    In case you don't want to download and skim the 105 page PDF, the questions are:

    What is the dark matter?
    What are the masses of the neutrinos, and how have they shaped the evolution of the universe?
    Are there additional spacetime dimensions?
    What is the nature of dark energy?
    Are protons unstable?
    How did the universe begin?
    Did Einstein have the last word on gravity?
    How do cosmic accelerators work and what are they accelerating?
    Are there new states of matter at exceedingly high density and temperature?
    Is a new theory of matter and light needed at the highest energies?
    How were the elements from iron to uranium made?

    The PDF gives a detailed explanation for each of these if you're interested: http://www.nationalacademies.org/bpa/reports/cpu/q 2c-public_release_version.pdf
