Evidence of Black Holes from the principles of defused parallel light
Today’s weather was sort of average for the time of year today not windy not sunny not wet not warm and not cold, so not really a lot more to say on the subject then . . . . . . I can hear many a person going PHEW again. But while I was out looking at the weather I spotted a blocked hole (sorry a black hole, the blocked hole was ignored today). Now I know it’s Sunday and most of you do not wish to hear about the weather or science but guess what I need to discuss a bit of science now.
As we know black holes are incredibly dense so dense that their gravitational pull will suck in light. So in reality you can’t see a black hole. It gets even more confusing because at a certain distance away from a black hole the light passing it will be bent round the black hole like a magnifying glass and the light from any object behind the black hole will be focused to a point at a certain distance the other side of the black hole (I hope you are all still with me on this). If you are not at the exact focal point of the object but close to it you will get a slightly out of focus image of the object, and as I’m sure you are all aware of the principles of defused parallel light passing through an atmosphere you will all then be aware that the image will form a small cross. ……
So I think I am able to say with some certainty that I did see evidence of a black hole above the house earlier, luckily I was also able to take a photograph of this because I was taking a photograph of the sunset at the time. Anyway the image moved across the sky as one would expect because the black hole and the object behind the black hole and planet Earth are all moving at different speeds, in fact I would say that was the final conclusive proof. The dog foolishly suggested it was an aeroplane but he is a dog and dogs have a completely different idea about black holes, the dog thinks the muddy damp cold hole in the garden is a black hole . . . . . . . . . OK it is but it does not suck everything into it including light and me . . . . . . . . OK it does but it not a real black hole . . . . . . . . OK YES YES I know yes it is . . . . . . Ya Sucks Boo……
