- What is dark energy?
- How were the heavy elements from iron to uranium made?
- Do neutrinos have mass?
- Where do ultrahigh-energy particles come from?
- Is a new theory of light and matter needed to explain what happens at very high energies and temperatures?
- Are there new states of matter at ultrahigh temperatures and densities?
- Are protons unstable?
- What is gravity?
- Are there additional dimensions?
- How did the universe begin?
