Description
If we followed a hydrogen proton around, waiting to see the thermonuclear fusion that produces starlight, we'd likely have to wait a few billion years. From there, however, it's just a 20,000-year hop, skip, and a jump away to producing helium-4. But put away your folding chair and that addictive smartphone game; this Princeton astrophysicist can take you through this solar tourist attraction in half an hour.
