Why in news
The article highlights how a failed 1970s CSIRO experiment to detect exploding black holes led to the development of Fast Fourier Transform techniques now essential for Wi-Fi and Bluetooth.
Background
In the late 1970s, Australian radio astronomers from the CSIRO attempted to detect exploding black holes. The experiment failed its primary goal but resulted in mathematical techniques to filter cosmic noise and mitigate multipath interference.
Facts for Prelims
- S&TCSIRO: Australia's national science agency responsible for the original radio astronomy research.
