One thing that is interesting here is the is the durability of Penrose’s ideas. These were often decried by famous-for-a-day scoffers in the 1990s, but are now still referred to, or revived, when some of the original scoffers may be long forgotten. Here a popular science magazine reviews experiments relative to Penrose’s idea for quantum gravity. ‘The Secret Life of Reality’ by Michael Brooks, based on Roger Penrose, Cisco Gooding, Bill Unruh, Dirk Bouwmeester and other physicists as published in the New Scientist, January 3 2015.

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 […]
In this conference Donald Hoffman discussed why qualia are more relevant than Dennett had tried to argue in the 1990s. Another highlight was the exchange between Hameroff and Tegmark, where Tegmark took a surprisingly casual view of his much vaunted 2000 Paper.
In this interview with Ryan Cochrane, Kauffman outlines the mind-body problem in classical (i.e. non-quantum) physics. If the brain is a classical physical system, the current state of the brain, plus classically described inputs from the external environment, is entirely sufficient to causally determine the next state of the brain and the next state after that and so on.
Professor Larry Hunter along with colleagues at Amherst College and the University of Texas have published a paper in the journal ‘Science’ describing their attempt to study long-range spin interactions between quanta. Such interactions have previously been proposed but not observed. The physicists mapped electron polarisation resulting from the Earth’s geomagnetic field.
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 […]
