Accelerated Reference Frames,ly this formalism to deduce the spatial geometry in a rotating reference frame and discuss Ehrenfest’s paradox. Also we show that it is impossible to Einstein synchronize clocks around a closed path in a rotating frame because this leads to a contradiction in a non-rotating frame. Gravitational time

Covariant Differentiation,derivative of a form is a form. Hence in this chapter we first introduce the covariant derivative and then the antisymmetric exterior derivative. The relativistic Euler–Lagrange equations are introduced and applied to deduce the equation of motion of free particles in curved spacetime—the geodesic e

Curvature,nts is deduced. Tidal forces are discussed in a relativistic context, and it is pointed out that the relativistic gravitational field has both a non-tidal component due to the motion of the reference frame and a tidal component due to spacetime curvature.

The Linear Field Approximation and Gravitational Waves,ell are deduced. It is shown that inertial dragging is a consequence of the general theory of relativity. The equations of gravitomagnetism are deduced. Gravitational waves are described and related to their detection by the LIGO-detectors.

Sources of Gravitational Fields,of Einstein’s field equations inside an incompressible star—the internal Schwarzschild solution. Furthermore we shall present Israel’s formalism for describing singular mass shells in the general theory of relativity, and apply this first to a shell consisting of dust particles, and then to find a s

Cosmology,on law is found as a general property of these models. It is shown that the cosmic redshift due to the expansion of the space contains both the kinematic Doppler effect due to the velocity of the emitter relative to the observer and the gravitational shift of wavelength for light moving vertically i
