Nothing happens just might get a little crusty :D i assume u are talking about your belly button just be sure to wash it
It gets a colostomy, a opening on the belly where they put the colon and attach a bag to it.
It will fall into the black hole. The same happens if something gets too close the Sun, for example - it will fall into the Sun.
Infection
death
It gets bent toward the black hole's singularity.
Objects which approach a black hole will get sucked into it.
the hole stretches and sags. like your skin. elbows. knees.
Your life will be over in an instant
The matter gets crushed as tiny as it can get.
It will tear itself out of your body ripping a huge hole in your belly to escape from the torment you put it through.
it gets covered with cement.
As big as your belly button.
