1 A black hole has no hair. — John Wheeler

2 Please, please: Do the homework. Do the homework even if it is past due. Late penalty for Momentum through Equilibrium and Statics has been reduced retroactively to 1%/day.

3 Equal Areas in Equal Times = Conservation of Angular Momentum

4 Astronauts shown in the picture A] will drift toward the higher part of the space station, if they are above its center of gravity B] will drift toward the center of the space station, if they are above its center of gravity C] will remain in the same place in the space station, regardless of whether they are above or below the center of gravity

5 Gravity Bends Light Newton predicted that gravity would bend light. (In fact, he thought gravity caused refraction!) Einstein predicted gravity would bend light twice as much.

6 “View” of a Black Hole
