Black holes are bodies which can suck in anything due to its gravity.Every body on this earth has gravitational force.but, the extent of the force matters a lot.The gravity of any entity is attributed to its mass and how far it is from the other.Let's now do this expt.
Take a sheet of paper in your hand.keep your other hand at some distance ,with your palm facing the paper. Do u thnk your hand has got attracted to the paper.If you say no, its wrong.Though you could see your hand at the same distance, there is a tiny gravitational force acting between the body and the paper.But, here the distance moved is very less, that it is not visible to our naked eyes.
Now crush the paper .you could find that space occupied by the paper has reduced.its mass is same. neverthless, there is a gravitational force.but it is larger than before.now that the paper has shrunk in size and has so many cavities,faults etc .This has provided the path for any body in affinity to move even more closer. (ie.into the core of the paper)
This is the same concept happening even in black hole.The star is bigger in size.There is less room for any body to move in when it shrunks in size(with same mass)any object can intrude into its core.
