What are Black Holes?

In the very hearts of galaxies, like our Milky Way, lurk giant black holes that sometimes evolve into monstrous powerhouses of light. How do we know that they exist? How are they born? How do they grow? Are they important in the ‘big picture’?

I had a great relationship with them. The air in the classroom was of love, trust and wonder!
