Stephen Crothers presented the case that Black Holes and the Big Bang have been created by theorists and never observed. Black Holes are now said to be both invisible and visible. Quasars are now black holes; so are the ‘blazars’. Individual black holes are also alleged x-ray sources. It is claimed that galaxies harbor a super-massive black hole at their centers, along with other black holes dispersed throughout them. All these black holes exist in an alleged expanding big bang universe. However, black hole universes are inconsistent with big bang universes. The audience were taken through the salient facts one step at a time in this riveting mostly non-mathematical presentation. The math of General Relativity has a notorious reputation for its complexity but most of the important facts can be understood by the layman and specialist alike without any mathematics.
Crothers is a preeminent mathematician, counted among the most competent critics of modern cosmology (including both the General Theory of Relativity and popular theory of the Big Bang). He has also gained much attention for his systematic unraveling of standard Black Hole theory, showing that the mathematical model of a Black Hole follows neither from observation nor from any logical reasoning from Einstein’s General Theory of Relativity.
