Whichever problem is being worked on by the physicist of whom you ask the question. There's no shortage of good candidates.
1. Unification of gravitation with quantum chromodynamics.
2. Where did it all come from?
3. Why does matter exert a gravitational force? Why does a charge have an electric field?
4. Why do the fundamental constants have the values they have? Why do the forces have the strengths they have?
5. Why do we have the set of particles that we have?
6. Why do we have the laws of physics that we have?
7. Can we come up with a string theory or M-brane theory that matches physical reality and gives us some insight?
8. Why is it so hard to get students to learn even simple physics? Why is it so hard to get teachers to do a good job teaching physics?
