ISBN-13: 9781563966538

Drawing on pivotal paintings through Einstein, Wheeler, Thorne, Hawking, and others, Matt Visser charts the improvement and present nation of Lorentzian wormhole physics. Dr. Visser exhibits that by way of pushing validated actual theories to their limits, it's attainable to infer the real physics of such exotica as wormholes and time go back and forth. The actual framework he makes use of is derived from one of many significant examine frontiers of contemporary theoretical physics: quantum gravity the intersection of classical Einstein gravity and quantum box conception.

Example text

We would like to stress this point emphatically. 2 The Properties of the Structures of the World at Every Scale Are of Quantum Nature. If They Were Not, We Would Not Exist The validity of this statement becomes apparent by noticing3 that the observed values of macroscopic properties, such as density, compressibility, specific heat, electrical resistance of solids and liquids as well as the mass of the stars, and their final fate (whether they eventually end up as white dwarfs, or neutron stars, or black holes) involve the universal constant h, the “trade mark” of particle-wave duality and of Quantum Mechanics (QM).

Because of charge conservation, the p þ can decay by emitting a W þ vector boson, which in turn disappears by creating a pair of leptons, of zero total lepton number and +1 charge (see Figs. 6). Such pairs are the positron and the e-neutrino or the antimuon and the μ-neutrino. l þ þ vl is much more probable. The same process can occur by the creation of a antimuon/μ-neutrino pair associated by the emission of a W À , which in turn annihilates the incoming p þ by being absorbed by it. Thus the corresponding Feynman diagram is as shown in the diagram b above.

In Fig. 7 In Fig. 3 we present through Feynman diagrams processes involving emission or absorption of photons by an electron or processes where an electron/positron pair appears or disappears. In Fig. 4 an important and characteristic process involving creation and transformation of particles through weak interaction is shown. Indeed, the main function of the weak interaction is to transform a quark or a lepton to another quark or to another lepton respectively by the emission of one of its two charged ic-particles which collectively are called vector bosons (W þ , W À ).
