The following questions are addressed in this chapter. They are better discussed in a group to allow a variety of opinions to emerge. The relevant section link is given after each question:
1. Are mass and charge related? (QR4.3.2)
2. Why are electrons and neutrinos both leptons? (QR4.3.3)
3. Why do neutrinos have a tiny mass but no charge? (QR4.3.3)
4. Why is our universe made of matter instead of anti-matter? (QR4.3.5)
5. Anti-particles run our time in reverse, so can they go backwards in time? (QR4.3.6)
6. Why do quarks have strange one-third charges? (QR4.4.3)
7. What causes the force that binds together the nucleus of an atom? (QR4.4.4)
8. Why does this force increase with distance? (QR4.4.4)
9. Why are three quarks needed to form a proton or neutron? (QR4.4.5)
10. What do the quark colors of the standard model represent? (QR4.4.5)
11. What makes neutrons in space decay into protons? Why don’t protons decay? (QR4.4.6)
12. The Higgs doesn’t cause any of the mass around us, so what mass does it cause? (QR4.4.7)
13. E = mc2, but why does the energy of matter depend on the speed of light? (QR4.4.8)
14. Why does string theory need eleven dimensions to work? (QR4.5.1)
15. What did Newton think caused gravity? Does current physics agree? What does the evidence suggest? (QR4.5.2)
16. Why are virtual particles magical despite having lawful effects? (QR4.5.2)
17. How does current physics decide when virtual particles interact? (QR4.5.3)
18. How does the standard model explain new and unexpected findings? (QR4.5.4)
19. What is the difference between an equation and a theory? (QR4.5.5)
20. How is the standard model of physics similar to the standard model of medieval astronomy? (QR4.5.6)
21. Are the standard model’s fundamental particles actually particles? Are they fundamental? Explain. (QR4.5.7)
22. How does a processing model classify the basic entities of physics? (QR4.5.8)
23. Why does quantum realism’s claim that matter is made of light contradict the standard model? (QR4.5.9)
24. What came first, matter or light? Give a reason for your answer (QR4.5.9)
25. Why do all higher atomic nuclei need neutrons? (QR4.6.1)
26. An atom of lead has 82 electrons in a small space, so why don’t they collide with each other? (QR4.6.2)
27. How do electrons fill the shells and sub-shells of an atom? (QR4.6.3)
28. Can electrons as point-particles spin? Why do electrons half-spin? (QR4.7.1)
29. Why are neutrinos always left-handed? (QR4.7.2)

31. Why is the universe charge neutral? (QR4.7.4)
32. Why do leptons and quarks have three family generations, then no more? (QR4.7.5)
33. Why are the higher generations of leptons and quarks increasingly heavy? (QR4.7.5)
34. What is dark matter? Why can’t we see it? How does it differ from ordinary matter? (QR4.7.6)
35. What is dark energy? Why can’t a particle model explain it? (QR4.7.7)
36. Is our universe dead or alive? Give reasons. (QR4.8.1)
37. Is our universe finely tuned for life? (QR4.8.2)
38. What are the quantum evolution equivalents of biology’s reproduction, variation and selection? (QR4.8.3)
