Studying Black Holes in a Bathtub

Mysterious black holes, thought to reside in the center of every galaxy, are difficult to study because even the closest one, in the center of our own Milky Way, is still some 27,000 light years away. But researchers at the University of Nottingham's Quantum Gravity Laboratory have found that some of the physical phenomena linked to black holes can be studied in an ordinary bathtub. VOA's George Putic has more.
