The Media is currently – April 2019 ev – awash, agog, with reports and images about a supposedly cosmic “Black Hole”.
Yet all the trumpeted image reveals is a dark region of outer space in which an irregular visible object has at its centre a dark region of outer space indistinguishable from the dark region which surrounds that irregular visible object. That is, there is nothing in such an image to suggest such a hypothetical cosmic “Black Hole”.
Which objective, logical, analysis, of such an image does not prevent the Media – and even many scientists – from claiming that the image is “evidence” of the existence of cosmic “Black Holes”. Which rather calls into question the objectively – the rational scepticism – of those scientists who apparently accept without question that such theoretical cosmic “Black Holes” exist and who project their ideas onto some fuzzy astronomical image.
Where are the rational sceptics who demand real experimental, repeatable, proof of some physical or of some cosmological exotic theory? Rational sceptics and experimental, repeatable, proof that formed and forms the basis of Western science.
