Age of Univ is 13.7 B  (within 1%)
 
10-5 seconds:  protons and neutrons form from quarks.
 
.01 to 300 seconds:  atomic nuclei form of helium, lithium, and heavy hydrogen.
 
Only at age 380,000 years did Univ become transparent.  That's when electrons became bound
to nuclei to create atoms.  Before that photons could interact with electrons and scatter.
 
300,000,000 years:  first stars and galaxies form.
 
1 B years:  limit of current observation:  highest redshift.
 
 
 
Ordinary matter is just 4.5% of total matter; the rest is dark matter and dark energy.
 
see pie chart page 40;  gas is 4%; stars and planets  .5%;  dark matter 24% and dark enerygy is 71.5%.
 
Measured amount of deuterium implies that ord matter = 4.5%.
 
Also,  CMB  (cosmic microwave background) measured at age of 380,000 years implies that 
ord matter is also 4.5%.
 
Dark matter interacts weakly with ord matter.
 
page 41   Inflation leads to a profound connection btwn quarks and the cosmos:  quantum fluctuation in the
inflation field on the subatomic scale get blown up to astrophysical size by the rapid expansion and become
the seeds of structures we see today.
 
The pattern seen in the CMB sky is a giant image of the subatomic world.
