ABSTRACT
I extend my thanks to Professor Gerardus ‘t Hooft, Nobel Laureate in Physics, for making
more widely known my work on black hole theory, big bang cosmology, and Einstein’s
General Theory of Relativity, by means of his personal website, and for providing me
thereby with the opportunity to address the subject matter - supported by extensive
references to primary sources for further information - in relation to his many comments,
by means of this dedicated paper. The extensive mathematical appendices herein are not
prerequisite to understanding the text.Introduction
