The faint “echoes” of the Big Bang
It has been detected in the form of a cosmic microwave background radiation that pervades the hole Universe.
- background radiation – the temperature of the Big Bang has cooled to around +2.6ºC.
- In 1993, the first images of this radiation were produced by the Cosmic Background Explorer (COBE) spacecraft. (diagram)
- The COBE image shows the minute variations in temperature (pink = warmer / blue = cooler) that were predicted by the Big Bang theorists.
