a result of an inflationary phase shortly after the Big Bang. This discovery is somewhat comparable to the detection of the Higgs boson, which has also been predicted by physical theories, but was until Read more […]
