1. What’s inside a black hole?
2. What’s the Universe expanding into?
3. What is dark energy?
4. What’s dark matter made of?
5. Where is all the antimatter?
6. What happened in the first 10^-43 seconds of the Universe?

8. What causes fast radio bursts?
9. Why does the Sun’s magnetic field flip?*
10. Does life exist on other planets?
