SUMMARY

The peak wavelength of the Cosmic Microwave Background (CMB) when the scale factor R=0.5 corresponds to a temperature of approximately 5800 K. This calculation utilizes Wien's Displacement Law, which states that the peak wavelength is inversely proportional to temperature. Regarding the quarks Susan and Nick, their potential fates about an hour into the universe's age include forming baryons, such as protons and neutrons, or participating in interactions that lead to the formation of light elements during nucleosynthesis.

PREREQUISITES
  • Understanding of Wien's Displacement Law
  • Basic knowledge of quantum chromodynamics (QCD)
  • Familiarity with the Big Bang nucleosynthesis process
  • Concept of cosmic scale factors in cosmology
NEXT STEPS
  • Research Wien's Displacement Law and its applications in cosmology
  • Study quantum chromodynamics and its role in particle physics
  • Explore the process of Big Bang nucleosynthesis in detail
  • Investigate the implications of cosmic scale factors on the evolution of the universe
USEFUL FOR

Astronomy students, cosmologists, and physicists interested in the early universe and particle interactions.

Hi, can anyone help me solve the following questions?

1.What was the peak wavelength of the CMB when R=0.5?
a. What temperature does this correspond to?

2. Two quarks named Susan and Nick existed in the early universe. Susan
became part of a proton and Nick became part of a neutron. What are
two potential fates for both Susan and Nick about an hour into the age of the
universe?
