1) Discuss how the uncertainty principle relates to a proton beam. This is the discussion we had in class about position and velocity.
2) Describe the role of curvature in Hawking radiation. What is important about the event horizon?
3) What is time dilation? Once we know about curvature in the Universe why should time dilation not be so surprising?
4) Is there a symmetry break involved in the process of Hawking radiation presented in class? Why or why not?
