The Boomerang experiment
has measured the CMB power spectrum, which places limits
on the geometry of space-time, as described in
"A measurement by BOOMERANG of multiple peaks in the
angular power spectrum of the cosmic microwave background,"
Netterfield et al. (ApJ, submitted).

Cosmic Microwave Background anisotropy measurement,"
