The wrenching findings come from a correlation between two kinds of sky maps--one that denotes the positions of large numbers of galaxies and another, a snapshot of the cosmic microwave background, which is the remnant radiation from the Big Bang.
This remnant radiation is riddled with hot and cold spots, most of which reflect the lumpiness of the infant universe, from which galaxies grew.
The new evidence comes from the Arcminute Cosmology Bolometer Array Receiver (ACBAR), a South Pole network of 16 detectors that probes the temperature of the Big Bang's remnant radiation
, known as the cosmic microwave background.
Both experiments examine the cosmic microwave background, the remnant radiation
from the Big Bang that cooled to microwave energies as it traveled through space for some 13 billion years.
