\section{Recent Developments of Relativity Theories}

\subsection{Loop Quantum Gravity (LQG)}

\subsection{Quantum Riemannian geometry (QRG)}
\PMlinkname{QRG}{QuantumRiemannianGeometry} represents a new approach to Quantum Gravity in terms of `deformed' Riemannian, quantum geometry.

\subsection{Penrose theories}


\subsection{Hawking theories}

\subsection{Globally covariant GR theories (GC-GR)}
\subsubsection{ECE}
(\PMlinkexternal{ECE}{http://www.aias.us/index.php?goto=showPageByTitle&amp;pageTitle=Table_of_differences_between_the_standard_model_and_ECE} is presented at the \PMlinkexternal{AIAS website}{http://www.aias.us/}).
