Learned this in the second grade. im sure someone already announced it is the outcome of a neutron's core collapsing. I forget
all the details but is sucks in all matter. If you shined a light away from a black hole, the light would
actually bend towards the black hole. And black holes are invisible.
And there is a huge one in the middle of our universe.
And it will eventually eat the whole world like no other fat boy you have seen.
