More WMAP results &
images from Max Tegmark
2003 Feb
and the answers are: Age=13.7 Gyr (+/-1%); Geometry Flat;
Baryons 4%, Dark Matter 23%, Dark Energy 73%;
H0 = 71 km/s/Mpc (+/-5%); Support for Inflation,
Dark Energy more like cosmological constant than Quintessence
CMB ripples made 3.8x105 yrs after BB,
First Stars made 200x106 yrs after BB (!)
2002 Dec
New preprint
from the BOOMMERanG team
reporting continued support for inflation (flat
universe 13.5 Gyr old;
5% baryonic matter, 30% cold dark matter, &
65% dark energy;
scale invariant initial density perturbations).

[Undoubtedly there will continue to be numerous & frequent
advances since the end of the course. However only the most
"dramatic", significant will be noted here]
