[Date Answered] August 21, 2009 [Questioner (age, location)] APARAJITH (India) [Answer] Theoretically, once you have passed the event horizon, it is not possible to escape the black hole. Under this premise, your question doesn't have an answer. [Question] 
gravity slows down time,so IF we reach the event horizon,the time will stop,then if we pass near a black hole and return to the earth then the time which passes on earth will be more than the time which passes on the spaceship.then if we keep passing the blackhole for a year,can we return to earth and find that 20 or so years have passed?
