  12. The Physical Causes of Relativity 12 The Elements of Special Relativity • Contraction • Dilation • Constancy of c • Increase of Mass • Energy-Mass Relation ‘

  13. The Physical Causes of Relativity 13 Special Relativity:History of the contraction Electric fields contract at motion 1888: O. Heaviside Objects contract at motion 1889 G.F. FitzGerald Michelson-Morley apparatus contracts at motionwhich explains the null-result of the experiment: 1892: H.A. Lorentz Sufficient to understand relativity? The experiment cannot be explained by pure contraction Needs dilationalso 1932: R.J. Kennedy E.M.Thorndike ‘ ‘

  14. The Physical Causes of Relativity 14 Special Relativity:History of the internal motion Motion at c of the ‘smallest objects’ 1908: J. Ziegler Internal oscillation causes ‘matter waves’frequency: 1924: L. de Broglie Relativistic QM-function of the electron: 1928: P. Dirac Evaluation of the Dirac Function: 1930: E. Schrödinger c ‘ Zitterbewegung ‘

  15. The Physical Causes of Relativity 15 “Zitterbewegung” (Schrödinger) Completed Structure of an Elementary Particle: (de Broglie1924) (Dirac / Schrödinger1928/30) (Spin, mag. moment) orbit (Momentum law) (Relativity) No conflict with the electron experiments ‘

The Physical Causes of Relativity d 2 T ' c v g = = = - 1 / 1 2 T q c 17 Special Relativity: Measuring ‘c’  v At rest: Measurement of d and T: d = fixed ; T = 2d/c measured cm = 2d/T = c Lab in motion with v: d = fixed Measurement of d and T: T = d/(c-v) + d/(c+v) = 2cd/(c2 - v2) = 2d/c * 2 measured cm = 2d’/T’ with d’ = d/ i.e. the Lorentz - Factor T’ = T* measured cm = 2d’/T’ = 2d/T/  2 = c* 2 / 2= c ‘

  25. The Physical Causes of Relativity 25 The Shapiro-Experiment: Einstein‘s view: this is a seeming reduction of c c   c P=1/2 or 1 depending on direction ‘ /gravity

  26. The Physical Causes of Relativity  26 The gravitational field of the sun: P=1/2 or 1 depending on direction Einstein‘s view: the path ís straight but the space is curved The application of classical refraction yields for the vertex: Integrating deflection  from – to + yields: 1.75 arcsec …. with Newton: 0.88 arcsec Now: Acceleration at rest!! This was the great breakthrough for Einstein in 1919 (Solar eclipse)!! ‘ /gravity

  30. The Physical Causes of Relativity Riemann Geometry Field Equations 30 As a comparison: The Schwarzschild Solution derived with Einstein ‘

  31. The Physical Causes of Relativity 31 The Schwarzschild Solution derived without Einstein Reduced speed of light c for radial motion for tangential motion in radial direction Reduced field distance Lorentz Transformation(time-related) Speed split into radial/tangential portion Now Gravity: Schwarzschild Solution ‘ /gravity

  32. The Physical Causes of Relativity 32 What is Gravity? Gravity is the change of the speed of light ‘c’ in the vicinity of an object But: What is the physical reason for the change of the speed of light ‘c’ in the vicinity of an object? ‘ www.ag-physics.org

  33. The Physical Causes of Relativity 33 Why is ‘c’ reduced? --> by the perturbed path of a light-like particle c Force is the Strong Force This solves Quantum Gravity! Averagespeed < c Reduction of c independent of Radius independent of mass ‘ /gravity

The Physical Causes of Relativity 34 Gravitational Field of Light Particles at the Sun Light Particles(Photons) Gravitational field of the ‘Core’ Core The density of the light particles: c The number of light particles up to r: Observer Gravitational field of photons at r: r ‘ www.ag-physics.org /gravity

  35. The Physical Causes of Relativity 35 Gravitational Field of Light Particles at the Sun per Distance Photons (“dark matter”) dominate Core dominates Sun surface 3 kpc ‘ www.ag-physics.org /gravity

  37. The Physical Causes of Relativity 37 Summary What are the benefits of this model of gravity? The model can easily be understood The model explains:  The “only attracting” effect  The “Dark Matter” phenomenon The model maintains:  The classical (and naïve) understanding of space and time The model avoids:  Conflicts between gravity and quantum theory QUANTUM GRAVITY BECOMES OBSOLETE  The necessity of the Equivalence Principle (which is an fact derived here)  The force #4 assigned to gravity (non-existent; step towards a unified theory) ‘ ‘ www.ag-physics.org /gravity
