Agnes Wojtusiak answered on 10 Nov 2018:
It’s a ball of SO MUCH stuff all squeezed and crushed together so tight that gravity becomes so huge that it absorbs EVERYTHING – even light!

It is essentially a collapsed star where all the mass and been crushed to a point where the mass is so massive that the gravity prevents light escaping and anything else.
Gravity is a fascinating thing.

Why are black holes invisible?
Agnes commented on :
@JJ They’re invisible because their gravity is soooo strong that it’s pulling EVERYTHING into it – even light!
Anne commented on :
Because the force of gravity is so strong that nothing, not even light, can escape from a black hole. However we can work out that they’re there, because of their effects on the things we can see.
