Don't let the name fool you. Black hole is anything but the empty space.
It is a super-massive star that goes off, loses its gravity and falls to the end of nowhere.
It sucks everything around it.
It is pitch black, not ever a light can get through.
It wiped off its trace, then it is gone.
Have you ever feel being like the dead star?
On a one fine day, you suddenly lost your gravity and fall to the deepest ground.
Being sucked and sucks everything around you.
So deep you will lost your breath and falls deeper and deeper and deeper.
You go down under to the bottomless you don't know where you are, what to do, what to feel.
To me, black hole comes in a form of a test pack.
