[Date Answered] May 3, 2010 [Questioner (age, location)] Albie (Indian) [Answer] Black holes are formed as the result of the collapse of a very massive star at its death. They can´t "appear" from nowhere. But let´s assume that they do, then the huge gravitational field of the black hole would surely atract the Earth towards the black hole. [Question] 
suppose a Blackhole appeared just 1cm from Earth,will Earth be safe or will Earth be sucked into the Blackhole?
