Planck Probe (2)

Posted by

Planck Probe (2) Based on Magee McKee, New Scientist, 5 October 2013 Recent observations from the Planck probe provide the best picture of the cosmic background radiation. Opinions are divided as to the significance of the recent evidence. Cosmoligists at Princeton view the latest evidence as creating problems for inflation theory, which has for some years been a consensus interpretation of the development of the early universe. Inflation theory has been used to account for the evenness Read more […]

Planck probe

Posted by

How new discoveries are rewriting the history of the cosmos Focus, October 2013 Summary of the above article Analysis of data from the European Space Agency’s Planck probe has revealed interesting new data about the early universe. Previously the background radiation of the early universe had appeared surprisingly uniform. Inflation theory which has been almost consensus over recent years was developed to explain this uniformity. However, the Planck probe has recorded a large cold spot, Read more […]

Mind-Like Universe

Mind-Like Universe Based on Paul Davies’s ‘Universes Galore’ – In: Universe or Multiverse, Ed. Carr, B. (2007) ISBN 978-0-521-84841-1 hardback In discussing the currently fashionable multiverse theory, Davies argues that it is not valid to simply propose that the inflationary phase of the early universe produced bubble universes, of which one happens to support organic life. Random production of universes is argued to be capable of producing paradoxes, for instance a finite universe with an Read more […]

Three Roads to Quantum Gravity

Posted by

Lee Smolin Wiedenfeld & Nicholson Smolin highlights the argument that space or spacetime is not continous but comes in discrete units, and further that these discrete units represent an organised structure. He stresses the conflict between relativity and quantum theory and argues that a theory of quantum gravity is needed to bridge the gap, describe the nature of spacetime and ultimately the origin of the universe. In relativity, gravity manifests the structure of spacetime, which is Read more […]

Quantum Approaches to Consciousness Harald Atmanspacher Stanford Encyclopedia of Philosophy Atmanspacher starts his article by stressing that the randomness inherent in quantum theory is in sharp contrast to the determinism that permeates classical physics. This randomness is a fundamental characteristic of the theory, not a result of ignorance of the full system, as is the case in statistical mechanics. Atmanspacher is also careful to draw a clear distinction between correlation and Read more […]

Aesthetics and emotion

Posted by

Aesthetics   Emotion, consciousness, aesthetics and subjective value assessments   Neuroaesthetics Eds: Martin Skrov & Oshin Vartanian INTRODUCTION: The parts of the this book dealt with here emphasise the role of the orbitofrontal and other brains regions connected with emotional processing in the creation of aesthetic preferences. In these studies, aesthetic preference does not appear to be the result of the rational processing of abstract rules, but of a value assessment based Read more […]

Ellis on technology

Posted by

http://quantumconsciousness.org/ Ellis takes a generally sceptical view of cosmology’s attempts to explain the origins of the universe, and in particular emphasises the difficulties of substantiating the currently fashionable inflation theory. He argues that attempts at explaining the origin of the universe depend on assuming that at least some of the laws that govern spacetime in our universe also comprised a pre-existing set of physical laws before the Big Bang. They assume the properties of Read more […]

Photons out of empty space

Posted by

Photons out of empty space Michael Brooks based on Chris Wilson et al, Chalmers University of Technology, Gothenburg New Scientist, 19 November 2011 A recent experiment by Chris Wilson et al at Chalmers University of Technology in Gothenburg serves to substantiate the prediction that energy in the form of photons could be derived from empty space. The prediction was based on uncertainty principle, which does not permit permanent zero energy, but specifies a fluctuation between zero and a Read more […]

Marcus Chown on physical laws

The Never Ending Days of Being Dead: Dispatches from the Front Line of Science Marcus Chown The ideas discussed in this book look crucial to our understanding of spacetime, energy, matter, the physical law and the relationship of consciousness to all of these. Spacetime and the energy it contains are viewed as fundamental, while quantum particles are suggested to be less fundamental being distortions of the underlying spacetime. This could be seen as related to the Penrose suggestion of objective Read more […]
