Which physics relationship is more important?

How the increase in temperature vs. depth for Earth (creates the "oil window"--7,500 feet to 15,000 feet--where dead organisms were cooked into oil).
How the arrangement of carbon's four outer electrons enables the wild variety of carbon compounds, especially those essential for life.



Which unanswered question in physics is more important?

How can we explain the "Pioneer Anomaly?"
Do quarks and leptons have internal structure? (Protons and neutrons are made of quarks; the electron is a lepton.)
