  I have not come across this before but there are so many theories when it comes to black holes!
  
  It is thought that the matter that goes into a black hole gets crushed into a tiny point at the centre called a ‘singularity’. This is supposed to have zero size (I know sounds crazy, but so are black holes! ) but that does mean it’s tiny like a grain of sand. We believe that this singularity has an ‘infinite density’.
  
  Unfortunately because no-one has actually been to a black hole there is no definite answer to this question. The best way I’ve heard falling into a black hole being described is that your body would most closely resemble “toothpaste being squeezed out of the tube”. Lovely.
