The Essence of the Universe

Volume I
The Fundamental Reason for the Constancy of the Speed of Light
and the Absoluteness of Time

Part 1

Chapter 1 Motivation and background
1.1 The two intriguing questions
? Why the speed of light is always constant?
? What if we alter the direction of the propagation of light in the 'thought
experiment?'
1.2 The origin of the two principles
? The principle of special relativity
? The principle of the constancy of the speed of light
1.3 An implication from the result of Michelson and Morley experiment
1.4 Wave property of light

Chapter 2 Revisiting the theory of special relativity
2.1 The relativity of simultaneity
2.2 The derivation of time dilation
2.3 Einstein's approach
2.4 Length contraction
2.5 The equivalence of mass and energy:

Chapter 3 Other coordinate transformations and velocity-additive-law
3.1 Galilean transformation
3.2 Lorentz transformation
3.3 Velocity-additive-law derived from Lorentz transformation
3.4 The relativistic mass
3.5 The conformity of the coordinate transformations to the principle of relativity on Maxwell's wave equation
? Unconformity of Galilean transformation
? Conformity of Lorentz transformation

Part 2

Chapter 4 The thought experiment is not appropriate for deducing the effect
of time dilation
4.1 The equivalence of the three approaches: Einstein's approach, Lorentz
transformation, and the thought experiment with
4.2 A flaw in the thought experiment
4.3 Neither Einstein's approach nor Lorentz transformation is suitable for deducing
the effect of time dilation
4.4 A rigorous proof that the effect of time dilation does not exist in a body
moving at constant velocity

Chapter 5 A new coordinate transformation between the two inertial frames
and
5.1 A new coordinate transformation
5.2 Conformity of the new transformation to the principle of relativity on Maxwell's wave equation
5.3 A brief summary on the three coordinate transformations

Chapter 6 The electric and magnetic forces that are the different representations of the same phenomenon - with the ‘velocity-additive-law’ derived from the new coordinate transformation
6.1 When the effect of length contraction is used
6.2 When the velocity-additive-law derived from the new coordinate transformation is used
