Hoping that u r from Maharashtra & know marathi, I advice u to read a book of Mr. Jayant Naralikar "Akashashi Jadale Nate". & u will get the good knowledge of the Blackhole - having tremendous density which can absorb the sunlight also
The idea of a "black hole" seems to generate a great deal of interest. But it has long been recognised the so-called black holes are (at darkest) dark grey. Other than that, almost anything we think we know about their internal workings is probably wrong.
Having some personal experience in the matter, I would advise against further investigation of black holes. My ex-wife caught me enflagrant with a black hole and it led to the violent application of a cast iron skillet to my cranium... Needless to say,the lights went out.
