What first photograph of black hole can reveal about space
A black hole is a cosmic abyss with gravity of such intensity that nothing, not even light, escapes it.

Professor Brian Greene of Columbia University and the World Science Festival provides context and talks to Judy Woodruff about this scientific breakthrough.
