Leading astronomers will present new findings on the content and
structure of the early universe at a National Science Foundation
press conference May 23. Alan Guth of MIT, who originated the
inflation theory, will participate.

The press conference will focus on images from the Cosmic
Background Imager (CBI), an interferometer that detects the
cosmic microwave background–the radiation that began its journey
to Earth shortly after the Big Bang. CBI is located at 16,000
feet in the Atacama Desert of Chile, one of the driest on Earth.
The project is funded by the National Science Foundation and
California Institute of Technology.

The press conference will include a discussion of how cosmic
microwave background observations are helping to test
cosmological theories and determine parameters such as the amount
of dark matter and dark energy in the universe.
