One of the most discussed topics among physicists, astronomers and cosmologists, is the origin of our universe. A number of theories have been put forward to explain the origin of the universe. Based on the evidence, the theory of Big Bang is widely accepted today. What is the Big Bang? Around 13.8 billion years ago, all the energy and the matter was compressed into a miniscule point. There was nothing else, no space or sky outside it. Everything was contained in that point. All at once, this point (which could not bear that high density and very high temperature), started expanding at an incredibly fast rate. In a split-second, it was the size of a grape, an instant later, a km-wide. Within...
From Ancient philosophy to contemporary theories of fiction, it is a common practice to relegate illusory appearances to the realm of the non-existent, like shadows on the wall of Plato’s cave. Contrary to this traditional mode of drawing a metaphysical distinction between reality and fiction, Markus Gabriel argues that the realm of the illusory, fictional, imaginary, and conceptually indeterminate is as real as it gets. Being in touch with reality need not and cannot require that we overcome appearances in order to grasp a meaningless reality which exists ‘out there,’ outside and maybe even beyond our minds. Human mindedness (Geist) exists in the mode of fictions through which we achi...
Space & Universe have always attracted human race. There have been several mystries associated with this. Humans have always & will continue to travel to find what exactly is hidden in space out there. I at age of 15 am no different & have plans to solve the mysteries. So come join me in understanding few mysteries.
In The One, particle physicist Heinrich Päs presents a bold idea: fundamentally, everything in the universe is an aspect of one unified whole. This idea, called monism, has a rich 3,000-year history: Plato believed that 'all is one', but monism was later rejected as irrational and suppressed as a heresy by the medieval Church. Nevertheless, monism persisted, inspiring Enlightenment science and Romantic poetry. Päs shows how monism could inspire physics today, how it could slice through the intellectual stagnation that has bogged down progress in modern physics and help science achieve the 'grand theory of everything' that it has been chasing for decades. Blending physics, philosophy, and the history of ideas, The One is an epic, mind-expanding journey through millennia of human thought and into the nature of reality itself.
This Carg` ese school of Particle physics is meant to bridge the narr- ing gap between astrophysical observations and particle physics. The lectures supply the students with a theoretical background which covers severalaspectsofthecosmologicalscenario: matter-antimatterasym- try, the nature of dark matter, the acceleration of the expansion and the cosmological constant and the geometry of the universe as well as m- ernviewsonparticlephysicsincludingsupersymmetry, extradimensions scenarii and neutrino oscillations. ix Preface TheinvestigationofnuclearabundancesbyAlpher, Bethe, andGamow (1948) was the?rst intrusion of subatomic physics into cosmology. In contrast with their assumption, most nu...
This book addresses foundational questions raised by observational and theoretical progress in modern cosmology. As the foundational volume of an emerging academic discipline, experts from relevant fields lay out the fundamental problems of contemporary cosmology and explore the routes toward finding possible solutions, for a broad academic audience.
