Black Hole

Black Hole A  black hole  is a region of  spacetime  exhibiting such strong  gravitational  effects that nothing—not even  particles  and  electromagnetic radiation  such as  light —can escape from inside it. [1]  The theory of  general relativity  predicts that a sufficiently compact  mass  can deform  spacetime  to form a black hole. [2] [3]  The boundary of the region from which no escape is possible is called the  event horizon . Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed. [4]  In many ways a black hole acts like an ideal  black body , as it reflects no light. Moreover,  quantum field theory in curved spacetime  predicts that event horizons emit  Hawking radiation , with  the same spectrum  as a black body of a temperature inve...

Apparently a lot of people have been interested in it other than me. And their interest has been a lot more active than mine. As it turns out everything that happens can be expressed as mathematical equations. Or at least people have been trying to. I knew “A brief history of time by Stephen Hawking” dwells on the subject too. I just chose to read this book because it had lesser number of pages. And I wanted a summary of the history of time and could do without the technicalities. But then, even this smaller book is quite dense. You need to have a healthy amount of curiosity to be able to get through this book. In the end, it doesn’t answer any specific question you might have on the universe. In fact, Stephen Hawking is blissfully diplomatic about most things. And the...
