Download e-book for iPad: The Big Bang Never Happened - A Startling Refutation of the by Eric Lerner

By Eric Lerner

A enchanting problem to orthodox cosmology with strong implications not just for cosmology itself but in addition for our notions of time, God, and human nature -- with a brand new Preface addressing the newest advancements within the field.

Far-ranging and provocative, the massive Bang by no means occurred is greater than a critique of 1 of the first theories of astronomy -- that the universe seemed out of nothingness in one cataclysmic explosion ten to 20 billion years in the past. Drawing on new discoveries in particle physics and thermodynamics in addition to on readings in historical past and philosophy, Eric J. Lerner confronts the values in the back of the massive Bang conception: the assumption that mathematical formulae are greater to empirical remark; that the universe is finite and decaying; and that it could possibly purely come into being via a few outdoors strength. With inspiring boldness and medical rigor, he deals a brilliantly orchestrated argument that generates explosive highbrow debate.

Get Lucifer's Legacy: The Meaning of Asymmetry PDF

By Frank Close

ISBN-10: 0198503806

ISBN-13: 9780198503804

For plenty of centuries, scientists have investigated the "fearful symmetry" that looked as if it would underlie the Universe. yet more and more, it seems as if existence is the results of cosmic asymmetry, and scientists at the moment are getting ready to discover the asymmetries on the center of the large Bang.
As we commence a brand new millennium, it turns into clearer that real realizing of our Universe will come in simple terms from choosing and knowing the asymmetries that encompass us. whereas sleek medical thought describes a uniformly ideal and symmetrical production, we all know that have been that so, subject may were destroyed inside of an rapid of its visual appeal and not anything that we now be aware of may possibly ever have occurred. not just cosmic lifestyles yet our personal daily type is stuffed with different examples of asymmetry, from the human physique to the molecules of lifestyles. In Lucifer's Legacy, physicist Frank shut explores the origins of asymmetry from the molecular point to the Universe at huge, and asks no matter if this multitude of examples may be traced again to a unmarried occasion that happened on the beginning of our Universe. encouraged via an opportunity come across with a statue of Lucifer within the Tuillerie gardens in Paris, shut takes the reader on a sweeping journey of asymmetry on the planet round us, from the advance of human embryos to the mysterious Higgs boson. His journey culminates within the examine now underway at CERN to recreate the large Bang in Switzerland in 2005 and hence to resolve this secret of the unique asymmetry.
Vividly and engagingly written, Lucifer's Legacy finds that each time asymmetry happens in Nature, it issues in the direction of deeper truths.

New PDF release: Quantum theory and the brain

By Donald M.J.

A human mind operates as a trend of switching. An summary definitionof a quantum mechanical swap is given which permits for the continuous random fluctuations within the hot rainy atmosphere of the mind. between numerous switch-like entities within the mind, we decide to target the sodium channel proteins. After explaining what those are, we examine the ways that our definition of a quantum swap should be happy by means of parts of such proteins. We calculate the perturbing results of standard adaptations in temperature and electrical box at the quantum country of such aportion. those are proven to be appropriate in the fluctuations allowed for through our definition. details processing and unpredictability within the mind are mentioned. the final word aim underlying the paper is an research of quantum dimension conception in response to an summary definition of the actual manifestations of consciousness.The paper is written for physicists without previous wisdom of neurophysiology, yet adequate introductory fabric has additionally been incorporated to permit neurophysiologists without previous wisdom of quantum mechanics to stick with the principal arguments.

Olbers' paradox states that given the Universe is unbounded, ruled through the traditional legislation of physics, and populated by means of gentle resources, the evening sky will be ablaze with mild. evidently this isn't so. notwithstanding, the ambiguity doesn't lie in nature yet in our figuring out of physics. A Universe with a finite age, similar to follows from big-bang conception, unavoidably has galaxies of finite age. this suggests we will be able to merely see a number of the galaxies within the Universe, that's the most it is because the evening sky is darkish. simply how darkish may be calculated utilizing the astrophysics of galaxies and stars and the dynamics of relativistic cosmology.

We recognize from the dynamics of person galaxies and clusters of galaxies that almost all of topic that exerts gravitational forces isn't detectable through traditional telescopes. This darkish topic may have many varieties, and applicants comprise numerous forms of trouble-free debris in addition to vacuum fluctuations, black holes, and others. each one of these applicants are volatile to decay and bring photons. So darkish topic doesn't basically have an effect on the dynamics of the Universe, however the depth of intergalactic radiation in addition. Conversely, we will use observations of historical past radiation to constrain the character and density of darkish subject.

By evaluating observational information with cosmological thought in keeping with basic relativity and particle physics, darkish Sky, darkish topic stories our current knowing of the universe and the astrophysics of the evening sky and darkish subject.
