  There are now at least eight experiments extending over more than 100 years
that have detected the anisotropy of the speed of light, implying the absolute
motion of the detecting apparatus through a dynamical space. This light-speed
anisotropy is consistent with relativistic effects and Lorentz symmetry,
contrary to prevailing beliefs in physics. The theoretical and experimental
evidence implies that physics has failed to realise the existence of a
dynamical 3-space, and that motion relative to that space is the cause of
various relativistic effects, as proposed by Lorentz in 1899. This has resulted
in a necessary generalisation of the Maxwell, Schrodinger and Dirac equations,
which then provide an explanation for gravity as an emergent phenomenon within
the new physics. From the generalised Dirac equation we show that the spacetime
formalism is derivable, but as merely a mathematical construct whose geodesics
arise from the trajectories of quantum wavepackets in the 3-space. However the
metric of this spacetime is shown not to satisfy the Hilbert-Einstein
equations, except in the special case of the Schwarzschild metric. Hence we
demonstrate that the successes of the General Relativity formalism have been
more illusory than real, that its successes are in fact quite limited, which
explains why it failed to account for the bore hole anomaly, the so-called
`dark matter' spiral galaxy rotation anomaly, the systematics of black hole
masses and so on. It also failed in that the dynamics of the 3-space is
determined by two fundamental constants, namely G and the fine structure
constant alpha.
